WHAT

Investigate a scenario where the customer is installing RHOSAK + RHOC on low resource cluster

WHY

Apart from defining the minimum requirements of resources, if one component designates higher priority classes in comparison to another component there may be pod evictions etc that are not expected. We need to study these situations and need to create alerts accordingly.

HOW

Deploy a RHOSAK hybrid cluster then try installing RHOC where the resources are not sufficient or after installing both components try removing a node or two to see how the system behaves and how it affects the service(s). Typically during the OpensShift upgrades the nodes are cordoned for upgrade.

DONE

Include the following where applicable:

• <bulleted list of functional acceptance criteria that need to be completed>
• <call out anything on the documentation side that's needed as a result of this task being completed>
• <any metrics, monitoring dashboards and alerts that need to be created or be updated>
• <SOP creation or updates>

Guidelines

The following steps should be adhered to:

• Required tests should be put in place - unit, integration, manual test cases (if necessary)
• CI and all relevant tests passing
• Changes have been verified by one additional reviewer against:
• each required environment
• each supported upgrade path
• If the changes could have an impact on the clients (either UI or CLI), a JIRA should be created for making the required changes on the client side and acknowledged by one of the client side team members. PR has been merged
