Install Java agent

Complete the following steps to install the Java agent. Make sure that you have identified the namespace in which you would like to auto inject the agent.

1. Enter the following command to label the namespace

   kubectl label namespace $NAMESPACE traceableai-inject-java=enabled

2. Enter the following command to annotate the Java deployment

   kubectl patch deployment.apps/<JAVA_DEPLOYMENT> -p '{"spec": {"template": {"metadata": {"annotations": {"java.traceable.ai/inject": "true"}}}}}' -n <NAMESPACE>

3. Restart the deployments in that namespace so that the Traceable platform agent can inject the Java agent into your deployment:ActionScript

   kubectl rollout restart deployment -n <NAMESPACE>

Verify

Check that the pods in the namespace have been injected with the Java agent by running the following command and verifying there is a traceable-javaagent-init initContainer.

kubectl describe pod <POD> -n <NAMESPACE>
...
