consul-template-cookbook

Installs and configures consul-template.

This is a fork of https://github.com/adamkrone/chef-consul-template with the following changes:

• Drop support for Windows
• No longer use libarchive as it causes a lot of problems.
• Use the tgz packages instead of the zip ones.
• Use a more modern style of defining resources.
• Use poise_service to define the service.
• Collapse all the recipes into default.
• Only define the checksums for the 0.20.0, 0.19.5, and 0.18.0. Or in other words, just for the latest 3 minor versions.
• Support the arm architecture.
• Only support the linux OS.

LWRP

consul_template_config

Creates configuration files in node['consul_template']['config_dir'], and
reloads the configuration.

For example, if you want to generate HAProxy's config using consul-template,
you may include something like this in your recipe:

consul_template_config 'haproxy' do
  templates [{
    source: '/etc/haproxy/haproxy.cfg.ctmpl',
    destination: '/etc/haproxy/haproxy.cfg',
    command: 'service haproxy restart'
  }]
  notifies :reload, 'service[consul-template]', :delayed
end
