Setting up the database

Create the initial db/user

Example for admindb:

create database admindb;
create user admindbuser;

Now in the newly created db:

CREATE EXTENSION IF NOT EXISTS "uuid-ossp";
grant execute on function uuid_generate_v4() to admindbuser;

This will grant the necessary permission to the newly created user to run uuid_generate_v4()

Run application migrations

We use golang-migrate to perform migrations.

Install golang-migrate

go install -tags 'postgres' github.com/golang-migrate/migrate/v4/cmd/migrate@latest

-tags 'postgres' is important as otherwise it compiles without postgres support

You can refer to the guide for full details.

Run migrations

Example for admindb:

export POSTGRESQL_URL='postgres://<user>:<pass>@<host>:<port>/admindb?sslmode=disable'
migrate -path ./persistence/migrations/admindb -database "$POSTGRESQL_URL" up

See cli-usage for more info.
