<ol>
<li>Download apk-tools-static for your architecture.</li>
<pre>wget https://gitlab.alpinelinux.org/api/v4/projects/5/packages/generic/v2.14.0/x86_64/apk.static</pre>

<li>Unpack .apk</li>

</ol>

=== Install ===

Assuming your alpine rootfs is mounted in '''/tmp/target'''

<code>sudo ./sbin/apk.static --arch $(arch) -X http://dl-cdn.alpinelinux.org/alpine/latest-stable/main/ -U --allow-untrusted --root /tmp/target --initdb add alpine-base</code>

* edit /tmp/target/etc/fstab
* edit /tmp/target/etc/inittab
* edit /tmp/target/etc/resolv.conf
* mount proc/sys/dev
<pre>for a in proc sys dev; do mount -o bind /$a /tmp/target/$a; done</pre>
* chroot into your new installation
<pre>chroot /tmp/target /bin/sh</pre>
* setup hostname
<pre>setup-hostname</pre>
* setup network
<pre>setup-interfaces</pre>
* setup repos
<pre>setup-apkrepos -f</pre>
* add a few base packages
<pre>apk update
apk add linux-lts linux-firmware-none acpi mkinitfs</pre>
* add services to boot
<pre>
rc-update add acpid default
rc-update add bootmisc boot
rc-update add crond default
rc-update add devfs sysinit
rc-update add dmesg sysinit
rc-update add hostname boot
rc-update add hwclock boot
rc-update add hwdrivers sysinit
rc-update add killprocs shutdown
rc-update add mdev sysinit
rc-update add modules boot
rc-update add mount-ro shutdown
rc-update add networking boot
rc-update add savecache shutdown
rc-update add seedrng boot
rc-update add swap boot
</pre>

=== Bootloader ===

=== Notes ===
If you have bootstrapped Alpine Linux from an existing system in a different partition and intend to boot into it, you should always include the root filesystem type (rootfstype) in the kernel parameter (bootloader option), since by default kernel does not automatically load any filesystem modules for root partition, unless specified. That way mount will not complain about being unable to mount root partition on /sysroot.

Example bootloader option:

<code>root=UUID=AAAAAAAA-BBBB-CCCC-DDDD-EEEEEEEEEEEE rw rootfstype=ext4 vfat</code>
