Introduction
Deploying applications to Kubernetes is a complicated process. Many tools simplify this process, and one of them is Helm.
Helm is a package manager for Kubernetes that configures and deploys applications and services on a Kubernetes cluster. It uses Helm charts to simplify the development and deployment process.
In this step-by-step tutorial, you will learn how to install Helm on Ubuntu, Mac, or Windows.
Prerequisites
- A system running Ubuntu, Windows, or Mac
- Access to a command line/terminal
- A Kubernetes cluster installed and configured
How to Install Helm
Helm supports installations on Ubuntu, Mac, and Windows. Before installing Helm on any operating system, it is necessary to set up a Kubernetes cluster.
Note: See How to Install Kubernetes on Ubuntu or How to Install Kubernetes on CentOS if you do not have the Kubernetes cluster installed.
Installing Helm on Ubuntu
To install Helm on Ubuntu:
1. Download the latest version of Helm using the following command:
wget https://get.helm.sh/helm-v3.4.1-linux-amd64.tar.gz
The terminal prints out a confirmation message when the download completes.
2. Next, unpack the Helm file using the Linux tar command:
tar xvf helm-v3.4.1-linux-amd64.tar.gz
The output displays four unpacked files.
3. Move the linux-amd64/helm
file to the /usr/local/bin
directory:
sudo mv linux-amd64/helm /usr/local/bin
There will be no output if the command was executed correctly.
4. Remove the downloaded file using the command:
rm helm-v3.4.1-linux-amd64.tar.gz
5. Remove the linux-amd64
directory to clean up space by running:
rm -rf linux-amd64
There is no output if the process completes successfully.
6. Finally, verify you have successfully installed Helm by checking the version of the software:
helm version
The terminal prints out the version number of the software, as well as the release numbers of GitCommit, GitTreeState, and GoVersion.
Note: Upgrading your Helm releases can sometimes produce the “helm has no deployed releases” error.
Installing Helm on Mac
To install Helm on Mac:
1. Open the terminal app and install Homebrew (package manager for Mac) by entering the following command:
ruby -e "$(curl -fsSL
https://raw.githubusercontent.com/Homebrew/install/master/install)"
2. Follow the instructions in the terminal to complete the installation.
3. Next, verify the completion of the installation process by checking the Homebrew version:
brew –version
4. Install Helm using the following command:
brew install kubernetes-helm
5. Install Helm server on Kubernetes cluster by running:
helm init
The terminal prints out the “Happy Helming!” confirmation message when the installation process completes.
Installing Helm on Windows
To download Helm on Windows:
1. Follow the link below to download the latest Helm version.
https://github.com/helm/helm/releases
2. Locate the Windows amd64 download link from the Installation platform list and click on it to download.
3. Next, extract the windows-amd64 zip to the preferred location.
4. Open the command line window and enter the helm
command to verify that you have access to Helm.
5. Next, initialize Helm by entering the following command:
helm init
The output displays the “Happy Helming!” confirmation message when the initialization process is complete.
Note: In order to effectively deploy applications, you need to familiarize yourself with repositories management. Learn more by referring to our article How To Add, Update Or Remove Helm Repositories or download our Helm Cheat Sheet of basic Helm commands for further reference.
Conclusion
After following this step-by-step tutorial, you should have successfully installed Helm on Ubuntu, Mac, or Windows.
