Linux搭建Docker环境

1.确定是CentOS7及以上版本

cat /etc/redhat-release

2.linux可以联网

ping www.baidu.com

3.root用户安装yum

yum -y install gcc

yum -y install gcc-c++

yum install -y yum-utils

4.设置stable镜像仓库

yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

5.更新yum软件包索引

yum makecache fast

6.安装DOCKER CE

yum -y install docker-ce docker-ce-cli containerd.io

7.启动docker

systemctl start docker

docker version

systemctl status docker

 systemctl enable docker

8.镜像加速

mkdir -p /etc/docker

tee /etc/docker/daemon.json <<-'EOF'
{
  "registry-mirrors": ["https://uta146oq.mirror.aliyuncs.com"]
}
EOF

sudo systemctl daemon-reload

sudo systemctl restart docker

9.安装docker-compose

sudo curl -L https://github.com/docker/compose/releases/download/1.16.1/docker-compose-`uname -s`-`uname -m` -o /usr/local/bin/docker-compose

sudo chmod +x /usr/local/bin/docker-compose

docker-compose --version

10.自动补全

yum install -y bash-completion

source /usr/share/bash-completion/completions/docker

source /usr/share/bash-completion/bash_completion

11.卸载

systemctl stop docker 

yum remove docker-ce docker-ce-cli containerd.io

rm -rf /var/lib/docker

rm -rf /var/lib/containerd
