+# Kubernetes Deployment Guide
+
+This repository contains a shared Helm chart (`app-chart`) that can be used to deploy multiple applications with the same architecture pattern.
+

+
+## Quick Start
+
+### Deploy Tasko Application
+
+```bash
+# Install
+helm install tasko ./app-chart -f tasko/values.yaml -n my-apps --create-namespace
+
+# Upgrade
+helm upgrade tasko ./app-chart -f tasko/values.yaml -n my-apps
+
+# Uninstall
+helm uninstall tasko -n my-apps
+```
+
+### Deploy My-Recipes Application
+
+```bash
+# Install
+helm install my-recipes ./app-chart -f my-recipes/values.yaml -n my-apps --create-namespace
+
+# Upgrade
+helm upgrade my-recipes ./app-chart -f my-recipes/values.yaml -n my-apps
+
+# Uninstall
+helm uninstall my-recipes -n my-apps
+```
+
+## Application URLs
+
+### Tasko
+- Frontend: https://tasko.dvirlabs.com
+- Backend API: https://api-tasko.dvirlabs.com
+
+### My-Recipes
+- Frontend: https://my-recipes.dvirlabs.com
+- Backend API: https://api-my-recipes.dvirlabs.com
+
+## Adding a New Application
+
+1. **Create application directory**:
+   ```bash
+   mkdir <app-name>
+   ```
+
+2. **Create `<app-name>/values.yaml`**:
+   ```yaml
+   global:
+     namespace: my-apps
+
+   backend:
+     image:
+       repository: harbor.dvirlabs.com/my-apps/<app-name>-backend
+       tag: "latest"
+     service:
+       port: 8000
+       targetPort: 8000
+     ingress:
+       hosts:
+         - host: api-<app-name>.dvirlabs.com
+           paths:
+             - path: /
+               pathType: Prefix
+       tls:
+         - secretName: api-<app-name>-tls
+           hosts:
+             - api-<app-name>.dvirlabs.com
+
+   frontend:
+     image:
+       repository: harbor.dvirlabs.com/my-apps/<app-name>-frontend
+       tag: "latest"
+     env:
+       VITE_API_URL: "https://api-<app-name>.dvirlabs.com"
+     ingress:
+       hosts:
+         - host: <app-name>.dvirlabs.com
+           paths:
+             - path: /
+               pathType: Prefix
+       tls:
+         - secretName: <app-name>-tls
+           hosts:
+             - <app-name>.dvirlabs.com
+
+   postgres:
+     user: <app-name>_user
+     password: <secure-password>
+     database: <app-name>_db
+   ```
+
+3. **Create `<app-name>/cname.yaml`**:
+   ```yaml
+   apiVersion: v1
+   kind: ConfigMap
+   metadata:
+     name: <app-name>-cname
+     namespace: my-apps
+   data:
+     frontend: <app-name>.dvirlabs.com
+     backend: api-<app-name>.dvirlabs.com
+   ```
+
+4. **Deploy**:
+   ```bash
+   helm install <app-name> ./app-chart -f <app-name>/values.yaml -n my-apps
+   ```
+
+## Configuration
+
+Each application can override the base configuration by providing custom values in their `values.yaml` file. Common overrides include:
+
+- Image repository and tags
+- Resource limits and requests
+- Environment variables
+- Ingress hostnames
+- Database credentials
+- Replica counts
+
+See `app-chart/README.md` for detailed configuration options.
+
+## Prerequisites
+
+- Kubernetes cluster (1.19+)
+- Helm 3.0+
+- Traefik Ingress Controller installed
+- cert-manager installed (for automatic TLS certificates)
+- kubectl configured to access your cluster
+
+## DNS Configuration
+
+Configure DNS records to point to your ingress controller:
+
+```
+<app-name>.dvirlabs.com       CNAME/A    <ingress-loadbalancer-ip>
+api-<app-name>.dvirlabs.com   CNAME/A    <ingress-loadbalancer-ip>
+```
+
+## Monitoring Deployments
+
+```bash
+# Check all deployments
+kubectl get all -n my-apps
+
+# Check specific application
+kubectl get pods -n my-apps -l app.kubernetes.io/instance=tasko
+
+# View logs
+kubectl logs -n my-apps -l component=backend --tail=100 -f
+kubectl logs -n my-apps -l component=frontend --tail=100 -f
+
+# Check ingress
+kubectl get ingress -n my-apps
+```
+
+## Database Management
+
+### Access PostgreSQL
+
+```bash
+# Port forward to access database locally
+kubectl port-forward -n my-apps svc/tasko-db 5432:5432
+
+# Connect using psql
+psql postgresql://tasko_user:tasko_password@localhost:5432/tasko_db
+```
+
+### Backup Database
+
+```bash
+# Backup
+kubectl exec -n my-apps tasko-db-0 -- pg_dump -U tasko_user tasko_db > backup.sql
+
+# Restore
+kubectl exec -i -n my-apps tasko-db-0 -- psql -U tasko_user tasko_db < backup.sql
+```
+
+## CI/CD Integration
+
+The chart works seamlessly with CI/CD pipelines. Example with Woodpecker CI:
+
+```yaml
+steps:
+  deploy:
+    image: alpine/helm:3.12.0
+    commands:
+      - helm upgrade --install tasko ./app-chart 
+        -f tasko/values.yaml 
+        --set backend.image.tag=${CI_COMMIT_SHA}
+        --set frontend.image.tag=${CI_COMMIT_SHA}
+        -n my-apps
+```
+
+## Troubleshooting
+
+### Pod not starting
+```bash
+kubectl describe pod -n my-apps <pod-name>
+kubectl logs -n my-apps <pod-name>
+```
+
+### Database connection issues
+```bash
+# Check if database is running
+kubectl get pods -n my-apps -l component=database
+
+# Test connection from backend pod
+kubectl exec -n my-apps <backend-pod> -- env | grep DB_
+```
+
+### Ingress not working
+```bash
+# Check ingress configuration
+kubectl describe ingress -n my-apps <app-name>-backend
+kubectl describe ingress -n my-apps <app-name>-frontend
+
+# Check cert-manager certificates
+kubectl get certificate -n my-apps
+kubectl describe certificate -n my-apps <app-name>-tls
+```
+
+## Migration from Old Chart
+
+If migrating from the old `my-recipes-chart`:
+
+1. **Backup your data**
+2. **Update DNS** if hostnames changed
+3. **Deploy with new chart**:
+   ```bash
+   helm uninstall my-recipes  # Old release
+   helm install my-recipes ./app-chart -f my-recipes/values.yaml -n my-apps
+   ```
+
+## Support
+
+For detailed documentation, see:
+- `app-chart/README.md` - Complete chart documentation
+- `helm/README.md` - Docker image building and deployment
+
+For issues and questions, please open an issue in the repository.
