I recently started using proxmox and was planning on monitoring metrics using InfluxDB and Grafana, which I have already deployed on my Kubernetes cluster. However, during that process, I encountered two issues: Authentication “Database not found” Authentication For the Authentication issue, I found out that you have to use the Authorization header with the Token yourAuthToken value to access the bucket. So, configure the header name in the jsonData field, and we should configure the header value in secureJsonData for grafana helm chart values.

Tekton triggers and Interceptors

#Tekton #Triggers #Cel

Tekton Triggers work by having EventListeners receive incoming webhook notifications, processing them using an Interceptor, and creating Kubernetes resources from templates if the interceptor allows it, with the extraction of fields from the body of the webhook CEL Interceptors can filter or modify incoming events. For example, you can truncate the commit id from the webhook body. apiVersion: triggers.tekton.dev/v1alpha1 kind: EventListener metadata: name: shared-listener namespace: default spec: serviceAccountName: build-bot triggers: - name: shared-pipeline-trigger interceptors: - cel: overlays: - key: intercepted.commit_id_short expression: "body.head_commit.id.truncate(7)" bindings: - ref: pipeline-binding template: ref: pipeline-template The applied overlay uses an extension body in the binding. As shown in below example as $(extensions.<overlay_key>)
