Tyk Gateway Docker

About

This repository serves as a playground to help you experiment with Tyk Gateway. It includes a Docker Compose file that allows you to quickly set up Tyk Gateway and Redis. Additionally, the repository provides several example API definitions and plugins to showcase the gateway's capabilities and help you learn some of its features.

Getting started

Requirements

These settings apply to any Tyk OSS deployment, for development as well as production environments.

  1. Redis - Tyk gateway requires a running Redis. To make an easy start this repo has a Docker Compose that spins up the gateway and Redis. If you use our docker compose, the config of the gateway is already set up to connect to the Redis service. As soon as it's up the gateway is ready to use.
  2. API definitions - This is the way to set Tyk Gateway to service your API. To quickly get from zero to a live API behind Tyk Gateway use the API definition examples under the ./apps directory.
  3. Gateway configurations - tyk.conf is set up appropriately and ready to use, including the API key to access/config the gateway via its APIs.

Project Structure

This repo has a few libraries that contain the file required to demo some of the Tyk gateway capabilities:

Option 1 - Running Full Tyk Deployment Using Docker Compose

In this section, you will spin up a full Tyk OSS Deployment Using Docker Compose

Requirements

Before you start, please install the following binaries:

Start up the deployment

Use docker-compose.yml to spin up a Tyk OSS environment with one command. This will start two services, Tyk gateway and Redis use the following command

$ docker-compose up -d

Check everything is up and running

In the example below we call the /hello endpoint using curl (you can use any HTTP client you want):

curl http://localhost:8080/hello -i

It returns the gateway's version and the connection status of Redis.

HTTP/1.1 200 OK
Content-Type: application/json
Date: Mon, 25 Jul 2022 19:16:45 GMT
Content-Length: 156

{
  "status": "pass",
  "version": "v3.2.1",
  "description": "Tyk GW",
  "details": {
    "redis": {
      "status": "pass",
      "componentType": "datastore",
      "time": "2022-07-25T19:16:16Z"
    }
  }
}

Check the loaded APIs

To get the list of APIs that Tyk gateway services, run the following:

curl http://localhost:8080/tyk/apis -H "X-Tyk-Authorization: foo"

or in VS Code in a some-file.http:

http://localhost:8080/tyk/apis
X-Tyk-Authorization: foo

The response is a JSON array of the API definitions. To beautify the list, use jq:

curl http://localhost:8080/tyk/apis -H "X-Tyk-Authorization: foo" | jq .

Notice that we used the API key (secret) to connect to the gateway. /tyk/apis is the way to configure or check the configuration of Tyk Gateway via APIs and as such it must be protected so only you can connect it.


Option 2 - Running Tyk using Docker

If you want to run docker (not docker compose), use these instructions.

For production, in which you use docker (not docker compose), check the instructions on our docs website.

Build your own Tyk Docker image

To you want to build an image yourself please use this Dockerfile


Tyk Hybrid Gateway - for paying users only!

Tyk Hybrid Gateway is the same Tyk OSS gateway but here it's connecting to a control plane layer (specifically to a component called MDCB). The control plane can be self-managed or via the SaaS offering on Tyk cloud. As such, this option can be used only by paying clients (including users that trial the paying option).

FYI Tyk cloud has also a Cloud Free plan but Hybrid gateways are not part of it.

To set up a Hybrid gateway/cluster of gateways, do the following:

  1. Change the following 3 values in the gateway config file (in this repo it is referred to as tyk.hybrid.conf:
    "slave_options": {
        "rpc_key": "<ORG_ID>",
        "api_key": "<API-KEY>",
        "connection_string": "<MDCB-INGRESS>:443",

it should look like this:

    "slave_options": {
        "rpc_key": "j3jf8as9991ad881349",
        "api_key": "adk12k9d891j48df824",
        "connection_string": "persistent-bangalore-hyb.aws-usw2.cloud-ara.tyk.io:443",
  1. Use the hybrid config file in docker compose by mounting it into the Gateway in docker-compose.yml

Change from

- ./tyk.standalone.conf:/opt/tyk-gateway/tyk.conf

To:

- ./tyk.hybrid.conf:/opt/tyk-gateway/tyk.conf

That's it! Now run docker-compose up
