Support crossplane function pull from local docker registry

[markphillips100]

What problem are you facing?

I'm using KCL via a kcl-function provider and have recently had success using crossplane beta render via the crossplane cli for rendering function output locally. The cli talks to a local kcl function service that is able to pull an oci package from my local docker registry using a non-ssl connection.

I want to be able to use my local docker registry in a similar setup from my local KinD cluster where I have crossplane installed. I have a feeling the annotations are only supported by the cli though so is there a way to have the crossplane controller talk to the local kcl function in the same way the cli does so that a non-ssl local docker registry can be used?

How could Crossplane help solve your problem?

Support the crossplane controller access to a locally (on the host) running function so that a local crossplane/function innerloop is possible.

Just to add, I did try using oci://host.docker.internal:7900/.... from the composition's kcl function to see if it would pull but this complains due to the lack of SSL.

This is the error from describing the composite:

Get "https://host.docker.internal:7900/v2/tuckerbox/country-composition-kcl/tags/list": http: server gave HTTP response to HTTPS client

Closing as I believe this is an issue for kcl function rather than crossplane specifically.
