Ops here, Docker is packaging software.

Agree on the Kafka thing though. I've seen so many devs trip over Kafka topics, partitions and offsets when their throughput is low enough that RabbitMQ would do fine.

No, docker is a software for packaging systems.

The people distributing software should shut them damn up about how the rest of the system it runs in is configured. (But not you, your job is packaging full systems.)

That said, it seems to me that this is becoming less of a problem.
