You'll need to install pip, aws cli, cryptography, and fabric:
- pip: * https://pypi.python.org/pypi/pip
- aws cli:
* http://docs.aws.amazon.com/cli/latest/userguide/installing.html#install-with-pip
*
$ sudo pip install awscli
- fabric:
* http://www.fabfile.org/installing.html
*
$ sudo pip install fabric
Clone git repository:
https://github.com/cianfrocco-lab/cryoem-cloud-tools
Edit file cryoem-cloud-tools/aws/aws_init.sh to include AWS credentials. Consider moving out of cryoem-cloud-tools folder so that it does not get over written when you update the git repo.
With this file location, add the following line to your .cshrc / .bashrc / .bash_profile:
source /path/to/aws_init.sh
You will also need to include your AWS keypair path in aws_init.sh. Copy keypair into this new directory, double checking that this path is in the /home/[user]/.aws/aws_init.sh correctly. Also, make sure to modify permissions of file using:
$ chmod 600 /path/to/keypair.pem
For MacOSX users:
We compiled all python code into the directory aws_build_osx so that users do not need to install fabric (which sometimes can be a hassle).
- If you use this library on your Mac, use file aws_aliases_osx.sh instead of aws_aliases.sh in your aws_inith.sh script
- This repo also comes with Relion-2.0 pre-compiled for Mac (see below)
- Relion-2.0: We also included a compiled Relion-2.0 version compatible for Mac OSX that can be found in cryoem-cloud-tools/external_software/relion-2.0-mac
In using these wrappers, we typically use only a few of the commands for booting up & terminating instances.
You will store and process your data on EBS volumes, so to create an EBS volume you specify the volume size (in Gigabytes) and the availability zone (keep in mind that your initial setup above assumes a certain region). This amount of data storage is static, so, after creating it is very difficult to expand the size. Choose the size wisely!
$ aws_ebs_create Usage: aws_ebs_create [size in GB] [zone] "Description in double quotes"
$ aws_ebs_create 100 us-west-2c "My shiny data" Create volume in us-west-2c that is 100 GB? [Y/n] Y Creating volume ...
You will now see this in your list of AWS resources:
$ awsls ---------------------------------------------------------------------------------------------------------- Volume ID Description Avail. Zone Size User Status Instance ---------------------------------------------------------------------------------------------------------- vol-85cb3210 My shiny data us-west-2c 100GB mike_oregon available --
At this point, we recommend p2 instances for particle picking / ctf estimation (p2.xlarge), 2D classification (p2.16xlarge), and 3D classification/refinement (p2.8xlarge). To start one of these instances with your EBS volume attached:
$ awslaunch --instance=p2.8xlarge --availZone=us-west-2c --volume=vol-85cb3210
Note: If you want to upload data, use p2.8xlarge ($0.90/hr) or c4.xlarge ($0.199/hr).
After running this command, the log in information will be shown on the command line or you can always see it using:
$ awsls AWS EC2 information for user mike_oregon in region us-west-2 ---------------------------------------------------------------------------------------------------- InstanceType Avail. Zone InstanceID Status User Login info ---------------------------------------------------------------------------------------------------- p2.8xlarge us-west-2c i-98sdkfksdf9ssd9 running mike_oregon ssh -X -i /home/michaelc/.aws/mike_oregon.pem [email protected]
To log on, just copy the ssh information into your command line:
$ ssh -X -i /home/michaelc/.aws/mike_oregon.pem [email protected]
And it will log you onto your machine.
Your data will be located in the folder /data/:
To access:
$ cd /data
When you are finished analyzing your data, you can terminate your instance using:
$ awskill Usage: awskill [instance ID or cluster name]
To kill your instance:
$ awskill i-98sdkfksdf9ssd9
Note: If there are any running processes such as a relion GUI or an open terminal, it cannot terminate the instance. Kill / stop these processes and then try again.
The underlying code is written in python and aliased to simple commands: awsls, awslaunch, awskill.
-
awsls
- Lists all instances & volumes assigned to user, where user instances are assigned based upon being tagged with key pair name as the instance Owner.
- Include -i to only show instances that are running
- Include -v to only show EBS volumes
- Include -c to include listings of any clusters created with STARcluster
- Example usage:
$ awsls --------------------------------------------------------------------------------------- ReservedInstanceType Avail. Zone InstanceID Status IP Address User --------------------------------------------------------------------------------------- No instances found ---------------------------------------------------------------------------------------------------------------------------------------- SpotInstanceType Avail. Zone SpotInstanceID SpotStatus InstanceID Status IP Address Price User ---------------------------------------------------------------------------------------------------------------------------------------- m3.medium us-west-2a sir-b6dg94hn closed --- --- --- $0.040 mike_oregon ---------------------------------------------------------------------------------------- Volume ID Avail.

During the course of processing, this workflow will temporarily place data onto S3 and EBS volumes to speed up data processing. This data can be removed by running the command:
$ delete_temp_s3_ebs
This will remove all S3 buckets and EBS volumes that have the naming pattern: rln-aws-tmp.
All buckets and volumes will be removed based upon the number of days specified in your aws_init.sh file, where any bucket or volume older than the specified time will be removed.
