MCK 1.3.0 Release Notes

Bug Fixes

• This change fixes the current complex and difficult-to-maintain architecture for stateful set containers, which relies on an "agent matrix" to map operator and agent versions which led to a sheer amount of images.
• We solve this by shifting to a 3-container setup. This new design eliminates the need for the operator-version/agent-version matrix by adding one additional container containing all required binaries. This architecture maps to what we already do with the mongodb-database container.
• Fixed an issue where the readiness probe reported the node as ready even when its authentication mechanism was not in sync with the other nodes, potentially causing premature restarts.

Other Changes

• Optional permissions for PersistentVolumeClaim moved to a separate role. When managing the operator with Helm it is possible to disable permissions for PersistentVolumeClaim resources by setting operator.enablePVCResize value to false (true by default). When enabled, previously these permissions were part of the primary operator role. With this change, permissions have a separate role.
• subresourceEnabled Helm value was removed. This setting used to be true by default and made it possible to exclude subresource permissions from the operator role by specifying false as the value. We are removing this configuration option, making the operator roles always have subresource permissions. This setting was introduced as a temporary solution for this OpenShift issue. The issue has since been resolved and the setting is no longer needed.
