Tutorial: Add a demo plugin to your API

API settings

To add a Lua plugin to your API, you must specify the bundle name using the custom_middleware_bundle field:

{
    "name": "Tyk Test API",
    "api_id": "1",
    "org_id": "default",
    "definition": {
        "location": "header",
        "key": "version"
    },
    "auth": {
        "auth_header_name": "authorization"
    },
    "use_keyless": true,
    "version_data": {
        "not_versioned": true,
        "versions": {
            "Default": {
                "name": "Default",
                "expires": "3000-01-02 15:04",
                "use_extended_paths": true,
                "extended_paths": {
                    "ignored": [],
                    "white_list": [],
                    "black_list": []
                }
            }
        }
    },
    "proxy": {
        "listen_path": "/quickstart/",
        "target_url": "http://httpbin.org",
        "strip_listen_path": true
    },
    "custom_middleware_bundle": "test-bundle",
}

Global settings

To enable Lua plugins you need to add the following block to tyk.conf:

"coprocess_options": {
  "enable_coprocess": true,
},
"enable_bundle_downloader": true,
"bundle_base_url": "http://my-bundle-server.com/bundles/",
"public_key_path": "/path/to/my/pubkey",

enable_coprocess enables the rich plugins feature.

enable_bundle_downloader enables the bundle downloader.

bundle_base_url is a base URL that will be used to download the bundle, in this example we have “test-bundle” specified in the API settings, Tyk will fetch the following URL: “http://my-bundle-server.com/bundles/test-bundle”.

public_key_path sets a public key, this is used for verifying signed bundles, you may omit this if unsigned bundles are used.

Running the Tyk Lua build

To use Tyk with Lua support you will need to use an alternative binary, it is provided in the standard Tyk package but it has a different service name.

Firstly stop the standard Tyk version:

service tyk-gateway stop

and then start the Lua build:

service tyk-gateway-lua start
