Production-Grade Kubernetes Template

This repository provides a comprehensive Kubernetes environment template designed for production deployments. It incorporates best practices for security, scalability, observability, and reliability, aligned with industry standards and DevOps principles.

Overview

Following the guidelines from the DevOps Signal Projects, this template includes:

• Namespace & Resource Quotas
• Network Policies
• Pod Security Standards
• TLS Ingress with Cert-Manager
• Autoscaling (HPA, VPA)
• Self-Healing Probes
• Observability integrations (Prometheus, Grafana, Loki, Tempo)
• Disaster Recovery configurations

Features

• Isolated namespaces with resource limits
• Secure network segmentation
• Enforced security policies
• Automated TLS certificate provisioning
• Dynamic autoscaling
• Health checks and auto-healing
• Monitoring & alerting integrations

Getting Started

Prerequisites

• Kubernetes 1.20+
• Helm 3
• Cert-Manager installed (Instructions)
• Prometheus & Grafana (Helm charts)
• Access to a cloud provider or local cluster

Deployment Steps

1. Clone this repository:

git clone https://github.com/yourusername/prod-k8s-template.git
cd prod-k8s-template

2. Apply Namespace and Resource Quotas:

kubectl apply -f k8s/namespaces/production-namespace.yaml
kubectl apply -f k8s/namespaces/resource-quotas.yaml

3. Set up Pod Security Policies:

kubectl apply -f k8s/security/pod-security-policy.yaml

4. Configure Network Policies:

kubectl apply -f k8s/network/network-policy.yaml

5. Install Cert-Manager and apply ingress with TLS:

kubectl apply -f k8s/ingress/cert-manager-issuer.yaml
kubectl apply -f k8s/ingress/ingress.yaml

6. Deploy autoscaling:

kubectl apply -f k8s/autoscaling/hpa.yaml

7. Set up observability tools:

# Using Helm
helm install prometheus prometheus-community/kube-prometheus-stack -f k8s/observability/prometheus-values.yaml
