如何在 Rancher 2.x 中升级 cert-manageer？

helm version

kubectl -n kube-system create serviceaccount tillerkubectl create clusterrolebinding tiller \  --clusterrole=cluster-admin \  --serviceaccount=kube-system:tiller

helm init --service-account tiller

kubectl -n kube-system rollout status deploy/tiller-deploy:

kubectl label namespace cert-manager certmanager.k8s.io/disable-validation=truekubectl apply --validate=false -f https://raw.githubusercontent.com/jetstack/cert-manager/release-0.11/deploy/manifests/00-crds.yamlhelm repo add jetstack https://charts.jetstack.io && helm update

helm install \  --name cert-manager \  --namespace cert-manager \  --version v0.11.0 \  jetstack/cert-managerkubectl get pods --namespace cert-manager

kubectl get ingress \      --all-namespaces \      -o json | \      jq '.items[] | select(.metadata.annotations| to_entries | map(.key)[] | test("certmana

# 首先，根据你的平台下载二进制文件wget -O api-migration https://github.com/jetstack/cert-manager/releases/download/v0.11.0/api-migration-linux# 或者根据Darwinwget -O api-migration https://github.com/jetstack/cert-manager/releases/download/v0.11.0/api-migration-darwin
# 将二进制文件标记为可执行文件，然后对集群运行二进制文件chmod +x api-migration && ./api-migration --kubeconfig /path/to/my/kubeconfig.yaml
# 查看CLI的输出结果并且检查文件中的差异diff ingress.yaml ingress-migrated.yaml
# 最后，review了新的ingress资源之后，应用manifestkubectl apply -f ingress-migrated.yaml --kubeconfig /path/to/my/kubeconfig.yaml
