+ AlexR, haosdent For posterity, the root cause of this problem is that when agent is running inside a docker container and `--docker_mesos_image` flag is specified, the pid namespace of the executor container (which initiate the health check) is different than the root pid namespace. Therefore, getting the network namespace handle using `/proc/<pid>/ns/net` does not work because the 'pid' here is in the root pid namespace (reported by docker daemon).
Alex and haosdent, I think we should fix this issue. As suggested above, we can launch the executor container with --pid=host if `--docker_mesos_image` is specified. - Jie On Wed, Mar 29, 2017 at 3:56 AM, tommy xiao <[email protected]> wrote: > it resolved by add --pid=host. thanks for community guys supports. thanks > a lot. > > 2017-03-29 9:52 GMT+08:00 tommy xiao <[email protected]>: > >> My Environment is specified: >> >> mesos 1.2 in docker containerized. >> >> send a sample nginx docker container with mesos native health check. >> >> then get sandbox core dump. >> >> i have digg into more information for your reference: >> >> in mesos slave container, i can only see task container pid. but i can't >> found process nginx pid. >> >> but in host console, i can found the nginx pid. so how can i get the pid >> in container? >> >> >> >> >> 2017-03-28 13:49 GMT+08:00 tommy xiao <[email protected]>: >> >>> https://issues.apache.org/jira/browse/MESOS-6184 >>> >>> anyone give some hint? >>> >>> ``` >>> >>> I0328 11:48:12.922181 48 exec.cpp:162] Version: 1.2.0 >>> I0328 11:48:12.929252 54 exec.cpp:237] Executor registered on agent >>> a29dc3a5-3e3f-4058-8ab4-dd7de2ae58d1-S4 >>> I0328 11:48:12.931640 54 docker.cpp:850] Running docker -H >>> unix:///var/run/docker.sock run --cpu-shares 10 --memory 33554432 >>> --env-file /tmp/gvqGyb -v /data/mesos/slaves/a29dc3a5-3e >>> 3f-4058-8ab4-dd7de2ae58d1-S4/frameworks/d7ef5d2b-f924-42d9-a >>> 274-c020afba6bce-0000/executors/0-hc-xychu-datamanmesos-2f3b >>> 47f9ffc048539c7b22baa6c32d8f/runs/458189b8-2ff4-4337-ad3a-67321e96f5cb:/mnt/mesos/sandbox >>> --net bridge --label=USER_NAME=xychu --label=GROUP_NAME=groupautotest >>> --label=APP_ID=hc --label=VCLUSTER=clusterautotest --label=USER=xychu >>> --label=CLUSTER=datamanmesos --label=SLOT=0 --label=APP=hc -p 31000:80/tcp >>> --name >>> mesos-a29dc3a5-3e3f-4058-8ab4-dd7de2ae58d1-S4.458189b8-2ff4-4337-ad3a-67321e96f5cb >>> nginx >>> I0328 11:48:16.145714 53 health_checker.cpp:196] Ignoring failure as >>> health check still in grace period >>> W0328 11:48:26.289958 49 health_checker.cpp:202] Health check failed 1 >>> times consecutively: HTTP health check failed: curl returned terminated >>> with signal Aborted (core dumped): ABORT: (../../../3rdparty/libprocess/ >>> include/process/posix/subprocess.hpp:190): Failed to execute >>> Subprocess::ChildHook: Failed to enter the net namespace of pid 18596: Pid >>> 18596 does not exist >>> >>> - >>> - >>> - Aborted at 1490672906 (unix time) try "date -d @1490672906" >>> if you are using GNU date *** >>> PC: @ 0x7f26bfb485f7 __GI_raise >>> - SIGABRT (@0x4a) received by PID 74 (TID 0x7f26ba152700) from >>> PID 74;
