Use pyinfra instead of a Dockerfile to build docker images?

[dahjelle]

Is it reasonable to use pyinfra to build docker images as a replacement for a Dockerfile?

(I'm a new to both, so I may be missing something obvious.)

I tried the getting started example, removing my-server.net from the inventory. I also had to remove the _sudo=True line and add apt.update() into the deploy.py file.

pyinfra finishes with the line:

    [@docker/ubuntu:18.04] docker build complete, image ID: d459fd5d33fa

But docker image ls doesn't show an image with that ID!

% docker image ls
REPOSITORY                TAG         IMAGE ID      CREATED         SIZE
<none>                    <none>      fc3d129d459f  27 seconds ago  58.9 MB
docker.io/library/ubuntu  18.04       d1a528908992  11 months ago   58.9 MB

(I was also expecting to be able to tag the image, as I would in the first line in a Dockerfile.)

It does appear that if I run the fc3d129d459f image that it is what I'm looking for.

I'm probably missing some basic concepts, but if someone has a moment to point me in the right direction, I'd appreciate it!

I don't see any reason not to! I actually would like to go full circle and implement a connector that writes Dockerfiles based on operations, empty PR waiting for it: https://github.com/pyinfra-dev/pyinfra-dockerfile-connector
