Question

我正在尝试使用ansible和docker-compose从一台机器到另一台机器来启动nginx容器。

每当我将nginx.conf包含到卷中时，就会出现我不理解的错误。 仅创建容器，而不启动容器。

MACHINE-1

运行剧本的命令：ansible-playbook -v nginx-playbook.yml -l ubuntu_node_1 -u root

我的剧本：

- name: nginx-docker_compose
  hosts: all
  gather_facts: yes
  become: yes
  tasks:
    - community.general.docker_compose:
        project_name: nginx
        definition:
          version: '2'
          services:
            web:
              image: nginx:latest
              volumes:
                - ./vars/nginx.conf:/etc/nginx/nginx.conf:ro
              ports:
                - "8080:80"

这是错误：

Using /etc/ansible/ansible.cfg as config file

注意：当我尝试在MACHINE-2上使用相同配置直接使用docker-compose直接运行nginx容器时，它可以工作。我相信在尝试从MACHINE-1到MACHINE-2执行剧本时会发生一些权限问题，但无法弄清楚。

现在可以使用。感谢@mdaniel。

我更改的内容：

我将整个目录写在了剧本中-/home/some_more_folders/nginx.conf
，并在目标计算机上复制了具有相同目录结构的相同文件。

仍然有待解决的问题：

您知道为什么有必要将任何文件复制到目标计算机（例如nginx.conf）吗？
如何手动执行将配置文件复制到docker-compose的目标计算机的手动过程？

使用卷时无法启动nginx容器（使用ansible和docker-compose）
