Error in installation of Orion broker helm chart #125

Closed KeshavSoni2511 closed 1 year ago

KeshavSoni2511 commented 2 years ago

I am trying to deploy orion broker through helm and I am facing this issue :-

Error: INSTALLATION FAILED: template: orion/templates/test/orion-test.yaml:1:14: executing "orion/templates/test/orion-test.yaml" at <.Values.test.enabled>: nil pointer evaluating interface {}.enabled

The command which I am using to install it is :- sudo helm repo add fiware https://fiware.github.io/helm-charts sudo helm install fiware/orion --generate-name

I wasn't facing this issue earlier. Can you please help me to resolve it?

Thanks & Regards, Keshav

Hi Keshav,

I just faced the same issue as you. This occurs because the .Values tree is populated based on the input provided through values.yaml, --values, --set, etc. It is not populated based on how the templates consume the input. If a value is not set, .Values has no knowledge of this sub-tree, and therefore it is evaluated as a nil object when rendered through text/template.

As you can see if you look into orion/templates/test/orion-test.yaml, there is a value which is not found on orion/values.yaml, the one triggering your error: <.Values.test.enabled>. To solve this the maintainer should add the value into the chart, until that happens the workaround is to deploy orion broker with the helm sources locally, adding the value manually.

  1. Clone this repository, edit the file orion/values.yaml and add this at the end of the file (you can change it to false):

    test:
enabled: true

  2. Install the helm chart (from helm-charts/charts):

    helm install orion-chart orion/ --values orion/values.yaml

  3. After this the orion broker should be deployed and running:

Hello, sorry, I forgot to set the default-value. Its fixed in the new 1.0.10 chart. Thanks @lopdan for pointing out a solution. Best
