Hey Berin,

 

I’m not sure if this completely answers the question, but the helm lookup function (https://helm.sh/docs/chart_template_guide/functions_and_pipelines/)  may be usable here to introspect the secret and make sure it has the correct type or the correct keys in the data.

Subject: Re: [cncf-helm] Is there any way to enforce constraints

 

It appears this did not garner any attention.  Is there any way to enforce constraints on a chart's dependencies?

 

For example, I would like to have my chart enforce a specific _type_ of secret the consumer provides.

 

My container can use TLS secrets and make use of them if they are provided.  However, it won't make sense if the user supplies a service account token or basic-auth token.  It would be fine if the secret is not provided at all, but if it is provided it should be a specific type.

 

I am clear on how to create the templates, and mount the secret to my container.  I'm not clear on how to enforce rather important constraints like that.

Example: I am creating a chart for a single page app server.  In it I want the ability to add a reference to the TLS secret.  The TLS secret would be provided by the person using the chart.

 

In my chart I want to enforce that the provided Secret is the type:  kubernetes.io/tls 

 

I want that constraint enforced prior to deploying the chart.
