Role overview

• This role installs OpenShift Serverless (backed by KNative) into an OpenShift Cluster. It consists of the following tasks files:

  • Tasks: pre_workload.yml - Sets up an environment for the workload deployment.

    • Debug task will print out: pre_workload Tasks completed successfully.

  • Tasks: workload.yml - Used to deploy OpenShift Serverless

    • This role creates a namespace (project) and deploys the operator. It will then create the KNativeServing object that deploys the controllers etc.

    • Debug task will print out: workload Tasks completed successfully.

  • Tasks: post_workload.yml - Used to configure the workload after deployment

    • This role doesn’t do anything here

Review the defaults variable file

• This file ./defaults/main.yml contains all the variables you need to define to control the deployment of your workload.

• The variable ocp_username is mandatory to assign the workload to the correct OpenShift user.

• A variable silent=True can be passed to suppress debug messages.

Deploy a Workload with the ocp-workload playbook [Mostly for testing]

# a TARGET_HOST is specified in the command line, without using an inventory file
ansible-playbook -i ${TARGET_HOST}, ./configs/ocp-workloads/ocp-workload.yml \
