What You’ll Learn
In this lesson, we’re covering Multipass. A tool to run and launch Ubuntu VMs in seconds.
Why It’s Useful
Developed by the publishers of Ubuntu, Multipass is a light and fast way to spin up a Linux VM.
Unlike other all-in-one distributions like minikube, Multipass allows us to install a completely self-contained Kubernetes cluster locally. This is useful when working with multiple Kubernetes clusters to prevent overriding your existing Kubernetes configurations.
BARE METAL HYPERVISOR
In addition, Multipass uses a bare metal hypervisor that allows you to run directly on your computer’s hardware rather than being managed by your OS. The only way to gain faster performance is to install Kubernetes directly on a Linux kernel.
Install Multipass
Let’s start by installing Multipass.
Helpful Commands
Next, let’s get familiar with some of the commands. These are the most useful for working with Entando including stopping, starting, and shelling into the VM where we’ve installed the Kubernetes cluster.
Launch VM
multipass launch --name foo
Start/Stop VM
multipass stop foo
multipass start foo
Open a Shell
This command is particularly helpful to run commands in your Linux VM like watching pods and running Kubernetes commands.
multipass shell foo
View Instances
multipass list
Clean Up
multipass delete foo
multipass purge
What’s Next?
In the next lesson, we’ll use the quickstart command to set up our own Entando instance on Kubernetes.
