The easiest way to set up your own PostgreSQL instance is to pull a Docker image. You can find the official Docker configuration here: https://hub.docker.com/_/postgres
Download a Docker image version by running the following or a similar command:
docker pull postgres
then run it:
docker run -p 5432:5432 --name postgresql -e POSTGRES_DB=gms -e POSTGRES_PASSWORD=Secret -d postgres
If everything goes fine, you can see the following in your Docker client:
then try to connect to the database with your preferred DB client.
