I have a code-server Alpine 3.12 container that runs correctly, installed with npm :

RUN apk add --no-cache alpine-sdk bash libstdc++ libc6-compat npm libx11-dev libxkbfile-dev libsecret-dev
RUN npm install -g --cache /tmp/npm-cache --unsafe-perm code-server && rm -r /tmp/npm-cache

If that doesn't do the trick the problem runs deeper than dependencies I suppose.

As of 2020, 32-bit builds of Node.js are no longer supported officially, this also means x86 builds is not guranteed compatibility anymore. I'm sad to say, you must use a cloud service to run code-server instead.

try x86 version in the release 3.5.0, that is the last version build with x86

I don't think you need iSH, because, I found another method. Click the link here which will open a YT video. In that, he CHANGES the config. So, if you have Windows, get Debian with Curl in it or if you use Mac or Linux, copy the code-server curl line, put it in the Linux/Mac Terminal, and wait. After it's installed, run code-server. Then, it will show some line for a config file. Open your local VSCode, and locate and then go to the file(if you don't know how to do on WSL, get Remote-WSL extension, and connect to your distro. Then you are ready to go to the file 👍 ). Then, open your terminal and put

ifconfig

Now, find your IP address as of WiFi, and paste it in the config on the bind_addr line, and replace it from 127.0.0.1:8888 to yourip:8888, where yourip is your IP address as of WiFi. Then, put that link on your iPad and you are good to go 👍 :)
