Run a MySQL/MariaDB Sidecar
Some upstream services require MySQL or MariaDB instead of PostgreSQL. Each engine has its own health checks, lifecycle tools, and dump-based backup builder.
Solution
Configure the database daemon with --bind-address=127.0.0.1 and pass its database and password environment variables. Health-check MySQL by execing mysql -e 'SELECT 1'; MariaDB images can use their healthcheck.sh script. Use sdk.Backups.withMysqlDump() for MySQL and sdk.Backups.withMariadbDump() for MariaDB. Each builder runs the engine’s native initialization, server, client, and dump tools from the selected image. A MariaDB daemon whose ready check is healthcheck.sh runs the official image’s entrypoint with MARIADB_AUTO_UPGRADE=1, which adds the healthcheck users to a restored data directory on its next start.
