Docker CLI

container

• docker ps shows all running container

  • docker ps -a shows all existing container

• docker run [OPTIONS] IMAGE[:TAG|@DIGEST] [COMMAND] [ARG...]

  • --name <container-name> gives the created container a custom name
  • --rm removes the container after stoping
  • -d detached mode - stops the container after main process exits usually not desired
  • -it for interactive processes - keep STDIN open (i), allocate a pseudo-tty (t)

• typical example for testing: docker run -it --rm --name test php:7.4 bash

• use bash in running container: docker exec -it containerName bash

network

• list networks docker network ls
• add a network connection docker network connect [OPTIONS] NETWORK CONTAINER

best practice

• use user flag: --user $(id -u):$(id -g) to avoid problems on creating and accessing files
