Kevin Klues commented on MESOS-6540: ------------------------------------ This is what we talked about at lunch yesterday so we can handle entering the proper mount namespace for tasks launched via the command executor. > Pass the forked pid from `containerizer launch` to the agent and checkpoint > it. > ------------------------------------------------------------------------------- > > Key: MESOS-6540 > URL: https://issues.apache.org/jira/browse/MESOS-6540 > Project: Mesos > Issue Type: Task > Reporter: Kevin Klues > Assignee: Kevin Klues > Labels: debugging, mesosphere > > Right now the agent only knows about the pid of the "init" process forked by > {{launcher->fork()}}. However, in order to properly enter the namespaces of a > task for a nested container, we actually need the pid of the process that > gets launched by the {{containerizer launch}} binary. > Using this pid, isolators can properly enter the namespaces of the actual > *task* or *executor* launched by the {{containerizer launch}} binary instead > of just the namespaces of the "init" process (which may be different). > This will involve opening a domain socket with the {{containerizer launch}} > binary and passing the translated pid from the forked process back to the > agent. We can chieve this by opening the socket on the agent and passing the > path to it using {{launchFlags}}. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
