Stopping a footloose container leaves the system in hard to recover state

[Felipe Fernández]

Context

I'm using Footloose as the base infrastructure for running platform tests through this Gradle plugin. That is supposed to run through automated testing being on CI or locally. As such, infra failures are expected and cleanup automation desirable.

Expected Behavior

If a docker container spin up by Footlose gets destroyed, not through Footloose, the tool should be able to easily recover from this situation on the next runs.

Current Behavior

After the crash, running another footloose create doesn't actually do nothing as the state of container is not reflected.

Steps to Reproduce

footloose create -c config.yaml
INFO[0000] Creating SSH key: cluster-key ...
INFO[0000] Image: quay.io/footloose/ubuntu16.04 present locally
INFO[0000] Creating machine: cluster-node0 ...

footloose show -c config.yaml
NAME            HOSTNAME   PORTS                             IP           IMAGE                           CMD          STATE
cluster-node0   node0      22->58518,8180->8180,8888->8888   172.17.0.2   quay.io/footloose/ubuntu16.04   /sbin/init   Running

Emulate a non managed by Footloose crash with this:

docker stop cluster-node0
cluster-node0

footloose show -c config.yaml
NAME            HOSTNAME   PORTS   IP   IMAGE                           CMD          STATE
cluster-node0   node0                   quay.io/footloose/ubuntu16.04   /sbin/init   Stopped

As the state is Stopped, you might expect that running create again would work. However:

footloose create -c config.yaml
INFO[0000] Image: quay.io/footloose/ubuntu16.04 present locally
INFO[0000] Creating machine: cluster-node0 ...
INFO[0000] Machine cluster-node0 is already created...

docker ps
CONTAINER ID   IMAGE     COMMAND   CREATED   STATUS    PORTS     NAMES

Interesting enough if now I delete it from Footloose I get this:

footloose delete -c config.yaml
INFO[0000] Deleting machine: cluster-node0 ...

footloose show -c config.yaml
NAME            HOSTNAME   PORTS                         IP   IMAGE                           CMD   STATE
cluster-node0   node0      0->22,8888->8888,8180->8180        quay.io/footloose/ubuntu16.04         Stopped

So the STATE is the same Stopped but now the ports are displayed, that's somehow confusing.

Notes

Orthogonal to this, but motivated by this scenario, I've opened this other issue.
