An overview of the GetInfra modules:

1. Kubernetes (K8s) Module:

• Purpose: The Kubernetes module simplifies the process of setting up, managing, and maintaining Kubernetes clusters.
• Features:
  • Automates the deployment of a production-ready Kubernetes environment.
  • Provides customizable settings to scale based on workload needs.
  • Supports integrations with service mesh tools and monitoring systems.
  • Cloud-specific infrastructure (e.g., AWS, GCP, Azure, OVH)

2. Istio Module:

• Purpose: The Istio module integrates service mesh functionality for secure service-to-service communication, observability, and resilience.
• Features:
  • Enables traffic routing, load balancing, and fault tolerance.
  • Provides observability through service metrics and distributed tracing.
  • Offers mutual TLS (mTLS) encryption between services for security.
  • Easily configurable to include advanced features like canary deployments or blue-green deployments.

3. Cert-Manager Module:

• Purpose: The Cert-Manager module automates the management and renewal of SSL/TLS certificates.
• Features:
  • Automatically issues certificates from Certificate Authorities (CAs) like Let's Encrypt.
  • Manages lifecycle tasks such as certificate renewal and re-issuance.
  • Integrates seamlessly with ingress controllers to secure network traffic using HTTPS.

4. Let’s Encrypt Integration:

• Purpose: Let’s Encrypt integration within Cert-Manager simplifies the automation of issuing free SSL certificates.
• Features:
  • Provides zero-cost SSL/TLS certificates for securing Kubernetes services.
  • Automatically renews certificates before expiration, ensuring no service interruptions.
  • Reduces operational overhead for managing SSL/TLS certificates in production environments.

5. Kiali Module:

• Purpose: The Kiali module provides an intuitive dashboard for visualizing service mesh topology and managing Istio configurations.
• Features:
  • Offers real-time insights into service-to-service communication.
  • Visualizes traffic flows, performance metrics, and service dependencies.
  • Helps identify potential issues in microservices by surfacing error rates, response times, and request failures.
  • Simplifies troubleshooting and optimization of service mesh behavior.

6. Prometheus Module:

• Purpose: The Prometheus module facilitates robust metrics collection and alerting for monitoring the health of Kubernetes clusters and services.
• Features:
  • Collects and stores time-series metrics data from cluster nodes and applications.
  • Supports custom alerting rules to notify teams of potential issues (e.g., high CPU usage, memory leaks).
  • Easily integrates with Grafana for rich visualizations of cluster health and service performance.

7. Grafana Module:

• Purpose: The Grafana module provides a powerful platform for visualizing metrics collected by Prometheus and other sources.
• Features:
  • Creates custom dashboards for monitoring the health and performance of Kubernetes clusters, applications, and services.
  • Enables real-time data exploration and visualization.
  • Offers flexible options for alerting and notifications based on metric thresholds.
  • Supports integrations with a wide range of data sources beyond Prometheus.

8. Kyverno (Pro):

• Purpose: Kyverno is a Kubernetes-native policy engine that enables users to define and enforce security, compliance, and operational policies using familiar YAML syntax.
• Features:
  • Policy-Based Governance: Enforce best practices and security controls with customizable policies (e.g., block privileged pods, enforce labels).
  • Automated Resource Mutation: Automatically inject default configurations like resource limits or sidecars without modifying source manifests.
  • Audit and Reporting: Continuously monitor policy violations and generate audit reports for compliance visibility.

9. MinIO (Pro):

• Purpose: MinIO is a high-performance, S3-compatible object storage solution ideal for cloud-native workloads, backups, and data archiving in Kubernetes.
• Features:
  • S3-Compatible API: Seamlessly integrates with tools expecting AWS S3, including backup tools like Velero.
  • High Availability: Supports distributed mode for redundancy and fault tolerance.
  • Secure by Default: Includes TLS support, encryption, and access policies for data protection.

10. Velero (Pro):

• Purpose: Velero is a backup and recovery tool for Kubernetes, enabling safe cluster data protection, disaster recovery, and migration.
• Features:
  • Scheduled Backups: Automate backup of cluster resources and persistent volumes to supported object storage (e.g., MinIO).
  • Namespace and Label Scoping: Fine-grained control over what gets backed up or restored.
  • Disaster Recovery: Simplify restoring applications and infrastructure in the event of failure or migration.

These modules work in harmony to provide a comprehensive infrastructure setup that simplifies deployment, enhances observability, and automates security management for Kubernetes-based environments.
