Docker学习笔记

  # build并tag
  docker build -t imagename .

  # 将build好的image上传到docker hub
  docker login -u $username
  docker tag $imagename $username/$imagename
  docker push $username/$imagename

  # 查看运行的container
  docker ps
  
  # 查看所有的container
  docker ps -a
  
  # 查看container的配置情况
  docker inspect container-name

  # 直接获取目标容器的启动参数

  docker run --rm -v /var/run/docker.sock:/var/run/docker.sock assaflavie/runlike target-container-name

  # 可将上述命令设置别名
  alias drunlike="docker run --rm -v /var/run/docker.sock:/var/run/docker.sock assaflavie/runlike"

  # 查看容器的日志
  docker logs container-name

  # 显示所有的镜像
  docker image ls
  
  # 删除容器
  docker rm container-name

  # 删除镜像
  docker rmi imagename

  # 退出容器后自动删除
  docker run --rm  $imagename

  # 为用户添加docker用户组权限
  sudo usermod -aG docker your-username
  newgrp docker 

#创建群组并分配用户：
sudo synogroup --add docker
sudo synogroup --memberadd docker <username1> <username2> ...
sudo synogroup --get docker
#更改docker权限：
sudo chgrp docker /var/run/docker.sock
