How to install a CA in Minikube so image pulls are trusted

Question

I want to use Minikube for local development. It needs to access my companies internal docker registry which is signed w/ a 3rd party certificate.

Locally, I would copy the cert and run update-ca-trust extract or update-ca-certificates depending on the OS.

For the Minikube vm, how do I get the cert installed, registered, and the docker daemon restarted so that docker pull will trust the server?

I had to do something similar recently. You should be able to just hop on the machine with minikube ssh and then follow the directions here

https://docs.docker.com/engine/security/certificates/#understanding-the-configuration

to place the CA in the appropriate directory (/etc/docker/certs.d/[registry hostname]/). You shouldn't need to restart the daemon for it to work.
