Docker - Error: EEXIST: file already exists, symlink

Question

I have developed a small "proof of concept" ApostropheCMS application. The application runs fine with node app.js . I'm trying to build and deploy with Docker for Windows on Windows 7 with Oracle VM VirtualBox following this tutorial .

I am able to deploy the mongo image . I am able to build my application image using the default Dockerfile. When I attempt to run my application, docker image linked with the mongo image I receive the following error:

$ docker run --link=ato-home-db:mongodb -p 3000:3000 ato-home-webapp

ato-home-webapp@2.0.0 start /app node app.js fs.js:1014 return binding.symlink(preprocessSymlinkDestination(target, type, path), ^ Error: EEXIST: file already exists, symlink '/app/node_modules/apostrophe/lib/modules/apostrophe-assets/public' -> '/app/public/modules/apostrophe-assets' at Object.fs.symlinkSync (fs.js:1014:18) at Object.self.linkAssetFolderOnUnix (/app/node_modules/apostrophe/lib/modules/apostrophe-assets/index.js:646:10) at Object.self.linkAssetFolder (/app/node_modules/apostrophe/lib/modules/apostrophe-assets/index.js:612:14) at /app/node_modules/apostrophe/lib/modules/apostrophe-assets/index.js:578:14 at /app/node_modules/@sailshq/lodash/lib/index.js:3253:15 at baseForOwn (/app/node_modules/@sailshq/lodash/lib/index.js:2223:14) at /app/node_modules/@sailshq/lodash/lib/index.js:3223:18 at Function.

I'm hoping for a possible solution or suggestions for ApostropheCMS tutorials or "How Tos" to get past this roadblock.

I am new to ApostropheCMS and Docker. Any input would be greatly appreciated. I can supply additional information if helpful.

I'm going to assume that you're building your image on Windows (to a Linux container). Please try rebuilding your image in a Unix environment.
