reproduce-script

This is a script to reproduce the problems we're experiencing with OVN-kubernetes on OCP4.8.

We are aware that this does not represent normal use of a cluster.

Requirements

• Be logged in as a user with cluster-admin permissions.
• Have Ansible installed.
• Have pip3 installed. (For installing the Python modules.)
• Have a writable registry configured within the cluster.
• (For the error to occure: ovn-kubernetes SDN.)

Usage

1. cd to the same directory as this file.
2. Install Python requirements:

pip3 install --user -r requirements.txt

3. Install Ansible requirements:

ansible-galaxy collection install -r requirements.yml

4. Run the playbook:

ansible-playbook deploy-script.yml

5. Run the script:

./run.sh

Actions done to your cluster

This playbook and script applies some changes to your cluster.
Changes made by the playbook:

• Creates a ServiceAccount within the openshift namespace. (I had to put it somewhere...)
• Creates a ClusterRoleBinding ("health-check-script-self-provisioner").
• It configures config.ini in the app directory with your default clusterdomain, the API token of the SA and your API URL.

Changes made by the script:

• The script creates a namespace health-check and DELETES it afterwards.
• It deploys an S2I app within that namespace.
