Issue while installing stash kubernetes 1.11.2

[davidcodesido]

I'm installing stash for the first time on kubernetes 1.11.5 via heml. I'm running the following command:

helm install appscode/stash --version 0.7.0 --name stash-operator --set apiserver.enableValidatingWebhook=true --set apiserver.enableMutatingWebhook=true

and I'm getting the following error:

Error: render error in "stash/templates/validating-webhook.yaml": template: stash/templates/validating-webhook.yaml:21:31: executing "stash/templates/validating-webhook.yaml" at <.Values.apiserver.ca>: wrong type for value; expected string; got interface {}

Any advice?

What is your helm version? What is your onessl version ?

You need to use this command as documented:
https://github.com/appscode/stash/blob/0.7.0/docs/setup/install.md#using-helm

# Kubernetes 1.9.0 or later
$ helm install appscode/stash --name stash-operator --version 0.7.0 \
  --set apiserver.ca="$(onessl get kube-ca)" \
  --set apiserver.enableValidatingWebhook=true \
  --set apiserver.enableMutatingWebhook=true

apiserver.ca is not set, so you are seeing this error.

helm version

Client: &version.Version{SemVer:"v2.9.1", GitCommit:"20adb27c7c5868466912eebdf6664e7390ebe710", GitTreeState:"clean"}
Server: &version.Version{SemVer:"v2.9.1", GitCommit:"20adb27c7c5868466912eebdf6664e7390ebe710", GitTreeState:"clean"}

Not sure what onessl is or how to check the version. I'm relatively new to k8s.

[ Edited ]
I saw one comment in other thread by you and I installed onessl via:

curl -fsSL -o onessl https://github.com/kubepack/onessl/releases/download/0.5.0/onessl-linux-amd64 \
  && chmod +x onessl \
  && sudo mv onessl /usr/local/bin/

onessl version

Version = 0.5.0
VersionStrategy = tag
Os = linux
Arch = amd64
CommitHash = 7e97988ce097da268139a1732b16ba1905c6112d
GitBranch = release-0.5
GitTag = 0.5.0
CommitTimestamp = 2018-06-12T08:22:48

You can find the onessl here: https://github.com/kubepack/onessl/releases

We use this to issue certs for kubernetes operator apps.

After installing onessl the error no longer happens.
