1930944 - interactive docker-worker tasks don't start the system dbus daemon

Status: RESOLVED FIXED

(Firefox Build System :: Task Configuration, defect, P3)

Description

[Julien Cristau [:jcristau]]

The ubuntu*-test dockerfiles set an entry point for the image:
https://searchfox.org/mozilla-central/rev/55837bbe3e47f9b4fa91ef83a44b53823626f01d/taskcluster/docker/ubuntu1804-test/Dockerfile#83
That causes the dbus system bus to get started before run-task itself, making it available to the task.

When using the "interactive" taskcluster feature to run tasks, however, docker-worker overrides the entrypoint to start its interactive_wrapper_run.sh (https://github.com/taskcluster/taskcluster/blob/930d5517c4c0a11582e01eae74d2b3c1b037bb02/workers/docker-worker/src/task.js#L445-L456); in theory that should run the old entrypoint, but in practice that's not what we're seeing (either due to a bug or a too-old docker-worker or ...).

Not sure this should be assigned to you, Julien, but you are probably best positioned to triage?

Yeah I guess I'll take this. Interactive tasks in general are in dire need of TLC, but since I've got a workaround for this I might go ahead and land it.
