使用 Ansible 在 Amazon linux 2 上安装 docker 和 docker-compose 失败 - 手动成功

问题描述 投票：0回答：1

我有两个运行 Amazon Linux 2 操作系统的 ec2 实例 (amzn2-ami-hvm-2.0.20240610.1-x86_64-gp2)

uname -a
Linux ip-172-31-24-106.eu-central-1.compute.internal 4.14.345-262.561.amzn2.x86_64 #1 SMP Fri May 31 18:15:42 UTC 2024 x86_64 x86_64 x86_64 GNU/Linux

在其中一个上，我手动安装 docker 和 docker-compose，如下所示：


# # # Install docker # # # 

sudo yum update -y 

sudo yum install docker 

sudo service docker start 

sudo usermod -a -G docker ec2-user

docker version

Client:
 Version:           20.10.25




# # # Install docker-compose # # # 

sudo curl -L https://github.com/docker/compose/releases/latest/download/docker-compose-Linux-x86_64 -o /usr/local/bin/docker-compose

sudo chmod +x /usr/local/bin/docker-compose

docker-compose version

Docker Compose version v2.27.1

ls -l /usr/local/bin/docker-compose

-rwxr-xr-x 1 root root 63052874 Jun 17 16:54 /usr/local/bin/docker-compose

这样一切就正常了。

但是，当我尝试通过 Ansible 安装 docker 和 docker-compose 时，出现错误。 这是我应用的剧本：

---
- name: Install python3, docker, docker-compose
  hosts: [docker_server] 
  become: yes
  gather_facts: False 
  tasks:
    - name: Install python3 and docker
      ansible.builtin.yum: 
        use_backend: yum3 
        name:

        dest: /usr/local/bin/docker-compose
        mode: '+x'
      register: docker_compose_result
    - debug: var=docker_compose_result
    - name: Start docker daemon
      ansible.builtin.systemd:

          - docker-compose

  hosts: [docker_server] 
  become: yes
  tasks: 
    - name: Add ec2-user to docker group
      ansible.builtin.user: 
        name: ec2-user
        groups: docker  
        append: yes
    - name: Reconnect to server session
      ansible.builtin.meta: reset_connection


- name: Start docker containers
  hosts: [docker_server] 
  vars_files:
    - project-vars
  tasks:
    - name: Copy docker compose
      ansible.builtin.copy:
        src: /home/tomas/gitlab/ansible-learn-nana/docker-compose.yaml
        dest: /home/ec2-user/docker-compose.yaml
    - name: Start container from compose
      community.docker.docker_compose_v2: 
        project_src: /home/ec2-user

这是我得到的错误：

当我

ssh
进入这台应该由Ansible配置的机器时，这就是我所看到的：

cd /usr/local/bin/  # Directory where curl downloads docker-compose
ls -l
total 24
-rwxr-xr-x 1 root root 212 Jun 17 17:05 distro
-rwxr-xr-x 1 root root 215 Jun 17 17:05 docker-compose
-rwxr-xr-x 1 root root 212 Jun 17 17:05 dotenv
-rwxr-xr-x 1 root root 213 Jun 17 17:05 jsonschema
-rwxr-xr-x 1 root root 233 Jun 17 17:05 normalizer
-rwxr-xr-x 1 root root 216 Jun 17 17:05 wsdump

如果我尝试在这台失败的机器上手动下载 docker-compose，文件大小会有所不同：

sudo curl -L https://github.com/docker/compose/releases/latest/download/docker-compose-Linux-x86_64 -o /usr/local/bin/docker-compose

cd /usr/local/bin/ # Directory where curl downloads docker-compose
ls -l
total 61596
-rwxr-xr-x 1 root root      212 Jun 17 17:05 distro
-rwxr-xr-x 1 root root 63052874 Jun 17 17:08 docker-compose
-rwxr-xr-x 1 root root      212 Jun 17 17:05 dotenv
-rwxr-xr-x 1 root root      213 Jun 17 17:05 jsonschema
-rwxr-xr-x 1 root root      233 Jun 17 17:05 normalizer
-rwxr-xr-x 1 root root      216 Jun 17 17:05 wsdump

所以看来我的playbook在这项任务上失败了：

- name: Install Docker Compose
      get_url:                              
        url: https://github.com/docker/compose/releases/latest/download/docker-compose-Linux-x86_64 
        dest: /usr/local/bin/docker-compose
        mode: '+x'
      register: docker_compose_result
    - debug: var=docker_compose_result

即使调试显示

"status_code": 200

任何关于我可以在哪里查看的建议都将受到高度赞赏。

希望您度过愉快的一天。我遇到了同样的问题。

问题是您正在将community.docker.docker_compose_v2与docker compose版本1一起使用。 我想说的是，我不建议您返回community.docker.docker_compose，因为它已被弃用。

我在 Amazon Linux 上也面临同样的问题，我可以通过两种方式解决。不理想，但这是暂时的：

第一个解决方法：

    - name: Start containers from compose 
  ansible.builtin.command:
    cmd: docker-compose up -d

第二个解决方法：

      become: yes
  vars_files:
    - project-vars
  tasks:
    - name: Copy Docker compose
      copy: 
        src: /root/ansible/Ansible/docker-compose.yaml
        dest: /home/ec2-user  
    - name: Docker login
      docker_login:
        registry_url: https://index.docker.io/v1
        username: ibrahimosama
        password: "{{docker_password}}"
    - name: Start containers from compose 
      community.docker.docker_compose_v2:
        project_src: /home/ec2-user

最终的解决方法是安装 docker compose 版本 2：

    - name: Install docker compose V2 
  hosts: ec2
  become: yes
  tasks:
    - name: Create directory for Docker CLI plugins
      file:
        path: /usr/local/lib/docker/cli-plugins
        state: directory
        mode: '0755'
    - name: Download Docker Compose V2 binary
      get_url:
        url: https://github.com/docker/compose/releases/download/v2.18.0/docker-compose-linux-x86_64
        dest: /usr/local/lib/docker/cli-plugins/docker-compose
        mode: '0755'
    - name: Make Docker Compose binary executable
      file:
        path: /usr/local/lib/docker/cli-plugins/docker-compose
        mode: '0755'
    - name: Verify Docker Compose installation
      command: docker compose version
      register: docker_compose_version
      ignore_errors: yes
    - name: Show Docker Compose version
      debug:
        msg: "{{ docker_compose_version.stdout }}"
      when: docker_compose_version.rc == 0
