Burning an image to a CD or DVD
On systems that ship cdrtools (e.g., Gentoo, openSUSE, NetBSD, Slackware), you can use cdrecord to write an image to a disc. For example:
cdrecord -v speed=4 alpine-standard-3.8.0-x86.iso
If there's only one CD drive on the system, it should be auto-detected. If not, find the device name using lsblk and specify the dev option. For example:
cdrecord -v dev=/dev/sr0 speed=4 alpine-standard-3.8.0-x86.iso
Alpine, like Debian, has cdrskin, which can be invoked just like cdrecord above.

Example:
growisofs -Z /dev/dvd=/path/to/dvdimage.iso
Copying an installation image to a USB key

mkarchisogenerates hybrid ISOs, where, as far as I know,alpine-isodoes not
Creating an image from a CD
To do the converse operation, copying a CD to an ISO image, execute:
dd if=/dev/cdrom of=/path/to/cdimage.iso
Mounting an ISO image
To mount an ISO without physically burning it to a CD:
modprobe loop LOOP=`losetup -f` losetup $LOOP /path/to/cdimage.iso mount -t iso9660 -o ro $LOOP /mnt ... # when finished umount /mnt losetup -d $LOOP # this step may happen automatically when you run umount
