Surya was referring to the second document in this thread which I sent out:
https://github.com/jenkinsci/jep/tree/master/jep/301
I understand the "bad practice" argument against this approach but I haven't
yet seen a counter-proposal which accomplishes what jenkins/evergreen needs to
accomplish, without using supervisord in the "basic" container case, or a
Kubernetes-like thing in the "advanced" case. I'm personally comfortable with
being less dogmatic about what goes into the container, understanding that
there's a future on the horizon filled with Kubernetes :)
As to the concern about the image mutability, the evergreen-client would only
be effectively changing content in the mapped `/var/jenkins_home` which must by
the very nature of Jenkins be mutable. I'll update JEP-301 to make that more
explicit.
Thanks for taking a look-see.
