metabase-sql-wrapper is a docker-container based on Metabase container
that automatically saves Metabase H2 database to SQL-file (on docker stop)
and creates Metabase H2 database from SQL-file (on docker start if the database doesn't exists).

This allows to save the Metabase H2 database SQL-file to Git, versioning changes
and restore the database from SQL-file.

If you like the idea click ⭐ on the repo and stay tuned.

Run container

git clone https://github.com/anki-code/metabase-sql-wrapper
cd metabase-sql-wrapper
docker-compose up

How it works

  1. docker-compose.yml file has environment variables:

    MB_DB_FILE: /data/metabase
MB_DB_INIT_SQL_FILE: /data/metabase.db.sql     # (optional) used to build the DB if MB_DB_FILE doesn't exists 
MB_DB_SAVE_TO_SQL_FILE: /data/metabase.db.sql  # (optional) used to save SQL when container was stopped

  2. docker-compose up runs run.xsh with xonsh shell wrapper that catches the docker signals and environment variables and do saving or creating the Metabase DB after stopping or before starting the container.

  3. If MB_DB_INIT_SQL_FILE is set and MB_DB_FILE directory doesn't exists then before running Metabse the database will be created from the SQL-file.

  4. If MB_DB_SAVE_TO_SQL_FILE is set and the container will get stop/restart signal then the database will be saved to SQL-file after Metabase has been stopped.

This way you can run container, save your queries to Metabase, stop the container and commit it to Git.

Cleaning the database before commit to Git

By default Metabase writes logs and history to the database. To clean this before commit to Git you can use the metabase-db-clean.sql script:

java -cp metabase.jar org.h2.tools.RunScript -url jdbc:h2:./metabase.db -script /path/to/repository/metabase-db-clean.sql
