Dalton Hubble e9c8520359 Add experimental Cilium CNI provider ... * Accept experimental CNI `networking` mode "cilium" * Run Cilium v1.8.0-rc4 with overlay vxlan tunnels and a minimal set of features. We're interested in: * IPAM: Divide pod_cidr into /24 subnets per node * CNI networking pod-to-pod, pod-to-external * BPF masquerade * NetworkPolicy as defined by Kubernetes (no L7 Policy) * Continue using kube-proxy with Cilium probe mode * Firewall changes: * Require UDP 8472 for vxlan (Linux kernel default) between nodes * Optional ICMP echo(8) between nodes for host reachability (health) * Optional TCP 4240 between nodes for endpoint reachability (health) Known Issues: * Containers with `hostPort` don't listen on all host addresses, these workloads must use `hostNetwork` for now https://github.com/cilium/cilium/issues/12116 * Erroneous warning on Fedora CoreOS https://github.com/cilium/cilium/issues/10256 Note: This is experimental. It is not listed in docs and may be changed or removed without a deprecation notice Related: * https://github.com/poseidon/terraform-render-bootstrap/pull/192 * https://github.com/cilium/cilium/issues/12217		2020-06-21 20:41:53 -07:00
