I want to use JMeter with OS Sampler for load testing. Jmeter is deployed on Azure Kubernetes Service(AKS). Can we run executable inside AKS Pod ( Jmeter slave container will execute that exe inside pod)?
Regards, Amit Agrawal
I found another way, copy executable and all its binaries in JMeter slave using follwing command.
kubectl cp <source directory> <jmeter-slave-podname>:/<target directory>Provide all permission to target directory in jmeter slave pod.
you can run a second container in your pod using using the sidecar container approach.
If your Os Sampler needs access to the PID of your main application running in the other Container, you will need to turn on ShareProcessNamespace
https://kubernetes.io/docs/tasks/configure-pod-container/share-process-namespace/
this will allow your JMETER exe to see the PID of the other process in the same POD.
Here's an repo with some master/slave manifest example forJMETER (note that it's not using the side-car container pattern)

While this is viable and possible a working solution, assuming you are looking at the CPU/Memory metrics, you could also leverage the Prometheus stack with the node-exporter
https://github.com/helm/charts/tree/master/stable/prometheus-operator
This could remove the need for your JMETER setup if you are not allowing for specific Jmeter metrics
