Building Grafana from source on Fedora

Here are the official docs for building Grafana from source.  And below are my notes on how to build Grafana, starting from a clean Fedora 27 Cloud image.

# Install Dependencies
curl https://dl.yarnpkg.com/rpm/yarn.repo > /etc/yum.repos.d/yarn.repo
sudo yum install golang yarn rubygems ruby-devel redhat-rpm-config rpm-build git -y
gem install fpm
sudo yarn install --pure-lockfile
npm install -g yarn & yarn install

Setup the go environment.

# go environment
mkdir ~/go
export GOPATH=~/go
export PATH=$PATH:$(go env GOPATH)/bin

Download the various repositories required to build.  Here you could also clone your fork/branch of Grafana into $GOPATH/src.

# Pull sources required to build
go get github.com/grafana/grafana golang.org/x/sync/errgroup github.com/codegangsta/cli 
cd $GOPATH/src/github.com/grafana/grafana
npm install

Now you can make any sort of local changes, or just build from HEAD.

# go run build.go setup # takes 45 seconds
$ time go run build.go build pkg-rpm # takes about 7 minutes

The build will spit out an RPM in a folder called dist:

Created package {:path=>"./dist/grafana-5.0.0-1517715437pre1.x86_64.rpm"}
