Helm values reference

All the options of the chart, with their defaults, as found in charts/pinglow/values.yaml.

Controller (pinglow)

Value	Default	Description
pinglow.db.secretName	pinglow-db-credentials	Secret with DB_HOST, DB_USER and DB_USER_PASSWORD of an external database. Ignored when timescaledb.enabled=true.
pinglow.dbRetentionCheckResults	"7 days"	Retention of check results. Any PostgreSQL INTERVAL, see data retention.
pinglow.dbRetentionPerfData	"7 days"	Retention of performance data.
pinglow.OidcEnvFromSecret	pinglow-oidc	Secret with the OIDC settings. Optional: if the Secret does not exist OIDC is disabled. See OIDC authentication.
pinglow.extraCAConfigMap	""	ConfigMap with a ca.crt key, trusted when contacting the OIDC provider.
pinglow.resources	requests 250m / 256Mi, limits 500m / 512Mi	CPU and memory of the controller.

Runner (runner)

The runners execute the checks. Their number is only adjusted automatically when keda.enabled=true; otherwise minReplicas replicas are run.

Value	Default	Description
runner.minReplicas	1	Minimum (and, without KEDA, fixed) number of runners.
runner.maxReplicas	10	Maximum number of runners.
runner.queueLengthThreshold	10	Number of pending checks in the queue that triggers scaling out.
runner.activationThreshold	1	Number of pending checks needed to activate scaling.
runner.pollingInterval	15	How often, in seconds, KEDA checks the queue.
runner.cooldownPeriod	300	Seconds to wait before scaling down.
runner.resources	requests 500m / 256Mi, limits 1000m / 512Mi	CPU and memory of each runner.

Autoscaling (keda)

Value	Default	Description
keda.enabled	false	Creates a KEDA ScaledObject for the runners, based on the Redis queue. Requires KEDA installed in the cluster.

Redis (redis)

Value	Default	Description
redis.secretName	""	Secret with a REDIS_PASSWORD key. When empty, the chart generates one named pinglow-redis-password.

Bundled TimescaleDB (timescaledb)

Single instance for development and testing, see Deployment.

Value	Default	Description
timescaledb.enabled	false	Deploys TimescaleDB together with Pinglow.
timescaledb.image.repository	timescale/timescaledb-ha	Image repository.
timescaledb.image.tag	pg18	Image tag.
timescaledb.image.pullPolicy	IfNotPresent	Image pull policy.
timescaledb.secretName	""	Own credentials Secret, with POSTGRES_USER and the password key. When empty, the chart generates pinglow-db-credentials.
timescaledb.username	postgres	Database user of the generated Secret.
timescaledb.database	pinglow	Name of the database.
timescaledb.passwordKey	POSTGRES_PASSWORD	Key holding the password in the credentials Secret. Change it only together with timescaledb.secretName: the generated Secret always uses POSTGRES_PASSWORD.
timescaledb.persistence.enabled	true	Store the data on a PersistentVolumeClaim.
timescaledb.persistence.storageClassName	""	Storage class of the PVC (cluster default when empty).
timescaledb.persistence.accessModes	[ReadWriteOnce]	PVC access modes.
