Development Guide

This document is intended to be the canonical source of truth for things like supported toolchain versions for building Guard. 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 Guard should not change.

Build Guard

Some of the Guard 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

Guard is written in Google’s GO programming language. Currently, Guard is developed and tested on go 1.8.3. If you haven’t set up a GO development environment, please follow these instructions to install GO.

Download Source

$ go get github.com/appscode/guard
$ cd $(go env GOPATH)/src/github.com/appscode/guard

Install Dev tools

To install various dev tools for Guard, run the following command:

# setting up dependencies for compiling guard...
$ ./hack/builddeps.sh

Build Binary

$ ./hack/make.py
$ guard version

Dependency management

Guard uses Glide to manage dependencies. Dependencies are already checked in the vendor folder. If you want to update/add dependencies, run:

$ glide slow

Build Docker images

To build and push your custom Docker image, follow the steps below. To release a new version of Guard, please follow the release guide.
