Kubernetes with ACS and Deis simple deployment scripts

createk8s.sh - bash script with parameters to create Kubertentes cluster at Azure Container Services
createdeis.sh - bash script with parameters to create Deis Workflow on created Kuberntetes cluster (use the same prameters as createk8s.sh)

Change the following parameters to use for your test:

Purpose	Parameter	Current value in scripts
Azure Resource Group name	AZURE_RG_NAME	stas-k8s-rg
Azure DC Location	AZURE_DC_LOCATION	southcentralus
Azure Container Service name	AZURE_SERVICE_NAME	stas-k8s-acs
Azure DNS Prefix for Azure Container Service	AZURE_DNS_PREFIX	stas-k8s
Azure Storage Account name for DEIS usage	AZURE_SA_NAME	stask8sdeisstorage

You need have installed the following utils to use this scripts

Before run the scripts you need to perform login to your Azure subscripion with Azure CLI using the following command:

az login

Don't forgert to mark the scripts as executable:

sudo chmod +x createk8s.sh
sudo chmod +x createdeis.sh

Azure CLI 2.0
az - https://docs.microsoft.com/en-us/cli/azure/install-azure-cli

Kubernetes command-line tool
kubectl - https://kubernetes.io/docs/tasks/kubectl/install/

Helm is a tool for managing Kubernetes charts. Charts are packages of pre-configured Kubernetes resources
helm - https://github.com/kubernetes/helm/blob/master/docs/install.md

The Deis command-line interface (CLI)
deis - http://docs.deis.io/en/latest/using_deis/install-client/

Test Deis installation

To test the deployment you need to find a right hostname to use with deis CLI.
Execute the following command to find EXTERNAL IP of your Kubernetes cluster:

kubectl --namespace=deis get service deis-router

You results will look like this one:

 NAME          CLUSTER-IP    EXTERNAL-IP    PORT(S)                                                    AGE
 deis-router   10.0.113.22   1.1.1.1        80:31912/TCP,443:31642/TCP,2222:31239/TCP,9090:32507/TCP   5m
 

Use EXTERNAL-IP value to build the hostname to access Deis. It will be:

deis.EXTERNAL-IP.nip.io

For example, for the output above it is:

 deis.1.1.1.1.nip.io

To deploy your first app you need to register on Deis using following command:

deis register http://deis.EXTERNAL-IP.nip.io 

Example output:

stas@ubuntuserver:~$ deis register http://deis.1.1.1.1.nip.io
username: admin
password:
password (confirm):
email: [email protected]
Registered admin
Logged in as admin
Configuration file written to /home/stas/.deis/client.json

As the first registered user you will receive adminstrative priveleges.
Check that you set all right executing following command:

deis whoami

Example output:

 stas@ubuntuserver:~$ deis whoami
 You are admin at http://deis.1.1.1.1.nip.io
 

And finally add your ssh pub key to Deis:

 deis keys:add ~/.ssh/id_rsa.pub

Great! So now your ready to deploy your first app to Deis.

To test Deis installation you can use the follwing guides:
For Applications - https://deis.com/docs/workflow/quickstart/deploy-an-app/
For Containers - https://deis.com/docs/workflow/applications/using-dockerfiles/

Or you can use prepared testdeis.sh script. Don't forgert to mark the scripts as executable:

sudo chmod +x testdeis.sh

After the script execution my-first-deis-app was created. You can check it by using the following command:

curl http://my-first-deis-app.deis.EXTERNAL-IP.nip.io  

where EXTERNAL-IP is the EXTERNAL-IP of deis-router you detected before.
Example output:

stas@ubuntuserver:~/example-go$ curl http://my-first-deis-app.deis.1.1.1.1.nip.io
