Javaopts-operator

Operator for benchmark testing of Java-based Knative applications

This operator is designed for running knative-quarkus-bench with CPE. You can also run this operator w/o CPE.

What this operator do

• Create/Update a configMap of JVM options that a Knative app service refers
• Delete the pods of the target Knative app to apply the configMap
• Create and Run a driver job for your Knative app that sends requests and collect logs of the target Knative app pod

How to use this operator as a benchmark operator of CPE

0. Run Knative service of your application

$ kubectl create -f broker.yaml -f sleep_ksvc.yaml -f sleep_trigger.yaml

If the process completion of your knative application after traffic ends would take longer than 30 secs, you had better to disable enable-scale-to-zero or increase scale-to-zero-grace-period in your environment. For each service, you can configure scale-to-zero-pod-retention-period as below:

kind: Service
apiVersion: serving.knative.dev/v1
metadata:
  name: sleep 
spec:
  template:
    metadata:
      annotations:
        autoscaling.knative.dev/scale-to-zero-pod-retention-period: "5m"
    spec:
      containers:
......

1. Deploy CPE

2. Build an image of this operator if needed Please see Makefile to configure image registry

$ cd javaopts-operator
$ make generate
$ make manifests
$ make docker-build docker-push

3. Run this operator

$ kubectl create -f jvmopts_operator.yaml

You can found their resources in the namespace jvmopts-operator.

$ kubectl get all -n jvmopts-operator
NAME                                    READY   STATUS    RESTARTS   AGE
pod/jvmopts-operator-6f549bcbdd-b4gsm   1/1     Running   0          43s

NAME                               READY   UP-TO-DATE   AVAILABLE   AGE
deployment.apps/jvmopts-operator   1/1     1            1           43s

NAME                                          DESIRED   CURRENT   READY   AGE
replicaset.apps/jvmopts-operator-6f549bcbdd   1         1         1       43s

4. Create benchmark resouce for CPE

$ kubectl create -f cpe_knative_sleep.yaml

Then, CPE creates jobs of a driver for your application.

How to use this operator w/o CPE

0. Run Knative service of your application
1. Build an image of this operator if needed Please see Makefile

$ cd javaopts-operator
$ make generate
$ make manifests

2. Deploy

$ make deploy
