Preparing environment for DataLab deployment
How to setup local development environment
DataLab is an essential toolset for analytics. It is a self-service Web Console, used to create and manage exploratory environments. It allows teams to spin up analytical environments with best of breed open-source tools just with a single click of the mouse. Once established, environment can be managed by an analytical team itself, leveraging simple and easy-to-use Web Interface.

The following diagram demonstrate high-level logical architecture.
The diagram shows main components of DataLab, which is a self-service for the infrastructure deployment and interaction with it. The purpose of each component is described below.
Self-Service is a service, which provides RESTful user API with Web User Interface for data scientist. It tightly interacts with Provisioning Service and Database. Self-Service delegates all user`s requests to Provisioning Service. After execution of certain request from Self-service, Provisioning Service returns response about corresponding action happened with particular resource. Self-service, then, saves this response into Database. So, each time Self-Service receives request about status of provisioned infrastructure resources – it loads it from Database and propagates to Web UI.
Billing is a module, which provides a loading of the billing report for the environment to the database. It can be running as part of the Self-Service or a separate process.
The Provisioning Service is a RESTful service, which provides APIs for provisioning of the user’s infrastructure. Provisioning Service receives the request from Self-Service, afterwards it forms and sends a command to the docker to execute requested action. Docker executes the command and generates a response.json file. Provisioning service analyzes response.json and responds to initial request of Self-Service, providing status-related information of the instance.
Security Service is RESTful service, which provides authorization API for Self-Service and Provisioning Service via LDAP.
Docker is an infrastructure-provisioning module based on Docker service, which provides low-level actions for infrastructure management.
Database serves as a storage with description of user infrastructure, user’s settings and service information.
The following diagrams demonstrate high-level physical architecture of DataLab in AWS, GCP and Azure.
- Self-service node (SSN)
- Endpoint node
- Edge node
- Notebook node (Jupyter, Rstudio, etc.)
- Data engine cluster
- Data engine cluster as a service provided with Cloud
Creation of self-service node – is the first step for deploying DataLab. SSN is a main server with following pre-installed services:
- DataLab Web UI – is Web user interface for managing/deploying all components of DataLab. It is accessible by the following URL: http[s]://SSN_Public_IP_or_Public_DNS
- MongoDB – is a database, which contains part of DataLab’s configuration, user’s exploratory environments description as well as user’s preferences.
- Docker – used for building DataLab Docker containers, which will be used for provisioning other components.
Elastic(Static) IP address is assigned to an SSN Node, so you are free to stop|start it and and SSN node's IP address won’t change.
This is a node which serves as a provisioning endpoint for DataLab resources. Endpoint machine is deployed separately from DataLab installation and can be even deployed on a different cloud.
This node is used as a reverse-proxy server for the user. Through Edge node users can access Notebook via HTTPS. Edge Node has a Nginx reverse-proxy pre-installed.
The next step is setting up a Notebook node (or a Notebook server). It is a server with pre-installed applications and libraries for data processing, data cleaning and transformations, numerical simulations, statistical modeling, machine learning, etc. Following analytical tools are currently supported in DataLab and can be installed on a Notebook node:
- Jupyter
- Jupyterlab
- RStudio
- Apache Zeppelin
- TensorFlow + Jupyter
- TensorFlow + RStudio
- Deep Learning + Jupyter
Apache Spark is also installed for each of the analytical tools above.
Note: terms 'Apache Zeppelin' and 'Apache Spark' hereinafter may be referred to as 'Zeppelin' and 'Spark' respectively or may have original reference.
After deploying Notebook node, user can create one of the cluster for it:
- Data engine - Spark standalone cluster
- Data engine service - cloud managed cluster platform (EMR for AWS or Dataproc for GCP) That simplifies running big data frameworks, such as Apache Hadoop and Apache Spark to process and analyze vast amounts of data. Adding cluster is not mandatory and is only needed in case additional computational resources are required for job execution.
DataLab’s SSN node main directory structure is as follows:
/opt
└───datalab
├───conf
├───sources
├───template
├───tmp
│ └───result
└───webapp
- conf – contains configuration for DataLab Web UI and back-end services;
- sources – contains all Docker/Python scripts, templates and files for provisioning;
- template – docker’s templates;
- tmp –temporary directory of DataLab;
- tmp/result – temporary directory for Docker’s response files;
- webapp – contains all .jar files for DataLab Web UI and back-end services.
SSN node structure of log directory is as follows:
/var
└───opt
└───datalab
└───log
├───dataengine
├───dateengine-service
├───edge
├───notebook
├───project
└───ssn
These directories contain the log files for each template and for DataLab back-end services.
- ssn – contains logs of back-end services;
- provisioning.log – Provisioning Service log file;
- security.log – Security Service log file;
- selfservice.log – Self-Service log file;
- edge, notebook, dataengine, dataengine-service – contains logs of Python scripts.
Keycloak is used to manage user authentication instead of the aplication. To use existing server following parameters must be specified either when running DataLab deployment script or in /opt/datalab/conf/self-service.yml and /opt/datalab/conf/provisioning.yml files on SSN node.
| Parameter | Description/Value |

After creating endpoint, you must set the endpoint in Datalab UI. To do this, go to the tab "Resources" - "Endpoints". In the Name field, you should specify the name of the endpoint, in the URL, specify the network address of the endpoint (taking as an example https://0.0.0.0:8084/). In the Account field, you need to specify the "endpoint_id" value that was specified when creating the endpoint (for example, awstest, azuretest or gcptest), in the Endpoint tag field, specify the endpoint tag (optional).
Gateway node (or an Edge node) is an instance(virtual machine) provisioned in a public subnet. It serves as an entry point for accessing user’s personal analytical environment. It is created by an end-user, whose public key will be uploaded there. Only via Edge node, DataLab user can access such application resources as notebook servers and dataengine clusters. Also, Edge Node is used to setup SOCKS proxy to access notebook servers via Web UI and SSH. Elastic(Static) IP address is assigned to an Edge Node.
In order to create Edge node using DataLab Web UI – login and, click on the button “Upload” (Depending on authorization provider that was chosen on deployment stage, user may be taken from LDAP or from Azure AD (Oauth2)). Choose user’s SSH public key and after that click on the button “Create”. Edge node will be deployed and corresponding instance (virtual machine) will be started.

DataLab configuration files are located on SSN node by following path:
- /opt/datalab/conf ssn.yml – basic configuration for all java services;
- provisioning.yml – Provisioning Service configuration file;for
- security.yml – Security Service configuration file;
- self-service.yml – Self-Service configuration file.
All DataLab services running as OS services and have next syntax for starting and stopping:
sudo supervisorctl {start | stop | status} [all | provserv | secserv | ui]
- start – starting service or services;
- stop – stopping service or services;
- status – show status of service or services;
- all – execute command for all services, this option is default;
- provserv – execute command for Provisioning Service;
- secserv – execute command for Security Service;
- ui – execute command for Self-Service.
DataLab self service is listening to the secure 8443 port. This port is used for secure local communication with provisioning service.
There is also Nginx proxy server running on Self-Service node, which proxies remote connection to local 8443 port. Nginx server is listening to both 80 and 443 ports by default. It means that you could access self-service Web UI using non-secure connections (80 port) or secure (443 port).
Establishing connection using 443 port you should take into account that DataLab uses self-signed certificate from the box, however you are free to switch Nginx to use your own domain-verified certificate.
To disable non-secure connection please do the following:
- uncomment at /etc/nginx/conf.d/nginx_proxy.conf file rule that rewrites all requests from 80 to 443 port;
- reload/restart Nginx web server.
To use your own certificate please do the following:
- upload your certificate and key to Self-Service node;
- specify at /etc/nginx/conf.d/nginx_proxy.conf file the correct path to your new ssl_certificate and ssl_certificate_key;
- reload/restart Nginx web server.

Billing module is implemented as a separate jar file and can be running in the follow modes:
- part of Self-Service;
- separate system process;
- manual loading or use external scheduler;
The billing module is running as part of the Self-Service (if billing was switched ON before SSN deployment). For details please refer to section Self-Service Node. Otherwise, you should manually configure file billing.yml. See the descriptions how to do this in the configuration file. Please also note, that you should also add an entry in the Mongo database into collection:
{
"_id": "conf_tag_resource_id",
"Value": "<CONF_TAG_RESOURCE_ID>"
}
After you have configured the billing, you can run it as a process of Self-Service. To do this, in the configuration file self-service.yml set the property BillingSchedulerEnabled to true and restart the Self-Service:
sudo supervisorctl stop ui
sudo supervisorctl start ui
If you want to load report manually, or use external scheduler use following command:
java -jar /opt/datalab/webapp/lib/billing/billing-aws.x.y.jar --conf /opt/datalab/conf/billing.yml
or
java -cp /opt/datalab/webapp/lib/billing/billing-aws.x.y.jar com.epam.datalab.BillingTool --conf /opt/datalab/conf/billing.yml
If you want billing to work as a separate process from the Self-Service use following command:
java -cp /opt/datalab/webapp/lib/billing/billing-aws.x.y.jar com.epam.datalab.BillingScheduler --conf /opt/datalab/conf/billing.yml

Own GitLab server can be deployed from SSN node with script, which located in:
datalab_path/tmp/gitlab. Default: /opt/datalab/tmp/gitlab
All initial configuration parameters located in gitlab.ini file.
Some of parameters are already setuped from SSN provisioning.
GitLab uses the same LDAP server as DataLab.
To deploy Gitlab server, set all needed parameters in gitlab.ini and run script:
./gitlab_deploy.py --action [create/terminate]
Note: Terminate process uses node_name to find instance.
Note: GitLab wouldn't be terminated with all environment termination process.
If the parameter datalab_path of configuration file datalab.ini wasn’t changed, the path to DataLab service would default to:
- /opt/datalab/ - main directory of DataLab service
- /var/opt/datalab/log/ or /var/log/datalab/ - path to log files
To check logs of Docker containers run the following commands:
docker ps -a – to get list of containers which were executed.

docker logs <container_id> – to get log for particular Docker container.
To change Docker images on existing environment, you can run script on SSN node that rebuilds docker images with the command:
docker-build all #to rebuild all images
or
docker-build <notebook_name> #to rebuild certain images
You can also rebuild images manually by executing the following steps:
- SSH to SSN instance
- go to /opt/datalab/sources/
- Modify needed files [4]. [ONLY FOR AZURE] Copy service principal json file with credentials to base/azure_auth.json
- Rebuild proper Docker images, using one or several commands (depending on what files you’ve changed):
docker build --build-arg OS=<os_family> --file general/files/<cloud_provider>/base_Dockerfile -t docker.datalab-base .
docker build --build-arg OS=<os_family> --file general/files/<cloud_provider>/edge_Dockerfile -t docker.datalab-edge .

In order to start development of Front-end Web UI part of DataLab - Git repository should be cloned and the following packages should be installed:
- Git 1.7 or higher
- Python 2.7 with library Fabric v1.14.0
- Docker 1.12 - Infrastructure provisioning
Common is a module, which wraps set of reusable code over services. Commonly reused functionality is as follows:
- Models
- REST client
- Mongo persistence DAO
- Security models and DAO
Self-Service provides REST based API’s. It tightly interacts with Provisioning Service and Security Service and actually delegates most of user`s requests for execution.

Security service is REST based service for user authentication against LDAP/LDAP + AWS/Azure OAuth2 depending on module configuration and cloud provider. LDAP only provides with authentication end point that allows to verify authenticity of users against LDAP instance. If you use AWS cloud provider LDAP + AWS authentication could be useful as it allows to combine LDAP authentication and verification if user has any role in AWS account
DataLab provides OAuth2(client credentials and authorization code flow) security authorization mechanism for Azure users. This kind of authentication is required when you are going to use Data Lake. If Data Lake is not enabled you have two options LDAP or OAuth2 If OAuth2 is in use security-service validates user's permissions to configured permission scope(resource in Azure). If Data Lake is enabled default permission scope(can be configured manually after deploy DataLab) is Data Lake Store account so only if user has any role in scope of Data Lake Store Account resource he/she will be allowed to log in If Data Lake is disabled but Azure OAuth2 is in use default permission scope will be Resource Group where DataLab is created and only users who have any roles in the resource group will be allowed to log in.
Web UI sources are part of Self-Service.
Sources are located in datalab/services/self-service/src/main/resources/webapp
| Main pages | Components and Services |
|---|---|
| Login page | LoginComponent applicationSecurityService handles http calls and stores authentication tokens on the client and attaches the token to authenticated calls; healthStatusService and appRoutingService check instances states and redirect to appropriate page. |
| Home page (list of resources) | HomeComponent nested several main components like ResourcesGrid for notebooks data rendering and filtering, using custom MultiSelectDropdown component; multiple modal dialogs components used for new instances creation, displaying detailed info and actions confirmation. |
| Health Status page | HealthStatusComponent HealthStatusGridComponent displays list of instances, their types, statutes, ID’s and uses healthStatusService for handling main actions. |
| Help pages | Static pages that contains information and instructions on how to access Notebook Server and generate SSH key pair. Includes only NavbarComponent. |
| Error page | Simple static page letting users know that opened page does not exist. Includes only NavbarComponent. |
| Reporting page | ReportingComponent ReportingGridComponent displays billing detailed info with built-in filtering and DateRangePicker component for custom range filtering; uses BillingReportService for handling main actions and exports report data to .csv file. |

- Add system environment variable DATALAB_CONF_DIR=<datalab_root_folder>/datalab/infrastructure-provisioning/src/ssn/templates or create two symlinks in datalab/services/provisioning-service and datalab/services/self-service folders for file datalab/infrastructure-provisioning/src/ssn/templates/ssn.yml.
Unix
ln -s ../../infrastructure-provisioning/src/ssn/templates/ssn.yml ssn.yml
Windows
mklink ssn.yml ..\\..\\infrastructure-provisioning\\src\\ssn\\templates\\ssn.yml
- For Unix system create two folders and grant permission for writing:
/var/opt/datalab/log/ssn
/opt/datalab/tmp/result
- Download Node.js LTS from https://nodejs.org/en
- Install Node.js
- Make sure that the installation folder of Node.js has been added to the system environment variable PATH
- Install latest packages
npm install npm@latest -g
- Change folder to datalab/services/self-service/src/main/resources/webapp and install the dependencies from a package.json manifest
npm install
- Build web application
npm run build.prod
To enable a SSL connection the web server should have a Digital Certificate. To create a server certificate, follow these steps:
-
Create the keystore.
-
Export the certificate from the keystore.
-
Sign the certificate.
-
Import the certificate into a truststore: a repository of certificates used for verifying the certificates. A truststore typically contains more than one certificate.
Please find below set of commands to create certificate, depending on OS.
Pay attention that the last command has to be executed with administrative permissions. Use keytool bundled with JRE.
keytool -genkeypair -alias ssn -keyalg RSA -storepass KEYSTORE_PASSWORD -keypass KEYSTORE_PASSWORD -keystore ~/keys/ssn.keystore.jks -keysize 2048 -dname "CN=localhost"
keytool -exportcert -alias ssn -storepass KEYSTORE_PASSWORD -file ~/keys/ssn.crt -keystore ~/keys/ssn.keystore.jks
sudo keytool -importcert -trustcacerts -alias ssn -file ~/keys/ssn.crt -noprompt -storepass changeit -keystore ${JRE_HOME}/lib/security/cacerts
Pay attention that the last command has to be executed with administrative permissions. To achieve this the command line (cmd) should be ran with administrative permissions. Path to <DRIVE_LETTER>:\home%USERNAME%\keys should exist.
"%JRE_HOME%\bin\keytool" -genkeypair -alias ssn -keyalg RSA -storepass KEYSTORE_PASSWORD -keypass KEYSTORE_PASSWORD -keystore <DRIVE_LETTER>:\home\%USERNAME%\keys\ssn.keystore.jks -keysize 2048 -dname "CN=localhost"
"%JRE_HOME%\bin\keytool" -exportcert -alias ssn -storepass KEYSTORE_PASSWORD -file <DRIVE_LETTER>:\home\%USERNAME%\keys\ssn.crt -keystore <DRIVE_LETTER>:\home\%USERNAME%\keys\ssn.keystore.jks
"%JRE_HOME%\bin\keytool" -importcert -trustcacerts -alias ssn -file <DRIVE_LETTER>:\home\%USERNAME%\keys\ssn.crt -noprompt -storepass changeit -keystore "%JRE_HOME%\lib\security\cacerts"
Useful command
"%JRE_HOME%\bin\keytool" -list -alias ssn -storepass changeit -keystore "%JRE_HOME%\lib\security\cacerts"
"%JRE_HOME%\bin\keytool" -delete -alias ssn -storepass changeit -keystore "%JRE_HOME%\lib\security\cacerts"
Where the <DRIVE_LETTER> must be the drive letter where you run the DataLab.

There is a possibility to run Self-Service and Provisioning Service locally. All requests from Provisioning Service to Docker are mocked and instance creation status will be persisted to Mongo (only without real impact on Docker and AWS). Security Service can`t be running on local machine because of local LDAP mocking complexity.
Both services, Self-Service and Provisioning Service are dependent on datalab/provisioning-infrastructure/ssn/templates/ssn.yml configuration file. Both services have main functions as entry point, SelfServiceApplication for Self-Service and ProvisioningServiceApplication for Provisioning Service. Services could be started by running main methods of these classes. Both main functions require two arguments:
- Run mode (“server”)
- Configuration file name (“self-service.yml” or “provisioning.yml” depending on the service). Both files are located in root service directory. These configuration files contain service settings and are ready to use.
The services start up order does matter. Since Self-Service depends on Provisioning Service, the last should be started first and Self-Service afterwards. Services could be started from local IDEA (Eclipse or Intellij Idea) “Run” functionality of toolbox.
Run application flow is following:
- Create and run provisioning-service configuration:
-
Create Application with name provisining-service-application
- Main class:
com.epam.datalab.backendapi.ProvisioningServiceApplication - VM options:
-Ddocker.dir=[PATH_TO_PROJECT_DIR]\infrastructure-provisioning\src\general\files\aws - Program arguments :
server [PATH_TO_PROJECT_DIR]\services\provisioning-service\provisioning.yml - Working directory:
[PATH_TO_PROJECT_DIR] - Use classpath of module:
provisioning-servise - PAY ATTENTION: JRE should be the same jre where created server certificate
- Main class:
-
Create and run self-service configuration:
- Create Application with name self-service-application
- Main class:
com.epam.datalab.backendapi.SelfServiceApplication - Program arguments :
server [PATH_TO_PROJECT_DIR]/services/self-service/self-service.yml - Working directory:
[PATH_TO_PROJECT_DIR] - Use classpath of module:
self-service - PAY ATTENTION: JRE should be the same jre where created server certificate
- Main class:
- Create Application with name self-service-application

Each directory except general contains Python scripts, Docker files, templates, files for appropriate Docker image.
- base – Main Docker image. It is a common/base image for other ones.
- edge – Docker image for Edge node.
- dataengine – Docker image for dataengine cluster.
- dataengine-service – Docker image for dataengine-service cluster.
- general – OS and CLOUD dependent common source.
- ssn – Docker image for Self-Service node (SSN).
- jupyter/rstudio/zeppelin/tensor/deeplearning – Docker images for Notebook nodes.
All Python scripts, Docker files and other files, which are located in these directories, are OS and CLOUD independent.
OS, CLOUD dependent and common for few templates scripts, functions, files are located in general directory.
general
├───api – all available API
├───conf – DataLab configuration
├───files – OS/Cloud dependent files
├───lib – OS/Cloud dependent functions
├───scripts – OS/Cloud dependent Python scripts
└───templates – OS/Cloud dependent templates
These directories may contain differentiation by operating system (Debian/RedHat) or cloud provider (AWS).
Directories of templates (SSN, Edge etc.) contain only scripts, which are OS and CLOUD independent.
If script/function is OS or CLOUD dependent, it should be located in appropriate directory/library in general folder.
The following table describes mostly used scripts:
| Script name/Path | Description |
|---|---|
| Dockerfile | Used for building Docker images and represents which Python scripts, templates and other files are needed. Required for each template. |
| base/entrypoint.py | This file is executed by Docker. It is responsible for setting environment variables, which are passed from Docker and for executing appropriate actions (script in general/api/). |
| base/scripts/*.py | Scripts, which are OS independent and are used in each template. |
| general/api/*.py | API scripts, which execute appropriate function from fabfile.py. |
| template_name/fabfile.py | Is the main file for template and contains all functions, which can be used as template actions. |
| template_name/scripts/*.py | Python scripts, which are used for template. They are OS and CLOUD independent. |
| general/lib/aws/*.py | Contains all functions related to AWS. |
| general/lib/os/ | This directory is divided by type of OS. All OS dependent functions are located here. |
| general/lib/os/fab.py | Contains OS independent functions used for multiple templates. |
| general/scripts/ | Directory is divided by type of Cloud provider and OS. |
| general/scripts/aws/*.py | Scripts, which are executed from fabfiles and AWS-specific. The first part of file name defines to which template this script is related to. For example: common_*.py – can be executed from more than one template. ssn_*.py – are used for SSN template. edge_*.py – are used for Edge template. |
| general/scripts/os/*.py | Scripts, which are OS independent and can be executed from more than one template. |
Available Docker images and their actions:
| Docker image | Actions |
|---|---|
| ssn | create, terminate |
| edge | create, terminate, status, start, stop, recreate |
| jupyter/rstudio/zeppelin/tensor/deeplearning | create, terminate, start, stop, configure, list_libs, install_libs, git_creds |

- Docker command for building images docker.datalab-base and docker.datalab-ssn:
sudo docker build --build-arg OS=debian --file general/files/aws/base_Dockerfile -t docker.datalab-base . ;
sudo docker build --build-arg OS=debian --file general/files/aws/ssn_Dockerfile -t docker.datalab-ssn . ;
Example of SSN Docker file:
FROM docker.datalab-base:latest
ARG OS
COPY ssn/ /root/
COPY general/scripts/aws/ssn_* /root/scripts/
COPY general/lib/os/${OS}/ssn_lib.py /usr/lib/python3.8/datalab/ssn_lib.py

COPY general/templates/aws/jenkins_jobs /root/templates/jenkins_jobs
RUN chmod a+x /root/fabfile.py; \
chmod a+x /root/scripts/*
RUN mkdir /project_tree
COPY . /project_tree
Using this Docker file, all required scripts and files will be copied to Docker container.
- Docker command for building SSN:
docker run -i -v /root/KEYNAME.pem:/root/keys/KEYNAME.pem –v /web_app:/root/web_app -e "conf_os_family=debian" -e "conf_cloud_provider=aws" -e "conf_resource=ssn" -e "aws_ssn_instance_size=t2.medium" -e "aws_region=us-west-2" -e "aws_vpc_id=vpc-111111" -e "aws_subnet_id=subnet-111111" -e "aws_security_groups_ids=sg-11111,sg-22222,sg-33333" -e "conf_key_name=KEYNAME" -e "conf_service_base_name=datalab_test" -e "aws_access_key=Access_Key_ID" -e "aws_secret_access_key=Secret_Access_Key" -e "conf_tag_resource_id=datalab" docker.datalab-ssn --action create ;
- Docker executes entrypoint.py script with action create. Entrypoint.py will set environment variables, which were provided from Docker and execute general/api/create.py script:
elif args.action == 'create':
with hide('running'):
local("/bin/create.py")
- general/api/create.py will execute Fabric command with run action:
try:
local('cd /root; fab run')
- Function run() in file ssn/fabfile.py will be executed. It will run two scripts general/scripts/aws/ssn_prepare.py and general/scripts/aws/ssn_configure.py:
try:
local("~/scripts/{}.py".format('ssn_prepare'))
except Exception as err:
traceback.print_exc()
append_result("Failed preparing SSN node. Exception: " + str(err))
sys.exit(1)
try:
local("~/scripts/{}.py".format('ssn_configure'))
except Exception as err:
traceback.print_exc()
append_result("Failed configuring SSN node. Exception: " + str(err))
sys.exit(1)
- The scripts general/scripts/<cloud_provider>/ssn_prepare.py an general/scripts/<cloud_provider>/ssn_configure.py will execute other Python scripts/functions for:
- ssn_prepate.py: 1. Creating configuration file (for AWS) 2. Creating Cloud resources.
- ssn_configure.py: 1. Installing prerequisites 2. Installing required packages 3. Configuring Docker 4. Configuring DataLab Web UI
- If all scripts/function are executed successfully, Docker container will stop and SSN node will be created.
SSN:
docker run -i -v <key_path><key_name>.pem:/root/keys/<key_name>.pem -e "region=<region>" -e "conf_service_base_name=<Infrastructure_Tag>" -e “conf_resource=ssn" -e "aws_access_key=<Access_Key_ID>" -e "aws_secret_access_key=<Secret_Access_Key>" docker.datalab-ssn --action <action>
All parameters are listed in section "Self-ServiceNode" chapter.
Other images:
docker run -i -v /home/<user>/keys:/root/keys -v /opt/datalab/tmp/result:/response -v /var/opt/datalab/log/<image>:/logs/<image> -e <variable1> –e <variable2> docker.datalab-<image> --action <action>
First of all, a new directory should be created in infrastructure-provisioning/src/.
For example: infrastructure-provisioning/src/my-tool/
The following scripts/directories are required to be created in the template directory:
my-tool
├───scripts
└───fabfile.py
fabfile.py – the main script, which contains main functions for this template such as run, stop, terminate, etc.
Here is example of run() function for Jupyter Notebook node:
Path: infrastructure-provisioning/src/jupyter/fabfile.py
def run():
local_log_filename = "{}_{}_{}.log".format(os.environ['conf_resource'], os.environ['edge_user_name'], os.environ['request_id'])
local_log_filepath = "/logs/" + os.environ['conf_resource'] + "/" + local_log_filename
logging.basicConfig(format='%(levelname)-8s [%(asctime)s] %(message)s',
level=logging.DEBUG,
filename=local_log_filepath)
notebook_config = dict()
notebook_config['uuid'] = str(uuid.uuid4())[:5]
try:
params = "--uuid {}".format(notebook_config['uuid'])
local("~/scripts/{}.py {}".format('common_prepare_notebook', params))
except Exception as err:
traceback.print_exc()
append_result("Failed preparing Notebook node.", str(err))
sys.exit(1)
try:
params = "--uuid {}".format(notebook_config['uuid'])
local("~/scripts/{}.py {}".format('jupyter_configure', params))
except Exception as err:
traceback.print_exc()
append_result("Failed configuring Notebook node.", str(err))
sys.exit(1)
This function describes process of creating Jupyter node. It is divided into two parts – prepare and configure. Prepare part is common for all notebook templates and responsible for creating of necessary cloud resources, such as EC2 instances, etc. Configure part describes how the appropriate services will be installed.
To configure Jupyter node, the script jupyter_configure.py is executed. This script describes steps for configuring Jupyter node. In each step, the appropriate Python script is executed.
For example:
Path: infrastructure-provisioning/src/general/scripts/aws/jupyter_configure.py
try:
logging.info('[CONFIGURE JUPYTER NOTEBOOK INSTANCE]')
print('[CONFIGURE JUPYTER NOTEBOOK INSTANCE]')
params = "--hostname {} --keyfile {} --region {} --spark_version {} --hadoop_version {} --os_user {} --scala_version {}".\
format(instance_hostname, keyfile_name, os.environ['aws_region'], os.environ['notebook_spark_version'],
os.environ['notebook_hadoop_version'], os.environ['conf_os_user'],
os.environ['notebook_scala_version'])
try:
local("~/scripts/{}.py {}".format('configure_jupyter_node', params))
In this step, the script infrastructure-provisioning/src/jupyter/scripts/configure_jupyter_node.py will be executed.
Example of script infrastructure-provisioning/src/jupyter/scripts/configure_jupyter_node.py:
if __name__ == "__main__":
print("Configure connections")
env['connection_attempts'] = 100
env.key_filename = [args.keyfile]
env.host_string = args.os_user + '@' + args.hostname
print("Configuring notebook server.")
try:
if not exists(conn,'/home/' + args.os_user + '/.ensure_dir'):
conn.sudo('mkdir /home/' + args.os_user + '/.ensure_dir')
except:
sys.exit(1)
print("Mount additional volume")
prepare_disk(args.os_user)
print("Install Java")
ensure_jre_jdk(args.os_user)
This script call functions for configuring Jupyter node. If this function is OS dependent, it will be placed in infrastructure-provisioning/src/general/lib/<OS_family>/debian/notebook_lib.py
All functions in template directory (e.g. infrastructure-provisioning/src/my-tool/) should be OS and cloud independent.
All OS or cloud dependent functions should be placed in infrastructure-provisioning/src/general/lib/ directory.
The following steps are required for each Notebook node:
- Configure proxy on Notebook instance – the script infrastructure-provisioning/src/general/scripts/os/notebook_configure_proxy.py
- Installing user’s key – the script infrastructure-provisioning/src/base/scripts/install_user_key.py
Other scripts, responsible for configuring Jupyter node are placed in infrastructure-provisioning/src/jupyter/scripts/
-
scripts directory – contains all required configuration scripts.
-
infrastructure-provisioning/src/general/files/<cloud_provider>/my-tool_Dockerfile – used for building template Docker image and describes which files, scripts, templates are required and will be copied to template Docker image.
-
infrastructure-provisioning/src/general/files/<cloud_provider>/my-tool_descriptsion.json – JSON file for DataLab Web UI. In this file you can specify:
- exploratory_environment_shapes – list of EC2 shapes
- exploratory_environment_versions – description of template
Example of this file for Jupyter node for AWS cloud:
{
"exploratory_environment_shapes" :
{

}
]
}
Additionally, following directories could be created:
-
templates – directory for new templates;
-
files – directory for files used by newly added templates only;
All Docker images are being built while creating SSN node. To add newly created template, add it to the list of images in the following script:
Path: infrastructure-provisioning/src/general/scripts/aws/ssn_configure.py
try:
logging.info('[CONFIGURING DOCKER AT SSN INSTANCE]')
print('[CONFIGURING DOCKER AT SSN INSTANCE]')
additional_config = [{"name": "base", "tag": "latest"},
{"name": "edge", "tag": "latest"},
{"name": "jupyter", "tag": "latest"},
{"name": "rstudio", "tag": "latest"},
{"name": "zeppelin", "tag": "latest"},
{"name": "tensor", "tag": "latest"},
{"name": "emr", "tag": "latest"}]
For example:
...
{"name": "my-tool", "tag": "latest"},
...
There are a few popular LDAP distributions on the market like Active Directory, Open LDap. That’s why some differences in configuration appear. Also depending on customization, there might be differences in attributes configuration. For example the DN(distinguished name) may contain different attributes:
- DN=CN=Name Surname,OU=groups,OU=EPAM,DC=Company,DC=Cloud
- DN=UID=UID#53,OU=groups,OU=Company,DC=Company,DC=Cloud
CN vs UID.
The relation between users and groups also varies from vendor to vendor.
For example, in Open LDAP the group object may contain set (from 0 to many) attributes "memberuid" with values equal to user`s attribute “uid”.
However, in Active Directory the mappings are done based on other attributes. On a group size there is attribute "member" (from 0 to many values) and its value is user`s DN (distinguished name).
To fit the unified way of LDAP usage, we introduced configuration file with set of properties and customized scripts (python and JavaScript based). On backend side, all valuable attributes are further collected and passed to these scripts. To apply some customization it is required to update a few properties in security.yml and customize the scripts.
There are just a few properties based in which the customization could be done:
- ldapBindTemplate: uid=%s,ou=People,dc=example,dc=com
- ldapBindAttribute: uid
- ldapSearchAttribute: uid
Where the:
- ldapBindTemplate is a user`s DN template which should be filed with custom value. Here the template could be changed: uid=%s,ou=People,dc=example,dc=com -> cn=%s,ou=People,dc=example,dc=com.
- ldapBindAttribute - this is a major attribute, on which the DN is based on. Usually it is any of: uid or cn, or email.
- ldapSearchAttribute - another attribute, based on which users will be looked up in LDAP.
Additional parameters that are populated during deployment and may be changed in future are:
- ldapConnectionConfig.name: ldap user name
- ldapConnectionConfig.ldapHost: ldap host
- ldapConnectionConfig.ldapPort: ldap port
- ldapConnectionConfig.credentials: ldap credentials
There are 3 scripts in security.yml:
- userLookUp (python based) - responsible for user lookup in LDap and returns additional user`s attributes;
- userInfo (python based) - enriches user with additional data;
- groupInfo (javascript based) – responsible for mapping between users and groups;
The scripts above were created to flexibly manage user`s security configuration. They all are part of security.yml configuration. All scripts have following structure: - name - cache - expirationTimeMsec - scope - attributes - timeLimit - base - filter - searchResultProcessor: - language - code
Major properties are:
- attributes - list of attributes that will be retrieved from LDAP (-name, -cn, -uid, -member, etc);
- filter - the filter, based on which the object will be retrieved from LDAP;
- searchResultProcessor - optional. If only LDAP object attributes retrieving is required, this property should
be empty. For example, “userLookup” script only retrieves list of "attributes". Otherwise, code customization (like user enrichment, user to groups matching, etc.) should be added into sub-properties below:
- language - the script language - "python" or "JavaScript"
- code - the script code.
Configuration properties:
- ldapBindTemplate: 'cn=%s,ou=users,ou=alxn,dc=alexion,dc=cloud'
- ldapBindAttribute: cn
- ldapSearchAttribute: mail
Script code:
name: userLookUp
cache: true
expirationTimeMsec: 600000
scope: SUBTREE
attributes:
- cn
- gidNumber
- mail
- memberOf
timeLimit: 0
base: ou=users,ou=alxn,dc=alexion,dc=cloud
filter: "(&(objectCategory=person)(objectClass=user)(mail=%mail%))"
In the example above, the user login passed from GUI is a mail (ldapSearchAttribute: mail) and based on the filer (filter: "(&(objectCategory=person)(objectClass=user)(mail=%mail%))") so, the service would search user by its “mail”. If corresponding users are found - the script will return additional user`s attributes:
- cn
- gidNumber
- memberOf
User`s authentication into LDAP would be done for DN with following template ldapBindTemplate: 'cn=%s,ou=users,ou=alxn, dc=alexion,dc=cloud', where CN is attribute retrieved by “userLookUp” script.
DataLab supports OAuth2 authentication that is configured automatically in Security Service and Self Service after DataLab deployment. Please see explanation details about configuration parameters for Self Service and Security Service below. DataLab supports client credentials(username + password) and authorization code flow for authentication.
