使用卷時無法啟動 nginx 容器（使用 ansible 和 docker-compose）

Question

我正在嘗試使用 ansible 和 docker-compose 從一台機器啟動一個 nginx 容器到另一台機器。

每當我將 nginx.conf 包含到卷中時，都會出現一個我不明白的錯誤。 容器僅創建但未啟動。

機器1

運行劇本的命令： ansible-playbook -v nginx-playbook.yml -l ubuntu_node_1 -u root

我的劇本：

- 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"

這是錯誤：

注意：當我嘗試在 MACHINE-2 上使用具有相同配置的 docker-compose 直接運行 nginx 容器時，它可以工作。 我相信在嘗試從 MACHINE-1 到 MACHINE-2 執行劇本時會發生一些權限問題，但無法弄清楚。
