Reduce Heroku Compiled Slug Size


I've just updated rails to v2.3.6 on my app under a bamboo-ree-1.8.7 stack and the compiled slug size has grown up to 40.5Mb! Previous to that last git push, the slug size was about 20Mb and was using rails v2.3.5.

Is it because my slug has both of rails versions installed? Probably I'm missing something but I haven't added any special code/files into my app as to increase the slug size by ~20Mb.

Can you point me on how can I reduce the slug size?

Any help will be greatly appreciated.

Thank you very much in advance.


Solution

  • One thing that helps is adding a .slugignore file to the root of your project to tell Heroku not to compile certain files or directories into the slug. Mine looks like this:

    *.psd
    *.pdf
    test
    spec
    features
    doc
    public
    

    The public entry is in there because I serve all static files from Amazon's S3 service; just leave that line off if you're not using an external content-delivery system.
