How to make a custom ISO image: Difference between revisions

Revision as of 18:43, 9 May 2020

One way to completely re-build custom images is to use a script like alpine-make-vm-image.

If you want to make a customized installer, you need to create .default_boot_services which will cause mkinitfs to create the defaults for the live image.

An alternative

It's possible to commit and load ISO image customizations to and from disk.

Booting an ISO image with local customizations

From a dedicated boot media, obviously.

+* If you want to make a customized installer, you need to create <code>.default_boot_services</code> which will cause <code>mkinitfs</code> to create the defaults for the live image.
-Once you have booted and customized the system that was booted from an ISO, you may save the state and arrange for the ISO to load the customizations:

-* The "diskless" Alpine ISO images look for an APKOVL Volume in mountpoints below /media/, and may alternatively be pointed to a web server.
-* If you put the APKOVL file on a webserver, you need to supply a customized url with the <code>APKOVL</code> boot parameter.
-Notes:
-* Any packages you add to /etc/apk/world of your lbu will automatically be installed in the live system.
-* See [[Alpine_Linux_package_management#Local_Cache]] about managing included packages.
-* If you don't have a web server you can run busybox's httpd temporarily - <code>busybox httpd -p 127.0.0.1:80</code>
