ssl - 在 Helm 和 Tiller 之间设置 SSL

Question

我正在按照这些说明在 helm 和 tiller 之间设置 SSL当我 helm-init像这样，我得到一个错误

helm init --tiller-tls --tiller-tls-cert ./tiller.cert.pem --tiller-tls-key ./tiller.key.pem --tiller-tls-verify --tls-ca-cert ca.cert.pem
$HELM_HOME has been configured at /Users/Koustubh/.helm.
Warning: Tiller is already installed in the cluster.
(Use --client-only to suppress this message, or --upgrade to upgrade Tiller to the current version.)
Happy Helming!

当我检查我的 pod 时，我得到

tiller-deploy-6444c7d5bb-chfxw                       0/1       ContainerCreating   0          2h

在描述 pod 之后，我得到了

Warning  FailedMount  7m (x73 over 2h)  kubelet, gke-myservice-default-pool-0198f291-nrl2  Unable to mount volumes for pod "tiller-deploy-6444c7d5bb-chfxw_kube-system(3ebae1df-e790-11e8-98ae-42010a9800f9)": timeout expired waiting for volumes to attach or mount for pod "kube-system"/"tiller-deploy-6444c7d5bb-chfxw". list of unmounted volumes=[tiller-certs]. list of unattached volumes=[tiller-certs default-token-9x886]

如果我尝试删除正在运行的 tiller像这样的 pods ，它只是卡住了
helm reset --debug --force


我该如何解决这个问题？ --upgrade flag与 helm init ，但这也不起作用。

我遇到了这个问题，但通过删除 Helm 柄部署和服务并重新初始化来解决。

我也在使用 RBAC，所以也添加了这些命令:

# Remove existing tiller:
kubectl delete deployment tiller-deploy -n kube-system
kubectl delete service tiller-deploy -n kube-system

# Re-init with your certs 
helm init --tiller-tls --tiller-tls-cert ./tiller.cert.pem --tiller-tls-key ./tiller.key.pem --tiller-tls-verify --tls-ca-cert ca.cert.pem
# Add RBAC service account and role
kubectl create serviceaccount --namespace kube-system tiller
kubectl create clusterrolebinding tiller-cluster-rule --clusterrole=cluster-admin --serviceaccount=kube-system:tiller
kubectl patch deploy --namespace kube-system tiller-deploy -p '{"spec":{"template":{"spec":{"serviceAccount":"tiller"}}}}'
# Re-initialize
helm init --service-account tiller --upgrade
# Test the pod is up
kubectl get pods -n kube-system

NAME                             READY     STATUS    RESTARTS   AGE
tiller-deploy-69775bbbc7-c42wp   1/1       Running   0          5m

# Copy the certs to `~/.helm`
cp tiller.cert.pem ~/.helm/cert.pem
cp tiller.key.pem ~/.helm/key.pem

验证 helm 仅通过 tls 响应

$ helm version
Client: &version.Version{SemVer:"v2.10.0", GitCommit:"9ad53aac42165a5fadc6c87be0dea6b115f93090", GitTreeState:"clean"}
Error: cannot connect to Tiller
$ helm version --tls
Client: &version.Version{SemVer:"v2.10.0", GitCommit:"9ad53aac42165a5fadc6c87be0dea6b115f93090", GitTreeState:"clean"}
Server: &version.Version{SemVer:"v2.10.0", GitCommit:"9ad53aac42165a5fadc6c87be0dea6b115f93090", GitTreeState:"clean"}
