Review Comment: I think more content should use the link of APISIX public-api plugin. Or write APISIX use prometheus plgin to expose metrics and integrate with prometheus, but use public-api to enhance its security (for details, you can look at the description in the prometheus plugin documentation first. ########## docs/en/latest/practices/how-to-access-Apache-APISIX-Prometheus-Metrics-on-k8s.md: ########## @@ -0,0 +1,97 @@ +--- +title: How to access Apache APISIX Prometheus metrics on Kubernetes +--- + +<!-- +# +# Licensed to the Apache Software Foundation (ASF) under one or more +# contributor license agreements.
