quick question can I count on meltano being in a python 3 docker env for this kubernetes stuff? I like f strings and want to use that lol

For sure! The

meltano/meltano

image is based on

python:3.6

, right now, and Meltano officially supports 3.6 and 3.7. At some point we'll add 3.8 support: https://gitlab.com/meltano/meltano/-/issues/1956, but either way we'll never go back to Python 2 😜
