Usage Examples

Including in a Cookbook Recipe

You can simply include it in a recipe:

include_recipe 'kong'

Don't forget to include the kong cookbook as a dependency in the metadata.

# metadata.rb
# [...]

depends 'kong', '~> 0.1.0'

Including in the Run List

Another alternative is to include the default recipe in your Run List:

{
  "name": "api.example.com",
  "[...]": "[...]",
  "run_list": [
    "recipe[kong]"
  ]
}

Configuring the Cassandra Server Address

It is highly recommended to use an external Cassandra server with this cookbook.

For example:

node.default['kong']['kong.yml']['databases_available']['cassandra']\
  ['properties']['hosts'] = 'cassandra.example.com'

include_recipe 'kong'

If you want to use the local Cassandra server installed by this cookbook, it is recommended to set the following attributes:

node.default['cassandra']['cluster_name'] = # ...
node.default['cassandra']['install_method'] = # ...
# node.default['cassandra'][...]
# ...

include_recipe 'kong'

See the cassandra-dse cookbook documentation.

By default, this cookbook installs a local Cassandra server if the 'hosts' attribute is not set or is set to 'localhost'. You can use the node['kong']['manage_cassandra'] attribute to force this behavior.

The HTTPS Certificate

This cookbook uses the ssl_certificate cookbook to create the HTTPS certificate. The namespace used is node['kong']. For example:

node.default['kong']['common_name'] = 'api.example.com'
include_recipe 'kong'

See the ssl_certificate namespace documentation for more information.

You can disable the SSL certificate creation by setting the node['kong']['kong.yml']['ssl_cert_path'] and node['kong']['kong.yml']['ssl_key_path'] attributes. You can use the node['kong']['manage_ssl_certificate'] attribute to force this behavior.
