Fetch Kubernetes version depending upon the deployment environment and support ingress in all kubernetes version

[Arya_Haldar]

Hi Everyone,
Is there an alternative supported by replicated to get cluster version.
Like helm have .Capabilities bundle to get kubeversion.
semverCompare “>=1.19-0” .Capabilities.KubeVersion.GitVersion

The use case is that, we want to update our ingress manifest depending upon the kubernetes version they are running.

A vague idea of what I have currently done:

---
# repl{{ if semverCompare ">=1.19-0" .Capabilities.KubeVersion.GitVersion }}
apiVersion: networking.k8s.io/v1
# repl{{ else if semverCompare ">=1.14-0" .Capabilities.KubeVersion.GitVersion }}
apiVersion: networking.k8s.io/v1beta1
# repl{{ else }}
apiVersion: extensions/v1beta1
# repl{{end }}
kind: Ingress
metadata:
  name: ingress-name
  annotations:
# repl{{ if semverCompare "<1.18-0" .Capabilities.KubeVersion.GitVersion }}
    kubernetes.io/ingress.class: 'repl{{ ConfigOption "ingress_class_name" }}'
# repl{{ end }}
    kots.io/placeholder: repl{{ printf "'true'" }}repl{{ ConfigOption "ingress_annotations" | nindent 4 }}
spec:
... incomplete example

Thanks in advance for any suggestion or help.

Hi Arya!

Thank you for asking your question.

Unfortunately this is not possible today, but sounds like a great field to add to our Static Context.

The best way to get this in front of our product team is to submit a feature request via the Vendor Portal. This will create a feature request in our internal system and allows our product team to follow up directly with you if they have questions.

One more thing…

When Replicated deploys a Helm Chart it uses the Helm CLI. If you have your ingress defined as a Helm Chart then you should be able to take advantage of .Capabilities.
