Heroku Slugsize shot up drastically

Hi,

Locally my application is 7MB without tests and logs, etc. The .git folder is 29 MB. I also have no gems / plugins in vendor folder. 95% of images sit on S3. However on committing to Heroku it shows -----> Compiled slug size is 62.7MB

What is wrong? It happened?

To add more context my .gitignore file is .bundle, db/.sqlite3, config/ database.yml, log/.log, tmp/, .idea, .redcar, .sass-cache/, multi_xml/, test/, doc/

Please advice

Make sure that you include a .slugignore file (similar to .gitignore, but for heroku) and that you do not include development and test gems (this is automatic on cedar, on the other stacks you need to add this manually).

Thank you Martin,

My GemFile puts all dev gems within Dev section group :development do   gem 'silent-postgres'   gem 'hirb'   gem 'wirble'   gem 'crack'   gem 'ap' end

About Slugignore, I gitignored all items which are to be slugignored. Does it not solve the problem?

Plus there are no plugins/gems in my vendor folder, the total size of my app in local directory without .git is 7MB.

You need to make sure that bundle (on heroku) does not include the development and test gems.

run “heroku config” and look for a BUNDLE_WITHOUT line that should contain development:test

If not then execute the following command:

heroku config:add BUNDLE_WITHOUT="development:test"

slugignore is useful to exclude assets like psd’s that live in your git but should not be part of slug. Also some of the less common gems count to your slug size even if they are not in your vendor directory. If you include gems through :git => they also automatically add to your slug size.

To give you a ballpark figure: My sites have a slugsize of about 50 to 60 meg on cedar on average.

If you run on cedar make sure you do not include therubyracer gem but instead use the built in node.js (see here for details: http://devcenter.heroku.com/articles/rails31_heroku_cedar)

Thanks a lot Martin. Only Aspen stack has preinstalled gems. (http:// installed-gems.heroku.com/) Bamboo and Cedar dont. Hence my slug is high. I need to reduce my gems.
