cert-manager-webhook-regru's Issues

Cert-manager account cannot create resource regru-dns at the cluster scope

Cluster was obtained using Yandex.Cloud Managed Kubernetes solution.
Any modifications of RBAC roles didn't work.

Are we are missing some APIs / dependencies in our k8s setup (or maybe even our k8s version is not supported)?
Couldn't find any requirements in docs.

We use:

k8s - 1.21.1
webhook - 1.0.0

failed calling webhook "webhook.cert-manager.io"

Hi. i have a cluster, where some time ago been installed, tested and removed cert-manager-webhook-yandex Now i try to install cert-manager-webhook-regru and i'v got error:

client.go:128: [debug] creating 15 resource(s)
Error: INSTALLATION FAILED: Internal error occurred: failed calling webhook "webhook.cert-manager.io": failed to call webhook: Post "https://dev-cert-manager-webhook-yandex-webhook.cert-manager.svc:443/mutate?timeout=10s": service "dev-cert-manager-webhook-yandex-webhook" not found

i'v try to remove all resources with acme|cert-manager names. Clear all CRDs. Make a clean install cert-manager and cert-manager-webhook-regru.
And any way i got this error. Can you help me with debugging?

then you can find it via a query from the official documentation

Hi. Tryed to issue wildcard certificate with manifest:

- apiVersion: cert-manager.io/v1
      kind: Certificate
      metadata:
        name: wildcard-infra-example-com
      spec:
        secretName: wildcard-infra-example-com-secret
        issuerRef:
          name: regru-dns
          kind: ClusterIssuer
        dnsNames:
          - *.infra.example.com

But in pod log see url:
api.reg.ru/api/regru2/zone/add_txt?input_data=%7B%22username%22%3A%22my_regru_user%22%2C%22password%22%3A%22smy_regru_password%22%2C%22domains%22%3A%5B%7B%22dname%22%3A%22%22%7D%5D%2C%22subdomain%22%3A%22_acme-challenge.infra.example.com.%22%2C%22text%22%3A%22CIFuiEULSPsSYQIemqFM0-dAreebSWy-LdWUw_QoMzw%22%2C%22output_content_type%22%3A%22plain%22%7D&input_format=json

And error responce from api:

{
   "answer" : {
      "domains" : [
         {
            "error_code" : "NO_DOMAIN",
            "error_text" : "domain_name not given or empty",
            "result" : "error"
         }
      ]
   },
   "charset" : "utf-8",
   "messagestore" : null,
   "result" : "success"
}

As i understand, from api docs, my url format whong, it shoul be
api.reg.ru/api/regru2/zone/add_txt?input_data=%7B%22username%22%3A%22test%22%2C%22password%22%3A%22test%22%2C%22domains%22%3A%5B%7B%22dname%22%3A%22test.ru%22%7D%2C%7B%22dname%22%3A%22test.com%22%7D%5D%2C%22subdomain%22%3A%22mail%22%2C%22text%22%3A%22testmail%22%2C%22output_content_type%22%3A%22plain%22%7D&input_format=json

rm env zone

the zone can be calculated through requests to api
https://www.reg.ru/reseller/api2doc#zone_nop
you also need to consider dns delegation in _acme-challenge https://letsencrypt.org/docs/challenge-types/
