Now that we have modified the IAM role for the worker nodes to permit write operations to the X-Ray service, we are going to deploy the X-Ray DaemonSet to the EKS cluster. The X-Ray daemon will be deployed to each worker node in the EKS cluster. For reference, see the example implementation used in this module.
The AWS X-Ray SDKs are used to instrument your microservices. When using the DaemonSet in the example implementation, you need to configure it to point to xray-service.default:2000.
The following showcases how to configure the X-Ray SDK for Go. This is merely an example and not a required step in the workshop.
func init() {
xray.Configure(xray.Config{
DaemonAddr: "xray-service.default:2000",
LogLevel: "info",
})
}
To deploy the X-Ray DaemonSet:
kubectl create -f https://eksworkshop.com/intermediate/245_x-ray/daemonset.files/xray-k8s-daemonset.yaml
To see the status of the X-Ray DaemonSet:
kubectl describe daemonset xray-daemon
The folllowing is an example of the command output:
To view the logs for all of the X-Ray daemon pods run the following
kubectl logs -l app=xray-daemon
