The main objective of this part two is to learn how to build our image, to run our application/service. Two paths are discussed:

  • Building images interactively

    • Create a container from a base image.
    • Install software manually in the container, and turn it into a new image.
    • Learn about new commands: docker commit, docker tag, and docker diff.

  • Building docker images with Dockerfiles

    • Basic "instructions": a quick overview.
    • Write a Dockerfile.
    • details on CMD/ENTRIPOINT/COPY
    • Build an image from a Dockerfile.
    • A Python App example
    • Extra: multi-stage
