Advisory guidance for Amazon EKS architecture and configuration — compute strategy, networking, security, reliability, cost, autoscaling, observability, multi-tenancy, upgrade planning, on-prem/hybrid (EKS Hybrid Nodes, EKS Anywhere, Outposts), and surge readiness for planned traffic peaks. Also answers terraform-aws-modules/terraform-aws-eks questions. Use for any EKS planning or architectural judgment call, even phrased casually. Do NOT use for generating documents or code…

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# EKS Best Practices

Comprehensive guidance for designing, deploying, and operating Amazon EKS clusters. Consolidates guidance from the AWS EKS Best Practices Guide, AWS EKS HA/Resiliency Guide, and terraform-aws-modules/terraform-aws-eks examples.

## When to Use This Skill

**Activate this skill when:**
- Designing a new EKS cluster architecture
- Choosing between EKS compute options (Fargate, MNG, Karpenter, Auto Mode)
- Configuring EKS networking (VPC CNI, ingress, service mesh)
- Implementing EKS security (IAM, pod security, secrets)
- Setting up security operations (staying informed, patch cadence, emergency fixes, build hygiene, event response shape)
- Planning cluster upgrades or migrations
- Reviewing EKS architecture decisions
- Working with terraform-aws-modules/terraform-aws-eks examples
- Optimizing EKS cost or scaling to large clusters

**Don't use this skill for:**
- Generic Kubernetes concepts (Claude knows these)
- Provider-specific API reference (link to AWS docs)
- Non-EKS container orchestration (ECS, Lambda)
- Step-by-step EKS upgrade execution — this skill covers upgrade strategy and architectural decisions, not the per-version procedures themselves.

How to install

The exact contents, by fingerprint
mdr add aws-samples/sample-apex-skills/eks-best-practices@sha256:a73354dbb75bd760

The line at the top of this page pins the label git:20261108.ee86272, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
