Bifrost container deploy broken by dumb-init ENTRYPOINT

[Mark Goddard]

Bifrost was broken by the recent kolla change [1] to use an ENTRYPOINT for dumb-init. The container failed to start because dumb-init was trying to run /sbin/init, which expects to be pid 1.

As seen in kayobe CI, the container keeps restarting:

Affects stable/rocky. Queens patch for dumb-init entrypoint has not yet merged, so that branch is not affected.

    Use dumb-init with --single-child

    We would probably like to forward signals only to the direct child
    which in turn takes care its children and not to all worker child
    processes.
