# Install Docker CLI
brew install docker
brew install docker-compose

Ubuntu Docker开启2375端口，支持远程访问

  • 编辑docker.service文件
    1
    vim /lib/systemd/system/docker.service
  • ExecStart属性添加参数-H tcp://0.0.0.0:2375
    1
    ExecStart=/usr/bin/dockerd -H fd:// --containerd=/run/containerd/containerd.sock -H tcp://0.0.0.0:2375
  • 重启
    1
    2
    systemctl daemon-reload
    systemctl restart docker
  • 测试是否开启成功

    docker run hello-world

    Status: Downloaded newer image for hello-world:latest

    Hello from Docker!
    This message shows that your installation appears to be working correctly.

    To generate this message, Docker took the following steps:
     1. The Docker client contacted the Docker daemon.
     2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
        (amd64)
     3. The Docker daemon created a new container from that image which runs the
        executable that produces the output you are currently reading.
     4. The Docker daemon streamed that output to the Docker client, which sent it
        to your terminal.

    To try something more ambitious, you can run an Ubuntu container with:
     $ docker run -it ubuntu bash

    Share images, automate workflows, and more with a free Docker ID:

在本机启动Ubuntu Docker（可选）

  • 安装multipass虚拟机管理软件
    1
    brew install --cask multipass
  • 创建Ubuntu虚拟机
    1
    multipass launch 20.04 --name my-docker -d 50G -m 2G
  • 在虚拟机中安装Docker
    1
    2
    multipass shell my-docker
    > curl -fsSL https://get.docker.com | sh
  • 编辑docker.service配置
    1
    sudo vim /lib/systemd/system/docker.service
  • 修改ExecStart添加-H tcp://0.0.0.0
    1
    ExecStart=/usr/bin/dockerd -H fd:// -H tcp://0.0.0.0 --containerd=/run/containerd/containerd.sock
  • 重启
    1
    2
    > sudo systemctl daemon-reload
    > sudo systemctl restart docker.service
  • 按Ctrl+D退出虚拟机
