Run Airy on minikube

Run Airy on minikube with one command.

The goal of this document is to provide an overview of how to run Airy Core on your local machine using minikube.

Install​

note

By default the UI and the API will be available at http://localhost. Make sure you don't have any other process using port 80 on your localhost interface

First install minikube using their documentation. Minikube version v1.19.0 or higher is required.

Next you also need to install the Airy CLI. Now you can run this command, which will create a new minikube cluster on your system and install Airy core on it:

airy create --provider=minikube my-airy

This will execute the following actions:

  1. Create the my-airy directory and populate it with the configuration that the CLI will need. All subsequent commands need to either be run from this directory or use the --workspace flag.
  2. Fetch the required Terraform modules in the terraform subdirectory, including the install.sh and uninstall.sh scripts.
  3. Run the install.sh script
  4. Start a minikube cluster on your system using Terraform, under the profile airy-core.
  5. Install the Airy Core helm chart on the minikube instance using Terraform (in a separate Terraform state then the minikube instance).
  6. Print the resulting URLs on which you can access the Airy Core installation and some additional information.
note

The base URL for the API is the same to access the UI through your browser. You can use the printed ngrok URL to connect to different sources to the instance running on your local machine.

To customize your Minikube instance, you can adjust the driver, cpus and memory attributes in the following manner:

airy create --provider=minikube --provider-config driver=virtualbox,cpus=4,memory=8192 my-airy

If you want to customize your Airy Core instance please see our Configuration Section.

After the installation, you can also interact with the components of Airy Core with the kubectl command line utility. airy create creates the kubeconfig file kube.conf under the terraform directory in your workspace.

note

If the airy create command fails and you have installed a hypervisor for the first time, double-check that you have given it all the necessary permissions on your local machine. More information will be printed in the output from the Terraform installation.

Configure​

For more details on configuring your Airy Core instance please see our Configuration Section. Under the tools section you can also find information on installing and activating third party tools for more detailed Kafka and data debugging.

Integrate public webhooks​

In order to integrate with the webhook of most sources on your local machine, we include a ngrok as a deployment to tunnel the traffic to the ingress controller. ngrok is an open source reverse proxy which creates a secure tunnel from a public endpoint to a local service. The ngrok client connects to a ngrok server which has public access to the internet and then provides a reversed proxy connectivity back to the webhook services, running inside the Kubernetes cluster.

To get the ngrok URL of your local Airy Core installation you can run:

export KUBECONFIG=./terraform/kube.conf
echo "https://$(minikube -p airy-core kubectl -- get cm core-config -o jsonpath='{.data.CORE_ID}').tunnel.airy.co"

By default, the ngrok client is configured to use the ngrok server created by Airy and runs on https://tunnel.airy.co. This configuration is specified in the ngrok-client-config ConfigMap.

apiVersion: v1
kind: ConfigMap
metadata:
  name: ngrok-client-config
  namespace: default
data:
  config.yml: |
    server_addr: proxy.tunnel.airy.co:4443
    trust_host_root_certs: true

If you prefer to use your own ngrok implementation or point the ngrok client to connect to the service provided by the ngrok company at https://ngrok.io, change the setting for server_addr in the ConfigMap.

Next steps​

Now that you have a running local installation of minikube you can connect it to messaging sources. Check out our Quickstart guide to learn more:

Uninstall​

To uninstall Airy Core from AWS, run the uninstall.sh script located in the WORKSPACE/terraform directory. This script will run terraform destroy on both the kubernetes (minikube) and the airy-core state.

cd terraform
./uninstall.sh

Deleting the minikube instance also removes Airy completely from your system:

minikube -p airy-core delete
