DevOps之Docker准备

1、安装Docker

yum -y install yum-utils device-mapper-persistent-data lvm2

yum makecache fast
yum -y install docker-ce

2、设置开机启动

systemctl enable docker
systemctl start docker
systemctl restart docker
systemctl stop docker
systemctl status docker

3、设置国内镜像源

vi /etc/docker/daemon.json
#按 I 键，粘贴
{ "registry-mirrors": ["https://cq20bk8v.mirror.aliyuncs.com"] }
按esc键 在输入  :wq

4、本地安装 docker-compose

yum install epel-release
yum install python3-pip 
pip3 install --upgrade pip 
pip3 install docker-compose  
这里会报错：ModuleNotFoundError: No module named 'setuptools_rust'
解决方法：pip3 install -U pip setuptools

 
docker-compose --version
