Missing bind mounts for mesos-slave about docker-containers HOT 7 CLOSED

Good catch. Do you bind mount /usr/bin/docker or /usr/local/bin/docker? If you're using the official docker-engine package, it's /usr/bin/docker. Can you please verify? Thanks.

from docker-containers.

In more detail, on Ubuntu 14.04, the following should work:

docker run -d --net=host --privileged \
  -e MESOS_PORT=5051 \
  -e MESOS_MASTER=zk://127.0.0.1:2181/mesos \
  -e MESOS_SWITCH_USER=0 \
  -e MESOS_CONTAINERIZERS=docker,mesos \
  -e MESOS_LOG_DIR=/var/log/mesos \
  -e MESOS_WORK_DIR=/var/tmp/mesos \
  -v "$(pwd)/log/mesos:/var/log/mesos" \
  -v "$(pwd)/tmp/mesos:/var/tmp/mesos" \
  -v /var/run/docker.sock:/var/run/docker.sock \
  -v /cgroup:/cgroup \
  -v /sys:/sys \
  -v "$(which docker):/usr/local/bin/docker" \
  -v /lib/x86_64-linux-gnu/libsystemd-journal.so.0:/lib/x86_64-linux-gnu/libsystemd-journal.so.0 \
  -v /usr/lib/x86_64-linux-gnu/libapparmor.so.1:/usr/lib/x86_64-linux-gnu/libapparmor.so.1 \
  mesosphere/mesos-slave:0.28.0-2.0.16.ubuntu1404

$(pwd) included from the original snippet (NB: I prefer to bind mount a specific folder on the system instead of that).

I've tried to add the library binds, but it still doesn't work. This is the log from docker:

Thanks @isavcic ! I am using the official one. After removing the local part it works. This is the snippet I used:

docker run -d --net=host --privileged
-e MESOS_PORT=5051
-e MESOS_MASTER=zk://127.0.0.1:2181/mesos
-e MESOS_SWITCH_USER=0
-e MESOS_CONTAINERIZERS=docker,mesos
-e MESOS_LOG_DIR=/var/log/mesos
-e MESOS_WORK_DIR=/var/tmp/mesos
-v "$(pwd)/log/mesos:/var/log/mesos"
-v "$(pwd)/tmp/mesos:/var/tmp/mesos"

For docker version 1.11.1 you also need the file /usr/lib/x86_64-linux-gnu/libltdl.so.7

Would it be enough to document the instructions for docker run for launching these Images?

from docker-containers.

This issue is the same problem with #17 . The absence of docker client in the container image seems to be the root cause of these issues. Hence marking it as a duplicate of #17 and closing this. Lets try to figure out if bundling a docker client with the image is an option.
