DigitalOcean Kubernetes Ingress redirect http->https

Hi,

I just noticed something which is more of a curiosity than anything.

On an ‘ingress’ in DigitalOcean Kubernetes, if the “tls” section is filled out, and a cert-manager annotation is present, there appears to be an automatic http->https redirect happening in the browser.

At this stage, I have not installed cert-manager, nor installed actual TLS certificates. The cert says “Kubernetes Ingress Controller Fake Certificate”.

The point is that I have not set any specific annotations requesting http->https redirects.

That fact that it occurs is surprising.

When I remove all reference to tls and certs, the redirect disappears.

Where is this behavior coming from? Where is it documented and explained?

Perhaps we can imagine that it makes sense to assume you’d want such a redirect, whenever you install TLS certs. Otherwise why are you installing certs.

Thanks.
