Development Guide

This document is intended to be the canonical source of truth for things like supported toolchain versions for building Vault operator. If you find a requirement that this doc does not capture, please submit an issue on github.

This document is intended to be relative to the branch in which it is found. It is guaranteed that requirements will change over time for the development branch, but release branches of Vault operator should not change.

Build Vault operator

Some of the Vault operator development helper scripts rely on a fairly up-to-date GNU tools environment, so most recent Linux distros should work just fine out-of-the-box.

Setup GO

Vault operator is written in Google’s GO programming language. Currently, Vault operator is developed and tested on go 1.9.2. If you haven’t set up a GO development environment, please follow these instructions to install GO.

Testing Vault operator

Unit tests

$ ./hack/make.py test unit

Run e2e tests

Vault operator uses Ginkgo to run e2e tests.
