I have deployed a spring boot application on a pod(pod1) on a node(node1). I have also deployed JMeter on another pod(pod2) on a different node(node2). I am trying to perform automated load testing from pod2. To perform load testing, I require to restart the pod1 for each test cases. How do I restart pod1 from pod2?
If you have a deployment type workload you can go into in through Workloads > [Deployment name] > Managed Pods [Pod name] and delete the pod.
You can also do this with kubectl delete pod [pod name]
If you have a minimum number of pods for that deployment set then GKE will automatically spin up another pod, effectively restarting it.

Via kubectl:
Install kubectl and configure in the pod2 and then do kubectl delete pod1 via shell after every load-testing
Via Springboot:
Add actuator dependency
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-actuator</artifactId>
</dependency>Enable shutdown
management.endpoint.shutdown.enabled=true
Request to shutdown
curl -X POST IP:port/actuator/shutdown
To restart or delete a pod from another pod you have to access the APIServer. There are many ways to do this check this link.
You also have to authorize the pod user to do this, build a Role and a Rolebinding entity.
