Advanced Deployment

Helm chart

🧰 Prerequisites

Make sure you have:

A running Kubernetes cluster (e.g. Minikube, K3s, GKE, EKS)
kubectl and helm installed
Your working directory contains:

- backend-env.sh
- frontend-env.sh
- deploy-k8s-secret.sh

🔧 Step 1: Generate Secrets and Create Kubernetes Secrets

Run the deploy-k8s-secrets.sh script:


./deploy-k8s-secret.sh
 
➜  scripts ✗ ./deploy-k8s-secret.sh
🛠️ Running backend-env.sh
🔐 Creating backend.env.local...
Enter your database password:
✅ Sensitive data has been written to ./backend.env.local with restricted permissions.
🌱 Environment check passed.
🛠️ Running frontend-env.sh
Creating ./frontend.env.local...
Enter the FlowInquiry back-end server URL address (e.g., http://localhost or http://localhost:8080): http://localhost:8080
✅ Appended AUTH_SECRET to ./frontend.env.local.
✅ Frontend environment initialization complete.
🔐 Creating Kubernetes Secret: flowinquiry-backend-secret
secret/flowinquiry-backend-secret configured
🔐 Creating Kubernetes Secret: flowinquiry-frontend-secret
secret/flowinquiry-frontend-secret configured
✅ All secrets created successfully.

This will:

Prompt you to enter values (e.g., database password, backend URL)
Generate backend.env.local and frontend.env.local
Create two Kubernetes secrets:
- flowinquiry-backend-secret
- flowinquiry-frontend-secret

🚀 Step 2: Install the Helm Chart

From the directory containing flowinquiry-helm, run:


helm upgrade --install flowinquiry ./flowinquiry-helm
 
➜  flowinquiry-k8s ✗ helm upgrade --install flowinquiry ./flowinquiry-helm
Release "flowinquiry" has been upgraded. Happy Helming!
NAME: flowinquiry
LAST DEPLOYED: Mon May 19 17:13:12 2025
NAMESPACE: default
STATUS: deployed
REVISION: 2
TEST SUITE: None

🧪 Step 3: Check Deployment


kubectl get pods
kubectl get svc

Ensure all pods (backend, frontend, postgresql, caddy) are running and services are created.

🌐 Step 4: Access the Application

If you’re using Minikube:


minikube service caddy --url

This will give you a URL like:


http://127.0.0.1:1234

Open it in your browser to access FlowInquiry.

🧹 Step 5 (Optional): Uninstall

To remove the deployment:


helm uninstall flowinquiry
kubectl delete secret flowinquiry-backend-secret flowinquiry-frontend-secret
kubectl delete pvc --all
