Why Choose This Project?

Deploying applications in Kubernetes across multiple environments (Dev, QA, Staging, Production) often requires different configurations. Instead of maintaining separate manifests, Helm charts provide parameterized templates that can dynamically adjust values depending on the environment. This project helps teams achieve consistency, scalability, and automation in their Kubernetes deployments.

What You Get

• A Helm-based deployment framework for multi-environment setups.

• Automated Kubernetes manifests with environment-specific overrides.

• Ability to quickly promote applications from dev → staging → production.

• Seamless integration with CI/CD pipelines for automated deployments.

Key Features

Technology Stack

• Kubernetes – Orchestration platform

• Helm – Kubernetes package manager

• YAML – Configuration files

• GitHub/GitLab/Jenkins – CI/CD automation

• Docker – Container packaging

• Prometheus + Grafana – (optional) Monitoring and visualization

Cloud Services Used

• AWS EKS / GCP GKE / Azure AKS – Kubernetes clusters

• AWS S3 / GCP Cloud Storage / Azure Blob – Store Helm chart artifacts

• Secret Managers – AWS Secrets Manager / GCP Secret Manager / HashiCorp Vault

• Argo CD or Flux (optional) – GitOps integration for Helm charts

Working Flow

1. Write Helm Chart – Define templates for Deployment, Service, ConfigMaps, Secrets, Ingress, etc.

2. Prepare Values Files – Create values-dev.yaml, values-staging.yaml, and values-prod.yaml.

3. Deploy via Helm – Run helm install -f values-dev.yaml for dev, and similar for other environments.

4. Integrate with CI/CD – Automate deployment pipelines that pick environment-specific values.

5. Promote to Next Environment – Once validated in staging, promote Helm release to production.

6. Rollback if Needed – Use Helm’s rollback feature in case of deployment failure.

Main Modules

1. Helm Chart Templates – Standardized YAML for deployments, services, ingress, etc.

2. Environment Values – Different config for Dev/QA/Staging/Prod.

3. Release Management – Helm-based upgrade, rollback, and history tracking.

4. Pipeline Automation – CI/CD integration for automated Helm chart deployments.

5. Monitoring & Alerts – Integration with Prometheus & Grafana.

Security Features

• Secret Encryption – Store sensitive environment variables in Vault/Secrets Manager.

• Role-Based Access Control (RBAC) – Enforce Kubernetes RBAC for different environments.

• Namespace Isolation – Prevent cross-environment interference.

• Audit Logging – Track Helm release history and deployment logs.
