Metadata Database

Debug Information

Image: docker.io/bitnami/mariadb-galera:11.1.3-debian-11-r8

• Ports: 3306/tcp
• JDBC: jdbc://mariadb:<hostname>:3306

To directly access in Kubernetes (for e.g. debugging), forward the svc port to your local machine:

kubectl [-n namespace] port-forward svc/metadata-db 3306:3306

Overview

The metadata database is the single, central source of truth within DBRepo and holds all metadata information for interaction between the services and displaying information in the UI.

On the first start, the schema is generated by the file /docker-entrypoint-initdb.d/setup-schema.sql within the container. You can add custom files that should be executed on the first start by placing them into the /docker-entrypoint-initdb.d/ folder as well. For example:

services:
  dbrepo-metadata-db:
    ...
    volumes:
      - /path/to/setup-schema.sql:/docker-entrypoint-initdb.d/1_setup-schema.sql
      - /path/to/setup-data.sql:/docker-entrypoint-initdb.d/2_setup-data.sql
    ...

1.4.4

We recommend to use the MariaDB image directly instead of our own maintained image which just copied the setup-schema.sql into the container. This can be done more transparently through volume mounts.

Alphabetic Filename Sorting

Beware that the init script provided by Bitnami executes files in alphabetic order! For example: the file setup-schema.sql is executed after the file setup-data.sql! Thefore a sorting prefix 1-9 is recommended!
