Setup environment for manual tests

• Create a kubernetes cluster
• Deploy metricbeat as a daemonset + host network

Generating expectation files

In order to support a new Kubernetes releases you'll have to generate new expectation files for this module in _meta/test. For that, start by deploying a new kubernetes cluster on the required Kubernetes version, for example:

kind create cluster --image kindest/node:v1.32.0

After that, you can fetch the proxy metrics from the api:

kubectl proxy

Then you can fetch the metrics from the url provided in the output and save it to a new _meta/test/metrics.x.xx file.

curl 127.0.0.1:8001/metrics > _meta/test/metrics.x.xx

Run the following commands to generate and test the expected files:

cd metricbeat/module/kubernetes/proxy
# generate the expected files
go test ./... --data
# test the expected files
go test ./...
