使用ansible在RHEL VM上安装Docker

我想使用Ansible从远程RHEL VM上的二进制文件安装Docker CE。我遵循了中提到的步骤 guide

我看到的调试输出是:

TASK [Debug] *********************************************************************************************************************************************************************************************************************************

    "stdout_lines": [], 
    "warnings": [
        "Consider using 'become', 'become_method', and 'become_user' rather than running sudo"

} }

这是我的Ansible剧本:

---
 - hosts: remotes
   become: yes
   tasks:
    - name: Fetch docker version
      shell: docker version 2>&1 | grep Version | awk '{print $2}'
      register: docker_version 

    - name: Check if docker is installed, download binary otherwise
      command: curl -O https://download.docker.com/linux/static/stable/x86_64/docker-17.12.0-ce.tgz
      when: docker_version.stdout == ''

    - name: Extract binary
      unarchive: 
        src: /root/docker-17.12.0-ce.tgz
        dest: /root/
        remote_src: yes
      when: docker_version.stdout == ''

    - name: start docker
      shell: sudo /root/docker/dockerd &
      register: tmp

    - name: Debug
      debug: 
        var: tmp

另一方面,我登录到远程VM并运行

ls -al docker

只是花了点时间给你看看我能不能弄明白。下面的剧本是我为你准备的,很有用。虽然它与您的原始代码有点不同。但我只是想和你分享一下,看看这对你是否有帮助。

- hosts: test_nodes
  vars:
    _docker_version: 17.12.0
  tasks:
    - group:
        name: docker
        state: present
      become: true

    - name: Setting HOME Directory Path
      set_fact:
        _home: "{{ ansible_env['HOME'] }}"

    - name: Fetch docker version
      shell: docker version 2>&1 | grep Version | awk '{print $2}'
      register: docker_version

    - name: Check if docker is installed, download binary otherwise
      get_url:
        url: "https://download.docker.com/linux/static/stable/x86_64/docker-{{ _docker_version }}-ce.tgz"
        dest: "{{ _home }}"
      when: docker_version.stdout == ''

    - name: Extract binary
      unarchive:
        src: "{{ _home }}/docker-{{ _docker_version }}-ce.tgz"
        dest: "{{ _home }}/"
        remote_src: yes
        creates: "{{ _home }}/docker/dockerd"
      when: docker_version.stdout == ''

    - name: Copy Docker Binaries to /usr/bin
      shell: cp {{ _home }}/docker/docker* /usr/bin/
      args:
        creates: /usr/bin/docker
      become: true

    - name: start docker
      shell: dockerd &
      become: true
      args:
        creates: /var/run/docker.pid
      register: tmp

    - name: Debug
      debug:
        var: tmp

其结果如下:
