  • docker rmi [ID]: remove image
  • docker run -it [IMAGE]: run image
  • docker run -it --rm [IMAGE]: run image and remove it after exit
  • docker run -it --rm -v [HOST_PATH]:[CONTAINER_PATH] [IMAGE]: run image and mount volume
  • docker run -it --rm -v [HOST_PATH]:[CONTAINER_PATH] -p [HOST_PORT]:[CONTAINER_PORT] [IMAGE]: run image and mount volume and expose port

Docker Compose ​

  • docker-compose up: start containers
  • docker-compose up -d: start containers in background
  • docker-compose down: stop containers
  • docker-compose down -v: stop containers and remove volumes

Options ​

Allow non-root user to run docker ​

sh
sudo docker login

Shortcuts ​

You can create shortcuts for docker commands by adding aliases to your ~/.zshrc or ~/.bashrc.

sh
vim ~/.zshrc
bash
alias d-clean='docker image prune -f -a && docker volume prune -f -a'
alias d-clean-network='docker network prune -f'
alias d-clean-container='docker container prune -f -a'
alias d-ps='docker ps --format "table {{.ID}}\t{{.Image}}\t{{.Status}}\t{{.Names}}"'
alias d-stats='docker stats --format "table {{.Name}}\t{{.CPUPerc}}\t{{.MemUsage}}\t{{.NetIO}}"'
alias dc='docker compose'
~/.zshrc
