  ],
  "data-root": "/data/docker/",
  "log-driver": "json-file",
  "log-opts": {
    "max-size": "500m",
    "max-file": "3"
  }
}

 systemctl daemon-reload
 systemctl restart docker
 docker info

安装docker compose

国外服务器下载地址及安装说明：https://docs.docker.com/compose/install/

从国外服务器下载并安装docker-compose,下载到 /usr/local/bin 目录就是安装。下载完成后授予执行权限。

sudo curl -L "https://github.com/docker/compose/releases/download/1.29.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
chmod +x /usr/local/bin/docker-compose

下载到 /usr/local/bin 目录就是安装。下载完成后授予执行权限。

查看是否下载成功。

ll /usr/local/bin/docker-compose

【第2步】验证否安装成功

验证docker-compose 是否安装成功：

docker-compose --version

卸载Docker-Compose

rm /usr/local/bin/docker-compose
