Using Amazon EBS snapshots for persistent storage with your Amazon EKS cluster by leveraging add-ons

Using Amazon EBS snapshots for persistent storage with your Amazon EKS cluster by leveraging add-ons

Originally, containers were a great fit for stateless applications. However, for many use cases there is a need for persistent storage, without which stateful workloads aren’t possible. Kubernetes first introduced support for stateful workloads with in-tree volume plugins, meaning that the plugin code was part of the core Kubernetes code and shipped with the Kubernetes […]

Using CDK to perform continuous deployments in multi-region Kubernetes environments

Policy management in Amazon EKS using jsPolicy

Introduction jsPolicy is an open-source framework for managing validating or mutating admission control policies for Amazon Elastic Kubernetes Service (Amazon EKS) clusters using JavaScript (or TypeScript), which is similar to the way AWS Identity and Access Management (IAM) manages AWS accounts and resource access. It’s also possible to write the entire jsPolicy in a separate file and […]
