Filter Kubernetes API by pod name

Question

I have a Kubernetes cluster running in minikube, I want to filter out all Logstash pods via Kubernetes API. Kubernetes API documentation is a bit confusing, I did some research and found out that I can use something like this, but I have been unsuccessful so far:

localhost:8000/api/v1/namespaces/default/pods?labelSelector=logstash

any ideas how to retrieve this? Any help would be really appreciated.

any ideas how to retrieve this?

Since labels are defined in <name>=<value> pairs you need to supply both, as described in the documentation (see the API section)

As an example, supposing you have:

• namepace: default
• labels on pods you want to select:
  • role=ops
  • application=logstash
• kubectl proxy runs on localhost:8000

Then your api call would look like this:

curl localhost:8000/api/v1/namespaces/default/pods?labelSelector=role%3Dops,application%3Dlogstash
