docker 部署ansible 环境

1、首先安装docker

sudo yum install -y yum-utils
sudo yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
sudo yum install -y docker-ce docker-ce-cli containerd.io
systemctl  start docker

2、设置开启开机自启

systemctl enable docker 
如果执行失败，可以用下面的命令手动执行
sudo ln -s /usr/lib/systemd/system/docker.service /etc/systemd/system/multi-user.target.wants/

3、可以给普通用户执行docker命令的权限，无需sudo

sudo usermod -aG docker $USER

4、拉取ansible镜像

docker pull registry.cn-shenzhen.aliyuncs.com/shine_fei/ansible_centos8:2.9.6
docker run -d --volume=/opt/ansible:/opt/ansible --restart=always  --name=ansible2.9 registry.cn-shenzhen.aliyuncs.com/shine_fei/ansible_centos8:2.9.6

5、进入docker

docker exec  -it ansible2.9 /bin/bash
[root@ff2ab1fc6d9d /]# ansible --version
