使用 ansible 在 RHEL VM 上安装 Docker
Install Docker on RHEL VM using ansible
我想使用 Ansible 从远程 RHEL VM 上的二进制文件安装 Docker CE。我已按照 guide 中提到的步骤制作了剧本。我跳过了可选的第三步，因为我使用的是可执行文件的完整路径。但是，当我的脚本进入第 4 步时 - 启动 Docker 守护程序，它不会启动。
我看到的调试输出是：

这是我的 Ansible 剧本：
---

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

unarchive:

dest: /root/
remote_src: yes
when: docker_version.stdout == ''
- name: start docker
shell: sudo /root/docker/dockerd &
register: tmp
- name: Debug
debug:

附带说明一下，我登录到远程虚拟机并 运行
ls -al docker
并发现我在提取二进制文件后得到的目录 docker 属于一个组 vradeploy。这是输出：

刚刚花了一点时间让你看看我是否能弄明白。下面的剧本是我为您整理的，确实有效。虽然它与您的原始代码有点不同。但只是想和你分享一下，看看对你有没有帮助。
- hosts: test_nodes
vars:
_docker_version: 17.12.0
tasks:

become: true
- name: Setting HOME Directory Path
set_fact:

刚刚花了一点时间让你看看我是否能弄明白。下面的剧本是我为您整理的，确实有效。虽然它与您的原始代码有点不同。但只是想和你分享一下，看看对你有没有帮助。
- 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 }'
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:

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/
