cert-manager-webhook-arvancloud

cert-manager-webhook-arvancloud

A cert-manager dns01 challenge solver for Arvancloud.

This webhook enables you to use Arvancloud DNS for DNS01 challenge validation when issuing certificates with cert-manager.

Installation

Prerequisites

• Kubernetes cluster
• cert-manager installed
• Arvancloud APIKey with Access Policy to the required domains

Installing the Webhook

You can deploy the webhook using the provided Helm chart:

helm repo add arvancloud-webhook https://mohammad-abbasi.me/cert-manager-webhook-arvancloud
helm install cert-manager-webhook-arvancloud arvancloud-webhook/cert-manager-webhook-arvancloud -n cert-manager

Or deploy manually using the manifests in the charts/ directory.

Configuration

Creating a Secret with Arvancloud API Key

Create a Secret in the cert-manager namespace containing your Arvancloud API key:

kubectl create secret generic arvancloud-api-key \
  --namespace cert-manager \
  --from-literal=apikey="your-arvancloud-api-key-here"

Or you can create the Secret using a YAML manifest:

apiVersion: v1
kind: Secret
metadata:
    name: arvancloud-api-key
    namespace: cert-manager
stringData:
  apikey: "apikey xxxxxxxx.xxxxxxxxxxx.xxxxxx"

Creating an Issuer/ClusterIssuer

Create an Issuer or ClusterIssuer resource that uses the Arvancloud webhook for DNS01 validation:

apiVersion: cert-manager.io/v1
kind: ClusterIssuer
metadata:
  name: arvancloud-issuer
spec:
  acme:
    server: https://acme-staging-v02.api.letsencrypt.org/directory
    email: [email protected]
    privateKeySecretRef:
      name: arvancloud-issuer-key
    solvers:
    - dns01:
        webhook:
          groupName: acme.arvancloud.ir
          solverName: arvancloud
          config:
            apiKeySecretRef:
              name: arvancloud-api-key
              key: apikey
            # Optional TTL in seconds for DNS records (default: 120)
            ttl: 120

For a production environment, use the production Let’s Encrypt server:

server: https://acme-v02.api.letsencrypt.org/directory

Creating a Certificate

Create a Certificate resource that uses the Issuer/ClusterIssuer:

apiVersion: cert-manager.io/v1
kind: Certificate
metadata:
  name: example-com
  namespace: default
spec:
  secretName: example-com-tls
  issuerRef:
    name: arvancloud-issuer
    kind: ClusterIssuer
  dnsNames:
  - example.com
  - "*.example.com"

Troubleshooting

• Check the logs of the webhook pod:

kubectl logs -n cert-manager -l app=cert-manager-webhook-arvancloud

• Check the status of the Certificate:

kubectl describe certificate example-com

• Ensure your API key has the correct permissions for DNS management in Arvancloud.
