OneGate is a legacy-free single-sign on service. It uses rather passkeys or fido2 stick for user authentication than passwords.
This project is using devcontainer. It is using podman and podman-compose to get it up and running.
As database only MariaDB is currently supported. In case you need access while you developing, you could use podman exec -ti onegatedevcontainer_db_1 /bin/bash -c 'mysql -h 127.0.0.1 -u root --password=$MARIADB_ROOT_PASSWORD $MARIADB_DATABASE'.
