ansible安装docker

本文档主要介绍如何使用ansible在centos中快速安装时新版docker，目标服务器为一台阿里云ECS，安装操作系统为阿里云提供的公共镜像Centos7.9-64。

安装实践分为本地安装、远程安装两种，每次安装docker之前都会对ECS重装操作系统，且不预装任何服务和软件。

准备

硬件

一台阿里云ECS：1c2g40g 一台可以连接阿里云的linux服务器，预装ansible和git

基础环境

安装

本地安装

本地安装指直接ssh到目标服务器，进行安装。

安装基础组件

安装ansible

[root@myhost ~]# yum install -y ansible [root@myhost ~]# ansible --version ansible 2.9.27 config file = /etc/ansible/ansible.cfg configured module search path = [u'/root/.ansible/plugins/modules', u'/usr/share/ansible/plugins/modules'] ansible python module location = /usr/lib/python2.7/site-packages/ansible executable location = /usr/bin/ansible python version = 2.7.5 (default, Nov 16 2020, 22:23:17) [GCC 4.8.5 20150623 (Red Hat 4.8.5-44)] [root@myhost ~]#

安装git

[root@myhost ~]# yum install -y git [root@myhost ~]# git version git version 1.8.3.1

下载脚本

[root@myhost ~]# git clone ~]# cd ansible-examples/aliyun-cento79/ [root@myhost aliyun-cento79]# sh install-docker.sh localhost [WARNING]: provided hosts list is empty, only localhost is available. Note that the implicit localhost does not match 'all' PLAY [localhost] ***************************************************************************************** TASK [Gathering Facts] *********************************************************************************** ok: [localhost] TASK [docker : install required packages] **************************************************************** changed: [localhost] TASK [Add docker repositories] *************************************************************************** changed: [localhost] TASK [install docker] ************************************************************************************ changed: [localhost] TASK [docker : swap off is fstab] ************************************************************************ ok: [localhost] TASK [docker : swap is off] ****************************************************************************** changed: [localhost] TASK [mkdir /etc/docker] ********************************************************************************* changed: [localhost] TASK [docker etc is file] ******************************************************************************** changed: [localhost] TASK [restart docker] ************************************************************************************ changed: [localhost] RUNNING HANDLER [docker : yum-makecache] ***************************************************************** [WARNING]: Consider using the yum module rather than running 'yum'.

远程安装

本地安装指ssh到主控端，然后通过ansible将docker安装到目标服务器
