升级rancher出现错误

从2.4.7 升级到2.4.8 出现如下错误

./helm upgrade rancher rancher-latest/rancher --namespace cattle-system  --set hostname=rancher.daodao.com
Error: UPGRADE FAILED: unable to recognize "": no matches for kind "Issuer" in version "certmanager.k8s.io/v1alpha1"

按文档用如下方法解决

./helm get values rancher -n cattle-system
USER-SUPPLIED VALUES:
hostname: rancher.daodao.com
ingress:
  tls:
    source: secret

./helm upgrade rancher rancher-latest/rancher --namespace cattle-system  --set hostname=rancher.daodao.com --set  ingress.tls.source=secret
