Anyone who deploys their Rails 3.x or 4.x utilizing the asset pipeline and doesn?t precompile those assets yet deploys to Heroku, knows it can take a really long time for your deployment.
I searched around a bit and found a great article on how to shave some time off my Heroku deployments. ?Alex MacCaw has a nice write up about the process:
If you?re using Heroku, the first step is enabling a Memcache addon. I?ve gone with the?
memcachier?service, as they?ve got a generous free plan (which is all we need at this stage).
heroku addons:add memcachier:dev
Then we need to make sure the environmental variables are available to your app during the pre-compilation stage. Usually this isn?t the case on Heroku, but they?ve got a new labs feature called?
user-env-compile?which will do the trick.
heroku labs:enable user-env-compile
Next you?ll need to add the?
memcachier?gems to your Gemfile. Finally, the last step is to configure Sprockets.
Since I am using Rails:
With Rails, just configure the assets cache store in
And the time savings would be?.
?An example of time saving with a relatively small project:
Not using the speed-up method, deploy time:?2 minutes 40 seconds
Using the above method:?47 seconds
It is definitely worth the little effort.
