A operator that injects the jacoco agent into pods so you can collect coverage data when running tests against Java services deployed in kubernetes.

If you don't already have cert manager installed you will need to run:

helm repo add jetstack https://charts.jetstack.io && helm repo update && \
  helm upgrade --install --namespace cert-manager --create-namespace \
  cert-manager jetstack/cert-manager --set installCRDs=true --debug --wait

Add the helm repos helm repo add k8s https://curium-rocks.github.io/k8s-jacoco-operator fetch updates helm repo update.

Verify it worked helm search repo k8s and you should see something like.

NAME                                                    CHART VERSION   APP VERSION     DESCRIPTION                                       
k8s/k8s-jacoco-operator...      0.1.0           0.1.0           ......

Deploy the operator helm upgrade --install jacoco-operator k8s/k8s-jacoco-operator

Once you've deployed the operator you can add the following annotations to your pods in the same namespace and they will have the jacoco agent copied in and the appropriate env vars set so the agent used and the code is instrumented.

jacoco-operator.curium.rocks/inject: 'true',
jacoco-operator.curium.rocks/target-containers: 'api'

Coverage data will be saved to a PVC on process exit, you can force this with a rollout on a deployment or using exec to send a SIGINT signal to the process.

The following scripts are included in the NPM project configuration

• lint lints the source code using eslint
• lint:fix automatically fixes any lint errors that can be fixed automatically
• test uses jest to run test suites
• test:e2e runs e2e test suite, this requires an active helm:deploy
• build compiles the typescript into js and places it in the dist folder
• build:image builds the container image
• minikube:start create a minikube k8s cluster
• minikube:stop stop minikube but do not delete
• minikube:delete delete the minikube cluster
• helm:addRepos adds helm repos
• helm:deployCertManager deploy cert-manager for TLS
• helm:deploy deploy the app to k8s using helm
• helm:template print the k8s yaml that would be applied to k8s when using helm:deploy
• helm:uninstall remove the app from k8s
• helm:uninstallCertManager remove cert-manager from the k8s cluster
