In this post, we’ll illustrate an enterprise IT scenario in which VPCs are overseen by a central network team, including configuration of VPC resources such as IP allocation, route policies, internet gateways, NAT gateways, security groups, peering, and on-premises connectivity. The network account, which serves as the owner of the centralized VPC, shares subnets with a participant application account managed by a platform team, both of which are part of the same organization. In this use case, the platform team owns the management of Amazon EKS cluster. We’ll also cover the key considerations of using shared subnets in Amazon EKS... View the full article

Kubernetes has two base node roles: supervisors and workers. A cluster may have additional roles derived from the “worker” role based on their unique infrastructure characteristics (e.g., type of CPU, NICs, GPUs, FPGAs, etc.) or the applications they run (e.g., infrastructure services, developers, development team, etc.). The supervisor nodes comprise the Kubernetes control plane, which hosts components that make cluster-level decisions. These include scheduling, responding to nodes' events, storing artifacts of all cluster-level objects from application manifests and ServiceAccounts definitions to Secrets and extensions to Kubernetes APIs in the form of CustomResourceDefinitions, and much more.

At some point during the OpenShift deployment phase, a question about project onboarding comes up, "How can a new customer or tenant be onboarded so they can deploy their own workload onto the cluster(s)?" While there are different ways from a process perspective (Service Now, Jira, etc.), I focus on the Kubernetes objects that must be created on each cluster. In A Guide to GitOps and Argo CD with RBAC, I described setting up GitOps RBAC rules so tenants can work with their (and only their) projects. This article demonstrates another possibility for deploying per tenant and per cluster ... View the full article

The Amazon Elastic Kubernetes Service (Amazon EKS) team is pleased to announce support for Kubernetes version 1.28 for Amazon EKS and Amazon EKS Distro. Amazon EKS Anywhere (release 0.18.0) also supports Kubernetes 1.28. The theme for this version was chosen as a play on words that combines plant and Kubernetes to evoke the image of a garden. Hence, the fitting release name, Planternetes. In their official release announcement, the Kubernetes release team said this of the release, “people behind this release come from a wide range of backgrounds.” View the full article

A GitOps tool like Argo CD can help centralize the automation, installation, and configuration of services onto multiple Kubernetes clusters. Rather than apply changes using a Kubernetes CLI or CI/CD, a GitOps workflow detects changes in version control and applies the changes automatically in the cluster. You can use a GitOps workflow to deploy and manage changes to a Consul cluster, while orchestrating the configuration of Consul service mesh for peering, network policy, and gateways. This approach to managing your Consul cluster and configuration has two benefits. First, a GitOps tool handles the order-of-operations and automation of cluster updates before configuration updates. Second, your Consul configuration uses version control as a source of truth that GitOps enforces across multiple Kubernetes clusters. This post demonstrates a GitOps workflow for deploying a Consul cluster, configuring its service mesh, and upgrading its server with Argo CD. Argo CD annotations for sync waves and resource hooks enable orchestration of Consul cluster deployment followed by service mesh configuration with Custom Resource Definitions (CRDs). Updating a Consul cluster on Kubernetes involves opening a pull request with changes to Helm chart values or CRDs and merging it. Argo CD synchronizes the configuration to match version control and handles the order of operations when applying the changes... View the full article

MicroShift is a minimal k8s (Kubernetes) distro, which runs preferably on ostree-based deployments. Ostree is great for edge deployment as it enables immutable (read-only) operating systems, transactional updates, over-the-air delta updates and more. Ostree tooling can ingest artifacts like rpm packages, container images, and OS customizations such as users and services. Adding MicroShift to this is easy and well documented, as MicroShift itself is made out of rpm packages and container images. View the full article -
The kubeadm tool now supports etcd learner mode, which allows you to enhance the resilience and stability of your Kubernetes clusters by leveraging the learner mode feature introduced in etcd version 3.4. This guide will walk you through using etcd learner mode with kubeadm. By default, kubeadm runs a local etcd instance on each control plane node. In v1.27, kubeadm introduced a new feature gate EtcdLearnerMode. With this feature gate enabled, when joining a new control plane node, a new etcd member will be created as a learner and promoted to a voting member only after the etcd data are fully aligned...

Kubernetes v1.25 introduced support for user namespaces for only stateless pods. Kubernetes 1.28 lifted that restriction, after some design changes were done in 1.27. The beauty of this feature is that: it is trivial to adopt (you just need to set a bool in the pod spec) doesn't need any changes for most applications improves security by drastically enhancing the isolation of containers and mitigating CVEs rated HIGH and CRITICAL. This post explains the basics of user namespaces and also shows: the changes that arrived in the recent Kubernetes v1.28 release a demo of a vulnerability rated as HIGH that is not exploitable with user namespaces the runtime requirements to use this feature what you can expect in future releases regarding user namespaces.

The Kubernetes development cycle is an evolving landscape with a myriad of tools seeking to streamline the process. Each tool has its unique approach, and the choice often comes down to individual project requirements, the team's expertise, and the preferred workflow. Among the various solutions, a category we dubbed “Local K8S Development tools” has emerged, which seeks to enhance the Kubernetes development experience by connecting locally running components to the Kubernetes cluster. This facilitates rapid testing of new code in cloud conditions, circumventing the traditional cycle of Dockerization, CI, and deployment. In this post, we compare three solutions in this category: Telepresence, Gefyra, and our own contender, mirrord... View the full article
