Installation of NEVIS

Introduction

I decided to install NEVIS inside a kubernetes cluster.

Installation of kubernetes

~~Add the Kubernetes~~ yum ~~repository. If you want to use Kubernetes version different than v1.31, replace v1.31 with the desired minor version in the command below.~~

# This overwrites any existing configuration in /etc/yum.repos.d/kubernetes.repo
cat <<EOF | sudo tee /etc/yum.repos.d/kubernetes.repo
[kubernetes]
name=Kubernetes
baseurl=https://pkgs.k8s.io/core:/stable:/v1.31/rpm/
enabled=1
gpgcheck=1
gpgkey=https://pkgs.k8s.io/core:/stable:/v1.31/rpm/repodata/repomd.xml.key
EOF

Fedora installation of kubernetes

sudo dnf install kubernetes-kubeadm kubernetes-node kubernetes-client

Open firewall ports 6443, 10250

sudo systemctl enable kubelet.service
sudo systemctl enable containerd
sudo systemctl start containerd
sudo swapoff -a
sudo dnf install iptables iproute-tc

sudo cat <<EOF | sudo tee /etc/modules-load.d/k8s.conf
overlay
br_netfilter
EOF


sudo modprobe overlay
sudo modprobe br_netfilter

# sysctl params required by setup, params persist across reboots
sudo cat <<EOF | sudo tee /etc/sysctl.d/k8s.conf
net.bridge.bridge-nf-call-iptables  = 1
net.bridge.bridge-nf-call-ip6tables = 1
net.ipv4.ip_forward                 = 1
EOF


sudo sysctl --system

sudo systemctl enable --now kubelet

sudo kubeadm init
