Michael Semb Wever commented on CASSANDRA-20181:
------------------------------------------------
I would be in favour of finding existing public docker images for different
python versions, and updating the readme to reference them.
We don't need to be asking the user to have to build docker images themselves
to do this.
We don't need to be keeping these dockerfiles ourselves (and regularly having
to fix/update them).
And we don't need these dockerfiles to be testing different versions of python
in our CI (the testing scripts from 5.0 already provide that capability). And
we definitely shouldn't be placing the QA burden of cqlsh working on different
python versions on the user with manual testing.
