Simplify Kubernetes cluster management using ACK, kro and Amazon EKS
Containers Blog
This article demonstrates how to simplify Kubernetes cluster management using kro, AWS Controllers for Kubernetes (ACK), and Argo CD for GitOps-based provisioning.
- kro orchestrates ACK resources and manages dependencies between AWS resources automatically
- ResourceGraphDefinitions (RGDs) encapsulate all resources needed for fully functioning EKS clusters
- Common Expression Language (CEL) extracts generated fields and passes them to dependent resources
- IAM Role Selectors enable cross-account resource creation in multi-account AWS environments
- Argo CD ApplicationSets deploy add-ons across multiple workload clusters automatically
- EKS access entries and Pod Identity grant proper IAM permissions to add-ons
- Solution eliminates need for separate IaC pipelines by using Kubernetes API end-to-end
This approach standardizes cluster provisioning through a single Kubernetes API, reducing operational complexity and improving consistency across multi-cluster environments.
