Troubleshooting

Describe common failures and causes of the Cluster Optimizer.

Failed to obtain AWS credentials, the log shows getting credentials: exec: executable aws failed with exit code 253.

Main Cause: This error occurs when the aws command is used to obtain credentials for accessing EKS Kubernetes on AWS. By default, the aws CLI is not installed in Cluster Optimizer. Credentials are retrieved through the API, which requires automatic refresh of the kubeconfig. To resolve this issue, edit the cluster settings and select the option to Automatically refresh Kubeconfig.
