K9s is a versatile command-line tool that simplifies the management of Kubernetes clusters. There are two options for installing K9s, namely via snap and manual installation from the source files provided on GitHub. In this tutorial, we will discuss how to install manually. To install K9s on Ubuntu Linux system manually, we will follow these steps:
Step 1. Update System Repository
Step 2. Install Kubectl
Step 3. Installing K9s on Ubuntu 22.04
Update System Repository
Before installing any new software, it’s a good practice to update the system packages. Open a terminal and run the following command :
$ sudo apt update
2. Install Kubectl
Kubectl installation has been discussion on previous tutorial.
We will verify it by querying its version.
$ kubectl version --output=yaml
Output :
ramansah@infodiginet:~$ kubectl version --output=yaml clientVersion: buildDate: "2023-08-24T11:23:10Z" compiler: gc gitCommit: 8dc49c4b984b897d423aab4971090e1879eb4f23 gitTreeState: clean gitVersion: v1.28.1 goVersion: go1.20.7 major: "1" minor: "28" platform: linux/amd64 kustomizeVersion: v5.0.4-0.20230601165947-6ce0bf390ce3
3. Install K9S on Ubuntu 22.04
To install K9S, we will use the source file from K9S official source. We need to download K9S source file by using curl command line :
$ curl -LO https://github.com/derailed/k9s/releases/download/v0.27.4/k9s_Linux_amd64.tar.gz
Output :
ramansah@infodiginet:~$ curl -LO https://github.com/derailed/k9s/releases/download/v0.27.4/k9s_Linux_amd64.tar.gz % Total % Received % Xferd Average Speed Time Time Time Current Dload Upload Total Spent Left Speed 0 0 0 0 0 0 0 0 --:--:-- 0:00:06 --:--:-- 0 100 17.7M 100 17.7M 0 0 79572 0 0:03:54 0:03:54 --:--:-- 196k
Then we extract it by using tar command line :
$ tar xf k9s_Linux_amd64.tar.gz $ sudo mv k9s /usr/local/bin
After extracting was completed done, then we will verify it by submitting command line :
$ k9s version
Output :
ramansah@infodiginet:~$ k9s version ____ __.________ | |/ _/ __ \______ | < \____ / ___/ | | \ / /\___ \ |____|__ \ /____//____ > \/ \/ Version: v0.27.4 Commit: f4543e9bd2f9e2db922d12ba23363f6f7db38f9c Date: 2023-05-07T16:55:34Z
To use K9S, we just submit the following command line :
$ k9s
The output will be as shown below :
