Kubernetes ConfigMap Sink¶

varTrack writes config values directly into a Kubernetes ConfigMap. Changes pushed to Git are reflected in the cluster automatically — no manual kubectl apply needed.

Configuration¶

datasources: [{
  configmap: {
    tag:        ""
    namespace:  "default"
    kubeconfig: "/path/to/kubeconfig"    // optional — uses in-cluster config if omitted
  }
}]

Destination template¶

The destination_template controls the ConfigMap name:

rules: [{
  platform:             "github"
  datasource:           "configmap"
  destination_template: "myapp-{env}"
}]

Push branch	ConfigMap created/updated
`main`	`myapp-production`
`develop`	`myapp-staging`

Config keys are stored as ConfigMap data entries:

apiVersion: v1
kind: ConfigMap
metadata:
  name: myapp-production
  namespace: default
data:
  database.host: "mongo.prod.internal"
  max_connections: "50"
  feature.dark_mode: "true"

Drift detection¶

The watcher reads the ConfigMap data and compares against the Git baseline. Any changed or missing key triggers a drift event.

rules: [{
  platform:   "github"
  datasource: "configmap"
  self_heal:  true
}]
