-------------------------------------
Summary: Capture and report docker issues as part of mesos-master
logs.
Key: MESOS-2790
URL: https://issues.apache.org/jira/browse/MESOS-2790
Project: Mesos
Issue Type: Improvement
Components: docker
Affects Versions: 0.22.1
Environment: CentOS 7 x86-84
Reporter: Casey Sybrandy
I just ran into an issue today where docker ran into an error where it couldn't
update it's iptables chain. (It was missing for some reason.) It took a while
to debug the problem because as far as mesos was concerned, there were no
errors. Executing the container simply failed.
To try to make it easier to know what's going on, is it possible for the mesos
slaves to capture any docker errors and report them as part of the mesos master
log? Even better would be if it could report the error via the UI. At a bare
minimum, and only if you can't nicely capture the docker error, report that a
docker error has occurred and which machine it occurred on.
