# minikube ISO image
|
|
|
|
This includes the configuration for an alternative bootable ISO image meant to be used in conjunction with minikube.
|
|
|
|
It includes:
|
|
|
|
- systemd as the init system
|
|
- docker
|
|
- CRI-O
|
|
|
|
## Hacking
|
|
|
|
### Requirements
|
|
|
|
* Linux
|
|
|
|
```shell
|
|
sudo apt-get install build-essential gnupg2 p7zip-full git wget cpio python \
|
|
unzip bc gcc-multilib automake libtool locales
|
|
```
|
|
|
|
Either import your private key or generate a sign-only key using `gpg2 --gen-key`.
|
|
Also be sure to have an UTF-8 locale set up in order to build the ISO.
|
|
|
|
### Build instructions
|
|
|
|
```shell
|
|
$ git clone https://github.com/kubernetes/minikube
|
|
$ cd minikube
|
|
$ make buildroot-image
|
|
$ make out/minikube.iso
|
|
```
|
|
|
|
The build will occur inside a docker container. If you want to do this on
|
|
baremetal, replace `make out/minikube.iso` with `IN_DOCKER=1 make out/minikube.iso`.
|
|
The bootable ISO image will be available in `out/minikube.iso`.
|
|
|
|
### Testing local minikube-iso changes
|
|
|
|
```shell
|
|
$ ./out/minikube start \
|
|
--iso-url=file://$GOPATH/src/k8s.io/minikube/out/minikube.iso
|
|
```
|
|
|
|
### Buildroot configuration
|
|
|
|
To change the buildroot configuration, execute:
|
|
|
|
```shell
|
|
$ cd out/buildroot
|
|
$ make menuconfig
|
|
$ make
|
|
```
|
|
|
|
To save any buildroot configuration changes made with `make menuconfig`, execute:
|
|
|
|
```shell
|
|
$ cd out/buildroot
|
|
$ make savedefconfig
|
|
```
|
|
|
|
The changes will be reflected in the `minikube-iso/configs/minikube_defconfig` file.
|
|
|
|
```shell
|
|
$ git status
|
|
## master
|
|
M deploy/iso/minikube-iso/configs/minikube_defconfig
|
|
```
|
|
|
|
### Saving buildroot/kernel configuration changes
|
|
|
|
To make any kernel configuration changes and save them, execute:
|
|
|
|
```shell
|
|
$ make linux-menuconfig
|
|
```
|
|
|
|
This will open the kernel configuration menu, and then save your changes to our
|
|
iso directory after they've been selected.
