grafana Cookbook

A stand-alone cookbook for Grafana

Requirements

• apt
• nginx
• git

Attributes

As with most cookbooks I write, this one is hopefully flexible enough to be wrapped by allowing you to override as much as possible

grafana::default

• node['grafana']['install_type'] - The type of install we are going to use either git or zipfile
• node['grafana']['git']['url'] - The url for the git repo to use for Grafana
• node['grafana']['git']['branch'] - The sha or branch name to use
• node['grafana']['file']['type'] - the type of archive file. zip only at this stage
• node['grafana']['file']['url'] - The zipfile URL for the latest Grafana build
• node['grafana']['file']['checksum'] - The sha256 of the Grafana zipfile
• node['grafana']['install_path'] - The root directory where Grafana will be installed
• node['grafana']['install_dir'] - The directory to checkout into. A current symlink will be created in this directory as well.
• node['grafana']['es_server'] - The ipaddress or hostname of your elasticsearch server
• node['grafana']['es_port'] - The port of your elasticsearch server's http interface
• node['grafana']['es_role'] - eventually for wiring up discovery of your elasticsearch server
• node['grafana']['es_scheme'] - Scheme helper if elasticsearch is outside of this cookbook http:// or https://
• node['grafana']['graphite_server'] - The ipaddress or hostname of your graphite server
• node['grafana']['graphite_port'] - The port of your graphite server's http interface
• node['grafana']['graphite_role'] - eventually for wiring up discovery of your graphite server
• node['grafana']['graphite_scheme'] - Scheme helper if graphite is outside of this cookbook http:// or https://
• node['grafana']['user'] - The user who will own the files from the git checkout. (default: the web server user)
• node['grafana']['config_template'] - The template to use for Grafana's config.js
• node['grafana']['config_cookbook'] - The cookbook that contains said config template
• node['grafana']['webserver'] - Which webserver to use: apache, nginx or ''
• node['grafana']['webserver_hostname'] - The primary vhost the web server will use for Grafana
• node['grafana']['webserver_aliases'] - Array of any secondary hostnames that are valid vhosts
• node['grafana']['webserver_listen'] - The ip address the web server will listen on
• node['grafana']['webserver_port'] - The port the webserver will listen on
• node['grafana']['webserver_scheme'] - Scheme helper if webserver is outside of this cookbook http:// or https://

kibana::nginx

• node['grafana']['nginx']['template'] - The template file to use for the nginx site configuration
• node['grafana']['nginx']['template_cookbook'] - The cookbook containing said template
• node['grafana']['nginx']['enable_default_site'] - Should we disable the nginx default site (default: true)

Usage

grafana::default

The default recipe will:

• install Grafana from master into /opt/grafana/master and create a symlink called current in the same directory to master
• install nginx and serve the grafana application

If you want to use the zipfile distribution of Grafana update node['grafana']['install_type'] attribute to zipfile. Set node['grafana']['zipfile_checksum'] to appropriate sha256 value of latest zipfile.

If you don't want this cookbook to handle the webserver config simply set node['grafana']['webserver'] to '' in a role/environment/node somewhere. Please note that in this case you have to set node['grafana']['user'].

Nginx recipe, by default, will configure the appropriate proxy to your ElasticSearch server such that you don't have to expose it to the world.

NOTE There is NO security enabled by default on any of the content being served. If you would like to modify the nginx parameters, you should:

• create your own cookbook i.e. my-grafana
• copy the template for the webserver you wish to use to your cookbook
• modify the template as you see fit (add auth, setup ssl)
• use the appropriate webserver template attributes to point to your cookbook and template
