AWS Setup Instructions

Get AWS API credentials

1. AWS credentials documentation

Create a credentials file

1. Create a credentials file (eg ~/.aws_creds) that looks something like this (variables must have have these exact names). export AWS_ACCESS_KEY_ID='AKIASTUFF' export AWS_SECRET_ACCESS_KEY='STUFF'
2. source this file source ~/.aws_creds Note: You must source this file in each shell that you want to run cloud.rb

(Optional) Setup your $HOME/.ssh/config file

In case of a cluster creation, or any other case where you don't know the machine hostname in advance, you can use '.ssh/config' to setup a private key file to allow ansible to connect to the created hosts.

To do so, add the the following entry to your $HOME/.ssh/config file and make it point to the private key file which allows you to login on AWS. ''' Host *.compute-1.amazonaws.com PrivateKey $HOME/.ssh/my_private_key.pem '''

Alternatively, you can configure your ssh-agent to hold the credentials to connect to your AWS instances.

(Optional) Choose where the cluster will be launched

By default, a cluster is launched with the following configuration:

• Instance type: m3.large
• AMI: ami-307b3658
• Region: us-east-1
• Keypair name: libra
• Security group: public

If needed, these values can be changed by setting environment variables on your system.

• export ec2_instance_type='m3.large'
• export ec2_ami='ami-307b3658'
• export ec2_region='us-east-1'
• export ec2_keypair='libra'
• export ec2_security_group='public'

Install Dependencies

1. Ansible requires python-boto for aws operations: RHEL/CentOS/Fedora yum install -y ansible python-boto OSX: pip install -U boto

Test The Setup

1. cd openshift-ansible
2. Try to list all instances (Passing an empty string as the cluster_id argument will result in all ec2 instances being listed) bin/cluster list aws ''

Creating a cluster

1. To create a cluster with one master and two nodes bin/cluster create aws <cluster-id>

Updating a cluster

1. To update the cluster bin/cluster update aws <cluster-id>

Terminating a cluster

1. To terminate the cluster bin/cluster terminate aws <cluster-id>
