AWS EKS Nodegroup Healthcheck

This codebundle queries the state of a nodegroup within a EKS cluster to check its state and raise issues if it's unhealthy.

Tasks

Check EKS Nodegroup Status

Configuration

The TaskSet requires initialization to import necessary secrets, services, and user variables. The following variables should be set:

  • aws_access_key_id: the service account's access key ID, used during the aws sts call.
  • aws_secret_access_key: The service account's secret access key, used during the aws sts call.
  • aws_role_arn: The full aws role ARN that will be assumed.
  • aws_assume_role_name: The name of the role to assume as part of the aws sts assume role call.
  • AWS_DEFAULT_REGION: The AWS region to perform API requests in and for resources.
  • AWS_SERVICE: The remote aws service to use for requests.
  • EKS_CLUSTER_NAME: The name of the EKS cluster to query.
  • EKS_NODEGROUP: The nodegroup within the cluster to check the status of.

Notes

This codebundle assumes a traditional service account authentication using the assume role functionality of aws sts, and therefore a role with the correct access will be required so that it can be assumed by the service account for a temporary token.

TODO

  • Add documentation
  • Look at dynamic/scaled nodegroup support
