Docker安装和配置

移除以前docker相关包

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

 

配置yum源

sudo yum install -y yum-utils
sudo yum-config-manager \
--add-repo \
http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

 

安装docker

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

 

配置加速（可以理解为类似于Maven的阿里仓库，用于加速镜像的下载速度）

#创建目录
sudo mkdir -p /etc/docker

#配置镜像
sudo tee /etc/docker/daemon.json <<-'EOF'
{
  "registry-mirrors": ["https://82m9ar63.mirror.aliyuncs.com"],
  "exec-opts": ["native.cgroupdriver=systemd"],
  "log-driver": "json-file",
  "log-opts": {
    "max-size": "100m"
  },
  "storage-driver": "overlay2"
}
EOF

 

启动

sudo systemctl daemon-reload
sudo systemctl restart docker
