Put the docker-compose.yaml into a new folder, along with a folder called /migrations. Put the sample SQL in there at /migrations/any-name.sql. This will seed the MySQL DB on startup.

Run docker-compose up -d, and visit Hasura at http://localhost:8080

Note: If you would like to a connect to an existing MySQL DB running outside of Docker on localhost, you will need to edit the configuration for the Hasura service so that it uses host networking. Then use localhost for the --mysql-host argument. Also, in order for Hasura on localhost to connect to the Docker Postgres instance, you'll need to add 5432:5432 to the service port configurations for postgres so that it's exposed, then change the DB URL to postgres://postgres:postgrespassword@localhost:5432/postgres.
