1. 開啓 TCP 端口

1.1 創建目錄/文件

mkdir -p /etc/systemd/system/docker.service.d
cat > /etc/systemd/system/docker.service.d/tcp.conf <<EOF
[Service]
ExecStart=
ExecStart=/usr/bin/dockerd -H unix:///var/run/docker.sock -H tcp://0.0.0.0:2375
EOF

1.2 重啓 docker 進程

systemctl daemon-reload
systemctl restart docker

1.4 查看端口是否打開

ps aux | grep dockerd | grep -v grep

2. 關閉 TCP 端口

rm -f /etc/systemd/system/docker.service.d/tcp.conf
systemctl daemon-reload
systemctl restart docker
ps aux | grep dockerd | grep -v grep
