Tutum Zero Downtime Re-deploy

I tweeted Tutum last night asking if they're looking at implementing zero downtime re-deploys for a given service. Slightly surprised by their response as it seems like a critical feature if you want to use the service for a production environment.

"not a top priority, but by Spring :)"

As Tutum currently doesn't support graceful termination of containers within a service, I was experiencing a 5-10 second window of 503 errors, so decided to use the following hack (code below) until the feature is officially implemented.

##If you want to install OpenJDK
#sudo apt-get update
#sudo apt-get install openjdk-8-jre-headless -y

###Or if you want to install Oracle JDK, which seems to have slightly better performance
sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update
sudo apt-get install oracle-java8-installer

Motivation

• expression-oriented programming one of the great advances of FP
• expressions plug together like legos, making more malleable programming experience in-the-small

Examples

Write in an expression-oriented style, scoping variables as locally as possible:

Lots of stack traces and error messages for CKAN, followed by a comment about how I fixed it (that time).
NB don't email me privately for help - ask on StackOverflow #ckan instead.
