Cache Rules Everything Around Minikube
|
||
|
|
---
|
||
|
|
|
||
|
|
minikube has built-in support for caching downloaded resources into `$MINIKUBE_HOME/cache`. Here are the important file locations:
|
||
|
|
|
||
|
|
* `~/.minikube/cache` - Top-level folder
|
||
|
|
* `~/.minikube/cache/iso` - VM ISO image. Typically updated once per major minikube release.
|
||
|
|
* `~/.minikube/cache/images` - Docker images used by Kubernetes.
|
||
|
|
* `~/.minikube/cache/<version>` - Kubernetes binaries, such as `kubeadm` and `kubelet`
|
||
|
|
|
||
|
|
## Kubernetes image cache
|
||
|
|
|
||
|
|
`minikube start` caches all required Kubernetes images by default. This default may be changed by setting `--cache-images=false`. These images are not displayed by the `minikube cache` command.
|
||
|
|
|
||
|
|
## Arbitrary docker image cache
|
||
|
|
|
||
|
|
See [Tasks: Caching images]({{< ref "/docs/tasks/caching.md" >}})
|
||
|
|
|
||
|
|
## Sharing the minikube cache
|
||
|
|
|
||
|
|
For offline use on other hosts, one can copy the contents of `~/.minikube/cache`. As of the v1.0 release, this directory contains 685MB of data:
|
||
|
|
|
||
|

If any of these files exist, minikube will use copy them into the VM directly rather than pulling them from the internet.
