11.5 docker

树莓派实验室详细教程：https://shumeipai.nxez.com/2019/05/20/how-to-install-docker-on-your-raspberry-pi.html

rasp-pi

sudo curl -sSL https://get.docker.com | sh

安装完之后会提示:

If you would like to use Docker as a non-root user, you should now consider
adding your user to the "docker" group with something like:

  sudo usermod -aG docker store

Remember that you will have to log out and back in for this to take effect!

WARNING: Adding a user to the "docker" group will grant the ability to run
         containers which can be used to obtain root privileges on the
         docker host.
         Refer to https://docs.docker.com/engine/security/security/#docker-daemon-attack-surface
         for more information.

sudo usermod -aG docker store

macos

测试 Docker

运行 hello-world 镜像来做一个测试。

sudo docker run hello-world

如果 Docker 安装成功，你会看到一条消息：“Hello from Docker!”。

常用配置和工具命令

#查看 Docker 版本
docker -v
sudo docker pull 仓库/镜像:版本（留空的话默认为 latest）
sudo docker run 加参数，用来创建容器
#查看运行容器
sudo docker ps
#查看所有下载的镜像
sudo docker images
#进入容器终端
sudo docker exec -i -t ha /bin/bash
#实时查看10行的 ha 日志
sudo docker logs -f -t --tail 10 ha
#重启 systemctl 守护进程
sudo systemctl daemon-reload
#设置 Docker 开机启动
sudo systemctl enable docker
#开启 Docker 服务
sudo systemctl start docker

#下载 Docker 图形化界面 portainer
sudo docker pull portainer/portainer
#创建 portainer 容器
sudo docker volume create portainer_data
#运行 portainer
sudo docker run -d -p 9000:9000 --name portainer --restart always -v /var/run/docker.sock:/var/run/docker.sock -v portainer_data:/data portainer/portainer

在图形化界面中操作更加便利。运行之后在浏览器中输入树莓派IP:9000 进入界面。
