docker-composeI cannot stress enough what a fucking waste of time it is to learn
docker-compose in 2021. There is nothing it does that Kubernetes
doesn’t do better and with more opportunity for growth. But, seriously,
you have to be bordering on stupid to maintain any cognitive resources
dedicated to docker-compose at this point. Here’s why.
The overwhelming industry direction is to use Kubernetes for
everything. Even Google’s own internal teams are moving off of BORG to
Kubernetes. Meanwhile, a few people are still using docker-compose
mostly because that is what they started with or because they find it
somehow to be simpler.
Re-invest all that mental energy into truly learning Kubernetes and
kind locally for everything. Then all your knowledge will apply to the
enterprise and edge as well as your own personal development.
