| This document explains how to build a custom ISO image using the alpine-iso scripts.
| |
|
| |
|
| First make sure we have the needed tools
| | == ISO remastering == |
| {{Cmd|apk add alpine-sdk}}
| |
|
| |
|
| Then we clone (or update) the alpine-iso git repository.
| | There are third party scripts to re-build completely custom images, like |
| {{Cmd|git clone git://git.alpinelinux.org/alpine-iso}}
| | * [https://github.com/alpinelinux/alpine-make-vm-image alpine-make-vm-image] |
| | (works to only make a disk based VM image) |
|
| |
|
| The alpine-iso scripts is a simple makefile which you need to feed with a ''<name>.conf.mk'' file and a ''<name>.packages''.
| | and there is Alpine's original |
| | * [[How_to_make_a_custom_ISO_image_with_mkimage|mkimg]]. |
| | (creates a diskless ISO file - usually what you want for QEMU and Proxmox) |
|
| |
|
| In the ''<name>.conf.mk'' we specify
| |
|
| |
|
| ;ALPINE_NAME
| |
| :name of iso image
| |
|
| |
|
| ;ALPINE_VERSION
| | == An alternative == |
| :(optional) version string. Will default to todays date.
| |
|
| |
|
| ;KERNEL_FLAVOR
| | It's also possible to commit and load ISO image customizations to and from a writable partition when booting in [[Installation#Diskless_Mode|Diskless Mode]]. |
| :(opional) either ''grsec'', ''vserver'' or ''pae''. Will default to grsec.
| |
|
| |
|
| ;MODLOOP_EXTRA
| |
| :(optional) Extra kernel module packages for the modloop image. For example: ''dahdi-linux-vserver''
| |
|
| |
|
| The ''<name>.packages'' is just a plaintext list of packages that should be included in the iso. You should always add ''alpine-base'' in there or the CD migh not be able to boot. The dependencies for the packages will automatically be pulled in.
| |
|
| |
|
| == A rescue CD example == | | == Booting an ISO image with local customizations == |
| As an example, let us make a rescue ISO with packages needed for rescue operations. We call it ''alpine-rescue''
| |
|
| |
|
| We create the alpine-rescue.conf.mk as follows:
| | * [[Directly booting an ISO file]] |
| ALPINE_NAME := alpine-rescue
| |
| KERNEL_FLAVOR := grsec
| |
| MODLOOP_EXTRA :=
| |
|
| |
|
| And then the ''alpine-rescue.packages'' as:
| | [[Category:Package Manager]] |
| alpine-base
| | [[Category:ISO]] |
| bkeymaps
| |
| openssh
| |
| e2fsprogs
| |
| mdadm
| |
| lvm2
| |
| parted
| |
| debootstrap
| |
| ntfs-3g
| |
| | |
| {{Tip|If you have home-built apk's that you would like to include in the iso you are about to create:
| |
| Make sure your developer keys are placed in /etc/apk/keys/
| |
| | |
| Learn apk-tools to find your home-built apk's:
| |
| {{Cmd|echo "~/.cache/apks" >> /etc/apk/repositories}}
| |
| }}
| |
| | |
| Make sure the apk index is up to date (so apk finds the packages):
| |
| {{Cmd|apk update}}
| |
| | |
| We create the ISO image by telling the makefile the profile name. The makefile target is ''iso''.
| |
| {{Cmd|<nowiki>make PROFILE=alpine-rescue iso</nowiki>}}
| |
| | |
| To generate the sha1 sum we use the ''sha1'' make target.
| |
| {{Cmd|<nowiki>make PROFILE=alpine-rescue sha1</nowiki>}}
