CapsuleCD is a tool that allows you to create bootable CDs and USB drives for use with Kubernetes. In this tutorial, we will guide you through the process of installing CapsuleCD on your macOS machine.
Before we begin, you will need the following:
CapsuleCD is written in Ruby, so we need to ensure that Ruby is installed on our machine. To do this, we will use Homebrew to install Ruby:
brew install ruby
After the installation, verify that Ruby is installed by running ruby -v.
Now that we have Ruby installed, we can install CapsuleCD. We will use RubyGems, which is a package manager for Ruby:
sudo gem install capsulecd
After the installation, verify that CapsuleCD is installed by running capsulecd version.
Let's create our first CapsuleCD project by running:
capsulecd init myproject
This will create a new CapsuleCD project named myproject.
To create a bootable CD or USB drive, we need to add dependencies to our project. For this tutorial, let's add the following dependencies to our myproject project:
Add the dependencies by editing the Gemfile in the root directory of your myproject project:
source 'https://rubygems.org'
gem 'kubernetes', '~> 1.20.0'
gem 'prometheus', '~> 2.30.0'
After adding the dependencies, run bundle install to install them.
To build the Capsule, run the following command:
capsulecd build myproject
This will create a Capsule in the myproject/capsule directory.
You can now use the Capsule to create bootable CDs and USB drives for Kubernetes.
Congratulations, you have successfully installed CapsuleCD on your macOS machine!
In this tutorial, you learned how to install CapsuleCD on macOS, create a Capsule project, add dependencies, and build the Capsule. CapsuleCD is a powerful tool that simplifies the process of creating bootable CDs and USB drives for Kubernetes, and we hope that this tutorial has helped you get started with it.
If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!
Alternatively, for the best virtual desktop, try Shells!
