Setting up Chef Client

We've set up a chef server in the previous post. That was on the host. Remember , we're planning to host the client on a Vagrant virtualbox and the server on the development box

We need an /etc/chef directory to store the configurations for the client. We put client.rb and validation.pem in there :

on the node , ie on the Vagrant box sudo mkdir -p /etc/chef

To create the client.rb and validation.pem , you can do one of the two steps :

1. With Workstation

  #On Workstation
  ~> knife configure client ./

Now scp the client.rb and validation.pem files generated at the current working directory of the node.

2. Without Workstation

Create a barebone /etc/chef/client.rb directly on the client :

#/etc/chef/client.rb on Node
log_level        :info
log_location     STDOUT
chef_server_url  ''
validation_client_name 'chef-validator'

At a minimum client.rb must contain the configuration settings necessary for chef-client to communicate with the chef-server.

Also, download the validation.pem file from chef-server to /etc/chef/ on the node

On the node , run : sudo chef-client -i 3600 This will register the node with the server , and create client.pem key in /etc/chef/ directory in the node. And starts the chef-client which will poll the chef-server every 3600 seconds for changes.

On the server, run : knife node list This should list your newly added client. If it does , congratulations! Your chef client is up and running .

Here's another document that's helpful in getting chef server and client set up.
