Connecting to Amazon Kubernetes Cluster and Port Forwarding Argocd and Airflow Web Server

This guide will walk you through the process of connecting to your Amazon Kubernetes Service (AKS) cluster using the Aws CLI and then port forwarding the Arogcd and Airflow web server for local access.

Prerequisites

  • AWS CLI installed on your local machine.
  • The Kubernetes command-line tool kubectl which allows you to run commands against Kubernetes clusters.

Steps

1.Install and Configure AWS CLI:

If you haven't already, you'll need to install and configure the AWS CLI. You can download and set it up by following the instructions in the AWS CLI install instructions.

2.Configure Kubernetes CLI (kubectl):

To interact with an Amazon Elastic Kubernetes Service (EKS) cluster, you need to fetch the cluster's configuration. You can do this with the AWS CLI:

aws eks update-kubeconfig --name <cluster_name> --region <region>

Replace <cluster_name>, with the actual name and region of your EKS cluster.

Port Forwarding the Argocd Server

To port forward the argocd web server to your local machine, use the kubectl port-forward command. Replace and with the name of the Argocd server service and with the local port you want to use (e.g., 8080):

## This is the format of the port fowarding command
kubectl port-forward -n <namespace> svc/<service-name> <local-port>:80
kubectl port-forward -n argocd svc/argocd-server 8080:80

1. Access the Argocd Web UI:

You will see a message similar to:

Forwarding from 127.0.0.1:8080 -> 8080

Let's open the port displayed in the browser:

eg: http://127.0.0.1:8080

You should now see a login page for Argocd, and a place to enter a username and password. The username is admin and the password is available in the .env file we created for you under the key ARGOCD_ADMIN_PASSWORD.

2. Terminating the Port Forwarding Session:

To terminate the port forwarding session, simply press Ctrl+C in your terminal when you're done using the Argocd web UI.

Port Forwarding the Airflow WebServer

To port forward the Airflow web server to your local machine, use the kubectl port-forward command. Replace and with the name of the Airflow namespace, Airflow webserver service and with the local port you want to use (e.g., 8081):

kubectl port-forward -n <namespace> svc/<service-name> <local-port>:8080
kubectl port-forward -n airflow svc/airflow-webserver 8081:8080

You will see a message similar to:

Forwarding from 127.0.0.1:<local-port> -> 8080

1. Access the Airflow Web UI:

Let's open the port displayed in the browser:

eg: http://127.0.0.1:<local-port>

Open your web browser and go to http://localhost:8081 to access the Airflow web interface.

You should now see a login page for airflow, and a place to enter a username and password. The username is admin and the password is admin

2. Terminating the Port Forwarding Session:

To terminate the port forwarding session, simply press Ctrl+C in your terminal when you're done using the Airflow web UI.
