Run with docker-compose

env POSTGRES_PASSWORD="STRONG_PASSWORD" APP_DSN="postgres://postgres:postgres@db:5432/example?sslmode=disable" docker-compose --env-file .env.example up --build

env POSTGRES_PASSWORD="postgres" this command adds envoirment variable then available in docker compose.

APP_DSN contains connection string to the dockerezed postgres.

❗IMPORTANT: Host value in DSN must have name of service from docker-compose. In our case hostname is db.

Also, port have to be right side value after semicolon, it's a port of service available in docker isolated network, the left port for access from outside (host OS). In our case: "5433:5432" port 5432 for docker isolated network.

Overall, your DSN for docker should be like this: postgres://postgres:postgres@db:5432/example?sslmode=disable.

--build flag force docker compose to rebuild app. For example, if you have changed source code, you need this flag.
