Invalid ELF header error thrown

[keerthivasan-r]

I have built docker images for i05 iteration using Docker quick terminal in windows 8.1. It built successfully. when i try to run using Kitematic, i get the following error.

Can anyone help on this?

Did i04 and i03 etc work for you?

I had a similar issue. The problem is caused when you build the docker images having first run an npm build on your host machine (your windows box in your case). That creates a node_modules directory which contains binary some binary dependencies which aren't portable between your host machine and the Linux Docker image. That's what's causing the ELF header warnings. It's saying that it doesn't understand the library header for for what it expected to be a linux shared object library.

Easy way to fix it is just to remove the node_modules directories before you build the docker containers.
A better fix would be if we did an addition of node_modules into the .dockerignore file and did a wee pull request. Though since I'm far from an expert in Node, I'd love to get someone else's opinion on this as a fix.

Ok , i will try that and let you know.

I removed npm_modules and did npm install in the Docker terminal (Linux VM). I built the image again. when i run it, again the same error is thrown.

@matt-oc I did try to do the same thing with i04. it just works fine. Thanks guys! Let me know if you get any findings.

npm rebuild fixes these errors for me.
