Control plane node eno2 and worker node eno2 are in the same untagged VLAN.

Issue description
After applying calico-vpp-nohuge.yaml with additionally configured

  vpp_dataplane_interface: eno2

calico-kube-controllers loops in a CrashLoopBackOff with the following error in logs:

$ kubectl -n kube-system logs calico-kube-controllers-58497c65d5-xm54w

To Reproduce
Steps to reproduce the behavior:

Setup 2 n2.xlarge.x86 servers with Ubuntu 20.04 LTS on https://metal.equinix.com/.
- or just probably setup 2 bare-metal servers with Ubuntu 20.04 LTS.
Configure both of them to have:
1. Public IPv4 address on one interface (here it is bond0 with 147.75.38.85/31 for control plane node, with 147.75.75.133/31 for worker node).
2. Local IPv4 addresses in the same subnet on another interface (here it is eno2 with 10.0.0.1/30 for control plane node, with 10.0.0.2/30 for worker node).
  - on equinix metal this can be done with single VLAN assigned to the corresponding interfaces.
Configure docker on both nodes:

#!/bin/bash

mkdir -p /etc/docker

echo \
'{
    "exec-opts": ["native.cgroupdriver=systemd"]
}' >/etc/docker/daemon.json

Install environment on both nodes:

#!/bin/sh

KUBERNETES_VERSION=1.21.1-00

curl -s https://packages.cloud.google.com/apt/doc/apt-key.gpg | apt-key add -
cat <<EOF >/etc/apt/sources.list.d/kubernetes.list
deb https://apt.kubernetes.io/ kubernetes-xenial main
EOF

apt-get update
apt-get install -y docker.io
apt-get install -qy kubelet="${KUBERNETES_VERSION}" kubectl="${KUBERNETES_VERSION}" kubeadm="${KUBERNETES_VERSION}"

systemctl daemon-reload
systemctl restart kubelet

swapoff --all

Start kubernetes cluster on control plane node:

#!/bin/sh

set -e

K8S_DIR=$(dirname "$0")

KUBERNETES_INIT_VERSION=1.21.1
kubeadm init \
        --kubernetes-version "${KUBERNETES_INIT_VERSION}" \
        --pod-network-cidr=192.168.0.0/16 \
        --skip-token-print \
        --apiserver-advertise-address=147.75.38.85 # use here your control plane node public IP address

mkdir -p "$HOME"/.kube
sudo cp -f /etc/kubernetes/admin.conf "$HOME"/.kube/config
sudo chown "$(id -u):$(id -g)" "$HOME"/.kube/config

kubectl taint nodes --all node-role.kubernetes.io/master-

kubeadm token create --print-join-command > "${K8S_DIR}/join-cluster.sh"

Copy join-cluster.sh script from control plane node to worker node and run it.
Setup control plane node to use 10.0.0.1 as node IP:

#!/bin/sh

sed -Ei 's/(.*)"/\1 --node-ip=10\.0\.0\.1"/g' /var/lib/kubelet/kubeadm-flags.env
systemctl restart kubelet

Setup worker node to use 10.0.0.2 as node IP:

#!/bin/sh

sed -Ei 's/(.*)"/\1 --node-ip=10\.0\.0\.2"/g' /var/lib/kubelet/kubeadm-flags.env
systemctl restart kubelet

Copy ~/.kube/config from the control plane node to your own host.
Edit calico-vpp-nohuge.yaml with:

  vpp_dataplane_interface: eno2 # use here interface name used with local IPv4 address on nodes

Run kubectl apply -f calico-vpp-nohuge.yaml from your own host.

Expected behavior
All calico pods should start running (probably with few restarts).

Additional context

Same setup with weave as CNI works correctly.
Control plane node is able to reach 10.96.0.1:443:

$ nc -vw 2 10.96.0.1 443
Connection to 10.96.0.1 443 port [tcp/https] succeeded!

Worker node is able to reach 10.96.0.1:443:

$ nc -vw 2 10.96.0.1 443
Connection to 10.96.0.1 443 port [tcp/https] succeeded!

None of pods with hostNetwork: false from kube-system is able to reach 10.96.0.1:443:

$ kubectl -n kube-system exec alpine -- nc -vw 2 10.96.0.1 443
nc: 10.96.0.1 (10.96.0.1:443): Operation timed out
command terminated with exit code 1

I am not sure if it should be located here or under projectcalico/calico, so please correct me if I am wrong.

Hi @Bolodya1997 , you're in the right place 🙂

Thanks for the detailed report, this is very helpful! I noticed you used a public IP for the apiserver (--apiserver-advertise-address=147.75.38.85 in kubeadm init). Could you try with the IP address configured on eno2 on the master (10.0.0.1)?

If that doesn't fix the issue, it would be helpful if you could install calivppctl and attach the output of calivppctl export: https://docs.projectcalico.org/maintenance/troubleshoot/vpp

Bolodya1997 · 2021-09-01T03:55:20Z

Thank you!
I was afraid that k8s API server is listening only on the IP address given in --apiserver-advertise-address=, but it actually listens on all IP addresses.
So after changing this property to 10.0.0.1 it becomes only a question how to make TLS certificates work for the public IP, but it can be easy solved with this - https://blog.scottlowe.org/2019/07/30/adding-a-name-to-kubernetes-api-server-certificate/.
