腾讯云~安装Docker

1. 卸载旧版docker

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

2. yum包更新到最新

yum update

3. 安装依赖

需要的软件包(yum-utils提供yum-config-manager的功能,，并且device mapper存储驱动程序需要device-mapper-persistent-data和lvm2)在这里插入代码片

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

4. 设置yum源为阿里云

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

5. 安装docker

sudo yum install docker-ce docker-ce-cli containerd.io docker-compose-plugin

6. 安装后查看docker版本

docker -v

7. 阿里云镜像加速

sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-'EOF'
{
  "registry-mirrors": ["https://73z5h6yb.mirror.aliyuncs.com"]
}
EOF
sudo systemctl daemon-reload
sudo systemctl restart docker
