Is there any other ansible-docker module to capture all the containers on the VM even the ones in exited status.
- name: Get container info
docker_host_info:
containers: yes
register: result
docker_host_info captures the containers only in UP status. Is there a way to capture or filter the ones in exited status. Kindly help.
You need to make use of containers_filter option with a filter status=exited
.
Check this ansible playbook:
---
- name: First playbook
hosts: 127.0.0.1
gather_facts: true
become: true
tasks:
- name: Get container info
docker_host_info:
containers: yes
containers_filters:
status: "exited"
register: result
- debug:
msg: "Exited container list : {{ item['Names'] }}"
loop: "{{ result.containers }}"
I have few exited container on my VM.
[centos@jumphost tmp]$ docker ps -a

Run the ansible playbook:
[centos@jumphost tmp]$ sudo ansible-playbook -c local -i 127.0.0.1 a.yaml

As you can see only the exited containers are getting listed.
Update:
To list both running and exited container use multiple ansible task.
Task 1:
- name: Get exited container info
|
containers_filters:
status: "exited"
|
Task 2
- name: Get running container info
|
containers_filters:
status: "running"
