Is it possible to show the restart policy of a running Docker container?

Question

When I create containers I'm specifying a restart policy, but this is not shown in docker ps, and it doesn't appear any format string shows this either.

Does anyone know how to see the restart policy of a running container(s)?

Yes, it is possible using docker inspect which is json format and just need to query it.

Here is relevant output of docker inspect for a running container zen_easley. Note to change container name as suitable for your environment.

• docker inspect zen_easley

"HostConfig": {             "Binds": null,             "ContainerIDFile": "",             "LogConfig": {                 "Type": "json-file",                 "Config": {}             },             "NetworkMode": "default",             "PortBindings": {},             "RestartPolicy": {                 "Name": "no",                 "MaximumRetryCount": 0             },             "AutoRemove": true, 

You can just run the following command to get the same and its output.

$ docker inspect -f "{{ .HostConfig.RestartPolicy }}"  zen_easley {no 0} 

If you see RestartPolicy has two properties Name, MaximumRetryCount and no, 0 are the values respectively in the above output

You may also get the individual property value, say Name by using below command, appending .Name to the above command:

docker inspect -f "{{ .HostConfig.RestartPolicy.Name }}"  zen_easley no
