Can I share one Load Balancer across multiple EKS services?

Yes, the skill includes patterns for using IngressGroups with the AWS Load Balancer Controller to consolidate multiple Ingress resources onto a single ALB.

Does this support security group management for individual pods?

Yes, it provides implementation steps for SecurityGroupPolicy (SGP), allowing you to assign AWS Security Groups directly to Kubernetes pods for fine-grained network control.

How do I fix IP exhaustion in my EKS cluster?

This skill provides configurations for enabling Prefix Delegation in the VPC CNI plugin, which allows you to assign significantly more IP addresses to nodes, or guidance on migrating to IPv6.

How does this skill handle external DNS records?

It includes a complete workflow for installing and configuring ExternalDNS with IAM Roles for Service Accounts (IRSA) to automatically sync Kubernetes services with Amazon Route 53.
