# VMPodScrape
|
|
|
|
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](./vmagent.md) configuration with
|
|
[kubernetes service discovery](https://docs.victoriametrics.com/sd_configs.html#kubernetes_sd_configs) 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:
|
|
|
|
```yaml
|
|
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](./vmagent.md#scraping).
|
|
|
|
## Specification
|
|
|
|
You can see the full actual specification of the `VMPodScrape` resource in
|
|
the **[API docs -> VMPodScrape](../api.md#vmpodscrape)**.
|
|
|
|
Also, you can check out the [examples](#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](../migration.md).
|
|
|
|
## Examples
|
|
|
|
```yaml
|
|
apiVersion: operator.victoriametrics.com/v1beta1
|
|
kind: VMPodScrape
|
|
metadata:
|
|
name: example-pod-scrape
|
|
spec:
|
|
podMetricsEndpoints:
|
|
- port: web
|
|
scheme: http
|
|
selector:
|
|
matchLabels:
|
|
owner: dev
|
|
```
