Error: rendered manifests contain a resource that already exists. Unable to continue with install: CustomResourceDefinition

[V4A001]

Not working for unclear reason to me:
# Helm v3+ helm install \ cert-manager jetstack/cert-manager \ --namespace cert-manager \ --version v1.1.0 \ --set installCRDs=true

Error: rendered manifests contain a resource that already exists. Unable to continue with install: CustomResourceDefinition "certificaterequests.cert-manager.io" in namespace "" exists and cannot be imported into the current release: invalid ownership metadata; label validation error: missing key "app.kubernetes.io/managed-by": must be set to "Helm"; annotation validation error: missing key "meta.helm.sh/release-name": must be set to "cert-manager"; annotation validation error: missing key "meta.helm.sh/release-namespace": must be set to "cert-manager"

I got the same issue. Could you resolve it @V4A001 ?

run "kubectl api-resources"

[V4A001]

Try this, see if crd 's are installed:
kubectl get crd
If not, install this:
kubectl apply --validate=false -f https://github.com/jetstack/cert-manager/releases/download/v1.1.0/cert-manager.crds.yaml

then run without --set installCRDs=true and version:
helm install cert-manager jetstack/cert-manager --namespace cert-manager --version v1.1.0

It seems you installed it with installCRDs=false before, due to limitations on Helm you can not change this option between upgrades.

ok, thanks for the info, is there an alternative to enable it ?

I faced with the same issue while upgrading helm chart of cert-manager from v0.1 to v1.8

delete all the old crd's
install the latest crd's
I customized values.yaml and have set installCRDs value to false in the values.yaml

steps I followed after deleting old crd's

  - helm repo add jetstack https://charts.jetstack.io
  - helm repo update
  - kubectl apply -f https://github.com/cert-manager/cert-manager/releases/download/v1.8.0/cert-manager.crds.yaml
  - helm upgrade --install cert-manager jetstack/cert-manager --namespace cert-manager --version v1.8.0 -f manifests/cert-manager-values.yaml
