Quick / Cached Bundles on ElasticBeanstalk

Bonus, support Rack 1.4.5 with puma for Rails 3 apps

Basically we bundle install on one box, upload the result to a dedicated s3 bucked and then other servers/nodes can download the gems and save a ton of time compiling them.

I can not stress enough how the bucked should be dedicated as it will often remove all the files in the bucket to clear the cache / do a new gem build each month incase changes are made to backing ami / software, you can adjust the prefix to clear the bundle "cache key" more frequently by appending more date modifiers such as day or hour if you run into issues.

Note: You can remove 14downgradepuma if your app runs on Rails 4

#1 Generate Public & Private Keypair
 
#2 Create receipt.json - eg below - careful with line-endings, etc if line breaks
 
#3 Create signature & Encode
openssl dgst -binary -sha1 -sign private.pem receipt.json | openssl base64 > signature.txt
 
#4 Verify using OpenSSL & public key
openssl base64 -d -in signature.txt -out signature.sha1 | openssl dgst -sha1 -verify public.pem -signature signature.sha1 receipt.json
