Description=K3s Kubernetes agent (Mulga EKS GPU worker)
|
|
# K3S_URL points at the cluster's NLB endpoint (https://{cluster}.{account}
|
|
# .eks.{region}.{suffix}:443) so the agent join path stays stable across the
|
|
# v2 HA migration (single-VM v1 -> 3-node etcd quorum v2). No AMI rebuild
|
|
# needed when the control plane expands.

# ContainerManager.Start fails before Node registration (OpenRC ran k3s in the
|
|
# root cgroup, so this was implicit). overlay/br_netfilter feed the embedded
