Cert-manager and Rancher 2.0?

the ingress shim I think is buggy or something… here’s a sample issuer config

kind: ClusterIssuer
metadata:
  name: letsencrypt
spec:
  acme:
    # The ACME production api URL
    server: https://acme-v01.api.letsencrypt.org/directory

    # Email address used for ACME registration
    email: tools@whateveremail.com

    # Name of a secret used to store the ACME account private key
    privateKeySecretRef:
      name: letsencrypt-production

    # Enable the HTTP-01 challenge provider
    http01: {}

and a sample Certificate

apiVersion: certmanager.k8s.io/v1alpha1
kind: Certificate
metadata:
  name: www-something-com
  namespace: namespacetouse
spec:
  secretName: www-something-com-tls
  issuerRef:
    name: letsencrypt
    kind: ClusterIssuer
  commonName: thedomain
  dnsNames:
  - thedomain
  acme:
    config:
    - http01:
        ingressClass: nginx
      domains:
      - thedomain
