Description

The proposal to support Beam Python applications with the Flink k8s operator requires the addition of a sidecar container for the Beam SDK worker pool to the Flink task manager pod.

The sidecar container needs to be specified with image, resources and entry point, but generally it is just another container that has access to external resources similar to the task manager container.

Since there isn't anything Beam specific per se, should the CRD offer something like a taskManagerSideCar section that could also be used for other containers the user may wish to run alongside a task manager in the same pod?

Research direction

Start by reading the linked proposal and the operator's CRD and task manager pod configuration. Determine whether a taskManagerSideCar section should support image, resources, and entry point while remaining general-purpose; done means the design is decided and the operator can specify the additional container as required.
