Docker - Tips

Container → Image

• Docker images

  • $ docker images
    REPOSITORY                      TAG       IMAGE ID       CREATED         SIZE
    fjvallarino/pytorch-geometric   latest    7ee3fe57718c   21 months ago   4.23GB
    

• Run the docker image as a container (or we can run the image on Docker Desktop)

  • $ docker run --name container_name fjvallarino/pytorch-geometric
    

• List running containers

  • $ docker ps
    CONTAINER ID   IMAGE                                  COMMAND       CREATED        STATUS         PORTS     NAMES
    cf66765c8f20   fjvallarino/pytorch-geometric:latest   "/bin/bash"   2 months ago   Up 8 seconds             container_name
    

• Running container → image

  • $ docker commit -a [AUTHOR] -m [COMMIT MSG] [CONTAINER NAME] [REPO]:[TAG]

  • $ docker commit -a "acousticwave" -m "commit_test" container_name acousticwave/pytorch-geometric:2022-06-11
    

• Check the built image

  • $ docker images
    REPOSITORY                       TAG          IMAGE ID       CREATED          SIZE
    acousticwave/pytorch-geometric   2022-06-11   a4cc2d1caf95   53 seconds ago   7.56GB
    

Image → Remote Repo.

• Docker Desktop can pushs the built image to a remote remote repository

Images > Push to Hub

• We can pull this image on other devices.

Remote Repo. > Pull

Sharing Host Path with Container Path

• Docker Desktop support sharing a Host(Local) Path with Container Path
  • Docker Desktop → Images → Run → Operation Settings
    • Container Name: Set Container Name
    • Volumes
      • Host Path: Define a path to be shared with a container (files in this path are uploaded to Container Path)
      • Container Path: Path to be connected to Host Path

Docker Desktop > New Container

Container Name / Host Path / Container Path

Attaching a Container to Visual Studio Code

• Open a Visual Studio Code window and install Docker and Remote Development extensions.
• And Run a Container (Setting of Host Path and Container Path required as explained above)

    acousticwave/pytorch-geometric   2022-06-11   a4cc2d1caf95   53 seconds ago   7.56GB
    

• Docker image → .tar file

  • docker save [OPTION] <FILENAME> [IMAGE-NAME]
