Docker使用记录

  • 查看当前容器/镜像

    • 1
      2
      
      docker images
      docker ps
      
  • 下载镜像

    • 最新版本下载

      • 发布则把下面的pull改成push
      1
      
      docker pull *
      
    • 指定版本下载

      1
      
      docker pull []:version
      
    • 下载所有版本

      1
      
      docker pull -a []
      
  • 使用镜像

    • docker为容器,run相当于启动一个沙箱,我们在沙箱中运行某个指令.

      1
      
      docker run []:[version] COMMAND
      
  • 删除镜像

    • 1
      2
      
      docker rmi [-f] liuml07/giri
      #-f为强制删除
      

2020.02.09更新

若出现下述情况,则需要我们通过管理员权限运行.

Got permission denied while trying to connect to the Docker daemon socket at uni                                                  x:///var/run/docker.sock: Get http://%2Fvar%2Frun%2Fdocker.sock/v1.39/images/jso                                                  n: dial unix /var/run/docker.sock: connect: permission denied
  • 将本地文件添加到镜像中

    • 使用docker命令
      • 利用docker ps -a可以看到容器的ID 拷贝一张图片到容器的workspace目录下
      • docker cp /home/img_666.jpg xxx:/路径
    • 使用dockerfile

      • 1
        2
        3
        
          FROM nginx     # 利用docker hub中nginx镜像
          ADD ./workspace/img_666.jpg workspace/ 			# 添加一张图片
          WORKDIR /workspace								# 设定工作目录
        
  • 使用commit命令container打包成镜像

    也可以使用Dockerfile打包

    • 1
      
        docker commit -a "MetaNetworks" -m "OmpTG Online" 768a1e370dce omptg-online:v1
      
      • -a:作者
      • -m:镜像名称
      • 768a1e370dce:container的ID,可以通过docker container ls查看
  • 启动image

    • 1
      
        docker run --name omptg-online   -dit -P -p 8000:80 -p 8888:8888 omptg-online:v1 /bin/bash start.sh
      
    • -d:后台启动

    • -t:为容器重新分配一个伪输入终端,通常与-i同时使用

    • -i:以交互模式启动

    • -P:随机分配暴露的端口号

    • -p:设备的端口:container的端口映射

在container内的操作一定要少!!!否则根据docker层数关系管理,镜像会过大!
