[Gotemplate] Is it possible to add conditional template in applicationset?

[shamonshan]

Is it possible to have conditonal rendering of templates in application set ??

something like this

template:
  {{$url := "" }}
  {{$type := "fc"}}
  {{ if eq $type "fc"}}
  {{$url = "fc.com"}}
  {{end}}
    metadata:
      name: '{{.name}}'
    spec:
      project: '{{.configs.project}}'
      destination:
        name: in-cluster
        namespace: '{{.namespace}}'
      source:
        repoURL: '{{$url}}'
        path : helm
        targetRevision: '{{.version}}'

For me the above will return unmarshell errors

It is possible, but the exact way to accomplish it depends on the use case.

You can use Sprig's default functions within a single field.

You can use go text template's conditional blocks as in your example above, as long as those conditions reside within a single field.

Or if you need to do more complex transformations, you can use the templatePatch field introduced in 2.10.

@Coder63 Why are you using backticks instead of regular single quotes?

We use so helm templating so had to add those to get it working but my concern is templatePatch: | & {{- if .git }} , {{- if .helm }}. They don't get evaluated at all.

[crenshaw-dev]

This part doesn't make sense to me:

        {{- if .git }}
        - path: .
          name: `{{ .chart }}`
        {{- end }}
        {{- if .helm }}
        - chart: `{{ .chart }}`
        {{- end }}

First, there shouldn't be a leading - in either if block. You're adding fields to the above source list item, not creating a new list item.

Second, I'm not sure why there's a name field in the git block. I'm pretty sure name isn't a field in the source schema.

@crenshaw-dev / @ChristianCiach: I want to choose between using a Helm repository or a Git repository, depending on a certain condition. I wasn't able to accomplish this with the current examples.

templatePatch: |
  spec:
    {{- if eq .type "git" }}
    sources:
      path: .
    {{- end }}
    {{- if eq .type "helm" }}
    sources:
      chart: `{{ .chart }}`
    {{- end }}

@Coder63 This worked for me, looks like you accidentally specified sources instead of source that would cause the patch to fail.
