Installing tools

Installing Clojure and Lein

While the final image will be built in a multi-stage docker container, development is much easier with local tools.

Installing Clojure

See the Clojure Getting Started Guide.

Installing Lein

See Installing Leiningen. I recommend you install it via your preferred Package Manager if possible.

Installing Docker

See the Docker Install Guide

Installing gcloud and kubectl

The Kubernetes Engine Quickstart shows how to quickly install the tools you need, and run a minimal generic app to verify your setup. Be sure to follow the instructions for Local Shell.

Set default project

$ gcloud config set project [PROJECT_ID]

Set default compute zone

$ gcloud config set compute/zone [COMPUTE_ZONE]

I use us-west1-a
