Hello @fffffreedom ,
If you want to create a new instance with yourmirror you can use :

minikube start --registry-mirror="http://yourmirror"

if your VM instance is already created, you can't update registry-mirror through minikube cli, but you can modify it manually inside your VM (though not recommended) :

1. Connect to the VM using root : minikube ssh su - root (password: root)

2. Edit this file /usr/lib/systemd/system/docker.service using vi or editor to change the starting command :
   ExecStart=/usr/bin/dockerd -H tcp://0.0.0. ...... --registry-mirror http://newregistry

3. save the changes, and then minikube stop and minikube start

It's worth noting that "minikube start" can be re-run safely against a VM that has been already created. It should update the configurations properly.

@tstromberg "minikube start" doesn't update the registry-mirror of an existing vm.

maybe we should enhance the documentation with the "non-updatable parameters"

@tstromberg @starbassma starbassma is right, "minikube start" doesn't update the registry-mirror of an existing vm. hoping this will work later, thks

3. save the changes, and then minikube stop and minikube start

This doesn't work for me, as the file /usr/lib/systemd/system/docker.service is restored after restart.

What did work me was to modify the config.json files under ~/.minikube and update the RegistryMirror field, e.g.

~/.minikube/machines/minikube/config.json

           "Labels": null,
           "LogLevel": "",
           "StorageDriver": "",
           "SelinuxEnabled": false,
           "TlsVerify": false,
           "RegistryMirror": [
              "http://newregistry"
            ],
           "InstallURL": ""

Hope it helps.
