Im working on a little Ansible project in which I'm using Docker Containers.
I'll keep my question short:
I want to get the state of a running Dockercontainer!
What I mean by that is, that i want to get the current state of the container, that Docker shows you by using the "docker ps" command.
Examples would be:
I want to get one of those results from a specific container. But without using the Command or the Shell module!

As of Ansible 2.8 you can use the docker_container_info
, which essentially returns the input from docker inspect <container>
:
- name: Get infos on container
docker_container_info:
name: my_container
register: result
- name: Does container exist?
debug:
msg: "The container {{ 'exists' if result.exists else 'does not exist' }}"
- name: Print the status of the container
debug:
msg: "The container status is {{ result.container['State']['Status'] }}"
when: result.exists
With my Docker version, State
contains this:
"State": {
"Status": "running",
"Running": true,
"Paused": false,
"Restarting": false,
"OOMKilled": false,
"Dead": false,
"Pid": 8235,
"ExitCode": 0,
"Error": "",
"StartedAt": "2019-01-25T14:10:08.3206714Z",
"FinishedAt": "0001-01-01T00:00:00Z"
}
