OSE-pre-install

Summary

In this project, I developed an ansible playbook which preparing OpenShit Nodes and master for installation

The inventory file that used for the OpenShift installation is the same inventory here

Usage

This playbook have to run from the master node.

Few parameters have to be provided when running this playbook:

• Subscription credentials
• Node's ssh credentials (always using root, all the nodes MUST have the same password for root)

Example

ansible-playbook  pre-ocp-install.yaml \
                  -i inventory.txt \
                 --extra-vars "ssh_password=change_me" \ 
                 --extra-vars "[email protected]" \
                 --extra-vars "subscription_password=super_secret_password" \
                 --extra-vars "pool_id=<your_pool_id>"

Note:

Since RHEL system requires subscription configuration, before installing ansible and git I wrote additional script who doing all the dirty work.

To use the RHEL preparation script just execute the following command in your master node

curl -o RHEL_prepare.sh https://raw.githubusercontent.com/shalomnaim1/OSE-pre-install/master/RHEL_prepare.sh

and start it by executing:

sh RHEL_prepare.sh -u <subscription_user> -p <subscription_password> -P <pool_id>

This script take care the following tasks:

• Configure subscription on the master node
• Installing Git and ansible on the master node
• Clone this repo to the master node

Most of the output of the script is redirected into RHEL_prepare.log, which exist in the same folder RHEL_prepare.sh executed from
