使用ansible docker_容器模块获取容器的命令输出

我想使用ansible生成XDB配置文件。 其作用与下面的docker命令相同

docker run--rm influxdb influxd config>/opt/influxdb/config/influxdb.conf

我在我的剧本上创建了一个任务，如下所示

  - name: generate influxdb config using temporary container
    docker_container:
      name: influxdb_conf
      state: present
      image: influxdb:1.4
      command: influxd config > /tmp/influxdb.conf
      volumes:
        - "/opt/influxdb/config:/tmp"

- name: generate influxdb config using temporary container
  docker_container:
    name: influxdb_conf
    state: present
    image: influxdb:1.4
    command: influxd config > /tmp/influxdb.conf
    volumes:
      - "/opt/influxdb/config:/tmp"
  register: docker

- name: display logs
  debug:
    msg:  "{{ docker.ansible_facts.docker_container.Output }}"

当我检查输出路径

/opt/influxdb/config

时，它是空的。

如何获取

influxd config

输出？

您可以执行

/bin/sh

作为命令，也可以使用

detach

和

cleanup

：

  - name: generate influxdb config using temporary container
    docker_container:
      name: influxdb_conf
      state: started
      image: influxdb:1.4
      command: "/bin/sh -c 'influxd config > /tmp/influxdb.conf'"
      detach: no
      interactive: yes
      tty: yes
      recreate: yes
      cleanup: yes
      volumes:
        - /opt/influxdb/config:/tmp

您可以注册模块并使用ansible_facts在下一个任务中获取日志，如下所示

  - name: generate influxdb config using temporary container
    docker_container:
      name: influxdb_conf
      state: present
      image: influxdb:1.4
      command: influxd config > /tmp/influxdb.conf
      volumes:
        - "/opt/influxdb/config:/tmp"

- name: generate influxdb config using temporary container
  docker_container:
    name: influxdb_conf
    state: present
    image: influxdb:1.4
    command: influxd config > /tmp/influxdb.conf
    volumes:
      - "/opt/influxdb/config:/tmp"
  register: docker

- name: display logs
  debug:
    msg:  "{{ docker.ansible_facts.docker_container.Output }}"

我还需要更改

状态：已启动
