Private Amazon EKS Clusters and Ingress Patterns In this article, we'll explore the intricacies of private Amazon EKS clusters and ingress patterns, providing practical guidance on designing resilient multi-cluster applications. TL;DR Private EKS clusters are ideal for sensitive workloads, but require careful consideration of ingress patterns. Understanding ingress patterns is crucial for cost control, as traffic within the same AZ is generally free, while cross-AZ and inter-region traffic incurs data transfer charges. We'll discuss common pitfalls to avoid when designing private EKS clusters and ingress patterns. We'll explore the importance of using the AWS Load Balancer Controller and Application Load Balancer ingress for your EKS applications. We'll provide a checklist for setting up private EKS clusters and ingress patterns. Designing Resilient Multi-Cluster Applications When designing resilient multi-cluster applications, it's essentia...

Securing the Kubernetes Supply Chain with SLSA and SBOMs In today's complex software landscape, securing the Kubernetes supply chain is crucial to prevent vulnerabilities and ensure reliable deployments. In this article, we'll explore the importance of SLSA and SBOMs in securing your Kubernetes supply chain. TL;DR Understand the risks associated with unsecured supply chains Learn about SLSA and SBOMs and their role in securing the supply chain Discover how to implement SLSA and SBOMs in your Kubernetes environment Get practical guidance on integrating SLSA and SBOMs with your CI/CD pipeline Learn how to avoid common pitfalls and ensure a secure supply chain What is the Kubernetes Supply Chain? The Kubernetes supply chain refers to the entire process of building, deploying, and managing applications on a Kubernetes cluster. This includes the source code, dependencies, build tools, and deployment scripts. A secure supply chain ensures that all components ar...

Kubernetes Multi-Tenancy with Namespaces and Network Policies In this post, we'll explore the best practices for implementing Kubernetes multi-tenancy using namespaces and network policies. We'll cover how to configure tenant isolation, restrict Flux CD to specific namespaces, and enable self-service deployments for tenants. TL;DR Configure tenant isolation using namespaces and network policies Restrict Flux CD to specific namespaces for multi-tenant isolation Enable self-service deployments for tenants Use network policies to control cross-tenant network communication Implement namespace isolation for each tenant Configuring Tenant Isolation with Namespaces When it comes to multi-tenancy in Kubernetes, namespaces are the first line of defense. By creating a separate namespace for each tenant, you can isolate their resources and prevent unauthorized access. However, simply creating a namespace is not enough – you also need to configure network policies...
