The VMPodScrape CRD allows to declaratively define how a dynamic set of pods should be monitored.
Use label selections to match pods for scraping. This allows an organization to introduce conventions
for how metrics should be exposed. Following these conventions new services will be discovered automatically without
need to reconfigure.
VMPodScrape object generates part of VMAgent configuration with
kubernetes service discovery role pod having specific labels and ports.
It has various options for scraping configuration of target (with basic auth,tls access, by specific port name etc.).
A Pod is a collection of one or more containers which can expose Prometheus metrics on a number of ports.
The VMPodScrape object discovers pods and generates the relevant scraping configuration.
The PodMetricsEndpoints section of the VMPodScrapeSpec is used to configure which ports of a pod are going to be
scraped for metrics and with which parameters.
Both VMPodScrapes and discovered targets may belong to any namespace. It is important for cross-namespace monitoring
use cases, e.g. for meta-monitoring. Using the namespaceSelector of the VMPodScrapeSpec one can restrict the
namespaces from which Pods are discovered from. To discover targets in all namespaces the namespaceSelector has to
be empty:
apiVersion: operator.victoriametrics.com/v1beta1
kind: VMPodScrape
metadata:
name: example-pod-scrape
spec:
namespaceSelector:
any: true
More information about selectors you can find in this doc.

You can see the full actual specification of the VMPodScrape resource in
the API docs -> VMPodScrape.
Also, you can check out the examples section.
Migration from Prometheus #
The VMPodScrape CRD from VictoriaMetrics Operator is a drop-in replacement
for the Prometheus PodMonitor from prometheus-operator.
More details about migration from prometheus-operator you can read in this doc.
