how to get docker container id?
Hi,
how can we get the container id when executing a TaskInfo with a Docker
ContainerInfo ?
Mesos execute a Docker container with name mesos-xxx but how can we get
this identifier ?
I set in my TaskInfo a unique id in Task Id, but itis not used as Docker
identifier.
I need it to query cAdvisor, running on my nodes.
Thanks
Olivier

Hi Oliver,
With latest master and next 0.23 release we've added docker inspect output in the first task running status update data field.
Therefore from the scheduler you can read and parse as json, and find all the information you need about the container including name and id.

Thanks, I could get it, but it would be nice to get the information in
update message rather than needing to trigger the nodes (with
information for all tasks).

You can query the slave's state.json to get the container ID.
See the previous thread:
