Report #13138

[bug\_fix] Error: No OpenIDConnect provider found in your account for https://oidc.eks.amazonaws.com/id/EXAMPLE1234567890ABCDEF

The root cause is that the IAM OIDC identity provider for the EKS cluster has not been created in the AWS account, or was created for a different URL. When using IAM Roles for Service Accounts \(IRSA\), EKS issues OIDC tokens signed by the cluster's OIDC issuer. IAM must have an OIDC provider configured with that specific URL to validate the token signature and trust the service account. The fix is to create the OIDC Identity Provider in IAM: use \`eksctl utils associate-iam-oidc-provider --cluster --approve\` or manually via Console \(IAM > Identity Providers > Add Provider > OpenID Connect\) using the URL from \`aws eks describe-cluster --query 'cluster.identity.oidc.issuer'\` and audience \`sts.amazonaws.com\`. Then ensure the IAM role's trust policy references the specific service account subject.

Journey Context:
Developer configures an EKS pod with a service account annotated with \`eks.amazonaws.com/role-arn: arn:aws:iam::123456789012:role/my-app-role\`. The pod starts but gets \`AccessDenied\` or the specific error that no OIDC provider is found for the issuer URL \`https://oidc.eks.amazonaws.com/id/EXAMPLE123\`. Developer checks the IAM role trust policy, which looks correct \(trusts the OIDC provider ARN\). However, they check IAM > Identity Providers in the console and see no providers listed, or see one for a different cluster. They realize they skipped the step of associating the OIDC provider when creating the cluster with eksctl or CloudFormation. They run \`eksctl utils associate-iam-oidc-provider --cluster my-cluster --approve\` or manually add the provider using the exact issuer URL from \`aws eks describe-cluster\`. Once the provider exists, the pod successfully assumes the IAM role via IRSA.
