Cannot create dns ClusterIssuer with DigitalOcean provider

[jakubknejzlik]

Describe the bug:

While creating ClusterIssuer with this config:

apiVersion: certmanager.k8s.io/v1alpha1
kind: ClusterIssuer
metadata:
  name: letsencrypt
spec:
  acme:
    server: https://acme-v02.api.letsencrypt.org/directory
    email: 'jakub.knejzlik@gmail.com'
    privateKeySecretRef:
      name: letsencrypt
    dns01:
      providers:
        - name: dns
          digitalocean:
            tokenSecretRef:
              name: digitalocean-dns
              key: access-token

....

kubectl create secret generic digitalocean-dns -n=kube-system --from-file=access-token
kubectl create -f cluster-issuer.yml

cert-manager logs:

The same ClusterIssuer works ok with route53 provider.

Expected behaviour:
Creating ClusterIssuer should work.

Steps to reproduce the bug:

1. install cert-manager 0.5.2
2. create DO secret
3. create ClusterIssuer

Anything else we need to know?:

no

Environment details::

• Kubernetes version (e.g. v1.10.2): 1.11.4
• Cloud-provider/provisioner (e.g. GKE, kops AWS, etc): scaleway
• cert-manager version (e.g. v0.4.0): 0.5.2
• Install method (e.g. helm or static manifests): helm (pharos-cluster)

I think cert-manager version 0.5.2 doesn't support DigitalOcean. I had the same issue but upgrading to the latest dev version (using the with-rbac.yaml file from here) fixed it for me.

Ah, I thought I saw it in release notes, but maybe I misread the information.

@danielslee You are correct. It was already merged, but not released yet. Any plans for the release? :)
