Add your API using the declarative config

Create a config.json or config.yml file and describe your api.

---
  apis:
    -
      name: "mockbin"
      attributes:
        upstream_url: "http://mockbin.com/"
        request_host: "mockbin.com"

{
    "apis": [
        {
            "name": "mockbin",
            "attributes": {
                "upstream_url": "http://mockbin.com/",
                "request_host": "mockbin.com"
            }
        }
    ]
}

Apply this configuration using:

kongfig apply --path ./config.json --host localhost:8001

You should see a similar command output when applying the config:

...

POST 201 http://localhost:8001/apis
 { upstream_url: 'http://mockbin.com/',
   request_host: 'mockbin.com',
   name: 'mockbin' }
Response status Created:
 { upstream_url: 'http://mockbin.com/',
   id: '94219b08-e70e-44a4-c4cd-bf3c9bc31ca1',
   name: 'mockbin',
   created_at: 1445247516000,
   request_host: 'mockbin.com' }

Forward your requests through Kong

curl -i -X GET \
  --url http://localhost:8000/ \
  --header 'Host: mockbin.com'

Enabling Plugins

Prerequisite: Ensure any plugin you want to use has been enabled within Kong's configuration - Enabling Plugins

Configure the plugin for your API

Update the config.json file that describes your api.

{
    "apis": [
        {
            "name": "mockbin",
            "attributes": {
                "upstream_url": "http://mockbin.com/",
                "request_host": "mockbin.com"
            },
            "plugins": [
                {
                    "name": "key-auth"
                }
            ]
        }
    ]
}

Apply this configuration using:

kongfig apply --path ./config.json --host localhost:8001

You should see the following within the command output when applying the config:

...

POST 201 http://localhost:8001/apis/mockbin/plugins
 { name: 'key-auth' }
Response status Created:
 { api_id: '94219b08-e70e-44a4-c4cd-bf3c9bc31ca1',
   id: '2e34fd09-dce2-4f5d-cf55-99bc68e19843',
   created_at: 1445248597000,
   enabled: true,
   name: 'key-auth',
   config: { key_names: [ 'apikey' ], hide_credentials: false } }

Verify that the plugin is enabled for your API

Issue the following cURL request to verify that the key-auth plugin was enabled for your API:

curl -i -X GET \
  --url http://localhost:8000/ \
  --header 'Host: mockbin.com'

The response should be 403 Forbidden.

Adding Consumers

We currently have support for managing a limited set of consumers i.e. internal applications and services.

If you have a finite set of your own applications that need access to your API's (i.e. a mobile app, micro-services deployed by Puppet), then the following approach will work well for you.

Currently limited to the first page of consumers (that is 100) returned by the Kong API

Create a Consumer

Declare your consumer in your config.json file

{
    "apis": [
        "..."
    ],

    "consumers": [
        {
            "username": "iphone-app"
        }
    ]
}

kongfig apply --path ./config.json --host localhost:8001

You should see the following within the command output when applying the config:

POST 201 http://localhost:8001/consumers
 { username: 'iphone-app' }
Response status Created:
 { username: 'iphone-app',
   created_at: 1445251342000,
   id: '3f18c498-10fe-4937-c910-3b6cb7cc7b49' }

Adding credentials

Declare your consumer credentials in your config.json file

{
    "consumers": [
        {
            "username": "iphone-app",
            "credentials": [
                {
                    "name": "key-auth",
                    "attributes": {
                        "key": "very-secret-key"
                    }
                }
            ]
        }
    ]
}

You should see the following within the command output when applying the config:

...

POST 201 http://localhost:8001/consumers/iphone-app/key-auth
 { key: 'very-secret-key' }
Response status Created:
 { created_at: 1445251445000,
   consumer_id: '3f18c498-10fe-4937-c910-3b6cb7cc7b49',
   key: 'very-secret-key',
   id: 'feb787a9-fc44-47b3-c743-7575ef6a65a5' }

Verify that your Consumer credentials are valid

curl -i -X GET \
  --url http://localhost:8000 \
  --header "Host: mockbin.com" \
  --header "apikey: very-secret-key"

Specifying the Kong Host

You can alternatively specify the desired host in the configuration file itself, like so:

{
    "host": "localhost:8001",
    "apis": [
        "..."
    ]
}

Removing Declarations

You are able to ensure that previous declarations have been removed, like so:

{
    "apis": [
        {
            "name": "mockbin",
            "ensure": "removed"
        }
    ]
}

Using Custom Headers

You can specify any number of custom headers to be included with every request made by Kongfig.

These can be used via the command line, like so:

kongfig apply --host localhost:8001 --path config.yaml --header apikey:secret --header name:value

or via the config file, like so:

---
  headers:
    - 'apikey:secret'
    - 'name:value'

  apis:
    -
      name: "mockbin"
      attributes:
        upstream_url: "http://mockbin.com/"
        request_host: "mockbin.com"
