A Capistrano Rails Guide

why cap?

Capistrano automates pushing out a new version of your application to a deployment location.

I've been writing and deploying Rails apps for a while, but I avoided using Capistrano until recently. I've got a pretty simple one-host deployment, and even though everyone said Capistrano was great, every time I tried to get started I just got snowed under not being able to figure out exactly what I wanted to do, and figured I wasn't having that much trouble doing it "manually".

-# delete all evicted pods from all namespaces
-kubectl get pods --all-namespaces | grep Evicted | awk '{print $2 " --namespace=" $1}' | xargs kubectl delete pod
-# delete all containers in ImagePullBackOff state from all namespaces
-kubectl get pods --all-namespaces | grep 'ImagePullBackOff' | awk '{print $2 " --namespace=" $1}' | xargs kubectl delete pod
-# delete all containers in ImagePullBackOff or ErrImagePull or Evicted state from all namespaces

	## Database
	The location of the database Heroku provides can be found in the environment
	variable DATABASE_URL. Check the configure-block of toodeloo.rb for an example
	on how to use this.

	## Server
	Heroku is serving your apps with thin, with means you have all your thin goodness available,
	such as EventMachine.
