# Configuration
|
|
|
|
Operator configured by env variables, list of it can be found
|
|
on [Variables](./vars.md) page.
|
|
|
|
It defines default configuration options, like images for components, timeouts, features.
|
|
|
|
In addition, the operator has a special startup mode for outputting all variables, their types and default values.
|
|
For instance, with this mode you can know versions of VM components, which are used by default:
|
|
|
|
```sh
|
|
./operator --printDefaults
|
|
|
|
# This application is configured via the environment. The following environment variables can be used:
|
|
#
|
|
# KEY TYPE DEFAULT REQUIRED DESCRIPTION
|
|
# VM_USECUSTOMCONFIGRELOADER True or False false
|
|
# VM_CUSTOMCONFIGRELOADERIMAGE String victoriametrics/operator:config-reloader-v0.32.0
|
|
# VM_VMALERTDEFAULT_IMAGE String victoriametrics/vmalert
|
|
# VM_VMALERTDEFAULT_VERSION String v1.93.3
|
|
# VM_VMALERTDEFAULT_USEDEFAULTRESOURCES True or False true
|
|
# VM_VMALERTDEFAULT_RESOURCE_LIMIT_MEM String 500Mi
|
|
# VM_VMALERTDEFAULT_RESOURCE_LIMIT_CPU String 200m
|
|
# ...
|
|
```
|
|
|
|
You can choose output format for variables with `--printFormat` flag, possible values: `json`, `yaml`, `list` and `table` (default):
|
|
|
|
```sh
|
|
.operator --printDefaults --printFormat=json
|
|
|
|
# {
|
|
# 'VM_USECUSTOMCONFIGRELOADER': 'false',
|
|
# 'VM_CUSTOMCONFIGRELOADERIMAGE': 'victoriametrics/operator:config-reloader-v0.32.0',
|
|
# 'VM_VMALERTDEFAULT_IMAGE': 'victoriametrics/vmalert',
|
|
# 'VM_VMALERTDEFAULT_VERSION': 'v1.93.3',
|
|
# ...
|
|
# 'VM_FORCERESYNCINTERVAL': '60s',
|
|
# 'VM_ENABLESTRICTSECURITY': 'true'
|
|
# }
|
|
```

## Conversion of prometheus-operator objects
|
|
|
|
You can read detailed instructions about configuring prometheus-objects conversion in [this document](./migration.md).
|
|
|
|
## Helm-charts
|
|
|
|
In [helm-charts](https://github.com/VictoriaMetrics/helm-charts) some important configuration parameters are implemented as separate flags in `values.yaml`:
|
|
|
|
### victoria-metrics-k8s-stack
|
|
|
|
For possible values refer to [parameters](https://github.com/VictoriaMetrics/helm-charts/tree/master/charts/victoria-metrics-k8s-stack#parameters).
|
|
|
|
Also, checkout [here possible ENV variables](./vars.md) to configure operator behaviour.
|
|
ENV variables can be set in the `victoria-metrics-operator.env` section.
|
|
|
|

|

```
|
|
|
|
## Namespaced mode
|
|
|
|
By default, the operator will watch all namespaces, but it can be configured to watch only specific namespace or multiple namespaces.
|
|
|
|
If you want to override this behavior, specify the namespace:
|
|
|
|
- in the `WATCH_NAMESPACE` environment variable.
|
|
- in the `watchNamespace` field in the `values.yaml` file of helm-charts.
|
|
|
|
The operator supports comma separated namespace names for this setting.
|
|
|
|
If namespaced mode is enabled, operator uses a limited set of features:
|
|
- it cannot make any cluster wide API calls.
|
|
- it cannot assign rbac permissions for `vmagent`. It must be done manually via serviceAccount for vmagent.
|
|
- it ignores namespaceSelector fields at CRD objects and uses `WATCH_NAMESPACE` value for object matching.
|
|
|
|
At each namespace operator must have a set of required permissions, an example can be found at [this file](https://github.com/VictoriaMetrics/operator/blob/master/config/examples/operator_rbac_for_single_namespace.yaml).
|
|
|
|
## Monitoring of cluster components
|
|
|
|
By default, operator creates [VMServiceScrape](./resources/vmservicescrape.md)
|
|
object for each component that it manages.
|
|
|
|
You can disable this behaviour with `VM_DASABLESELFSERVICASCRAPECREATION` environment variable:
|
|
|
|
```shell
|
|
VM_DASABLESELFSERVICASCRAPECREATION=false
|
|
```
|
|
|
|
Also, you can override default configuration for self-scraping with `ServiceScrapeSpec` field in each deployable resource
|
|
(`vmcluster/select`, `vmcluster/insert`, `vmcluster/storage`, `vmagent`, `vmalert`, `vmalertmanager`, `vmauth`, `vmsingle`):
|
|
|
|
## CRD Validation
|
|
|
|
Operator supports validation admission webhook [docs](https://kubernetes.io/docs/reference/access-authn-authz/extensible-admission-controllers/)
|
|
|
|
It checks resources configuration and returns errors to caller before resource will be created at kubernetes api.
|
|
This should reduce errors and simplify debugging.
|
|
|
|
Validation hooks at operator side must be enabled with flags:
|
|
|
|
```sh
|
|
./operator
|
|
--webhook.enable
|
|
# optional configuration for certDir and tls names.
|
|
--webhook.certDir=/tmp/k8s-webhook-server/serving-certs/
|
|
--webhook.keyName=tls.key
|
|
--webhook.certName=tls.crt
|
|
```
|
|
|
|
You have to mount correct certificates at give directory.
|
|
It can be simplified with cert-manager and kustomize command:
|
|
|
|
```sh
|
|
kustomize build config/deployments/webhook/
|
|
```
|
|
|
|
### Requirements
|
|
|
|
- Valid certificate with key must be provided to operator
|
|
- Valid CABundle must be added to the `ValidatingWebhookConfiguration`
|
|
|
