Use an external database¶
By default, Substra components use their own integrated postgres databases (one per backend, and one for the orchestrator in centralized mode).
They can be pointed to any PostgreSQL instance (version 11 or better).
The backend and orchestrator use the same structure in their values:
database: host: my.db.com port: 5432 auth: username: my-username password: my-password database: my-substra-db
Or, for improved security, you can create a secret with your database credentials, under the
DATABASE_USERNAME keys. Secrets can be made very secure but this is the basic example:
apiVersion: v1 kind: Secret metadata: name: my-db-secret stringData: DATABASE_PASSWORD: my-password DATABASE_USERNAME: my-username
And then point to it in the values, instead of using username & password:
database: host: my.db.com port: 5432 auth: database: my-substra-db credentialsSecretName: my-db-secret
