AWS - EKS
You configured an EKS cluster but your pods cannot access AWS services using IAM roles. What is a common cause?
AUsing kubectl instead of AWS CLI
BCluster is in ACTIVE state
CIAM roles for service accounts (IRSA) not enabled or configured
DPods are running on managed node groups
Step-by-Step Solution
Solution:
  1. Step 1: Identify cause of IAM access failure

    Pods need IAM roles via IRSA to access AWS services securely.
  2. Step 2: Check IRSA configuration

    If IRSA is not enabled or configured, pods cannot assume IAM roles.
  3. Final Answer:

    IAM roles for service accounts (IRSA) not enabled or configured -> Option C
  4. Quick Check:

    Pod AWS access issue = Check IRSA setup [OK]
Quick Trick: Enable IRSA for pod AWS permissions [OK]
Common Mistakes:
  • Assuming cluster ACTIVE state guarantees IAM access
  • Confusing node group type with IAM roles
  • Thinking kubectl affects IAM permissions
