# CRD Validation
|
||
|
|
|
||
|
|
## Description
|
||
|
|
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.
|
||
|
|
|
||
|
|
## Configuration
|
||
|
|
|
||
|
|
Validation hooks at operator side must be enabled with flags:
|
||
|
|
```
|
||
|
|
--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: `kustomize build config/deployments/webhook/ `
|
||
|
|
|
||
|
|
|
||
|
|
## Requirements
|
||
|
|
|
||
|
|
- Valid certificate with key must be provided to operator
|
||
|
|
- Valid CABundle must be added to the `ValidatingWebhookConfiguration`
