AWS EKS metric beat missing cluster information

[Steve_Foster]

We have a number of EKS clusters and can see that we are missing some metadata related to the cluster is missing in metrics

The items that we are missing are

• orchestrator.cluster.id
• orchestrator.cluster.name

these are defined at https://github.com/elastic/beats/blob/main/libbeat/processors/add_cloud_metadata/provider_aws_ec2.go#L119-L120

Replicating the AWS API call in https://github.com/elastic/beats/blob/main/libbeat/processors/add_cloud_metadata/provider_aws_ec2.go#L126-L141 via the cli

[root@ip-10-1-3-14 /]# AWS_PAGER="" aws ec2 describe-tags --filters Name=resource-id,Values=i-1234567890 Name=key,Values=eks:cluster-name
{
    "Tags": []
}

the cluster name is missing... but looking at all the tags I can see that AWS have started prefixing them with aws:

So updating the filter to match this change

[root@ip-10-1-3-14 /]# AWS_PAGER="" aws ec2 describe-tags --filters Name=resource-id,Values=i-123456789 Name=key,Values=aws:eks:cluster-name
{
    "Tags": [
        {
            "Key": "aws:eks:cluster-name",
            "ResourceId": "i-123456789",
            "ResourceType": "instance",
            "Value": "main"
        }
    ]
}
