Deployment Guide for Utho Cloud Load-Balancer Application Using Kubernetes and Helm

This document provides a step-by-step guide to configure and deploy an application on Utho Cloud using Kubernetes and Helm.

Prerequisites

• Access to the Utho Cloud UI.
• Permissions to download the kubeconfig file.
• A target server with the snap package manager installed.

Deployment Steps

Step 1: Download the kubeconfig File

1. Log in to the Utho Cloud UI.
2. Download the kubeconfig file to access your Kubernetes cluster.

Step 2: Install kubectl on Your Target Server

Install kubectl using the following command:

snap install kubectl --classic

Step 3: Export the Kubeconfig File Path

Set the kubeconfig file path to enable kubectl access to the cluster:

export KUBECONFIG=/root/kubeconfig

Step 4: Deploy the NGINX Test Application and Loadbalancer

Create a deployment.yaml file with the following content:

---
apiVersion: v1
kind: Service
metadata:
  name: test
  annotations:
    # name of the loadbalancer
    service.beta.kubernetes.io/utho-loadbalancer-name: "k8s-lb-custom-name"
spec:
  type: LoadBalancer
  selector:
    app: test
  ports:
    - name: http
      port: 80
      targetPort: 80
---
apiVersion: apps/v1
kind: Deployment
metadata:
  name: test
  labels:
    app: test
spec:
  replicas: 2
  selector:
    matchLabels:
      app: test
  template:
    metadata:
      labels:
        app: test
    spec:
      containers:
        - name: test
          image: nginx:latest
          ports:
            - name: http
              containerPort: 80
              protocol: TCP
          imagePullPolicy: Always

1. Apply the deployment:

   kubectl apply -f deployment.yaml

2. Logs for review

for pod in $(kubectl get pods -n kube-system --no-headers -o custom-columns=":metadata.name" | grep '^utho-ccm'); do echo "Logs for pod: $pod"; kubectl logs -f -n kube-system "$pod" & done

3. Check Status of Loadbalancer IP This may take upto 10 Minutes to assign loadbalancer IP.

kubectl get svc

Step 13: Verify Application Functionality

1. Check the URL and IP assigned in the Utho Cloud dashboard.
2. Access the service using the provided URL to confirm the application is running.

This concludes the deployment process for the Utho Cloud Load-Balancer.
