Usage

Prepare database:

$ docker pull mariadb:10.5
$ docker run -d --env MARIADB_USER=app --env MARIADB_PASSWORD=app123 --env MARIADB_ROOT_PASSWORD=123456 -p 127.0.0.1:3306:3306 mariadb:10.5
$ mysql -h 127.0.0.1 -u root -p123456
    > CREATE DATABASE IF NOT EXISTS appdb CHARACTER SET utf8mb4;
    > DROP USER 'app';
    > CREATE USER IF NOT EXISTS 'app' IDENTIFIED BY 'app123';
    > GRANT ALL ON appdb.* TO `app`;
    > exit

Local startup:

$ go run cmd/main.go -f config/local.yaml
