Generally following instructions from https://hbase.apache.org/book.html#quickstart. Interesting notes and specific suggestions:
This quick guide will spin up a Postgres 12 container accessible from localhost:9432. This is NOT a durable setup and data is very likely to be lost after the database is shutdown. For demo purposes only.
In one shell, run
$ docker run -e POSTGRES_PASSWORD=postgres --publish 9432:5432 --name demo-pg12 postgres:12
