Fix ubuntu version in dockerfiles about libpython-clj HOT 6 OPEN

Right - sorry - my opinion is to upgrade to latest stable Ubuntu

from libpython-clj.

@behrica - What version of docker are you using when you build images?

from libpython-clj.

@cnuernber I think its the ubuntu version, not docker version. ubuntu:latest is not a fixed version so it has changed since the scripts were run successfully.

from libpython-clj.

Regarding the problem of "interactive" asking for something:

I have seen this from time to time, and there are usually specific command line options to prevent them.
But it is indeed a good idea to freeze teh ubuntu versions in

This make its more future proof.

I use various ubuntu versions, so I am not sure what is guaranteed to not have this problem.

The best thing would be to find a continously maintained Docker image which has python + Clojure preinstalled, and just refer to it.

from libpython-clj.

The closetsI found was python + java:
https://github.com/jupyter/docker-stacks/blob/main/pyspark-notebook/Dockerfile

But is has a lot of other staff as well, so gets big.

from libpython-clj.

an other pproach is to use "devcontainers".
This separates "base image" and "features added to it".
I made a working one here:
