上系統程式課程所用的 Docker Image

Posted on | In

系統程式需要使用到 Ubuntu 環境，但是手頭上的電腦是 Unix-based 的 MacOS。實在是不想裝設虛擬機畢竟太佔空間，所以就來玩個 docker，效果真的奇佳！

感謝光宇大大的神支援！讓這個 dockerfile 可以這麼完美。

目前已經 deploy 到 DockerHub 上，可以直接 pull 下來，不用自己 build 囉！

基本用法

  • build: 在有 dockerfile 的目錄底下，執行 docker build -t [image name] --no-cache --rm . 即可
  • create container (first time): docker run -p22222:22 --cap-add SYS_PTRACE -v [absolute path on local machine : absolute path in docker container] -dt [image name/id]
    • ssh ubuntu@localhost -p 22222 來連入 container，密碼為ubuntu
  • list containers: docker ps -a
  • list images: docker images -a
  • stop container: docker stop [ps ID]
  • remove stopped container: docker rm [ps ID]
  • stop and remove all containers:
    1
    2
    docker stop `docker ps -aq` // stop all ps
    docker rm `docker ps -aq` // remove all ps
