Alternatively you can use an IAM role for authentication instead of an access key and secret, for Amazon EKS only:

auth:
  iamrole: arn:aws:iam::123456789012:role/foo

To setup an IAM role for service accounts, please refer to the official AWS documentation.

  • Schema of the data attribute: com.amazon.cloudwatch.metrics.message.json
• type com.amazon.cloudwatch.metrics.metric
  • Schema of the data attribute: com.amazon.cloudwatch.metrics.metric.json
