This is a cert-manager webhook solver for DNSPod.

• cert-manager >= 1.13.0

First, generate SecretId and SecretKey in Cloud API

You can install chart from git repo:

# Firstly add cert-manager-webhook-dnspod charts repository if you haven't do this
helm repo add cert-manager-webhook-dnspod https://imroc.github.io/cert-manager-webhook-dnspod
# Install the latest version.
helm upgrade --install --namespace cert-manager \
  cert-manager-webhook-dnspod cert-manager-webhook-dnspod/cert-manager-webhook-dnspod

Use kubectl apply to install:

kubectl apply -f https://raw.githubusercontent.com/imroc/cert-manager-webhook-dnspod/master/bundle.yaml

Firstly, create a secret that contains TencentCloud account's SecretId and SecretKey:

apiVersion: v1
kind: Secret
metadata:
  name: dnspod-secret
  namespace: cert-manager
type: Opaque
stringData:
  secretId: xxx
  secretKey: xxx

Base64 is not needed in stringData.

Before you can issue a certificate, you need to create a Issuer or ClusterIssuer.

If you use helm and only need a global ClusterIssuer, you can add --set clusterIssuer.enabled=true --set clusterIssuer.secretId=xxx --set clusterIssuer.secretKey=xxx to create the ClusterIssuer.

Create a ClusterIssuer referring the secret:

apiVersion: cert-manager.io/v1
kind: ClusterIssuer
metadata:
  name: dnspod
spec:
  acme:
    email: [email protected]
    privateKeySecretRef:
      name: dnspod-letsencrypt
    server: https://acme-v02.api.letsencrypt.org/directory
    solvers:
      - dns01:
          webhook:
            config:
              secretIdRef:
                key: secretId
                name: dnspod-secret
              secretKeyRef:
                key: secretKey
                name: dnspod-secret
              ttl: 600
              recordLine: ""
            groupName: acme.dnspod.com
            solverName: dnspod

1. secretId and secretKey is the SecretId and SecretKey of your TencentCloud account.
2. groupName is the the groupName that specified in your cert-manager-webhook-dnspod installation, defaults to acme.dnspod.com.
3. solverName must be dnspod.
4. ttl is the optional ttl of dns TXT record that created by webhook.
5. recordLine is the optional recordLine parameter of the dnspod.
6. email is the optional email address. When the domain is about to expire, a notification will be sent to this email address.

You can issue the certificate by creating Certificate that referring the dnspod ClusterIssuer or Issuer:

apiVersion: cert-manager.io/v1
kind: Certificate
metadata:
  name: example-crt
spec:
  secretName: example-crt
  issuerRef:
    name: dnspod
    kind: ClusterIssuer
    group: cert-manager.io
  dnsNames:
    - "example.com"
    - "*.example.com"

Version 1.5.x has the following changes

• Enhanced logging capabilities: Added JSON-structured logging with richer context for easier troubleshooting, and supports custom log levels (default: info).
• Improved security: Store secretId in Secrets instead of Helm values (consistent with secretKey handling).
• Enhanced code maintainability: Refactored codebase by splitting logic into multiple Go files for better organization.
• Optimized Present implementation:
  • Removed redundant DNS SOA queries to resolve zones (The ResolvedZone sent by cert-manager is the zone already queried through SOA).
  • Eliminated domain lookup via DNSPod API (DNSPod API CreateRecord can accepts Domain directly without requiring DomainID).
• Changed default groupName from acme.imroc.cc to acme.dnspod.com.
• Added support for gitHub pages as helm repository.
• Added optional recordLine in Issuer's webhook config for custom DNS record lines.

If you upgrade from 1.4.0 to 1.5.x, and created Issuer or ClusterIssuer manually (clusterIssuer.enabled=false), you need to add secretIdRef to Issuer's webhook config, also add secretId in your corresponding Secret.
