[jira] [Commented] (MESOS-7141) Support hook scripts to customize actions for container's lifecycle

["Tobias Müller (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/MESOS-7141?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15964290#comment-15964290 ] 

Tobias Müller commented on MESOS-7141:
--------------------------------------

I think having a "Prestop" stage would be useful as well. For example it could be used to enable deregister mechanisms. For example GitLab CI Runners could then deregister properly with the main GitLab instance when the GitLab CI Runner instances are stopped.

> Inspired by [hooks | https://github.com/opencontainers/runtime-spec/blob/master/config.md#hooks] in [OCI's runtime spec | https://github.com/opencontainers/runtime-spec], it would be great to have scripts hooked into the lifecycle of containers.
> The OCI doc has specified 3 stages for hooking:
> * Prestart
> * Poststart
> * Poststop
> We can consider having the 3 stages to start with.
