We have it now, that is what is talked about in the end of the
I would like to stress that docker is intended to be
process container not system container.
In adeal (aka. Fictional unicorn) containers you
would have a single process. Your start.sh should exec (to
replace the shell) the application ("exec node ." Or "exec java
Many applications does not fit such restrictions.
People end up using things like supervisord (a python script
that manage multiple processes ) but of course it won't work out
of the box. One need to rewrite services into its .ini format.
We have seen many fake systemds that are not 100%
Having real systemd would make dockerizing such apps
a trivial job.
I would love if real systemd that just work. that
fail gracefully for example when it does not have cgroups
mounted it would just ignore cgroups-related directives.
I wish if I just run
docker run -dt fedora-systemd
Without any -v
How far are we from this?
