Metagrid settings

The config: section of values.yaml will be passed through Helm's tpl function and the result will be stored in a Kubernetes Secret and mounted as environment variables in the Django backend pod. See Configurable Environment Variables for available environment variables.

Configuring Postgres

This chart includes the Bitnami Postgres-ha chart as a dependency by default. You can customize this instance using the postgres: key in values.yaml.

Using an external Postgres database

First, disable the included Postgres instance by setting postgres.enabled: false in values.yaml. Then, use the standard libpq environment variables in the config: section to point to the external Postgres instance. For example:

postgres:
  enabled: false

config:
  PGHOST: postgres.example.local
  PGUSER: metagrid_user
  PGPASSWORD: some_password

Using an external Node Status API endpoint

This chart includes a minimal Prometheus and Blackbox Exporter installation to serve the Node Status API. To use an existing or external Node Status API endpoint, disable the included instance and point METAGRID_STATUS_URL to your existing API endpoint:

nodeStatusBackend:
  enabled: false

config:
  METAGRID_STATUS_URL: https://thanos-querier.openshift-monitoring.svc.cluster.local:9092/api/v1/query?query=probe_success%7Bjob%3D%22http_2xx%22%2C+target%3D~%22.%2Athredds.%2A%22%7D
