Enterprises in EKS Extended Support and GKE Extended Support are setting themselves up for Forced Upgrades—an extreme, unavoidable, and disruptive event that creates business continuity risks. When Extended Support ends, organizations have no choice but to rush an AWS EKS upgrade or to upgrade a GKE cluster, often leading to breakages and application disruptions. While some businesses have bought time by paying up to 6X in Extended Support fees for EKS and GKE, this only postpones the inevitable. The longer they wait, the harder the upgrade becomes.?#Kubernetes?upgrades don’t have to be this painful, but?without planning, forced upgrades will become a reality. Here are the key risks and challenges: 1/ Forced Upgrades disrupt the entire system 2/ Hidden dependencies wreak havoc 3/ Addons stop working without warning 4/ Deprecated features cause breakages 5/ Months of labor-intensive prep work is required every time 6/ Outdated EKS and GKE versions cost 6X more 7/ Security vulnerabilities go unpatched 8/ Compliance becomes impossible 9/ Operational inefficiencies due to legacy components 10/ There is a financial impact of ignoring EOL versions Let’s dive into each.. ?? Forced Upgrades Disrupt the Entire System When enterprises delay upgrades for too long, they reach a point where even the?#EKS Extended Support?or?#GKE Extended Support?expires, leaving them with no option but to upgrade under pressure. These last-minute upgrades are untested, rushed, and highly disruptive. Organizations without a rollback plan often find themselves firefighting for weeks as they attempt to fix broken workloads. This could result in lost productivity, customer dissatisfaction, and substantial revenue losses. ?? Hidden Dependencies Wreak Havoc The core problem with Kubernetes upgrades isn’t the control plane—it’s the vast network of addon dependencies. Enterprises run hundreds of addons, each with its own upgrade schedule, compatibility requirements, and hidden dependencies. Since many of these dependencies are undocumented, even a minor update can create a?cascading failure across the system. Without proper tools to track dependencies, any GKE or EKS cluster upgrade is an unsafe operation, leaving teams scrambling to debug failures that should have been anticipated.

Kubernetes Admission Controllers act as your cluster’s “checkpoint.” They intercept API requests, enforce best practices, and secure your environment before objects are persisted to etcd. Our latest blog outlines common pitfalls and misconfigurations, such as: ?? Idempotency: Ensure mutating webhooks can safely run multiple times without unexpected changes. ?? Availability: Use short timeouts and load-balancing to keep webhook responses fast. ?? Validating the Final State: Employ validating webhooks to confirm objects match desired configurations. ?? Protecting kube-system: Avoid mutating or rejecting requests in the kube-system namespace. Read more here: https://lnkd.in/gUTbMmsM #kubernetes #k8s #sre #cloudcomputing

Pod Disruption Budgets: Pitfalls, Evictions & Kubernetes Upgrades! Pod Disruption Budgets (PDBs) can save your Kubernetes apps from downtime—but only if they’re set up correctly. Our latest blog covers the most common pitfalls and misconfigurations, including: ?? UpgradeFailed errors due to eviction failures: Occurs when a pod is protected by a restrictive PDB policy, preventing it from being drained. ?? Overly restrictive PDBs: Setting maxUnavailable=0 or minAvailable=100% can block node draining. ?? Arbitrary workload selectors and empty selectors: Leading to unexpected coverage or none at all. ?? False sense of guaranteed availability: A disruption budget doesn’t ensure the specified number/percentage of pods will always be up.

?? Outdated Kubernetes versions could cost you big! Running outdated versions on Amazon EKS, Google GKE, and Azure AKS can lead to non-compliance, security risks, and surcharges up to 500% higher. These business drivers require Platform teams to upgrade each cluster and its add-ons at least 2-3 times/year. Failure to upgrade by deadlines can lead to severe disruptions–for instance, cloud providers may force-upgrade clusters, potentially leading to unplanned downtime, impacting mission-critical applications. ? Don't worry, Chkk has your back! Chkk ensures you stay within support windows with timely, risk-free upgrades, helping you remain compliant and avoid costly surprises.
