This is pids-geoconnex-mysql, used as the host directory for the internetofwater/yourls-mysql docker image.
This container is run during the Github workflow.
The mysql folder is used to build mysql and internetofwater/yourls-mysql images during the Github workflow. Initially mysql is created using schema.sql.gz. At the end of the workflow internetofwater/yourls-mysql is created using yourls.sql.gz.
schema.sql.gz is an empty backup of the yourls database with an empty yourls_url table and the specified yourls_options plugins enabled. internetofwater/yourls-mysql includes both /docker-entrypoint-initdb.d/schema.sql.gz and the workflow generated backup /docker-entrypoint-initdb.d/yourls.sql.gz. schema.sql.gz is redundant when yourls.sql.gz is included,because schema.sql.gz is executed before yourls.sql.gz. Each backup drops and rebuilds all the tables in the yourls database.
The Dockerfile moves all files from this directory (.) to /docker-entrypoint-initdb.d/. Therefore:
- With just
schema.sql.gz: Build container with empty yourls database for MySQL with plugins enabled. - With yourls.sql.gz: Build container with yourls database populated with the most recent database backup.
