Stuff to build rpms for prometheus, node_exporter and alertmanager for amd64 until rpms are provided by the prometheus.io project itself.
Requires rpmbuild to be installed. To run, simply go into a subdir and run make.
Use make to build for RHEL6 or RHEL7 (depends on what system you run your build).
Use make clean to clean sources. This can help, when make fails (because of multiple downloaded versions of tar.gz file).
Use make deploy-bintray to build rpm and upload to bintray. Please set CREDENTIALS to <user_name>:<API_KEY>, REPOSITORY to <user_name>/<repo_name>.
