| {{Obsolete|alpine-iso is deprecated since Alpine 3.5 in favor of mkimage scripts found in root of aports directory. Check also: [[How to make a custom ISO image with mkimage]].}}
| | The easiest way is to use script [https://github.com/alpinelinux/alpine-make-vm-image alpine-make-vm-image]. |
| | |
| This document explains how to build a custom ISO image using the alpine-iso scripts.
| |
| | |
| == Prerequisite ==
| |
| | |
| First make sure we have the needed tools
| |
| {{Cmd|apk add alpine-sdk xorriso syslinux}}
| |
| | |
| Then create signing keys (-i installs them in /etc/apk/keys which is required for later)
| |
| {{Cmd|abuild-keygen -i -a}}
| |
| | |
| Clone (or update) the [http://git.alpinelinux.org/cgit/alpine-iso.git/ alpine-iso git repository].
| |
| {{Cmd|git clone git://git.alpinelinux.org/alpine-iso}}
| |
| | |
| == Core Configuration ==
| |
| | |
| The alpine-iso scripts is a simple makefile which you need to feed with a ''<name>.conf.mk'' file and a ''<name>.packages''.
| |
| | |
| In the ''<name>.conf.mk'' we specify
| |
| | |
| ;ALPINE_NAME
| |
| :name of iso image
| |
| | |
| ;ALPINE_VERSION
| |
| :(optional) version string. Will default to todays date.
| |
| | |
| ;KERNEL_FLAVOR
| |
| :(optional) 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''
| |
| | |
| ;APK_REPOS
| |
| :(optional) Path to addidtional apk repository.
| |
| | |
| The ''<name>.packages'' is just a plaintext list of packages that should be included in the ISO image. You should always add ''alpine-base'' in there or the CD might not be able to boot. The dependencies for the packages will automatically be pulled in.
| |
| | |
| == A rescue CD example ==
| |
| As an example, let us make a rescue ISO image with packages needed for rescue operations. We call it ''alpine-rescue''
| |
| | |
| We create the ''alpine-rescue.conf.mk'' as follows:
| |
| ALPINE_NAME := alpine-rescue
| |
| KERNEL_FLAVOR := grsec
| |
| MODLOOP_EXTRA :=
| |
| | |
| If you are going to use a custom kernel, don't forget to specify KERNEL_FLAVOR_DEFAULT which will set the default kernel to boot.
| |
| | |
| And then the ''alpine-rescue.packages'' as:
| |
| alpine-base
| |
| bkeymaps
| |
| openssh
| |
| e2fsprogs
| |
| mdadm
| |
| lvm2
| |
| parted
| |
| debootstrap
| |
| ntfs-3g
| |
| | |
| {{Tip| Make sure your public keys are placed in /etc/apk/keys/ (example: root-xxxxxxxx.rsa.pub):
| |
| {{Cmd|ls /etc/apk/keys/}}
| |
| | |
| Learn apk-tools to find your home-built apk's:
| |
| {{Cmd|echo "~/.cache/abuild/" >> /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>}}
| |
| | |
| {{Tip| If you are building inside an LXC guest, use fakeroot:
| |
| {{Cmd|<nowiki>fakeroot make PROFILE=alpine-rescue iso</nowiki>}}
| |
| }}
| |
| | |
| To generate the sha256 sum we use the ''sha256'' make target.
| |
| {{Cmd|<nowiki>make PROFILE=alpine-rescue sha256</nowiki>}}
| |
| | |
| == Package lists ==
| |
| | |
| Beside the plaintext package lists in the git repository, there are more documented package lists contributed by Alpine users. Those lists can be transformed into a plain text description by <code>apk search --exact -v $(cat alpine.packages)</code>.
| |
| | |
| So far the lists below are available (check [[:Category:ISO|here]] for more.)
| |
| | |
| * [[Alpine_mini|Alpine Mini]]
| |
| * [[Alpine_rescue|Alpine Rescue]]
| |
| * [[Alpine_security|Alpine Security]]
| |
| * [[Alpine SCST]]
