如何使用docker_host_info过滤docker个退出状态的容器？

Question

是否有任何其他 ansible-docker 模块来捕获 VM 上的所有容器，甚至是处于退出状态的容器。

 - name: Get container info
    docker_host_info:
      containers: yes
    register: result

docker_host_info 仅捕获处于 UP 状态的容器。有没有办法捕获或过滤处于退出状态的那些。请帮忙。

Answer 1

您需要使用带有过滤器 status=exited 的 containers_filter 选项。

检查这个 ansible 剧本：

---
- 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 }}"

我的 VM 上几乎没有退出的容器。

[centos@jumphost tmp]$ docker ps -a

[centos@jumphost tmp]$

运行 ansible 剧本：

[centos@jumphost tmp]$ sudo ansible-playbook -c local -i 127.0.0.1 a.yaml 
[WARNING]: Unable to parse /var/tmp/127.0.0.1 as an inventory source
[WARNING]: No inventory was parsed, only implicit localhost is available
[WARNING]: provided hosts list is empty, only localhost is available. Note that the implicit localhost does not match 'all'

[centos@jumphost tmp]$

如您所见，仅列出了退出的容器。

更新：

要同时列出运行和已退出的容器，请使用多个 ansible 任务。

Task 1:
- name: Get exited container info
    |
containers_filters:
        status: "exited"
    |
Task 2
- name: Get running container info
    |
containers_filters:
        status: "running"
