Re: Bazel as Clojure build tool

[Nathan Fisher]

It's not something that as a user you'd be exposed to. The easiest way to 
demonstrate the impact is to write a library and test target in two 
different ways for a Java project.

1. using java_library target for the library.
2. using genrule for the library that calls out to javac.

Run the test target, introduce whitespace into the library, and run the 
test target again. It should only do a full execution in the 2nd example.

Clojure on Kubernetes quickstart, patterns, libraries, ideas...

[Jason Whitlark]

A while back I wrote a quickstart for a minimal Clojure setup running on 
Kubernetes .  It's time 
to revisit and update it.

I wanted to both ask for feedback for things to add/remove, and more 
generally ask what projects, patterns, libraries, snippets, etc. have you 
have found useful when using Clojure on K8s.  In my experiments, I've 
noticed the way I used Clojure in this environment is changing, with focus 
narrowing, tools changing, more emphasis on env vars, difficulties and 
differences in building on top of JDK 10, etc.  I'm writing up some of my 
thoughts, and wanted to start some discussion on the topic.

Cheers,
~Jason
