REG.RU provider DNS01 challenge solver

REG.RU API documentation

API documentation https://www.reg.ru/reseller/api2doc#common

REG.RU DNS provider allow access to API from known IP-addresses only

Access configuration https://www.reg.ru/user/account/#/settings/api/

Configure API access from your IP-address or you can see something like this message:

{
   "charset" : "utf-8",
   "error_code" : "ACCESS_DENIED_FROM_IP",
   "error_params" : {
      "command_name" : "zone/get_resource_records"
   },
   "error_text" : "Access to API from this IP denied",
   "messagestore" : null,
   "result" : "error"
}

Creating secret with REG.RU API credentials

Create kubernetes secret with credentials:

kubectl --namespace cert-manager create secret generic regru-api-creds --from-literal=login='<your-username>' --from-literal=password='<your-password>'

One can use any suitable way https://kubernetes.io/docs/tasks/configmap-secret/

Creating your own webhook

Deploy webhook from this repository using helm utility:

git clone https://github.com/daloman/cert-manager-webhook-regru.git

helm --namespace cert-manager upgrade --install regru-webhook ./cert-manager-webhook-regru/deploy/helm/regru-webhook/ --set groupName="acme.regru.ru"

Creating clusterIssuer resource

apiVersion: cert-manager.io/v1
kind: ClusterIssuer
metadata:
  name: regru-dns
spec:
  acme:
    email: username@example.com
    privateKeySecretRef:
      name: letsencrypt-private-key
    server: https://acme-staging-v02.api.letsencrypt.org/directory
    solvers:
    - dns01:
        webhook:
          config:
            apiLoginRef:
              key: login
              name: regru-api-creds
            apiPasswordRef:
              key: password
              name: regru-api-creds
          groupName: acme.regru.ru
          solverName: regru

Running the test suite

All DNS providers must run the DNS01 provider conformance testing suite, else they will have undetermined behaviour when used with cert-manager.

It is essential that you configure and run the test suite when creating a DNS01 webhook.

An example Go test file has been provided in main_test.go.

You can run the test suite with:

$ TEST_ZONE_NAME=example.com. make test

The example file has a number of areas you must fill in and replace with your own options in order for tests to pass.
