Small project to kickstart my openshift evaluation

OpenShift Kickstarter

I have created this repository to reduce the time necessary to install OpenShift v3 for Demos and PoC's

Files

• ansible_inventory - this file holds the information about your desired environment.
• openshift_prereqs.yml - is a Ansible Playbook to make sure your systems are able to talk to each other and that fulfills the necessary prerequisites.
• openshift_aws and openshift_aws.pub - These are the ssh key files that are used to login from the master to the nodes.
• installer.cfg.yml - is the installer configuration file
• example_hosts - is the example hosts file, that is used to prepare the ansible installation from the master.

Next Steps

Review ansible_inventory and make sure the content matches your environment. In the default case I have set it up in the following way:

[openshift_nodes]
openshift-master.openshift.me
openshift-node1.openshift.me
openshift-node2.openshift.me

[openshift_master]
openshift-master.openshift.me

which means that I will have one master and 2 nodes. Plus I will let the master act as a node as well.

Environment Variables

Make sure to create a file or create the environment variables by hand

export RHN_USER=<your RHN username>
export RHN_PASS=<your RHN Password>
export ANSIBLE_USER=<username used to connect to remote systems>
export ANSIBLE_SUDO=<Whether the user should use sudo>

you can use the env.example file for your convenience to prepare your environment.

mv env.example env
vi env # edit the file and add the appropriate values
source env

to run the installer run the following command:

ansible-playbook -i ./ansible_inventory ./openshift_prereqs.yml
