docker 安装请参考: docker - 环境搭建
- 修改配置
默认不支持远程访问, 需要修改配置以开启远程访问, 开启后, 可以远程执行 docker 命令
# 修改 /usr/lib/systemd/system/docker.service 文件
less /usr/lib/systemd/system/docker.service
================
# 替换前
ExecStart=/usr/bin/dockerd -H fd:// --containerd=/run/containerd/containerd.sock
# 替换后, 端口号 2375 可自定义
ExecStart=/usr/bin/dockerd -H tcp://0.0.0.0:2375 -H unix:///var/run/docker.sock --containerd=/run/containerd/containerd.sock
================
# 保存修改, 重启docker
systemctl daemon-reload
systemctl restart docker
- 接口文档
https://docs.docker.com/engine/api/v1.40
执行 docker versioin, 查看 API version, 获取版本号, 替换 v1.40
