Usage inside of cert-manager namespace

[max312]

I am unable to use this with "cert-manager" as namespace.
When inside cert-manager namespace, i get "Unable to handle request" and the webhook-pdns doesn't have any logging?

Also can you clarify some things in the installation process?

1. is it possible to change the namespace?
2. how can i change the "groupname" while using helm?
   3.I think it is easier to supply a "kubectl apply -f". as this is a relatively small addition to cert-manager and you might save helm overhead?

I should work within the cert-manager namespace. I can take a look, but to ensure we're about the same setup - what version of cert-manager and what version of Kubernetes are you using?

For your questions:

1. You can install the webhook into any namespace (helm -n $NAMESPACE install ...). Just make sure the helm values point to the right namesapce for your cert-manager installation (

   cert-manager-webhook-pdns/deploy/cert-manager-webhook-pdns/values.yaml

   Line 11 in 6e0531a

   certManager:

   ).
2. You can override the group name by overriding the default value (

   cert-manager-webhook-pdns/deploy/cert-manager-webhook-pdns/values.yaml

   Line 9 in 6e0531a

   groupName: acme.zacharyseguin.ca

   )
3. This was originally based on the https://github.com/cert-manager/webhook-example which had the helm chart, and due to the customization options, I will continue to only offer the helm chart.

Please let me know if you have any additional questions! Thanks

Hi @zachomedia,

I added your index.yaml using in my own Chart.yaml by doing:

apiVersion: v2
name: cert-manager
version: 1.0.0
dependencies:
  - name: cert-manager
    version: 1.18.2
    repository: https://charts.jetstack.io
  - name: cert-manager-webhook-pdns
    version: 3.2.3
    repository: https://zachomedia.github.io/cert-manager-webhook-pdns

When doing:

helm template charts/cert-manager/ --namespace cert-manager

Helm does not add the namespace definition to the output yaml. When appending "| kubectl create -f -", it creates anything expect the webhook-pdns in the cert-manager namespace.

My workaround is this atm:

helm template charts/cert-manager/ --namespace cert-manager | kubectl create --namespace cert-manager -f -

Is there any way to make the helm template argument work also with this chart? :)

Thanks!

PS: I am very new to Kubernetes and do not yet understand anything.. :D so please excuse if my comment/question might me not that smart..

@netfreak98 Unfortunately, I believe that is a limitation of helm template. I believe the only way to make this work would be to probably add something to the templates that (optionally) adds the namespace to every generated resource in the chart.

Is there a reason for preferring helm template | kubectl create over helm install?
