AWS EKS Support
AWS EKS support, troubleshooting and optimization.
Amazon EKS takes care of the Kubernetes control plane, but node groups, networking, add-ons, upgrades and cost control are still yours to run.
Common EKS problems we fix
The Amazon EKS issues our engineers see most often, and how we resolve them.
EKS pods stuck in Pending or CrashLoopBackOff
Pending pods usually mean insufficient node capacity, unschedulable taints or exhausted pod IPs. CrashLoopBackOff points at the application, probes or resource limits. We use events, logs and node metrics to find the cause.
EKS worker nodes NotReady or cannot join the cluster
Node join failures come from a wrong aws-auth or access entry mapping, missing IAM policies, VPC CNI problems or blocked access to the API endpoint. We correct the role mapping, networking and bootstrap settings.
EKS version upgrade planning
Upgrades fail when deprecated APIs, incompatible add-ons or old node AMIs are ignored. We audit manifests and add-ons, upgrade the control plane, node groups and add-ons in order, and test before cutting production over.
EKS cost optimization
Over-provisioned nodes, idle clusters, NAT data charges and missing autoscaling drive cost. We introduce Karpenter or Cluster Autoscaler, right-size requests and limits, use Spot and Graviton nodes and consolidate clusters.
Pod networking and load balancer problems
IP exhaustion from the VPC CNI, security groups for pods and misconfigured AWS Load Balancer Controller annotations are common. We fix subnet sizing, CNI settings and ingress configuration.
How We Help With EKS
Senior AWS engineers who explain what they change and why.
What we do
- Cluster design, networking and security baseline
- Safe version upgrades and add-on management
- Autoscaling with Karpenter or Cluster Autoscaler
- Observability, GitOps and cost controls
How it works
- Tell us what is wrong or what you want to improve
- We review with read-only access first
- We fix, explain and document the change
- We hand off with monitoring so it stays fixed
Specialized EKS support
Deep-dive help for specific EKS tasks.
EKS cost optimization with KarpenterCut Amazon EKS costs with Karpenter, right-sized requests, Spot and Graviton nodes. TwinTix implements and tunes autoscaling without hurting reliability.
EKS version upgrade: plan, test and run it without downtimeUpgrade Amazon EKS without downtime. TwinTix checks deprecated APIs, add-ons and node groups, then runs the control plane and node upgrade in order.
EKS pods stuck Pending or in CrashLoopBackOff: causes and fixesTroubleshoot EKS pods stuck Pending, CrashLoopBackOff or ImagePullBackOff. TwinTix reads events, logs and node capacity to find and fix the cause.
EKS IRSA vs EKS Pod Identity: pick one and set it up correctlyGive EKS pods least-privilege AWS access. TwinTix compares IRSA and EKS Pod Identity, sets up roles and trust policies, and fixes AccessDenied errors.
EKS VPC CNI IP exhaustion: fix pod IP and max-pods limitsOut of pod IPs on EKS? TwinTix fixes subnet exhaustion and max-pods limits with prefix delegation, custom networking, warm pool tuning and IPv6 options.
Frequently Asked Questions
How often do I need to upgrade EKS?
Kubernetes versions leave standard support roughly 14 months after release, so most teams upgrade at least once a year. We plan and execute upgrades with rollbacks ready.
Can you reduce our EKS bill?
Usually yes: right-sizing pod requests, node consolidation, Spot and Graviton nodes and removing idle environments are the main levers.
Do you help secure EKS clusters?
Yes. We review IAM roles for service accounts, network policies, pod security, image scanning and control plane logging.
