Can this skill help with CrashLoopBackOff errors?

Yes, it provides specific diagnostic commands to check container logs, exit codes, and previous states to identify and fix the root cause of application crashes.

Does it cover AWS-specific issues like IRSA?

Absolutely. It includes workflows to verify IAM roles for service accounts (IRSA), check pod annotations, and test AWS credential access from within the cluster.

Is this skill updated for recent EKS versions?

Yes, the guide is based on 2025 AWS best practices and utilizes modern Kubernetes features like ephemeral containers for debugging node and pod issues.

How does it handle EKS networking problems?

The skill provides guides for VPC CNI issues, including IP address exhaustion, prefix delegation configuration, and troubleshooting DNS resolution failures.
