I don't like to install too many services on my machine as after a while I end up with lots of services - Postgres, Redis, Mongo, Memcache, Elasticsearch that have lots of data from different POC projects.
So whenever I need to test something quickly I just prefer to run it in a docker container:
docker run --name postgres -d -p 5432:5432 -e POSTGRES_PASSWORD=kuba -e POSTGRES_DB=db -e POSTGRES_USER=kuba postgres:12
Or with docker compose:
version: '3'
services:
postgres:
image: postgres:12
environment:
- POSTGRES_USER=kuba
- POSTGRES_PASSWORD=kuba
- POSTGRES_DB=db
ports:
- "5432:5432"
And we can quickly run the Postgres DB:
$ docker-compose up
Starting sql_postgres_1 ... done
Attaching to sql_postgres_1

And we have a throwaway db running:
$ psql postgres://kuba:kuba@localhost:5432/db
Null display is "NULL".
Pager is always used.
Timing is on.
psql (12.2)
Type "help" for help.
kuba@localhost:5432 db#
