Install Kubernetes on Fedora Server

Kubernetes is an open-source platform that automates container deployment, scaling, and management. In this tutorial, we will guide you on how to install Kubernetes on the latest Fedora Server.

Requirements

Before you begin with the installation process, ensure that your system meets the following requirements:

• Fedora Server latest
• Root privileges

Installation Steps

Follow the below steps one by one to install Kubernetes:

Step 1: Add Kubernetes Repository

To add Kubernetes repository on your system, run the following command:

$ sudo dnf install -y dnf-plugins-core
$ sudo dnf config-manager --add-repo=https://packages.cloud.google.com/yum/repos/kubernetes-el7-x86_64

Step 2: Install Docker and Kubernetes Packages

After adding the repository, install Docker and Kubernetes packages using the following command:

$ sudo dnf install -y kubelet kubeadm kubectl docker

Step 3: Enable Docker and Kubernetes Services

Enable the Docker and Kubernetes services using the below commands:

$ sudo systemctl enable docker
$ sudo systemctl enable kubelet

Step 4: Start the Services

To start the Docker and Kubernetes services, run the following command:

$ sudo systemctl start docker
$ sudo systemctl start kubelet

Step 5: Initialize Kubernetes Cluster

Run the following command to initialize the Kubernetes cluster:

$ sudo kubeadm init

The output of this command will give you the next steps to follow to configure your Kubernetes cluster. Make note of the generated token, as you will need it for other nodes to join the cluster.

Step 6: Configure Kubectl

After initializing the cluster, configure kubectl by running the following command:

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

Step 7: Apply Flannel Network

Flannel is a popular networking solution that can be applied to your cluster. To apply the Flannel network, run the following command:

$ sudo kubectl apply -f https://raw.githubusercontent.com/coreos/flannel/master/Documentation/kube-flannel.yml

Step 8: Join Other Nodes

To join other nodes to the Kubernetes cluster, run the following command on them after replacing 'token' and 'hash' with the generated values:

$ sudo kubeadm join <master-ip>:<master-port> --token token --discovery-token-ca-cert-hash hash

Conclusion

You have successfully installed Kubernetes on Fedora Server successfully. Now you can begin deploying containers and managing them using the kubectl command.
