Exclude stopped injected sidecars from TaskRun status
Browse files Browse the repository at this point in the history
fixes #7640

In #5565, we started stopping injected sidecars with `nop` in the same way we stop explicitly defined sidecar containers. `MakeTaskRunStatus` was updated to only include explicitly defined sidecars in the `TaskRun` status, rather than just any container in the `TaskRun` pod that doesn't start with `step-`, so while the pod is running, the injected sidecar doesn't show up in the status. However, once the pod has completed and the sidecars are stopped, if the `TaskRun`'s spec contains a sidecar, `updateStoppedSidecarStatus` will be called, and that function's logic for what containers to include in `TaskRun.Status.Sidecars` is still including everything but `step-`-prefixed containers. That should be updated to behave in the same way as `MakeTaskRunStatus`.
