I put Alpine Linux in Larkbox and made it my home server


INDIGOGO crowdfunding CHUWI LarkBox . A very small PC with a housing size of 61x61x43 (H) mm and a weight of 127 g. Windows 10 Home is pre-installed. The specifications are as follows.

Device Spec
CPU Intel Celeron J4115
storage 128GB eMMC
Wi-Fi 802.11a/ac/b/g/n
Bluetooth 5.1

In addition, there is a 2242 size SATA SSD slot, which can be expanded up to 2TB. It is sold on the mail order site at a price of about 20,000 yen. The investment amount of crowdfunding was about 16,000 yen, so it's a little profitable.

If you search for "NUC" on Amazon, you will find a mountain of tiny PCs with a concept similar to LarkBox. If you want to get it cheaply by crowdfunding, as of 2020/9, INDIGOGO is soliciting GMK NucBox , so why not apply?

LarkBox is a poor spec to use as a Windows PC, so put Alpine Linux and use it as your home server. Since it has a TDP of 10W, it generates very little heat and consumes power, so I think it is suitable for servers. However, since there is no wired LAN port, it is fatal as a server. .. .. In the streets, it seems that some people use Raspberry Pi 4 as their home server, and although Raspberry Pi 4 has a wired LAN port, the CPU is powerless and it should be about a file server, but it is true that the web application runs hard I think it's impossible. I would like to confirm how much it can be done with LarkBox.

This article is a reminder of the procedure for putting Alpine Linux in LarkBox.

It's not a very tantalizing shot, but I'll give you a photo. Footprint similar to 4 AA batteries.


Larkbox setup

On my home server, I also want to run Time Capsule for Mac backup, so 128GB of storage is not enough. Therefore, add 1TB M2.SSD. Open the back cover and insert it into the slot. The housing is made of resin, which seems to have low heat dissipation performance, and when the resin back cover is opened, there is a resin inner lid, and the base is inside. SSDs are trapped in a narrow space between the inner lid and the back cover where no air flows, and heat dissipation is quite anxious.

To enter the BIOS, press the power button and then press the escape key repeatedly.

Install Alpine Linux

Download and install the EXTENDED package from the Alpine Linux site . At first, I tried to install the STANDARD package, but the STANDARD package is too minimal to use without even pinging. The 128GB storage is so huge for Alpine Linux that I prefer the EXTENDED package here.

Burn the downloaded ISO file alpine-extended-3.12.0-x86_64.iso to a USB stick and boot from it. Log in as root. (No root password)


Start the installation with. The Alpine Linux installer doesn't look like a major distribution installer. It is necessary to answer the questions one by one interactively.

Windows Home was pre-installed on eMMC, but I removed it without hesitation. I'll put the root and swap here, and put / var (250GB) and / home (750GB) on SSD1TB. I'm thinking of installing only docker directly, and installing necessary apps with docker-compose. Therefore, reserve a large / var used by docker. I think there is an idea that the route should be put in SSD instead of slow eMMC. I thought so, but it didn't change much, so I think eMMC is okay with the route.

The response at the time of installation is as follows.

For the installation, I referred to the following article. https://qiita.com/mo_chiee/items/f539df1bd172f41bc85a Alpine Linux 3.10.3 installation instructions

https://qiita.com/tohka383/items/e7d758a6281fa45e5e16 Docker on Alpine Linux on VirtualBox

After answering all the installation questions, update the package repository.

Modify / etc / apk / repositories as follows


Updated with the following command.

 apk update
 apk upgrade

Insert Docker

 apk add docker docker-compose
 service docker start
 rc-update add docker boot

Allow sudo

 apk add sudo
 %wheel ALL=(ALL) ALL


%wheel ALL=(ALL) ALL

change to

Add your own login account

 addgroup wheel
# adduser my login account
# adduser my login account wheel
# adduser login account docker

Power off once


It's not shutdown.

Remove the USB memory and change the BIOS settings to boot from the eMMC. When I boot, oh, the network isn't connected! Did I have to persist the settings immediately after installation?

Continued installation

network settings

The first series of installations was done with the setup-alpine script, but there is a setup-xxxx script that installs only the individual items. Of the installation script, the network settings part


Connect to Wifi again.

Which one do you want to initialize?: wlan0
Type the wireless network name to connect to: *******
Type the "*******" network Pre-Shared Key: *******
Ip address for wlan0: 192.168.1.xx

Don't forget to make the connection persistent.

 rc-update add wpa_supplicant boot

Disk settings

In the initial installation, I partitioned the root and swap into the eMMC and installed the system, but the added 1TB SSD remains untouched. So, next, enable 1TB SSD.


I want to set / var (250GB) and / home (750GB) to be placed on SSD1TB, but the setup-disk script seems to cut only one partition.

Available disks are:
  sda   (1024.2 GB ATA      NT-1TB-TM       )
Which disk(s) would you like to use? (or '?' for help or 'none') [sda]
How would you like to use it? ('sys', 'data', 'lvm' or '?' for help) [?] data

Looking at what happened to the disc with this,

 df -h
Filesystem                Size      Used Available Use% Mounted on

/ Var was created on SSD1TB (sda). Delete the / var partition and create / var (250GB) and / home (750GB) again.

Get partitioning tool

 apk add -U gptfdisk sgdisk
 gdisk /dev/sda

To repartition sda. The usage of gdisk is the same as fdisk.

System installation complete.

Package installation

Only docker, nginx, and samba are installed directly. nginx is used as a reverse proxy that bundles multiple web applications. If you run samba with docker, fine credential control is complicated, so insert it directly.

docker is already installed when the system is installed.

Start nginx.

 rc-update add nginx

Web app installation

Web apps you want to put in are docker-compose from one end.

For the time being, try installing apache and docker management tool Portainer.


I have set apache to access on port 8080, but I can access it on port 80 via the nginx reverse proxy. When accessing the server in the home LAN from the iPhone, the hosts file cannot be set on the iPhone, so the name must be resolved by the proxy server. Therefore, apache also has a proxy server function. The proxy port number was 8888.

What is the essential performance as a server?

Before the introduction of Larkbox, the server was CentOS 7 (memory 8GB) on VirtualBox on Windows Pro on Nuc (memory 32GB) of Core i7-8559U, but there is not much change in experience. Impression that it can be used reasonably though it is a server without a wired LAN.

I also tried it with a shit heavy app. I installed Fess13 and crawled it, but just displaying the top page of Fess13 is crappy. But that doesn't mean it doesn't work. I was able to crawl.

The heat dissipation that I was worried about seems to be okay.

A good server is ready.
