Metric encoding is broken when using --enable-gzip-encoding flag.

[AlexShemeshWix]

What happened: Ive enabled gzip compression for kube-state-metrics using extraArgs param in helm chatr (--enable-gzip-encoding)

What you expected to happen: i expect metrics to be compressed but accessible

How to reproduce it (as minimally and precisely as possible): Deploy latest kube-state-metrics chart 2.11.0 with extraAgrs that contains --enable-gzip-encoding param. Wait till kube-state-metrics pod starts. Try to access metrics using any browser. It will fail with "Failed to load resource: net::ERR_CONTENT_DECODING_FAILED" message in console.

Anything else we need to know?:

Environment:

• kube-state-metrics version: v1.9.7
• Kubernetes version (use kubectl version): v1.17.13
• Cloud provider or hardware configuration: AWS
• Other info:

It looks like the curl command can be accessed successfully, but the browser or Prometheus access fails.

I will try to find the cause of the problem.
