Changes

Features

  • Add timestamps in logs (#802):sparkles:

    Add timestamp in the logs of the pipelines controller, webhook, and eventlisteners.

  • Improve the error message when URL form encoding is received (#806)

    The GitHub interceptor now detects form-encoded hook requests and returns an explicit error for this case rather than the generic JSON parsing error.

  • Allow users to set resources as part of podtemplate (#815)
    Now trigger allow users to specify their resource information in eventlistener

    apiVersion: triggers.tekton.dev/v1alpha1
kind: EventListener
metadata:
  name: github-listener-interceptor
spec:
  ...
  resources:
    kubernetesResource:
      spec:
        template:
          spec:
            serviceAccountName: tekton-triggers-github-sa
            containers:
              - resources:
                  requests:
                    memory: "64Mi"
                    cpu: "250m"
                  limits:
                    memory: "128Mi"
                    cpu: "500m"

  • Use Listers to fetch data in the Sink(#821)

    EventListener ServiceAccounts now need to have "list" and "watch" verbs in addition to "get" for all triggers resources. See examples at https://github.com/tektoncd/triggers//tree/v0.10.0//examples/role-resources/triggerbinding-roles/role.yaml and https://github.com/tektoncd/triggers/tree/v0.10.0//examples/role-resources/clustertriggerbinding-roles/clusterrole.yaml

  • Add Timeout for EventListener Server (#747)

    Add Read, Write, and Idle timeout for connections to the EventListener.

  • TEP-0022: Switch to immutable input event bodies (#828)
    Migrate CEL to new Interceptor Interface

  • Add EventListener Selector For TriggerCRD (#773)
    Added Namespace Selector field for EventListener which enables EventListener to serve across the namespace. namespaceSelector field with matchNames need to be provided to enable selector.

    namespaceSelector:
  matchNames:
  - nsName1
  - nsName2

If namespace selector is used, the service account for the EventListener will need a clusterRole. See the example at https://github.com/tektoncd/triggers/tree/v0.10.0/examples/selectors/01_rbac.yaml

  • Allow secure connection to eventlistener pod (#819)
    HTTPS connection to eventlistener can be configured by tweaking eventlistener configuration 
     apiVersion: triggers.tekton.dev/v1alpha1
 kind: EventListener
 metadata:
   name: github-listener-interceptor
 spec:
   ...
   resources:
     kubernetesResource:
       spec:
         template:
           spec:
             serviceAccountName: tekton-triggers-github-sa
             containers:
             - env:
               - name: TLS_CERT
                 valueFrom:
                   secretKeyRef:
                     name: tls-key-secret
                     key: tls.crt
               - name: TLS_KEY
                 valueFrom:
                   secretKeyRef:
                     name: tls-key-secret
                     key: tls.key
  • Drop escaping of strings in the JSON (#823)
    Change the escaping of parameters into TriggerTemplates.

Backwards incompatible changes 🚨

In the current release:

  • TEP-0022: Switch to immutable input event bodies (#828)

    action required: If you are using overlays in the CEL Interceptor, please update your bindings to use $(extensions.) instead of $(body.)

    BREAKING CHANGE:
    CEL overlays now add fields to a new top level extensions field instead of the modifying the incoming event body. TriggerBindings can access values within this new extensions field using $(extensions.<key>) syntax.

  • Drop escaping of strings in the JSON (#823)

    Previously, parameters were escaped as they were being replaced into a TriggerTemplate, by replacing double-quotes " with an escaped version ", this functionality has been removed, as it was breaking quoted strings, and in some cases, rendering the resulting output unparseable.

    action required: If you were relying on the escaping, you can retain the old behaviour by adding an annotation to an affected TriggerTemplate, triggers.tekton.dev/old-escape-quotes: "true"
