This is similar to https://github.com/prometheus/prometheus/pull/6838 , which will be added in Prometheus v2.21. See https://github.com/prometheus/prometheus/releases/tag/v2.21.0-rc.1 * Added endpointslices discovery to k8s api Started from 1.17 k8s version endpointslices is beta, it allows to query k8s api for endpoints more efficient. It presents at scrape_config.yaml as separate role for kubernetes_sd_config. kubernetes_sd_config: - role: endpointslices * fixed typos, changed EndpointConditions signature - with values instead of pointers
