Reinstalling Alpine Linux on a Lighthouse Instance

Start by creating an instance with Debian or your preferred operating system. Log into the instance.

Download the Arch Linux ISO for booting. Although Alpine's boot ISO can be used, the process may not be as seamless, but feel free to experiment with it.

wget https://mirrors.cqu.edu.cn/archlinux/iso/latest/archlinux-2022.02.01-x86_64.iso -O /archlinux.iso

Next, download the Alpine Linux minirootfs.

wget https://mirrors.tuna.tsinghua.edu.cn/alpine/v3.15/releases/x86_64/alpine-minirootfs-3.15.0-x86_64.tar.gz -O /alpine.tar.gz

Add the following entry to /boot/grub/grub.cfg after the default Debian session.

menuentry "Archlinux Live (x86_64)" {
    insmod iso9660
    set isofile=/archlinux.iso
    loopback lo0 ${isofile}
    linux (lo0)/arch/boot/x86_64/vmlinuz-linux img_dev=/dev/vda1 img_loop=${isofile} earlymodules=loop
    initrd (lo0)/arch/boot/x86_64/initramfs-linux.img
}

Now, access your VNC session via the web page and reboot the instance. Select the newly added entry in the Grub menu.

Once inside the Arch Linux boot disc shell, remount /dev/vda1 in read-write mode, clear everything except the boot disc and Alpine Linux minirootfs, mount /dev/vda1 to /mnt, and then extract the minirootfs. We will retain the boot disc as a fallback option to resolve any issues via the new Grub configuration.

mount -o rw,remount /dev/vda1
mv /run/archiso/img_dev/archlinux.iso /tmp/
mv /run/archiso/img_dev/alpine.tar.gz /tmp/
rm -rf /run/archiso/img_dev/*
mount /dev/vda1 /mnt
mv /tmp/archlinux.iso /mnt/
mv /tmp/alpine.tar.gz /mnt/
tar -xf /mnt/alpine.tar.gz -C /mnt

Proceed to chroot into the new environment.

mount -t proc /proc /mnt/proc
mount --rbind --make-rslave /dev /mnt/dev
mount --rbind --make-rslave /sys /mnt/sys
cp -L /etc/resolv.conf /mnt/etc/resolv.conf
chroot /mnt /bin/sh

Configure the Alpine repository.

source /etc/profile
cat > /etc/apk/repositories << EOF
https://mirrors.tuna.tsinghua.edu.cn/alpine/v3.15/main
https://mirrors.tuna.tsinghua.edu.cn/alpine/v3.15/community
EOF

Update the package list, upgrade existing packages, and install the base system.

apk update
apk upgrade
apk add alpine-base

Install Grub, ensuring to set rootfstype=ext4 in the Linux command line to prevent /dev/vda1 mounting issues.

apk add grub-bios
echo 'GRUB_CMDLINE_LINUX="rootfstype=ext4"' >> /etc/default/grub

To avoid unnecessary firmware installations, install linux-firmware-none. We will also install linux-virt.

/boot/grub/grub.cfg is automatically generated, so running grub-mkconfig is unnecessary.

grub-install /dev/vda
apk add linux-firmware-none
apk add linux-virt

Install e2fsprogs for fsck.ext4.

apk add e2fsprogs

Configure fstab.

echo "/dev/vda1 / ext4 defaults 0 1" > /etc/fstab

Set up the network configuration.

cat > /etc/network/interfaces << EOF
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet dhcp
EOF

Configure OpenRC runlevels.

for i in bootmisc hostname hwclock loadkmap loopback modules networking swap sysctl syslog urandom; do
ln -s /etc/init.d/$i /etc/runlevels/boot/
done
for i in devfs dmesg hwdrivers mdev; do
ln -s /etc/init.d/$i /etc/runlevels/sysinit/
done
for i in acpid sshd; do
ln -s /etc/init.d/$i /etc/runlevels/default/
done
for i in killprocs mount-ro savecache; do
ln -s /etc/init.d/$i /etc/runlevels/shutdown/
done

Finally, reset the root password.

passwd

Reboot the instance to enjoy your freshly installed Alpine Linux.
