Postgres & Flyway & Docker

Runs a Postgres DB accessible on localhost:5432

Only Dependency is Docker

Found myself using this same pattern in team projects to quickly get a database running for local dev purposes so figured it might be useful to some other devs.

The Makefile is the original component, comments should explain what the commands do.

Database.sh was created for a Windows friendlier version, you'll still need a terminal that supports PWD. I haven't used it beyond testing basic functionallity but teammates have been using it without issue.

Example

Shows normal usage of each command, notice that make stop is data safe, make clean is not and requires a make init afterwards.

20:17:47 hunterlogan postgres-flyway-docker$ make init
docker run -itd \
	--name postgresql \
	-p 5432:5432 \
	--env POSTGRES_PASSWORD='12345678' \
	--env POSTGRES_USER='postgres' \
	--env POSTGRES_DB='postgres' \
	postgres:12
