…ble (staging/prod), added secure secret handling (K8s Secrets, service accounts, network policies), and standardized container builds. I enabled observability (health probes, metrics, basic alerts) and refined app code (env‑based config, validated uploads) to improve security, reliability, and scalability going forward. feat: Add Helm chart templates for EchoNet deployment - Created Kubernetes Service for model-server. - Added MongoDB credentials as a Kubernetes Secret. - Implemented MQTT deployment and service configurations. - Defined a staging namespace for EchoNet. - Established network policies for enhanced security. - Created service accounts for model-server, API, and engine. - Added ServiceMonitors for API and model-server for monitoring. - Implemented a simulator deployment and service. - Added production and staging values files for Helm chart. - Created sample parameters for GCP deployment. - Added Terraform configuration for GCP infrastructure. - Included a script for discovering EchoNet endpoints on GCP. - Updated Dockerfile for API component to improve efficiency. - Modified echo_config.json to use environment variables for DB credentials. - Enhanced error handling in main.py for better API resilience. - Updated audio upload router to include file validation. - Improved .dockerignore files for API and HMI components. - Refactored environment variables in Kubernetes ConfigMaps to use Secrets. - Updated MongoDB initialization script to use environment variables for credentials. - Modified HMI configuration to utilize environment variables for database connection.

Goal
Migrate Project Echo’s backend infrastructure from Docker-based deployment to a cloud-native platform using Kubernetes and Helm, enabling scalable, maintainable, and production-ready deployments.
What I built
1. Helm Chart Structure
Created a comprehensive Helm chart in echonet for modular cloud deployment.
Defined Chart.yaml for chart metadata and dependencies.
2. Environment Configuration
Provided three values files:
values.yaml (default)
values-prod.yaml (production)
values-staging.yaml (staging)
These files allow environment-specific overrides for resources, image tags, secrets, and service endpoints.
3. Kubernetes Manifests (Templates)
Deployments: Separate deployment manifests for API, engine, HMI, model server, simulator, and MQTT.
Services: Each major component has a corresponding service manifest for internal/external access.
Secrets: mongo-credentials-secret.yaml secures database credentials.
ConfigMaps: model-config-configmap.yaml for model server configuration.
Network Policies: networkpolicies.yaml restricts traffic for security.
Service Accounts: serviceaccount-model.yaml for RBAC and pod identity.
Monitoring: servicemonitors.yaml for Prometheus integration.
Ingress: ingress.yaml for HTTP routing and external access.
Namespace: namespace-staging.yaml for environment isolation.
Alerts: alerts.yaml for monitoring and alerting rules.
4. CI/CD Integration
build-engine-model.yaml (current file) likely automates build and deployment steps for cloud infrastructure.
Comamand for test
helm lint deploy/helm/echonet
helm install echonet-staging deploy/helm/echonet -f deploy/helm/echonet/values-staging.yaml --dry-run
kubectl apply -f deploy/helm/echonet/templates/
