Dear all, I have not solved this issue yet. Please, can anyone run the same test and let me know if the fetcher is correctly invoked? The test is really simple, just try to start a dockerized app (see json definition file below) through marathon on a mesos slave running in a docker container started with the option —docker_mesos_image=<mesos slave image>. I would appreciate very much any feedback.
Sample Marathon app:
{
"id": "test-app",
"container": {
"type": "DOCKER",
"docker": {
"image": "libmesos/ubuntu"
}
},
"cpus": 1,
"mem": 512,
"uris": [
"http://www.stat.cmu.edu/~cshalizi/402/lectures/16-glm-practicals/snoqualmie.csv";
],
"cmd": "cd $MESOS_SANDBOX; ls -latr; while sleep 10; do date -u +%T; done"
}
Docker run command to start dockerized mesos slave:
# docker run -d MESOS_HOSTNAME=<SLAVE_IP> -e MESOS_IP=<SLAVE_IP> -e
MESOS_MASTER=zk://<node-1>:2181,<node-2>:2181,<node-3>:2181/mesos -e
MESOS_CONTAINERIZERS=docker,mesos -e MESOS_EXECUTOR_REGISTRATION_TIMEOUT=5mins
-e MESOS_LOG_DIR=/var/log -e MESOS_docker_mesos_image=mesos-slave -v
/sys/fs/cgroup:/sys/fs/cgroup -v /var/run/docker.sock:/var/run/docker.sock -v
/tmp/mesos:/tmp/mesos --name slave --net host --privileged --pid host
mesos-slave
Thank you very much in advance!
Best regards,
Marica
