Docker开启Remote API访问 Docker开启Remote API访问方法一1、修改/usr/lib/systemd/system/docker.service配置，在[Service]部分ExecStart后面添加配置。-H tcp://0.0.0.0:2375修改后如下：[Service] Type=notify # the default is not to use systemd for cgroups because the delegate issues still # exists and systemd currently does not support the cgroup feature set required # for containers run by docker ExecStart=/usr/bin/dockerd -H fd:// --containerd=/run/containerd/containerd.sock -H tcp://0.0.0.0:2375 ExecReload=/bin/kill -s HUP $MAINPID TimeoutSec=0 RestartSec=2 Restart=always2、重新加载配置文件systemctl daemon-reload systemctl restart docker方法二修改配置sudo vim /etc/default/docker加入下面配置DOCKER_OPTS="-H tcp://0.0.0.0:2375"重新加载配置文件sudo systemctl restart docker方法三修改配置文件daemon.jsonvim /etc/docker/daemon.json加入下面配置{ "hosts": ["tcp://0.0.0.0:2375", "unix:///var/run/docker.sock"] }tcp socket，表示允许任何远程客户端通过 2375 端口连接 Docker Daemon。unix，本地客户端将通过这个来连接 Docker Daemon。重新加载配置文件systemctl daemon-reload systemctl restart docker检查是否开启ps -ef|grep docker即可看到端口是否开启。
