playground-community's Introduction

KrakenD Playground

The KrakenD Playground is a demonstration environment that puts together the necessary pieces to get you started with our API Gateway, using example use-cases.

As KrakenD is an API gateway, we have added surrounding services:

Internal and third-party services that feed the gateway
Authentication/authorization examples, including JWT token-based authentication with Auth0 integration, a JWT token revoker, API-Key-based authentication, and basic authentication.
Integrations with Grafana+Influx (metrics), ELK (log storing and visualization), Jaeger (tracing), and RabbitMQ (for async agents).

Services

The docker-compose.yml includes the following services:

The API Gateway!

On port 8080, you have an instance of KrakenD Enterprise Edition with several endpoints. Its configuration is available at config/krakend/krakend.json, including descriptive @comments for each endpoint.

Fake API backend (Upstream)

On port 8000, you have a simple fake API that provides raw data to the gateway. You can add or remove data by adding XML, JSON, or RSS files in the data folder.

It runs in http://localhost:8000

Metrics, logs & tracing

KrakenD can export telemetry to several services; this demonstration has a few examples. After starting the service and calling some endpoints, you will see the activity in Jaeger, Grafana, and Kibana.

Metrics	Logging	Tracing
Grafana shows the metrics stored by KrakenD on InfluxDB (credentials: admin/admin)	Kibana shows the logs registered by Logstash and persisted in Elasticsearch	Jaeger shows the traces of the activity between the client and your end services, including times of hops.
URL: http://localhost:4000	URL: http://localhost:5601	URL: http://localhost:16686

NOTE: To import a Kibana dashboard with some valuable metrics, run in the console the following command once all has started:

    $ make elastic

Web client

This consumer of the API gateway is a simple Express JS application that interacts with KrakenD to fetch the data. All code is under images/spa-auth-web/.

The client is a Single Page Application using Auth0 to generate JWT tokens.

You don't need to install any npm locally; the docker image will download and install the dependencies in the container.

Visit http://localhost:3000

The async agent

A RabbitMQ instance is ready to accept AMQP messages to be delivered to the gateway.

You can insert messages in the krakend queue at http://localhost:15672/#/queues/%2F/krakend (credentials: guest/guest) and see how the async agent picks them and delivers them.

The JWT revoker

A simple implementation of a JWT revoker using the KrakenD remote bloomfilter client.

More information about JWT revoking is available at https://www.krakend.io/docs/authorization/revoking-tokens/

It runs on http://localhost:9000

Start the service

Only if you want to try the Auth0 integration...

Create a new SPA application in Auth0 and fill the autogenerated values they give you under images/spa-auth-web/auth0-variables.js

var AUTH0_CLIENT_ID='AUTH0_CLIENT_ID';
var AUTH0_DOMAIN='AUTH0_DOMAIN';
var AUTH0_AUDIENCE = 'AUTH0_AUDIENCE';

You must do this before starting the docker-compose. If you have started docker-compose before setting these variables, you must build the image again with docker compose build web.

Running the playground

To start the stack included in docker-compose

    $ make start

To follow the KrakenD logs after the complete stack is up & running

    $ make logs

To shut down the complete stack, removing all the volumes

    $ make stop

Play!

Fire up your browser, curl, postman, httpie, or anything else you like to interact with any published services.

Fake API: http://localhost:8000
KrakenD API Gateway: http://localhost:8080
Jaeger (tracing): http://localhost:16686
Kibana (logs): http://localhost:5601
Grafana (metrics): http://localhost:4000
Sample SPA for auth: http://localhost:3000
JWT revoker: http://localhost:9000

When you change the krakend.json, the changes are applied automatically.

💡 Bonus track - Flexible configuration

💡 Bonus track - Flexible configuration
We've added an example of flexible configuration, so you can view how it works in practice. Apart from the default config file, `krakend.json`, you will find a `krakend-flexible-config.tmpl` that includes some code snippets, invokes a template using variables, and show some basic logic (iterations & conditions). When working with the flexible configuration, you can optionally ask KrakenD to save the "compiled" output to a file. We've added a command `make compile-flexible-config` so you can see quickly and easily how KrakenD builds the final configuration file based on the existing templates. Internally KrakenD's flexible configuration uses Golang templating syntax.

Editing the API Gateway endpoints

To add or remove endpoints, edit the file krakend/krakend.json. The easiest way to do it is by dragging this file to the KrakenD Designer and downloading the edited file. If you move the downloaded file to krakend/krakend.json the server will apply the changes automatically.

The following endpoints are worth noticing:

Feature	Endpoint	Description
Simple request	`/public`	A simple request calling an internal service and returning a JSON response
Data aggregation and manipulation	`/git/{user}`	Aggregating multiple calls concurrently and manipulating some data from GitHub API
GraphQL to REST transformation	`/starwars_films/{movie_id}`	Transforming a GraphQL query into a regular REST API endpoint
Caching backend responses	`/market/cached`	Caching a backend response (based on cache headers provided by the backend)
Concurrent requests	`/market/concurrent`	Using concurrent requests to gather data from Coingecko API
Sequential calls	`/sequential`	Using sequential proxy to build a pipe of sequential calls, using values from 1st call response into 2nd call request
An aggregated requests with a failing backend	`/fail`	An example on how the `X-KrakenD-complete` header works when a backend fails on an aggregated response
JWT based Authentication	`/private/auth0`	Protects and endpoint validating JWT tokens issued by Auth0

You will find more examples with comments in config/krakend/krakend.json

Contribute!

Everyone can get started with KrakenD at this repository.

Try it out! If it doesn't help you, or you think you can add additional endpoints or middleware integrations, please open a pull request! (We may be too used to KrakenD and don't recognize what a starter demo should include.)

Thanks!

Problem starting up krakend playgound - jwt_revoke build fails

Hi,

I've tried running the playground using "docker-compose up", but it fails while building jwt_revoke. I've tried it both on my Mac and also on a CentOS virtual machine and both display the same error.

Any thoughts? Thanks

Adding __debug reference to backend results in a 500 error

I am running krackend_ce in debug mode. I have added /__debug/ to the url_pattern for the /private/custom endpoint. When I place the call to http://localhost:8080/private/custom with the debug reference, krakend_ce returns a 500 error:

krakend_ce_1       | [GIN] 2021/02/17 - 21:24:15 | 500 |     24.0597ms |      172.18.0.1 | GET      "/private/custom"
krakend_ce_1       | Error #01: Invalid status code

Here's the config for the endpoint in krakend.json:

    {
      "endpoint": "/private/custom",
      "backend": [
        {
          "url_pattern": "/__debug/user/1.json",
          "extra_config": {}
        }
      ],
      "extra_config": {
        "github.com/devopsfaith/krakend-jose/validator": {

          ],
          "roles_key": "roles",
          "issuer": "https://krakend.io",

          "disable_jwk_security": true
        }
      }
    }

What am I doing wrong?

How to read krakend.json file as remote?

There are many people working on API project. While editing KrakenD configurations, we want everyone to edit in a common area, not their own local environment. For this, we want the krakend.json file to be read from a remote server. How can I do that?

simple pass thru of index.html swagger endpoint

I am trying something similar to this issue in luraproject

Where i am trying to trigger localhost:8010/swagger/index.html which is a html page exposed by swagger-ui container.

I tried this:

"endpoints": [
    {
      "endpoint": "/swagger/",
      "output_encoding": "no-op",
      "backend": [
        {
          "url_pattern": "/swagger/",
          "encoding": "no-op",
          "host": [
            "host.docker.internal:8010"
          ]
        }
      ]
    },
    {
      "endpoint": "/swagger/{a}",
      "output_encoding": "no-op",
      "backend": [
        {
          "url_pattern": "/swagger/{a}",
          "encoding": "no-op",
          "host": [
            "host.docker.internal:8010"
          ]
        }
      ]
    },
    {
      "endpoint": "/swagger/{a}/{b}",
      "output_encoding": "no-op",
      "backend": [
        {
          "url_pattern": "/swagger/{a}/{b}",
          "encoding": "no-op",
          "host": [
            "host.docker.internal:8010"
          ]
        }
      ]
    }

FYI: I am doing a wildcard because /swagger/index.html also triggers /swagger/swagger-ui.css, /swagger/swagger-bundle.js, /swagger/swagger-ui-standalone-preset.js etc files in /swagger/* and /swagger/*/*

Can someone shed light on how to passthrough to this html file.

How do I modify the docker-compose file to start krakend-ec in debug mode?

Per this document: https://www.krakend.io/docs/endpoints/debug-endpoint/ I would like to start krakend_ce in debug mode. I've tried a few additions to the compose file, including command: ["-d"], but I've only succeeded in breaking it. :)

env variables in krakend.json failing it to load in KrakenDesigner

Hi,
I am using {{env MY_CUSTOM_ENV}} to pass env variables into my krakend.json.

Able to spinup locally, but when I export file into krakenDesigner or UI to create krakend.json it is complaining about the json format.

How can I overcome this issue? Is this known issue or am i doing it wrong?

How can I disable Auth0 integration?

I have used docker-compose up to run the krakend, but the website let me to login.

How can I disable Auth0 integration?
or how can I get these auth0 params?

var AUTH0_DOMAIN='AUTH0_DOMAIN';
var AUTH0_AUDIENCE = 'AUTH0_AUDIENCE';

Got unauthorized error

Hi,
I just install KrakenD Playground. I didn't see any other configuration, so I just started run docker-compose up and unfortunately got this error
ERROR: Get https://registry-1.docker.io/v2/jaegertracing/all-in-one/manifests/1.20: unauthorized: incorrect username or password

What can I do to solve this error?

impossible to login to :8080

running make run, I can see in the docker log:
[00] [KRAKEND] 2023/12/18 - 11:23:45.401 ▶ ERROR [SERVICE: Asyncagent][async-agent-demo] building the amqp subscriber: dial tcp 192.168.64.5:5672: connect: connection refused

I can't connect to the docker using port 8080 or 8090, I have the error:
404 page not found
I can't see anything about it in the log (make logs or container log)

ERROR writing to influx: {"code":"unauthorized","message":"unauthorized access"}

Hello,
I cloned the krakend-playground repo then ran docker-compose up in its directory, everything seemed to go ok until I hit this message spamming over and over:

I've let this run for roughly 15 minutes thinking that maybe I was waiting on something in the container to start up, but it keeps spinning. Anything I need to adjust on my end to allow it to proceed? Thanks!

Error on login Click

After click on login it shows:

The provided redirect_uri is not in the list of allowed callback URLs.
what url should be added??

Could you please let me know what I'm missing?

Can we return a flat list for collection?

When I add endpoint manipulation for the response collection, the response I getting is like:

{
    "return_collection_name": [
        { ... },
        { ... }
   ]
}

But I am expecting to get:

[
   { ... },
   { ... }
]

Shed some insights if it is possible.

kid header is required by the JWT validator

I am trying to config krakend to my local symetric key to validate incoming JWT Bearer tokens, my key.json file:

{
	"keys": [
		{
			"kty": "oct",
			"k": "123",
			"kid": "key_one",
			"alg": "HS256"

	]
}

and the config.json definition is:

what is the cause of runtime error: invalid memory address or nil pointer dereference? and how can I config my krakend to validate tokens with a local jwk?

"target" : feature not working

if i try to use target feature in krakend.json in any backend configuration file then that backend is giving an empty data i.e it is just showing {} if tried to curl apigateway/any_endpoint

Nothing at http://localhost:8080/demo

The readme mentions that there should be some static content at /demo, but this doesn't seem to work.

I see that the static-filesystem plugin is mentioned in extra_config.tmpl, but it doesn't seem to be in the active config. Also, there are no files at config/krakend/demo.

Request for syntax update

I utilize environment variables within the krakend.json configuration file. While functional, this approach does not align well with the JSON schema standards.

"version": 3,
"$schema": "https://www.krakend.io/schema/v2.6/krakend.json",
"port": {{ env "PORT_KRAKEND" }}

Could you please update this syntax?

Here's an example for you:
"port": "%PORT_KRAKEND%"

Source for env variables with JSON: https://www.genui.com/resources/env-variables-json

Does not work on arm64 MacOS

I would like to run the playground on a m1 Mac (arm64 architecture). There are two issues:

the krakend:watch image is only available as amd64. I can work around this using krakend:latest
the "fake_api" (ghcr.io/lpereira/lwan:latest) image is only available as amd64

Please update (or bake the fake_api in to the playground, or provide some suitable alternatives)
