error converting YAML to JSON: yaml: line 22: did not find expected key about helm HOT 9 OPEN

@Marwen-TAALLAH please format your code by code.

@Marwen-TAALLAH please format your code by code.

Done !

from helm.

@Marwen-TAALLAH is there a step to process the values.yaml file first before passing it to helm, or is the file passed in as-is in the description? If so, I think helm will report an error because that file does not look like valid YAML

master:
  ${ indent(2, redis_affinity) }
  ${ indent(2, redis_nodeSelector) }
  ${ indent(2, redis_default_tolerations) }
  persistence:
    enabled: false

Specifically, the master value is a mixture of a map/dictionary and a scaler (string).

I'm not aware of helm supporting templating for the values file

@banjoh The values.yaml file is causing a problem only when the redis chart is called as a module, when executinf the terraform apply locally, the file doesn't cause an issue !!

from helm.

Are you able to create a reproducer chart, say by creating a chart using helm create foo then adding your values to the default values file? If you are using subcharts, then setup your test accordingly. It will be easier to troubleshoot the issue if terraform and any other external tool is absent.

from helm.

@banjoh I am able to create the chart with helm directly without terraform, I am also able to create the chart with terraform, all of that with the exact same values.yaml I have provided.
The problem occured when I tried to call the terraform code as a module.

from helm.

@Marwen-TAALLAH to rule out terraform as being the problem here, could you provide the helm commands that terraform successfully templates your helm chart with?

I cannot run terraform, so I'm not able to ascertain whether this values file is valid as you say.

Am looking to see the output of helm template <your-chart> --values values.yaml

Helm does not offer direct support for this. Still, it is a frequent practice—otherwise, avoiding the repetition of the same values would often be impossible (or rather, possible, but highly inefficient). However, this issue is a complete mess—mixing Terraform with Helm, and the task does not make any sense. Even my most bizarre 'Helm sadism' (referring to overly complex and overengineered solutions), such as a complete AST parser implemented purely using Go Templates in Helm, would work better than the convoluted solution this person is trying to assemble here (no offense).

@Marwen-TAALLAH I have no idea what ${ ... } means—Terraform? Why isn't it described better? This does not look like a Helm issue... Your generated YAML is corrupted somehow. If it is not valid YAML, you must fix that first...
