Helm 3 chart install error: error validating data: apiVersion not set

I have a simple helm chart that will deploy an application to my local copy of kubernetes via docker desktop. If I use kubectl to deploy the yaml one file at a time things work correctly. However, when I try to create a helm chart for easier deployments I get the following error.

helm install demo WebApi

Error: unable to build kubernetes objects from release manifest: error validating "": error validating data: apiVersion not set

The error seems to be saying that I am missing an apiVersion map in one or more of my YAML files. However, all of my files have what seems to be the correct apiVersions.

As you can see all of my YAML files have the required apiVersion map however the error still says they are missing. What corrections do I need to make in order for this to work as intended?

Solution

  • Error: unable to build kubernetes objects from release manifest: error validating "": error validating data: apiVersion not set

    This error means that the installation command was executed from wrong directory or wrong path to chart has been provided.

    In order to install it, you have to either execute from the directory where Chart.yaml is placed or provide the path to this directory as an argument in helm install command, example from WebApi directory:

    helm install webapi .
