Following this tutorial for ingress and ssl setup. https://www.digitalocean.com/community/tutorials/how-to-set-up-an-nginx-ingress-on-digitalocean-kubernetes-using-helm
Everything going good, installed the cert manager but getting an error applying the cert issuer
kubectl apply -f production_issuer.yaml
Error from server (InternalError): error when creating “kube/issuer.yaml”: Internal error occurred: failed calling webhook “webhook.cert-manager.io”: failed to call webhook: Post “https://cert-manager-webhook.cert-manager.svc:443/mutate?timeout=10s”: x509: certificate signed by unknown authority

Looks like the ca-injector failed to start.
E1106 23:15:28.823721 1 start.go:170] cert-manager/ca-injector “msg”=“Error registering certificate based controllers. Retrying after 5 seconds.” “error”=“no matches for kind "MutatingWebhookConfiguration" in version "admissionregistration.k8s.io/v1beta1"”
Error: error registering secret controller: no matches for kind “MutatingWebhookConfiguration” in version “admissionregistration.k8s.io/v1beta1”
That api does not exist
I took the --version off the cert-manager options. Assuming this installs the latest version of the chart. After that the issuer was able to be applied. Think that step in the tutorial needs to be updated.
