AWS IAM Access Analyzer vs kube2iam: Side-by-Side Comparison (2026)

kube2iam

Teams running Kubernetes on AWS who need to eliminate long-lived IAM credentials in pods will find kube2iam's annotation-driven approach simpler than managing separate credential distribution systems. The tool intercepts metadata API calls at the container level, meaning you get temporary credentials without adding a sidecar or rewriting application code, and the 2,000+ GitHub stars reflect real adoption in production clusters. Skip this if you're standardizing on IRSA (IAM Roles for Service Accounts) or already using EKS; kube2iam is built for self-managed Kubernetes where metadata interception is still your cleanest option.
