For offline use and performance reasons, minikube caches required Docker images onto the local file system. Developers may find it useful to add their own images to this cache for local development.
Adding an image
To add the ubuntu 16.04 image to minikube’s image cache:
minikube cache add ubuntu:16.04
The add command will store the requested image to
$MINIKUBE_HOME/cache/images, and load it into the VM’s container runtime environment next time
minikube start is called.
To display images you have added to the cache:
minikube cache list
This listing will not include the images which are built-in to minikube.
Deleting an image
minikube cache delete <image name>
