Development Guide

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

Build Searchlight

Some of the Searchlight 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

Searchlight is written in Google’s GO programming language. Currently, Searchlight 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.

Download Source

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

Install Dev tools

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

$ ./hack/builddeps.sh

Build Binary

$ ./hack/make.py
$ searchlight version

Run Binary Locally

$ searchlight run \
  --secure-port=8443 \
  --kubeconfig="$HOME/.kube/config" \
  --authorization-kubeconfig="$HOME/.kube/config" \
  --authentication-kubeconfig="$HOME/.kube/config" \
  --authentication-skip-lookup

Dependency management

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

$ glide slow

Build Operator Docker image

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

# Build Docker image
$ ./hack/docker/searchlight/setup.sh; ./hack/docker/searchlight/setup.sh push

# Add docker tag for your repository
$ docker tag appscode/searchlight:<tag> <image>:<tag>

# Push Image
$ docker push <image>:<tag>

# Example:
docker tag appscode/searchlight:default aerokite/searchlight:default
docker push aerokite/searchlight:default

Build Icinga Docker image

Default Icinga also includes hyperalert plugin.

gsutil cp gs://appscode-dev/binaries/hyperalert/<tag>/hyperalert-linux-amd64 plugins/hyperalert

We can add hyperalert plugin in Icinga downloaded from anywhere. We just need to add plugin in plugins directory and name it as hyperalert.

# Build Docker image
./hack/docker/icinga/build.sh

# This will push docker image to any repositories

# Add docker tag to image for your repository
docker tag appscode/icinga:<tag>-k8s <repository>:<tag>-k8s

# Push Image
docker push <repository>:<tag>-k8s

# Example:
docker tag appscode/icinga:default-k8s aerokite/icinga:default-k8s
docker push aerokite/icinga:default-k8s
