Chef for topstack

TopStack makes heavy use of Chef during operation. You'll need any standard Chef server, with some additional cookbooks provided in the TopStackChefRepo project.

Here are some sample steps to set up Chef for TopStack.

1. Obtain a chef package.

2. Run normal installation.

3. Unzip the cookbooks from the TopStack Chef repository.

   Perform the following steps on your deployment instance. (If you're not installing Chef on your deployment instance, you'll need to obtain credentials such as the "webui.pem" described below and transfer them to the instance.)

   mkdir -p /etc/ChefRepo/cookbooks
   mkdir -p /etc/ChefRepo/roles
   cd /etc/ChefRepo && tar -zxvf ${TOPSTACK_DIR}/TopStackChefRepo/dist/topstack-chef.tar.gz
   cat <<-EOC > /etc/chef/knife.rb
   log_level            :info
   log_location         STDOUT
   node_name           'chef-webui'
   cache_type          'BasicFile'
   cache_options( :path => "/root/.chef/checksums" )
   client_key             "/etc/chef/webui.pem"
   
   cookbook_path      [ "/etc/ChefRepo/cookbooks" ]
   cookbook_copyright "transcendcomputing com"
   cookbook_email     "[email protected]"
   cookbook_license   "apachev2"
   
   chef_server_url    "http://localhost:4000"
   
   validation_key      "/etc/chef/validation.pem"
   validation_client_name "chef-validator"
   EOC

   knife role from file /etc/ChefRepo/roles/transcend_memcached_1_4_5.rb -c /etc/chef/knife.rb
   
   # Ensure the TopStack instanc is a chef admin
   EDITOR="sed -i 's/\\"admin\": false/\\"admin\\": true/g'" knife client edit ${HOSTNAME} -c /etc/chef/knife.rb
   # Upload cookbooks
   knife cookbook upload /etc/ChefRepo/cookbooks/* -a -c /etc/chef/knife.rb
   
   knife environment from file /etc/ChefRepo/environments/transcend_production.json -c /etc/chef/knife.rb

4. Configure your TopStack deployment instance, as described in Deployment Instance Setup.
