By default, this playbook installs Postgres in a container alongside Gitea.
To use your own Postgres server, use a vars.yml configuration like this:
# Disable the integrated Postgres service
devture_postgres_enabled: false
# Uncomment and possibly change this, if you'd like to use another database engine.
# gitea_gitea_config_database_type: mysql
# Fill these out
gitea_gitea_config_database_hostname: ""
gitea_gitea_config_database_port: 5432
gitea_gitea_config_database_name: ""
gitea_gitea_config_database_username: ""
gitea_gitea_config_database_password: ""
