Also, install curl as it will be necessary for the next steps. You will start by installing the apt- transport- https package which enables working with http and https in Ubuntu’s repositories. Use ssh to login into both nodes and proceed. Just like you did with Docker in the prerequisites, you must run the commands in both nodes to install Kubernetes. In this step, we will be installing Kubernetes. You may follow steps 1, 2, and 3 of our tutorial on installing and operating Docker. Docker will provide the runtime environment needed by Ubuntu. While there are other container platforms to choose from, we will be using Docker in this tutorial. Kubernetes relies on a container runtime to run containers in pods. You will need to install and enable Docker on each of the nodes. If you are working from a local network, you may have to edit your /etc/hosts file in each server and link them appropriately. When you deploy your VMs from CloudSigma, they will be connected to the internet with a public IP by default. Network connectivity – the servers in the cluster should be able to communicate. Follow this tutorial on configuring the Linux sudoers file for instructions.
However, you are free to choose the hostnames you prefer.Įnsure you add a user with sudo privileges on both nodes that we will use to run the commands as outlined in the tutorial above. This makes it easier to follow along with the tutorial.
We have aptly named our two servers as kubernetes- master and kubernetes- worker. One server will be the master node, the other will be the worker node. You may follow steps 1 to 4 of this step-by-step tutorial to help you set up your Ubuntu server on CloudSigma. For best performance, the minimum system requirements for Kubernetes are 2GB of RAM and 2 CPUs. You will need to provision two servers, running on Ubuntu 20.04. It is also advisable to first get acquainted with our tutorial on getting to know Kubernetes tool-kit basics to familiarize yourself with the basics of the Kubernetes platform. You will learn more about some defining components of Kubernetes such as kubectl and kubeadm as we go along. This is a typical real-life application of Kubernetes. To test our configuration, we will deploy a Docker container running the Nginx webserver to the cluster.
We will further show you how to link the two servers to allow the master node to control the worker node. You also have the option to add more worker nodes once you understand the fundamentals. As mentioned, having two nodes is the most basic configuration when working with Kubernetes.
Copy the adb zip contents of adb.exe, fastboot.exe, AdbWinApi.
This guide will walk you through the steps of installing and deploying a Kubernetes cluster consisting of two nodes on Ubuntu 20.04. Method 1: Method 1 allows you to run adb tools from any directory by adding it to the Windows path variables. Worker nodes are servers that run the workloads – these are typically containerized applications and services. A master node is a server that manages the state of the cluster. Keeping scalability in mind, you have the option to expand the cluster with as many worker nodes as required.Ī node in Kubernetes refers to a server. A cluster needs a minimum of two nodes to work – one master node and a worker node. A cluster is a set of hosts meant for running containerized applications and services. Kubernetes works by orchestrating and managing clusters at scale across various cloud environments or even on-premise servers. On the first page of the installer, select English and click Continue button.Kubernetes is an open-source tool that is crucial in container orchestration.
