External mode on-premises

Available since

version 1.7

In external mode, the ingress controller runs outside of your Kubernetes cluster. In this guide, you will learn how to set up external mode using an on-premises cluster and Project Calico.

In this scenario, we deploy a custom Kubernetes installation that uses Project Calico as its Container Networking Interface (CNI) plugin. A CNI plugin is responsible for defining the virtual network that pods use to communicate with one another. Because a pod network is typically accessible only to Kubernetes pods, we need a way to bridge this network with a public-facing, external network.

Project Calico has the ability to perform BGP peering between the pod network and an external network, allowing us to install and run the ingress controller external to Kubernetes, while still receiving IP route advertisements that enable it to relay traffic to pods.

We will use the following components:

Component	Description
HAProxy Kubernetes Ingress Controller	The ingress controller runs as a standalone process outside of your Kubernetes cluster.
Project Calico	Project Calico is a network plugin for Kubernetes. It supports BGP peering, which allows pods inside your Kubernetes cluster to share their IP addresses with a server outside of the cluster.
BIRD Internet Routing Daemon	BIRD is a software-defined router. It receives routes from Project Calico and makes them available to the ingress controller.

Prepare servers for Kubernetes Jump to heading

Deploy Linux servers that will host your Kubernetes components.

You will need:

a control plane server: one Linux server to run the Kubernetes control plane and be responsible for managing the cluster and hosting the Kubernetes API.
worker nodes: one or more Linux servers to act as Kubernetes worker nodes, which host pods.
ingress controller server: one Linux server to run HAProxy Kubernetes Ingress Controller.

On the control plane server and worker nodes, perform these steps:

Follow the Install Docker Engine guide to install Docker and Containerd on the server. Containerd will serve as the container runtime in Kubernetes.
By default, the Containerd configuration file, /etc/containerd/config.toml, disables the Container Runtime Interface (CRI) plugin that Kubernetes needs. We also need to enable Systemd cgroups because kubeadm installs the Kubernetes service, kubelet, as a Systemd service. The easiest method is to generate a default configuration file and then make changes to it using sed, the search-and-replace tool.
```
nix
containerd config default | sudo tee /etc/containerd/config.toml
sudo sed -i 's/SystemdCgroup = false/SystemdCgroup = true/' /etc/containerd/config.toml
sudo systemctl restart containerd
```
```
nix
containerd config default | sudo tee /etc/containerd/config.toml
sudo sed -i 's/SystemdCgroup = false/SystemdCgroup = true/' /etc/containerd/config.toml
sudo systemctl restart containerd
```
Disable swap, as required by the Kubernetes kubelet service.
```
nix
swapoff -a
```
```
nix
swapoff -a
```
Follow the Installing kubeadm guide to install the kubeadm, kubectl, and kubelet packages. We will use the kubeadm tool to install Kubernetes.

Configure the Kubernetes control plane server Jump to heading

At least one server must become the central management server, otherwise known as the control plane. On that server, perform the following additional steps:

Call kubeadm init to install Kubernetes on this server. Replace the value of --apiserver-advertise-address with your server’s IP address. Set --pod-network-cidr to the IP range you want to use for your Kubernetes cluster’s private network. Be sure that this range does not overlap with other IP ranges already in use on your network.

nix
sudo kubeadm init \
  --cri-socket unix:///run/containerd/containerd.sock \
  --pod-network-cidr 172.16.0.0/16 \
  --apiserver-advertise-address 192.168.56.10

nix
sudo kubeadm init \
  --cri-socket unix:///run/containerd/containerd.sock \
  --pod-network-cidr 172.16.0.0/16 \
  --apiserver-advertise-address 192.168.56.10

Argument	Description
`--cri-socket`	Sets the path to the Containerd CRI socket.
`--pod-network-cidr`	Sets the range of IP addresses to use for the pod network. Each new pod will receive an IP address in this range. The IP range `172.16.0.0/16` allows up to 65534 unique IP addresses.
`--apiserver-advertise-address`	Add this optional argument if your server has more than one IP address assigned to it to specify the address on which the Kubernetes API should listen.

Refer to the kubeadm init documentation guide for more information about these and other arguments.

After the installation, a kubeconfig file is created at /etc/kubernetes/admin.conf. This contains settings for connecting to the new Kubernetes cluster. Copy it to your home directory and to the root user’s home directory. This allows you to connect to the Kubernetes API using kubectl and we will configure Project Calico, which will connect as root, to use this kubeconfig file too.

nix
sudo mkdir $HOME/.kube
sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
sudo chown $(id -u):$(id -g) $HOME/.kube/config
sudo mkdir /root/.kube
sudo cp -i /etc/kubernetes/admin.conf /root/.kube/config
sudo chown root:root /root/.kube/config

nix
sudo mkdir $HOME/.kube
sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
sudo chown $(id -u):$(id -g) $HOME/.kube/config
sudo mkdir /root/.kube
sudo cp -i /etc/kubernetes/admin.conf /root/.kube/config
sudo chown root:root /root/.kube/config

Optional: If the server has more than one IP address assigned to it, you must configure the Kubernetes kubelet service to use the correct one. In the file /etc/default/kubelet (or /etc/sysconfig/kubelet), set the --node-ip argument to your server’s IP address. It’s also a good idea to set the path to the Containerd socket explicitly via the --container-runtime-endpoint argument. Then restart the service.

nix
sudo touch /etc/default/kubelet
echo "KUBELET_EXTRA_ARGS=--node-ip=192.168.56.10 --container-runtime-endpoint=unix:///run/containerd/containerd.sock" | sudo tee /etc/default/kubelet
sudo systemctl daemon-reload
sudo systemctl restart kubelet

nix
sudo touch /etc/default/kubelet
echo "KUBELET_EXTRA_ARGS=--node-ip=192.168.56.10 --container-runtime-endpoint=unix:///run/containerd/containerd.sock" | sudo tee /etc/default/kubelet
sudo systemctl daemon-reload
sudo systemctl restart kubelet

At this point, the Kubernetes control plane should be running. You can use the kubectl get pods command to check that the pods are running sucessfully. It is normal for the coredns pods to be in the Pending state at this time.

nix
kubectl get pods -A

nix
kubectl get pods -A

Install the Project Calico Container Network Interface (CNI) plugin. We’ll use the Project Calico plugin because it supports BGP peering, which we’ll need for connecting the ingress controller to the Kubernetes cluster’s private network.

Refer to the Project Calico Quickstart guide for instructions on installing the operator and custom resource definitions. Note that by default Project Calico expects a pod network CIDR of 192.168.0.0/16. Since, we are using 172.16.0.0/16 instead, edit the custom-resources.yaml file before installing it.

In the example below, we change the spec.calicoNetwork.ipPools.cidr field to 172.16.0.0/16:

custom-resources.yaml
yaml
# This section includes base Calico installation configuration.

Then create the resources:

nix
kubectl create -f ./custom-resources.yaml

nix
kubectl create -f ./custom-resources.yaml

Download the calicoctl command-line tool.

Copy it to the /usr/local/bin directory and set its permissions to make it executable:

nix
sudo cp ./calicoctl /usr/local/bin
sudo chmod +x /usr/local/bin/calicoctl

nix
sudo cp ./calicoctl /usr/local/bin
sudo chmod +x /usr/local/bin/calicoctl

Create a file named /etc/calico/calicoctl.cfg.

nix
sudo mkdir /etc/calico
sudo touch /etc/calico/calicoctl.cfg

nix
sudo mkdir /etc/calico
sudo touch /etc/calico/calicoctl.cfg

Add the following contents to it, which configures calicoctl to connect to your Kubernetes cluster using the kubeconfig file from the root user’s home directory.

calicoctl.cfg
yaml
apiVersion: projectcalico.org/v3
kind: CalicoAPIConfig
metadata:

Create a file named /etc/calico/calico-bgp.yaml.

nix
sudo touch /etc/calico/calico-bgp.yaml

nix
sudo touch /etc/calico/calico-bgp.yaml

Add the following to it to enable BGP peering with your external network. Change the peerIp field to be the IP address of the server where you will run the ingress controller.

Argument	Description
`asNumber`	Defines the BGP autonomous system (AS) number you wish to use.
`peerIP`	Defines the IP address of the server where you will install the ingress controller.

Apply it with the calicoctl apply command:

nix
sudo calicoctl apply -f /etc/calico/calico-bgp.yaml

nix
sudo calicoctl apply -f /etc/calico/calico-bgp.yaml

Create an empty ConfigMap resource in your cluster, which the ingress controller requires upon startup.

nix
sudo kubectl create configmap haproxy-kubernetes-ingress

nix
sudo kubectl create configmap haproxy-kubernetes-ingress

To verify the setup, call calicoctl node status. The Info column should show Connection refused. This is expected because we have not configured the ingress controller yet to serve as the neighbor BGP peer.

nix
sudo calicoctl node status

nix
sudo calicoctl node status

Configure the Kubernetes worker nodes Jump to heading

Kubernetes worker nodes host pods. On each server that you wish to register as a worker node in the Kubernetes cluster, after following the steps in the Prepare servers for Kubernetes, perform these additional steps:

On the control plane server, call kubeadm token create --print-join-command, which shows the kubeadm join command you need to join a server to the cluster.

For example:

nix
kubeadm token create --print-join-command

nix
kubeadm token create --print-join-command

Copy its output and run it on the worker node server:

nix
sudo kubeadm join 192.168.56.10:6443 \
  --token jqfhgn.bgvy9xko70q82awu \
  --discovery-token-ca-cert-hash sha256:ce4dfb0efa64a0bb9071268c7a94258a9fef56be89e909a21f16f2528d8c880b

nix
sudo kubeadm join 192.168.56.10:6443 \

Install the ingress controller outside of your cluster Jump to heading

On a separate server not joined to your Kubernetes cluster, follow these steps to install the HAProxy Kubernetes Ingress Controller as a standalone process.

Copy the /etc/kubernetes/admin.conf kubeconfig file from the control plane server to this server and store it in the root user’s home directory. The ingress controller will use this to connect to the Kubernetes API.
```
nix
sudo mkdir -p /root/.kube
sudo cp admin.conf /root/.kube/config
sudo chown -R root:root /root/.kube
```
```
nix
sudo mkdir -p /root/.kube
sudo cp admin.conf /root/.kube/config
sudo chown -R root:root /root/.kube
```
HAProxy Kubernetes Ingress Controller is compatible with a specific version of HAProxy. Install the HAProxy package on your Linux distribution based on the table below. For Ubuntu and Debian, follow the install steps at haproxy.debian.net.

Ingress controller version Compatible HAProxy version

1.11 2.8

1.10 2.7

1.9 2.6

1.8 2.5

1.7 2.4

Ingress controller version	Compatible HAProxy version
1.11	2.8
1.10	2.7
1.9	2.6
1.8	2.5
1.7	2.4

Stop and disable the HAProxy service.

nix
sudo systemctl stop haproxy
sudo systemctl disable haproxy

nix
sudo systemctl stop haproxy
sudo systemctl disable haproxy

Call the setcap command to allow HAProxy to bind to ports 80 and 443:

nix
sudo setcap cap_net_bind_service=+ep /usr/sbin/haproxy

nix
sudo setcap cap_net_bind_service=+ep /usr/sbin/haproxy

Download the ingress controller from the project’s GitHub Releases page.

Extract it and then copy it to the /usr/local/bin directory.

Install the BIRD Internet Routing Daemon Jump to heading

To enable the ingress controller to route requests to pods in your Kubernetes cluster, it must get routing information via BGP from the Project Calico network plugin. To do that, install the BIRD Internet Routing Daemon, which acts as a software-defined router that adds IP routes to the ingress controller server.

Supported BIRD versions

Only BIRD 1.x is supported at this time.

On the ingress controller server, install BIRD.

nix
sudo add-apt-repository -y ppa:cz.nic-labs/bird
sudo apt update
sudo apt install bird

nix
sudo add-apt-repository -y ppa:cz.nic-labs/bird
sudo apt update
sudo apt install bird

Edit the file named bird.conf in the /etc/bird directory. Add the following contents to it, but change:

the router id to the current server’s IP address. This is the IP address of the ingress controller server.
the local line’s IP address in each protocol section to the current server’s IP address. Again, this the IP address of the ingress controller server.
the neighbor line to the IP address of a node in your Kubernetes cluster. One of these should be the control plane server’s IP address.
the import filter should match the pod network’s IP range that you set earlier with kubeadm init.

bird.conf
javascript
router id 192.168.56.13;
log syslog all;
# control plane node
protocol bgp {
   local 192.168.56.13 as 65000;
   neighbor 192.168.56.10 as 65000;
   direct;
   import filter {
      if ( net ~ [ 172.16.0.0/16{26,26} ] ) then accept;
   };
  export none;
}
# worker node
protocol bgp {
   local 192.168.56.13 as 65000;
   neighbor 192.168.56.11 as 65000;
   direct;
   import filter {
      if ( net ~ [ 172.16.0.0/16{26,26} ] ) then accept;
   };
   export none;
}
# Inserts routes into the kernel routing table
protocol kernel {
   scan time 60;
   export all;
}
# Gets information about network interfaces from the kernel
protocol device {
   scan time 60;
}

bird.conf
javascript
router id 192.168.56.13;
log syslog all;
# control plane node
protocol bgp {
   local 192.168.56.13 as 65000;
   neighbor 192.168.56.10 as 65000;
   direct;
   import filter {
      if ( net ~ [ 172.16.0.0/16{26,26} ] ) then accept;
   };
  export none;
}
# worker node
protocol bgp {
   local 192.168.56.13 as 65000;
   neighbor 192.168.56.11 as 65000;
   direct;
   import filter {
      if ( net ~ [ 172.16.0.0/16{26,26} ] ) then accept;
   };
   export none;
}
# Inserts routes into the kernel routing table
protocol kernel {
   scan time 60;
   export all;
}
# Gets information about network interfaces from the kernel
protocol device {
   scan time 60;
}

Each protocol bgp section connects BIRD to a Kubernetes node via iBGP. Each is considered a neighbor. This example uses 65000 as the Autonomous System number, but you can choose a different value.

Enable and start the BIRD service.

nix
sudo systemctl enable bird
sudo systemctl restart bird

nix
sudo systemctl enable bird
sudo systemctl restart bird

After completing these steps, the ingress controller is configured to communicate with your Kubernetes cluster and, once you’ve added an Ingress resource using kubectl, it can route traffic to pods. Learn about creating Ingress resources for routing traffic in the section Use HAProxy Kubernetes Ingress Controller to route HTTP traffic.

Be sure to allow the servers to communicate by adding rules to your firewall.

On the ingress controller server, calling sudo birdc show protocols should show that connections have been established with the control plane server and any worker nodes.
