maven - 使用 ansible playbook 在 docker 容器内运行 mvn clean install

Question

我正在尝试在 docker 容器内运行 mvn clean install 命令。但是似乎什么都没有发生，因为我已将容器映射到一个卷并且没有创建目标文件夹。这是剧本。抱歉，如果这是一个愚蠢的问题，但我现在已经被困在这里一段时间了。

---
- name: Building project
  hosts: all
  become: true
  become_user: root
  tasks:
     - name: install docker mvn
       docker_container:
          name: maven_build_direct
          image: maven
          volumes:
            - /home/user/Desktop/Training/docker/maven_task/happy/GsaJavaExample/:/proj
          command: cd /proj
          command: mvn clean install

我还尝试从 docker-container 模块外部运行命令，但由于容器已经停止，因此会出错。像这样的东西

     - name: copy content in container to some other folder
       command: docker exec -i maven_build_direct bash -c 'echo "Hello1"; echo "Hello2"'

上面的错误是

fatal: [localhost]: FAILED! => {"changed": true, "cmd": ["docker", "exec", "-i", "maven_build_direct", "bash", "-c", "echo \"Hello1\"; echo \"Hello2\""], "delta": "0:00:00.212534", "end": "2018-08-26 17:07:06.995110", "msg": "non-zero return code", "rc": 126, "start": "2018-08-26 17:07:06.782576", "stderr": "", "stderr_lines": [], "stdout": "OCI runtime exec failed: exec failed: cannot exec a container that has stopped: unknown", "stdout_lines": ["OCI runtime exec failed: exec failed: cannot exec a container that has stopped: unknown"]}

正如评论中所指出的，第一个问题是您指定了多个命令属性，这是行不通的。正确的方法是这样设置 workdir 属性:

      ...
      volumes:
        - /home/user/Desktop/Training/docker/maven_task/happy/GsaJavaExample/:/proj
      working_dir: /proj
      command: mvn clean install
      ...
