[Docker]CentOS7安装docker以及docker-compose

安装环境：CentOS7

参考官方文档：https://docs.docker.com/engine/install/centos/

一、卸载旧版本

yum remove docker \
                  docker-client \
                  docker-client-latest \
                  docker-common \
                  docker-latest \
                  docker-latest-logrotate \
                  docker-logrotate \
                  docker-engine

二、安装yum的软件包以及配置仓库地址（使用阿里云）

$ sudo yum install -y yum-utils

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

三、更新yum软件包索引

yum makecache fast

四、开始安装

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

五、启动docker

systemctl start docker
systemctl enable docker //允许开机启动docker

六、测试docker

docker version
docker run hello-world
docker images

七、卸载

systemctl stop docker
yum -y remove docker-ce docker-ce-cli containerd.io
rm -rf /var/lib/docker

八、阿里云镜像加速

sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-'EOF'
{
  "registry-mirrors": ["https://8fvmdddt.mirror.aliyuncs.com"]
}
EOF
sudo systemctl daemon-reload
sudo systemctl restart docker

九、docker-compose安装

sudo curl -L "https://github.com/docker/compose/releases/download/1.28.5/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
sudo chmod +x /usr/local/bin/docker-compose
sudo ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose
docker-compose --version //验证安装

十、docker-install.sh一键安装脚本

#!/bin/bash
yum remove docker \
                  docker-client \
                  docker-client-latest \
                  docker-common \
                  docker-latest \
                  docker-latest-logrotate \
                  docker-logrotate \
                  docker-engine
yum install -y yum-utils
yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
yum makecache fast
yum install -y docker-ce docker-ce-cli containerd.io
systemctl start docker
systemctl enable docker

mkdir -p /etc/docker

sudo tee /etc/docker/daemon.json <<-'EOF'
{
  "registry-mirrors": ["https://8fvmdddt.mirror.aliyuncs.com"]
}
EOF

sudo systemctl daemon-reload
sudo systemctl restart docker

sudo curl -L https://get.daocloud.io/docker/compose/releases/download/1.28.5/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose //国内镜像 
sudo chmod +x /usr/local/bin/docker-compose
sudo ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose
