Collection of IT learning resources

Seeing this with v1.5.1 as well. I had to clean up resources manually and then the install worked with these flags:

helm uninstall cert-manager -n cert-manager
kubectl delete roles cert-manager-startupapicheck:create-cert -n cert-manager;
kubectl delete serviceaccount cert-manager-startupapicheck -n cert-manager;
kubectl delete serviceaccount default -n cert-manager;
kubectl delete jobs cert-manager-startupapicheck -n cert-manager;
kubectl delete rolebindings cert-manager-startupapicheck:create-cert -n cert-manager;
Finally:
helm install cert-manager jetstack/cert-manager --namespace cert-manager --create-namespace --version v1.5.1 --set startupapicheck.timeout=5m --set installCRDs=true
