## Prerequisites

* Credentials for `gcr.io/k8s-minikube`
* Docker
* Gcloud

## Background

gvisor support within minikube requires a special Docker image to be generated. After merging changes to `cmd/gvisor` or `pkg/gvisor`, this image will need to be updated.

The image is located at `gcr.io/k8s-minikube/gvisor-addon`

## Why is this image required?

`gvisor` requires changes to the guest VM in order to function. The `addons` feature in minikube does not normally allow for this, so to workaround it, a custom docker image is launched, containing a binary that makes the changes.

## What does the image do?

- Creates log directories
- Downloads and installs the latest stable `gvisor-containerd-shim` release
- Updates the containerd configuration
- Restarts containerd and rpc-statd

## Updating the gvisor image

`make push-gvisor-addon-image`
