Metrics are collected as log events using embedded metric format, which When they first launch the EC2 worker nodes will use the CA certificate and EKS token provided to them to configure themselves and communicate with the EKS master node. Since there installed on all Kubernetes/EKS worker nodes will also produce log output. For Kubernetes cluster components that run in pods, these write to files inside the /var/log directory, bypassing the default logging mechanism. You can add node labels, taints, etc by using the --kubelet-extra-args option on the bootstrap. Since node groups instance types are immutable (as mentioned in this SO answer) Terraform is probably deleting the node group and recreating it, deleting all of the pods they At Autify, we historically have chosen AL2 as our default EKS worker node host OS simply because it was the only EKS Optimized AMI option for Linux workloads. The worker nodes in a Kubernetes cluster will generate system logs based on the operating system in use. Adding your worker node is achieved through EKS NodeGroup: it mostly consist of managed autoscaling groups of EC2 instances integrated within the In addition to master nodes, a K8s cluster is made up of worker nodes where containers are scheduled and run.
