Docker swarm-manager displays old container information
I am using docker-machine with Google Compute Engine(GCE)
to run a
docker swarm cluster. I created a swarm successfully with 2
(swnd-01 & swnd-02) in the cluster. I created a daemon container
in the swarm-manager environment:
docker run -d ubuntu /bin/bash
docker ps shows the container running on swnd-01. When I tried
executing a command over the container using
docker exec I get the
error that container is not running while
docker ps shows otherwise.
ssh‘ed into swnd-01 via docker-machine to come to know that container
exited as soon as it was created. I tried
docker run command inside the
swnd-01 but it still exits. I don’t understand the behavior.
Any suggestions will be thankfully received.

The reason it exits is that the
/bin/bash command completes and a Docker container only runs as long as its main process (if you run such a container with the
-it flags the process will keep running while the terminal is attached).
As to why the swarm manager thought the container was still running, I’m not sure. I guess there is a short delay while Swarm updates the status of everything.
