if statements works wrong

Question

Here my templates/deployment.yaml snippet code:

volumes:
  - name: notebooks
  {{- if .Values.persistence.enabled }}
    persistentVolumeClaim:
      claimName: "sdfsdf"
  {{- else }}
    emptyDir: {}
  {{- end -}}
  - name: logs
  {{- if .Values.persistence.enabled }}
    persistentVolumeClaim:
      claimName: "sdfsdfdsf"
  {{- else }}
    emptyDir: {}
  {{- end -}}
  - name: conf
  {{- if .Values.persistence.enabled }}
    persistentVolumeClaim:
      claimName: "sdfsdfsdfsdfsd"
  {{- else }}
    emptyDir: {}
  {{- end -}}

Currently, I'm getting:

& helm template zeppelin ./
Error: YAML parse error on zeppelin/templates/deployment.yaml: error converting YAML to JSON: yaml: line 95: block sequence entries are not allowed in this context

It's getting me:

block sequence entries are not allowed in this context

I've tried to clean a bit up the code:

  volumes:
    - name: notebooks
      persistentVolumeClaim:
        claimName: "sdfsdf"
    - name: logs
      persistentVolumeClaim:
        claimName: "sdfsdfdsf"
    - name: conf
      persistentVolumeClaim:
        claimName: "sdfsdfsdfsdfsd"

It's rendered coorectly.

What's wrong on if statements?

Answer 1

You have some extra trims in your if/else statements that break the yaml structure.

Working example:

volumes:
  - name: notebooks
  {{- if .Values.persistence.enabled }}
    persistentVolumeClaim:
      claimName: "sdfsdf"
  {{- else }}
    emptyDir: {}
  {{- end }}
  - name: logs
  {{- if .Values.persistence.enabled }}
    persistentVolumeClaim:
      claimName: "sdfsdfdsf"
  {{- else }}
    emptyDir: {}
  {{- end }}
  - name: conf
  {{- if .Values.persistence.enabled }}
    persistentVolumeClaim:
      claimName: "sdfsdfsdfsdfsd"
  {{- else }}
    emptyDir: {}
  {{- end }}
