How to make a custom ISO image
The easiest way is to use script alpine-make-vm-image.
Live Disk Setup with APKOVL
Once you have customized your custom ISO, you can now setup the live environment to operate outside of the standard installer as follows:
- Generate an APKOVL file with lbu,
- Alpine ISO requires the OVL Volume to be hosted on a web server. Put the APKOVL file on a webserver and identify the url.
- Uncomment the
APKOVLline in the alpine flavor of your choice and set it to the address of your ovl volume.
- Any packages you add to /etc/apk/world of your lbu will automatically be installed onto the live system image.
- If you don't have a web server you can run busybox's httpd temporarily -
busybox httpd -p 127.0.0.1:80
- In general,
lbuwill only handle files in
/etc, to customize this further, you need to add additional files.
- If you want to make a customized installer, you need to create
.default_boot_serviceswhich will cause
mkinitfsto create the defaults for the live image.
Testing your ISO image
Qemu is useful for a quick test of your created ISO image.
