Chapter 12. Using ContainerSource with Service Mesh You can use container source with Service Mesh. 12.1. Configuring ContainerSource with Service Mesh This procedure describes how to configure container source with Service Mesh. Prerequisites You have set up integration of Service Mesh and Serverless. Procedure Create a Service in a namespace that is member of the ServiceMeshMemberRoll : Example event-display-service.yaml configuration file apiVersion: serving.knative.dev/v1 kind: Service metadata: name: event-display namespace: <namespace> 1 spec: template: metadata: annotations: sidecar.istio.io/inject: "true" 2 sidecar.istio.io/rewriteAppHTTPProbers: "true" spec: containers: - image: quay.io/openshift-knative/knative-eventing-sources-event-display:latest 1 A namespace that is a member of the ServiceMeshMemberRoll . 2 This annotation injects Service Mesh sidecars into the Knative service pods. Apply the Service resource: USD oc apply -f event-display-service.yaml Create a ContainerSource object in a namespace that is member of the ServiceMeshMemberRoll and sink set to the event-display : Example test-heartbeats-containersource.yaml configuration file apiVersion: sources.knative.dev/v1 kind: ContainerSource metadata: name: test-heartbeats namespace: <namespace> 1 spec: template: metadata: 2 annotations: sidecar.istio.io/inject": "true" sidecar.istio.io/rewriteAppHTTPProbers: "true" spec: containers: # This corresponds to a heartbeats image URI that you have built and published - image: quay.io/openshift-knative/heartbeats name: heartbeats args: - --period=1s env: - name: POD_NAME value: "example-pod" - name: POD_NAMESPACE value: "event-test" sink: ref: apiVersion: serving.knative.dev/v1 kind: Service name: event-display-service 1 A namespace that is part of the ServiceMeshMemberRoll . 2 These annotations enable Service Mesh integration with the ContainerSource object. Apply the ContainerSource resource: USD oc apply -f test-heartbeats-containersource.yaml Optional: Verify that the events were sent to the Knative event sink by looking at the message dumper function logs: Example command USD oc logs USD(oc get pod -o name | grep event-display) -c user-container Example output ☁\ufe0f cloudevents.Event Validation: valid Context Attributes, specversion: 1.0 type: dev.knative.eventing.samples.heartbeat source: https://knative.dev/eventing-contrib/cmd/heartbeats/#event-test/mypod id: 2b72d7bf-c38f-4a98-a433-608fbcdd2596 time: 2019-10-18T15:23:20.809775386Z contenttype: application/json Extensions, beats: true heart: yes the: 42 Data, { "id": 1, "label": "" }
