## 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**  

```actionscript
kubectl label namespace $NAMESPACE traceableai-inject-java=enabled
```
2. Enter the following command to **annotate the Java deployment**

```actionscript
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  

```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.

```actionscript
kubectl describe pod <POD> -n <NAMESPACE>
...
Init Containers:
  traceable-javaagent-init:
    Container ID:  docker://a71000bd5bc2eab1f03c76c3156f6c8105c64b5baaa2c3ef1fce9434cd62aed5
    Image:         traceableai/javaagent:1.0.0
...
```
