GoKong

A kong go client fully tested with no mocks!!

IMPORTANT

GoKong has now been updated to support kong v1.0.0. This is a breaking change release is not compatible with any versions <1.0.0. The good news is the guys over at Kong have stated that they are not going to make any breaking changes now (following semver). If you need a version of gokong that supports Kong <1.0.0 then use the branch kong-pre-1.0.0.

GoKong

GoKong is a easy to use api client for kong. The difference with the gokong library is all of its tests are written against a real running kong running inside a docker container, yep that's right you won't see a horrible mock anywhere!!

Supported Kong Versions

As per travis build:

KONG_VERSION=1.0.0

Importing

To add gokong via go get:

go get github.com/kevholditch/gokong

Usage

Import gokong

import (
  "github.com/kevholditch/gokong"
)

To create a default config for use with the client:

config := gokong.NewDefaultConfig()

NewDefaultConfig creates a config with the host address set to the value of the env variable KONG_ADMIN_ADDR. If the env variable is not set then the address is defaulted to http://localhost:8001.

There are a number of options you can set via config either by explicitly setting them when creating a config instance or by simply using the NewDefaultConfig method and using env variables. Below is a table of the fields, the env variables that can be used to set them and their default values if you do not provide one via an env variable:

Config property	Env variable	Default if not set	Use
HostAddress	KONG_ADMIN_ADDR	http://localhost:8001	The url of the kong admin api
Username	KONG_ADMIN_USERNAME	not set	Username for the kong admin api
Password	KONG_ADMIN_PASSWORD	not set	Password for the kong admin api
InsecureSkipVerify	TLS_SKIP_VERIFY	false	Whether to skip tls certificate verification for the kong api when using https
ApiKey	KONG_API_KEY	not set	The api key you have used to lock down the kong admin api (via key-auth plugin)
AdminToken	KONG_ADMIN_TOKEN	not set	The api key you have used to lock down the kong admin api (Enterprise Edition )

You can of course create your own config with the address set to whatever you want:

config := gokong.Config{HostAddress:"http://localhost:1234"}

Also you can apply Username and Password for admin-api Basic Auth:

config := gokong.Config{HostAddress:"http://localhost:1234",Username:"adminuser",Password:"yoursecret"}

If you need to ignore TLS verification, you can set InsecureSkipVerify:

config := gokong.Config{InsecureSkipVerify: true}

This might be needed if your Kong installation is using a self-signed certificate, or if you are proxying to the Kong admin port.

Getting the status of the kong server:

kongClient := gokong.NewClient(gokong.NewDefaultConfig())
status, err := kongClient.Status().Get()

Gokong is fluent so we can combine the above two lines into one:

status, err := gokong.NewClient(gokong.NewDefaultConfig()).Status().Get()

Consumers

Create a new Consumer (for more information on the Consumer Fields see the Kong documentation):

consumerRequest := &gokong.ConsumerRequest{
  Username: "User1",
  CustomId: "SomeId",
}

consumer, err := gokong.NewClient(gokong.NewDefaultConfig()).Consumers().Create(consumerRequest)

Get a Consumer by id:

consumer, err := gokong.NewClient(gokong.NewDefaultConfig()).Consumers().GetById("e8ccbf13-a662-45be-9b6a-b549cc739c18")

Get a Consumer by username:

consumer, err := gokong.NewClient(gokong.NewDefaultConfig()).Consumers().GetByUsername("User1")

List all Consumers:

consumers, err := gokong.NewClient(gokong.NewDefaultConfig()).Consumers().List()

Delete a Consumer by id:

err := gokong.NewClient(gokong.NewDefaultConfig()).Consumers().DeleteById("7c8741b7-3cf5-4d90-8674-b34153efbcd6")

Delete a Consumer by username:

err := gokong.NewClient(gokong.NewDefaultConfig()).Consumers().DeleteByUsername("User1")

Update a Consumer by id:

consumerRequest := &gokong.ConsumerRequest{
  Username: "User1",
  CustomId: "SomeId",
}

updatedConsumer, err := gokong.NewClient(gokong.NewDefaultConfig()).Consumers().UpdateById("44a37c3d-a252-4968-ab55-58c41b0289c2", consumerRequest)

Update a Consumer by username:

consumerRequest := &gokong.ConsumerRequest{
  Username: "User2",
  CustomId: "SomeId",
}

updatedConsumer, err := gokong.NewClient(gokong.NewDefaultConfig()).Consumers().UpdateByUsername("User2", consumerRequest)

Plugins

Create a new Plugin to be applied to all Services, Routes and Consumers do not set ServiceId, RouteId or ConsumerId. Not all plugins can be configured in this way (for more information on the Plugin Fields see the Kong documentation):

pluginRequest := &gokong.PluginRequest{
  Name: "request-size-limiting",
  Config: map[string]interface{}{
    "allowed_payload_size": 128,
  },
}

createdPlugin, err := gokong.NewClient(gokong.NewDefaultConfig()).Plugins().Create(pluginRequest)

    "limits.sms.minute": 20,
  },
}

createdPlugin, err := client.Plugins().Create(pluginRequest)

Create a new Plugin for a single Service (only set ServiceId), Not all plugins can be configured in this way (for more information on the Plugin Fields see the Kong documentation):

client := gokong.NewClient(gokong.NewDefaultConfig())

serviceRequest := &gokong.ServiceRequest{
  Name:     String("service"),
  Protocol: String("http"),
  Host:     String("example.com"),
}

createdService, err := client.Services().Create(serviceRequest)

pluginRequest := &gokong.PluginRequest{
  Name: "response-ratelimiting",
  ServiceId: gokong.ToId(*createdService.Id),
  Config: map[string]interface{}{
    "limits.sms.minute": 20,
  },
}

createdPlugin, err := client.Plugins().Create(pluginRequest)

Create a new Plugin for a single Route (only set RouteId), Not all plugins can be configured in this way (for more information on the Plugin Fields see the Kong documentation):

  Hosts:        StringSlice([]string{"example.com"}),
  Paths:        StringSlice([]string{"/"}),
  StripPath:    Bool(true),
  PreserveHost: Bool(false),
  Service:      &gokong.RouteServiceObject{Id: *createdService.Id},
}

createdRoute, err := client.Routes().Create(routeRequest)

pluginRequest := &gokong.PluginRequest{
  Name: "response-ratelimiting",
  RouteId: gokong.ToId(*createdRoute.Id),
  Config: map[string]interface{}{
    "limits.sms.minute": 20,
  },
}

createdPlugin, err := client.Plugins().Create(pluginRequest)

Get a plugin by id:

plugin, err := gokong.NewClient(gokong.NewDefaultConfig()).Plugins().GetById("04bda233-d035-4b8a-8cf2-a53f3dd990f3")

Configure a plugin for a Consumer

To configure a plugin for a consumer you can use the CreatePluginConfig, GetPluginConfig and DeletePluginConfig methods on the Consumers endpoint. Some plugins require configuration for a consumer for example the [jwt plugin[(https://getkong.org/plugins/jwt/#create-a-jwt-credential).

Create a plugin config for a consumer:

createdPluginConfig, err := gokong.NewClient(gokong.NewDefaultConfig()).Consumers().CreatePluginConfig("f6539872-d8c5-4d6c-a2f2-923760329e4e", "jwt", "{\"key\": \"a36c3049b36249a3c9f8891cb127243c\"}")

Get a plugin config for a consumer by plugin config id:

pluginConfig, err := gokong.NewClient(gokong.NewDefaultConfig()).Consumers().GetPluginConfig("58c5229-dc92-4632-91c1-f34d9b84db0b", "jwt", "22700b52-ba59-428e-b03b-ba429b1e775e")

Delete a plugin config for a consumer by plugin config id:

err := gokong.NewClient(gokong.NewDefaultConfig()).Consumers().DeletePluginConfig("3958a860-ceac-4a6c-9bbb-ff8d69a585d2", "jwt", "bde04c3a-46bb-45c9-9006-e8af20d04342")

Contributing

I would love to get contributions to the project so please feel free to submit a PR. To setup your dev station you need go and docker installed.

Once you have cloned the repository the make command will build the code and run all of the tests. If they all pass then you are good to go!

If when you run the make command you get the following error:

gofmt needs running on the following files:

Then all you need to do is run make goimports this will reformat all of the code (I know awesome)!!
