insecurity/node-32bit-x87 repository overview

⁠Node 32bit/x87 Docker image

A container to run NodeJS on old architecture.

• Node version: 6.3.1
• Npm version: 3.10.3

⁠Purpose

I have created this docker image in order to build and run the latest Node version on an old 32bit server with athlon CPU (i386/x87: without SSE/SSE2 instructions) ...Fuck Yeah !!!...

Indeed, all other 32bit Node image doesn't work because they use the pre-builded official Node binaries⁠ compiled with standards x86 SSE/SSE2 instructions. When i run them => 'Illegal instruction' => Game over.

⁠Official image 32 bits tweaks

This image is derivated from the official node 6.3.1 image with some tweaks and with the last source code instead of use the pre-builded "Node" binaries:

• https://github.com/nodejs/node⁠
• https://github.com/nodejs/node/blob/master/BUILDING.md⁠

With the following configure options:

./configure --without-snapshot --dest-cpu=ia32 --dest-os=linux

And some adjustments on the common.gypi file (thanks to http://stackoverflow.com/a/36868753⁠ and https://gcc.gnu.org/onlinedocs/gcc-6.1.0/gcc/x86-Options.html#x86-Options⁠). I added the line:

{
   'variables': {
	 ...
     'v8_target_arch': 'x87',
     ...

And replace:

'conditions': [
      [ 'target_arch=="ia32"', {
        'cflags': [ '-m32' ],
        'ldflags': [ '-m32' ],

By:

'conditions': [
      [ 'target_arch=="ia32"', {
        'cflags': [ '-m32', '-march=athlon', '-mfpmath=387' ],
        'ldflags': [ '-m32', '-march=athlon', '-mfpmath=387' ],

I lost some time to understand and get valid binaries, so for those that be interested or for other non standard platform, you could modified this file⁠ for your configuration.

⁠Getting this image

docker pull insecurity/node-32bit-x87:latest

⁠Rebuild this image

git clone [email protected]:jtof_fap/node-32bit-x87.git
cd node-32bit-x87
[modify x87/common.gypi or Dockerfile for your non standard architecture]
docker build -t "node:latest" .
[share...]

⁠How to use this image

This image is a base for node:onbuild image. You could use it to run a single Node.js script:

docker run -it --rm --name NodeJS -v "$PWD":/srv/app -w /srv/app insecurity/node-32bit-x87:latest node your-daemon-or-script.js

For the rest, see the node-32bit-x87-onbuild⁠ image:
