Kubernetes is a widely used container orchestration tool that helps automate container deployment, scaling, and management. It provides an efficient way to manage containerized applications in a clustered environment.
In this article, we will guide you through the process of installing Kubernetes on the terminal.
- A Linux-based operating system
- Docker installed and running
- A user with sudo privileges
Let's begin with the installation process.
Step 1: Install kubectl
The first step is to install the kubectl command-line tool, which is used to deploy and manage applications on Kubernetes. You can install it using the following command:
sudo apt-get update && sudo apt-get install -y kubectl
Step 2: Install Minikube
Minikube is a tool that enables you to run a single-node Kubernetes cluster on your local machine. You can install it using the following command:
curl -LO https://storage.googleapis.com/minikube/releases/latest/minikube-linux-amd64
sudo install minikube-linux-amd64 /usr/local/bin/minikube
Step 3: Start Minikube
After installing Minikube, start it using the following command:
This command will start a single-node Kubernetes cluster on your local machine.
Step 4: Verify the installation
To verify that Kubernetes is installed and running, run the following command:
This command will display the version of both the kubectl command-line tool and the Kubernetes server.
Step 5: Deploy an application
Now that you have Kubernetes up and running, you can deploy your first application. For example, you can deploy the Kubernetes dashboard using the following command:
kubectl apply -f https://raw.githubusercontent.com/kubernetes/dashboard/v2.0.0-beta8/aio/deploy/recommended.yaml
This command will deploy the Kubernetes dashboard on your local machine.
Step 6: Access the Kubernetes dashboard
To access the Kubernetes dashboard, run the following command:
This command will open the Kubernetes dashboard in your default web browser.
Congratulations! You have successfully installed and configured Kubernetes on your local machine.
