Database connections

Superset requires a metadata database for storing slices, connections, tables, dashboards and other metadata. The actual connection string is calculated by the operator so that the user does not need to remember the exact structure.

Typed connections

spec:
  clusterConfig:
    metadataDatabase:
      postgresql: (1)
        host: superset-postgresql
        database: superset
        credentialsSecretName: superset-postgresql-credentials (2)

1	A reference to one of the supported database backends (e.g. `postgresql`).
2	A reference to a Secret which must contain the two keys `username` and `password`.

Generic connections

Alternatively, these connections can also be defined in full in a referenced Secret:

spec:
  clusterConfig:
    metadataDatabase:
      generic:
        connectionUrlSecretName: superset-metadata (1)

1	A reference to a Secret which must contain the single key `connectionUrl` e.g. `postgresql://superset:superset@superset-postgresql/superset`
