After a phone call with @jwcesign, we decided to use aliyuncli to create RAM Sub-account, get its ak, sk, region profiles, and use secret to store them, which will be used by karpenter to create ecsclient.

The current implementation provides access based on the currently provided authentication information, and subsequent implementations can be tracked: #29

Test Step:

• aliyun configure set --profile AkProfile --mode AK --access-key-id xxx --access-key-secret xxx --region xxx
• add test code:

func TestNewECSClient(t *testing.T) {
    client, err := NewECSClient()
    if err != nil {
        t.Errorf("Failed to create ECS client: %v", err)
    }

    describeZonesRequest := &ecsclient.DescribeZonesRequest{
        RegionId: client.RegionId,
    }
    runtime := &util.RuntimeOptions{}

    if _, err := client.DescribeZonesWithOptions(describeZonesRequest, runtime); err != nil {
        t.Error(err)
    }
}
