Doc request - how to create data nodes vs master nodes

[spuder]

It would be nice if the documentation outlined how to create the 3 different types of nodes

• data
• master
• client

From my testing it looks like the following

master

node.data => false
node.master => true

data

# data nodes are default
 node.data => true
 node.master => true

client

node.data => false
node.master => false

Where a full config looks like this:

elasticsearch_configure 'foo-elasticsearch' do
  configuration ({
    'cluster.name' => node['foo-elasticsearch']['config']['cluster_name'],
    'node.name' => Chef::Config[:node_name],
    'node.data' => node['foo-elasticsearch']['config']['node_data'],
    'node.master' => node['foo-elasticsearch']['config']['node_master']
    })
  action :manage
end

Then you can easily create 3 different roles to set the values of node['foo-elasticsearch']['config']['node_data']

• elasticsearch-master
• elasticsearch-data
• elasticsearch-client

I'm happy to document this, but it really isn't something implemented or handled in this cookbook, it's just Elasticsearch's implementation and configuration settings. I am not sure it's worth explaining a setting that this cookbook doesn't actually handle or touch. They are just arbitrary values that get passed through and written to the config file like any other. They are really ES settings, not Chef ones, nor do they have any special attention or handling within Chef.

Good point. I'm ok if you close this.
