zrok helm chart : configmap "ziti-controller-ctrl-plane-cas" not found #259

Open 7Kronos opened 1 week ago

Hi,

Thank you for your amazing work !

I am trying to deploy a self zrok instance using the zrok helm chart alone. I explored the repo and found that there is no templates or scripts creating this configMap. Is the zrok helm chart not self-sufficient ?

You're welcome! I'm glad you found it useful.

You've stumbled upon a chart dependency that's less than obvious. I'll take this issue as a prompt to make it easier to figure out from the README.

The zrok chart uses a ConfigMap you provide by name to configure itself to trust the OpenZiti controller's certificate.

If you are self-hosting the OpenZiti controller in the same cluster, you can point the zrok charts values to the ConfigMap provided by the ziti-controller chart. It contains a bundle of root CA certs.

If there's no ziti-controller release in the same cluster, you can compose a configmap that satisfies the zrok chart's requirement. Let me know if you'd prefer that approach, have a ziti-controller release with the trust bundle ConfigMap, or would prefer to bypass cert verification.

e.g., if you DO have a ziti-controller release in your cluster named "myziti1" then the existing trust bundle ConfigMap is named "myziti1-ctrl-plane-cas" and is, by default, propagated to all K8S namespaces. 

helm upgrade --install --set ziti.ca_cert_configmap="myziti1-ctrl-plane-cas"

If, perchance, you customized the ziti-controller value ctrlPlaneCasBundle.namespaceSelector, and the zrok chart is in a different namespace than ziti-controller, then it's also necessary to label the zrok namespace according to your custom namespace selector to trigger the trust bundle ConfigMap propagating to the zrok namespace.

Thanks @qrkourier for your quick anwser !

OK I see, I overlooked the templates, I though zrok helm chart was a combination of "older" charts and include a controller instance. I understand now.

I can deploy a ziti-controller in the same namespace. But by curiousity, how could I create this configMap without the controller generating it ?

Thank you for mentioning the expected names, I will take a close look once the controller is deployed.

Let me know if I can help providing feedback or repo files used for this "minimal" deployment.

If your zrok is in a different cluster than the ziti-controller then you would need create a ConfigMap manifest. The data would have a key=value map where the key is the value of zrok chart input value ziti.ca_cert_file. The default key is ctrl-plane-cas.crt, and its value is a PEM bundle of trusted root certs.

The easiest way would be to copy the manifest from the ziti-controller's cluster to the cluster where zrok is installed, but you can fetch the root CA bundle from any Ziti controller like this.

curl -sSk https://myziti.example.com/.well-known/est/cacerts \
| base64 -d \
| openssl pkcs7 -inform DER -outform PEM -print_certs

Example ConfigMap manifest:

apiVersion: v1
kind: ConfigMap
metadata:
  name: ziti-controller-ctrl-plane-cas
  namespace: myzrokns
data:
  ctrl-plane-cas.crt: |
