Usage

consul::default

This uses the binary installation recipe by default. It also starts consul at boot time.

consul::install_binary

Include consul::install_binary in your node's run_list:

{
  "run_list": [
    "recipe[consul::install_binary]"
  ]
}

consul::install_source

Include consul::install_source in your node's run_list:

{
  "run_list": [
    "recipe[consul::install_source]"
  ]
}

consul::ui

This installs the UI into a specified directory.

Include consul::ui in your node's run_list:

{
  "run_list": [
    "recipe[consul::ui]"
  ]
}

LWRP

Adding service without check
consul_service_def 'voice1' do
  port 5060
  tags ['_sip._udp']
  notifies :reload, 'service[consul]'
end
Adding service with check
consul_service_def 'voice1' do
  port 5060
  tags ['_sip._udp']
  check(
    interval: '10s',
    script: 'echo ok'
  )
  notifies :reload, 'service[consul]'
end
Removing service
consul_service_def 'voice1' do
  action :delete
  notifies :reload, 'service[consul]'
end

Be sure to notify the Consul resource to restart when your service def changes.

Getting Started

To bootstrap a consul cluster follow the following steps:

  1. Bootstrap a few (preferablly 3 nodes) to be your consul servers, these will be the KV masters.
  2. Put node['consul']['servers'] =["Array of the bootstrapped servers ips or dns names"] in your environment.
  3. Apply the consul cookbook to these nodes with node['consul']['service_mode'] = 'cluster' (I put this in this in a CONSUL_MASTER role).
  4. Let these machines converge, once you can run consul members and get a list of all of the servers your ready to move on
  5. Apply the consul cookbook to the rest of your nodes with node['consul']['service_mode'] = 'client' (I put this in the environment)
  6. Start added services and checks to your cookbooks.
  7. If you want to get values out of consul to power your chef, curl localhost:8500/v1/kv/key/path?raw in your cookbook.
