I am leaving for today, small update:
I have implemented a first version of how to generate the container config files and I have added tests.
https://github.com/nf-core/tools/pull/3955
Tomorrow I will only be able to join for 1h or so in the morning, in case someone finishes their work and want to take over, this should be tested with a real case scenario when we have an example in place. I also updated the PR description with some TODOs 💪🏻
