Docker create image manually - placeholders

  • Run conatiner
docker run -it --name NAME BASE_CONTAINER:BASE_TAG

  • install stuff in the container, copy stuff to the container, exit

  • Create image from container

docker container commit CONTAINER NEW_IMAGE_NAME:TAG
  • Better yet, create the container under your Docker Hub username:
docker container commit CONTAINER USERNAME/NEW_IMAGE_NAME:TAG
  • To verify, run a container based on the new image (with or without username):
docker container run --rm -it NEW_IMAGE_NAME:TAG
docker container run --rm -it USERNAME/NEW_IMAGE_NAME:TAG
