JSON querying and interpolation in Postgres SQL columns

postgres_json_practice

This repo contains postgres 13.0 JSON interpolation and querying using docker as an environment wrapper.

It's two exercises wrapped into one:

1. Working with docker and postgres in a variety of ways.
2. JSON and JSONB querying.

Instructions and Use

There are four examples demonstrating a variety of ways to spin up a dockerized postgres instance.

See: Basic Docker Operations

Notes

1. Create a new superuser via SQL script rather than passing in a POSTGRES_USER ENV variable.
2. The POSTGRES_USER ENV variable is not used to connect in docker but through a 3rd party GUI client like pgadmin or postico.
