Justin Pinkul commented on MESOS-6143: -------------------------------------- My {{resolv.conf}} is still empty when using the alpine image. I don't understand how that test would pass since {{resolv.conf}} is only modified by the {{network/cni}} isolator which is not enabled in this test. > resolv.conf is not copied when using the Mesos containerizer with a Docker > image > -------------------------------------------------------------------------------- > > Key: MESOS-6143 > URL: https://issues.apache.org/jira/browse/MESOS-6143 > Project: Mesos > Issue Type: Bug > Components: containerization, isolation > Affects Versions: 1.0.0 > Environment: OS: Debian Jessie > Mesos version: 1.0.0 > Reporter: Justin Pinkul > Assignee: Avinash Sridharan > Fix For: 1.1.0 > > > When using the Mesos containierizer, host networking and a Docker image > {{resolv.conf}} is not copied from the host. The only piece of Mesos code > that copies these file is currently in the {{network/cni}} isolator so I > tried turning this on, by setting > {{isolation=network/cni,namespaces/pid,docker/runtime,cgroups/devices,gpu/nvidia,cgroups/cpu,disk/du,filesystem/linux}}, > but the issue still remained. I suspect this might be related to not setting > {{network_cni_config_dir}} and {{network_cni_plugins_dir}} but it seems > incorrect that these flags would be required to use host networking. > Here is how I am able to reproduce this issue: > {code} > mesos-execute --master=mesosmaster1:5050 \ > --name=dns-test \ > --docker_image=my-docker-image:1.1.3 \ > --command="bash -c 'ping google.com; while ((1)); do date; > sleep 10; done'" > # Find the PID of mesos-executor's child process and enter it > nsenter -m -u -i -n -p -r -w -t $PID > # This file will be empty > cat /etc/resolv.conf > {code} > {code:title=Mesos agent log} > I0908 17:39:24.599149 181564 slave.cpp:1688] Launching task dns-test for > framework 51831498-0902-4ae9-a1ff-4396f8b8d823-0006 > I0908 17:39:24.599567 181564 paths.cpp:528] Trying to chown > '/mnt/01/mesos_work/slaves/67025326-9dfd-4cbb-a008-454a40bce2f5-S2/frameworks/51831498-0902-4ae9-a1ff-4396f8b8d823-0006/executors/dns-test/runs/52bdce71-04b0-4440-bb71-cb826f0635c6' > to user 'root' > I0908 17:39:24.603970 181564 slave.cpp:5748] Launching executor dns-test of > framework 51831498-0902-4ae9-a1ff-4396f8b8d823-0006 with resources > cpus(*):0.1; mem(*):32 in work directory > '/mnt/01/mesos_work/slaves/67025326-9dfd-4cbb-a008-454a40bce2f5-S2/frameworks/51831498-0902-4ae9-a1ff-4396f8b8d823-0006/executors/dns-test/runs/52bdce71-04b0-4440-bb71-cb826f0635c6' > I0908 17:39:24.604178 181564 slave.cpp:1914] Queuing task 'dns-test' for > executor 'dns-test' of framework 51831498-0902-4ae9-a1ff-4396f8b8d823-0006 > I0908 17:39:24.604284 181571 docker.cpp:1020] Skipping non-docker container > I0908 17:39:24.604532 181578 containerizer.cpp:781] Starting container > '52bdce71-04b0-4440-bb71-cb826f0635c6' for executor 'dns-test' of framework > '51831498-0902-4ae9-a1ff-4396f8b8d823-0006' > I0908 17:39:24.606972 181571 provisioner.cpp:294] Provisioning image rootfs > '/mnt/01/mesos_work/provisioner/containers/52bdce71-04b0-4440-bb71-cb826f0635c6/backends/copy/rootfses/db97ba50-c9f0-45e7-8a39-871e4038abf9' > for container 52bdce71-04b0-4440-bb71-cb826f0635c6 > I0908 17:39:30.037472 181564 cpushare.cpp:389] Updated 'cpu.shares' to 102 > (cpus 0.1) for container 52bdce71-04b0-4440-bb71-cb826f0635c6 > I0908 17:39:30.038415 181560 linux_launcher.cpp:281] Cloning child process > with flags = CLONE_NEWNS | CLONE_NEWPID > I0908 17:39:30.040742 181560 systemd.cpp:96] Assigned child process '190563' > to 'mesos_executors.slice' > I0908 17:39:30.161613 181576 slave.cpp:2902] Got registration for executor > 'dns-test' of framework 51831498-0902-4ae9-a1ff-4396f8b8d823-0006 from > executor(1)@10.191.4.65:43707 > I0908 17:39:30.162148 181563 disk.cpp:171] Updating the disk resources for > container 52bdce71-04b0-4440-bb71-cb826f0635c6 to cpus(*):0.1; mem(*):32; > gpus(*):2 > I0908 17:39:30.162648 181566 cpushare.cpp:389] Updated 'cpu.shares' to 102 > (cpus 0.1) for container 52bdce71-04b0-4440-bb71-cb826f0635c6 > I0908 17:39:30.162822 181574 slave.cpp:2079] Sending queued task 'dns-test' > to executor 'dns-test' of framework 51831498-0902-4ae9-a1ff-4396f8b8d823-0006 > at executor(1)@10.191.4.65:43707 > I0908 17:39:30.168383 181570 slave.cpp:3285] Handling status update > TASK_RUNNING (UUID: 319e0235-01b9-42ce-a2f8-ed9fc33de150) for task dns-test > of framework 51831498-0902-4ae9-a1ff-4396f8b8d823-0006 from > executor(1)@10.191.4.65:43707 > I0908 17:39:30.169019 181577 status_update_manager.cpp:320] Received status > update TASK_RUNNING (UUID: 319e0235-01b9-42ce-a2f8-ed9fc33de150) for task > dns-test of framework 51831498-0902-4ae9-a1ff-4396f8b8d823-0006 > I0908 17:39:30.169173 181576 slave.cpp:3678] Forwarding the update > TASK_RUNNING (UUID: 319e0235-01b9-42ce-a2f8-ed9fc33de150) for task dns-test > of framework 51831498-0902-4ae9-a1ff-4396f8b8d823-0006 to > master@10.191.248.194:5050 > I0908 17:39:30.169242 181576 slave.cpp:3588] Sending acknowledgement for > status update TASK_RUNNING (UUID: 319e0235-01b9-42ce-a2f8-ed9fc33de150) for > task dns-test of framework 51831498-0902-4ae9-a1ff-4396f8b8d823-0006 to > executor(1)@10.191.4.65:43707 > I0908 17:39:30.171314 181565 status_update_manager.cpp:392] Received status > update acknowledgement (UUID: 319e0235-01b9-42ce-a2f8-ed9fc33de150) for task > dns-test of framework 51831498-0902-4ae9-a1ff-4396f8b8d823-0006 > {code} -- This message was sent by Atlassian JIRA (v6.3.4#6332)
