The Complete Kubernetes Tyk Demo

The tyk-k8s-demo repository allows you to start up an entire Tyk Stack with all its dependencies as well as other tools that can integrate with Tyk. The repository will spin up everything in Kubernetes using helm and bash magic to get you started.

Purpose

Minimize the amount of effort needed to start up the Tyk infrastructure and show examples of how Tyk can be setup in k8s using different deployment architectures as well as different integrations.

Getting Started

Requirements

You will need the following tools to be able to run this library.

• Kubectl
• Helm
• jq
• git
• Terraform (only when using --cloud flag)

Tested on Linux/Unix based systems on AMD64 and ARM architectures

Initial setup

Create .env file and update the appropriate fields with your licenses. If you require a trial license, you can obtain one here. If you are looking to use the tyk-gateway deployment only you will not require any licensing as that is the open-source deployment.

git clone https://github.com/TykTechnologies/tyk-k8s-demo.git
cd tyk-k8s-demo
cp .env.example .env

Depending on the deployments you would like install set values of the LICENSE, MDCB_LICENSE and PORTAL_LICENSE inside the .env file.

Minikube

If you are deploying this on Minikube, you will need to enable the ingress addon. You can do so by running the following commands:

minikube start
minikube addons enable ingress

Quick Start

./up.sh --deployments portal,operator-httpbin tyk-stack

This quick start command will stard up the entire Tyk stack along with the Tyk Enterprise Portal, Tyk Operator and httpbin CRD example.

Possible deployments

• tyk-stack: Tyk single region self-managed deployment
• tyk-cp: Tyk self-managed multi region control plane (Will be available in Q1 2024 with new Tyk Charts. Please use the v2 tag if you would like to deploy this)
• tyk-dp: Tyk self-managed data plane, this can connect to Tyk Cloud or a Tyk Control Plane
• tyk-gateway: Tyk oss self-managed single region

Example

./up.sh \
  --storage postgres \
  --deployments prometheus-grafana,k6-slo-traffic \
  tyk-stack

The deployment will take 10 minutes, as the installation is sequential and the dependencies require a bit of time before they are started up. Once the installation is complete, the script will print out a list of all the services that were started and how those can be accessed. The k6 job will start running after the script is finished and will run in the background for 15 minutes to generate traffic over that period of time. To visualize the live traffic, you can use the credentials provided by the script to access Grafana or the Tyk Dashboard.

Usage

Start Tyk deployment

Create and start up the deployments

Usage:
./up.sh [flags] [command]

Available Commands:
tyk-stack
tyk-cp
tyk-dp
tyk-gateway

Flags:
-v, --verbose         bool     set log level to debug
--dry-run         bool     set the execution mode to dry run. This will dump the kubectl and helm commands rather than execute them
-n, --namespace       string   namespace the tyk stack will be installed in, defaults to 'tyk'
-f, --flavor          enum     k8s environment flavor. This option can be set 'openshift' and defaults to 'vanilla'
-e, --expose          enum     set this option to 'port-forward' to expose the services as port-forwards or to 'load-balancer' to expose the services as load balancers or 'ingress' which exposes services as a k8s ingress object
-r, --redis           enum     the redis mode that tyk stack will use. This option can be set 'redis', 'redis-sentinel' and defaults to 'redis-cluster'
-s, --storage         enum     database the tyk stack will use. This option can be set 'postgres' and defaults to 'mongo'
-d, --deployments     string   comma separated list of deployments to launch
-c, --cloud           enum     stand up k8s infrastructure in 'aws', 'gcp' or 'azure'. This will require Terraform and the CLIs associate with the cloud of choice
-l, --ssl             bool     enable ssl on deployments

Stop Tyk deployment

Shutdown deployment

Usage:
  ./down.sh [flags]

Flags:
  -v, --verbose         bool     set log level to debug
  -n, --namespace       string   namespace the tyk stack will be installed in, defaults to 'tyk'
  -p, --ports           bool     disconnect port connections only
  -c, --cloud           enum     tear down k8s cluster stood up

Clusters

You can get the library to create demo clusters for you on AWS, GCP, or Azure. That can be set using the --cloud flag and requires the respective cloud CLI to be installed and authorized on your system. You will also need to specify the CLUSTER_LOCATION, CLUSTER_MACHINE_TYPE, CLUSTER_NODE_COUNT and GCP_PROJECT (for GCP only) parameters in the .env file.

You can find examples of .env files here:

• AWS
• GCP
• Azure

For more information about cloud CLIs:

• AWS:
  • aws
• GCP:
  • gcloud
  • GOOGLE_APPLICATION_CREDENTIALS environment variable per google’s documentation
• Azure:
  • az

Customization

This library can also act as a guide to help you get set up with Tyk. If you just want to know how to set up a specific tool with Tyk, you can run the library with the --dry-run and --verbose flags. This will output all the commands that the library will run to stand up any installation. This can be helpful for debugging as well as figuring out what configuration options are required to set these tools up.

Furthermore, you can also add any Tyk environment variables to your .env file and those variables will be mapped to their respective Tyk deployments.

Example:

...
TYK_MDCB_SYNCWORKER_ENABLED=true
TYK_MDCB_SYNCWORKER_HASHKEYS=true
TYK_GW_SLAVEOPTIONS_SYNCHRONISERENABLED=true

Variables

The script has defaults for minimal settings in a .env file and it will give errors if something is missing. You can also add or change any Tyk environments variables in the .env file and they will be mapped to the respective extraEnvs section in the helm charts.
