ocp4-abi-script

This repo is designed to deploy a Red Hat OpenShift cluster with ABI method on a BareMetal server.

Prerequisite

• Offline Registry has been configured and its reachable from the localhost

• RHCOS_Cache has been configured and its reachable from the localhost

• In a total disconnected environment the oc-cli and oc-mirror-cli are made available in the ${HOME}/ocp4-abi-script/bin/ of this project before usage, if the existing ones version are out of scope. Be aware, that the verison used in this is 4.12.2 and you should update the binaries to the OCP version you are going to deploy.

• RHEL base Operating System

Quick Start

[midu@GFA2MKUN ]$ git clone https://github.com/midu16/ocp4-abi-script.git
[midu@GFA2MKUN ]$ cd ocp4-abi-script
[midu@GFA2MKUN ocp4-abi-script]$ ls -l
total 24
-rwxrwxr-x 1 midu midu 14523 Mar  8 12:06 abi.sh
-rw-rw-r-- 1 midu midu  2791 Mar  8 12:06 cluster-plan.yaml

The abi.sh-cli help:

[midu@GFA2MKUN ocp4-abi-script]$ ./abi.sh
Some or all of the parameters are empty

Usage: ./abi.sh -a /apps/registry/pull-secret.json -b parameterB -c parameterC
        -a This parameter is requiring the path to the pull-secret.json. Example: /apps/registry/pull-secret.json. Please note, that the pull-secret.json should inlcude the public and also private registry information.
        -b This parameter is requiring the OpenShift Container Platform version to be installed. Example: 4.12.2
        -c This parameter is requiring the cluster-plan.yaml. Example: /apps/registry/cluster-plan.yaml
        -d The use of this parameter its enabling fully disconnected mode. The Offline Registry and RHCOS Cache are assumed completed. Example: True. Default value is set to False

Quick Usage

• The usage in a total disconnected environment:

[midu@GFA2MKUN ocp4-abi-script]$ ./abi.sh -a ./path/to/pull-secret.json -b 4.12.2 -c cluster-plan.yaml -d True

In the above use-case, when the deployment environment its total disconnected, the assumption is that the oc-cli, oc-mirror-cli, Offline Registry and RHCOS Cache server are made available before. In the case of the oc-cli and oc-mirror-cli are made available in the ${HOME}/ocp4-abi-script/.

• The usage in a connected environment:

[midu@GFA2MKUN ocp4-abi-script]$ ./abi.sh -a ./path/to/pull-secret.json -b 4.12.2 -c cluster-plan.yaml -d False

In the above use-case, when the deployment environment its on a connected host, the script will validate the connection to the public RH registry to download the oc-cli, oc-mirror-cli, mirror the OpenShift Container Platform release cluster operator container base images and the RHCOS base image.

In the working directory its required before starting the process to have the pull-secret.json download and add the offline registry information appended to the file in the pull-secret.json.
