Demo Environment Ansible Scripts

These are the scripts used to stand up your own environment running the demo from the 2015 JBoss Middleware Keynote at Red Hat Summit.

Prerequisites

• An AWS account with permissions to do the following:

  • Create and modify a VPC (A VPC is created for each cluster-id)
  • Create and modify Security Groups (2 security groups are created for each cluster-id, one for masters and one for nodes)
  • Create and modify route53 entries (Route 53 entries are added to the hosted zone specified by r53-zone for each ec2 instance created as well as a wildcard dns entry for router)
  • Create and modify EC2 instances

• AWS credentials may be specified either through the AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY env variables or using any of the environment variables/configs supported by boto

• A pre-created route53 public hosted zone

• A pre-created ec2 keypair

  • You will need to specify the name of this keypair when running the environment creation script
  • You will also need to add the private key to your ssh agent: ssh-add <path to key file>

• Amazon AMIs

  AMI	Amazon Region
  ami-2051294a	us-east-1 (default)
  ami-d1315fb1	us-west-1
  ami-775e4f16	us-west-2

  For other regions: Search the AWS Console, i.e. EC2 -> AMIs -> "Public images" - RHEL-7.2_HVM_GA-20151112-x86_64-1-Hourly2-GP2

Requirements

• Ansible version 1.9.1 or greater

• Click version 3.0 or greater

  • Available in Fedora and EPEL channels as python-click

• The master branch of openshift/openshift-ansible is expected to be a sibling repo to the demo-ansible repo

  git clone https://github.com/2015-Middleware-Keynote/demo-ansible.git
  git clone https://github.com/openshift/openshift-ansible.git
  

Standing up a new Environment

List the options for run.py:

cd demo-ansible
./run.py --help

Stand up an environment using the defaults. run.py will prompt for Rhsm user, Rhsm password and route53 hosted zone

./run.py

Stand up an environment without being prompted for confirmation and overriding the cluster id, and keypair:

./run.py --no-confirm --cluster-id my_cluster --keypair my_keypair \
--r53-zone my.hosted.domain --rhsm-user my_redhat_user --rhsm-pass my_redhat_pass

After the run has completed the openshift web console will be available at https://openshift.<cluster id>.<r53 zone> and routes created for applications will default to <app name>.<project name>.<cluster id>.<r53 zone>

Environment Information

• Accessing your environment shell (Default user is openshift not ec2-user)

ssh -i my_keypair.pem openshift@<ec2_host_public_dns>
