fluent-bit's HTTP server (and the non-cluster-host
in_httpinput) default to listening on0.0.0.0. On an IPv6-only cluster the pod has no IPv4 address, so the kubelet's probes to[podIP]:2020never connect:calico-fluent-bitstays0/1,log-collectorstays Degraded, and the weeklyce-ipv6suite has never passed.http_listenand thein_httplistento${POD_IP}(downward APIstatus.podIP), for both the DaemonSet and the EKS log forwarder.::: works for v4, v6 and dual-stack, doesn't depend on IP pools (empty with non-Calico CNIs like AWS VPC CNI), and avoids::failing on nodes with IPv6 disabled or being v6-only on Windows.🤖 Generated with Claude Code
