Get started with Multipass - Linux

Errors or typos? Topics missing? Hard to read? Let us know or open an issue on GitHub.

Multipass is a flexible, powerful tool that can be used for many purposes. In its simplest form, it can be used to quickly create and destroy Ubuntu VMs (instances) on any host machine. Used to a fuller extent, Multipass is a local mini-cloud on your laptop, allowing the testing and development of multi-instance or container-based cloud applications.

This tutorial will give you an understanding of how Multipass works, and the skills you need to use its main features.


Install Multipass

Multipass is available for Linux, macOs, or Windows. To install it on your OS of choice, please follow the instructions given in the how-to guides. Note: This tutorial demonstrates use on Linux, specifically Ubuntu, but the experience on any OS should be similar.

Create and use a basic instance

From the application launcher, let’s start Multipass. In Ubuntu, press the super key and type Multipass, or find Multipass in the Applications panel in the lower left of the desktop.

Once we’ve launched the application, we should see the Multipass tray icon in the upper right section of the screen:

Let’s click on the icon, then on “Open Shell”.

Clicking this button does many things in the background: it creates a new virtual machine (instance), named primary, with 1GB of RAM, 5GB of disk, and 1 CPU; installs the most recent Ubuntu LTS release on that instance; mounts our $HOME directory in the instance; and opens a shell to the instance, announced by the command prompt ubuntu@primary. You can see elements of this in the printout below.

Launched: primary                                                               
Mounted '/home/<user>' into 'primary:Home'

To check for new updates run: sudo apt update


Let’s test it out! As we just learned, the previous step automatically mounted our $HOME directory in the instance. Let’s use this to share data with our instance. More concretely, let’s create a new folder in our $HOME directory called Multipass_Files:

As you can see, I’ve added a readme file in this shared folder. Let’s check for the folder and read the file from our new instance:

ubuntu@primary:~$ cd ./Home/Multipass_Files/
ubuntu@primary:~/Home/Multipass_Files$ cat 
## Shared Folder

This folder could be a great place to keep files that need to be accessed by both your host machine and Ubuntu VM!


Congratulations, you’ve got your first instance!

This instance is great for when we just need a quick Ubuntu VM, but let’s say we want a more customised instance. Multipass has us covered there too!

Optional Exercises

Exercise 1:
When you clicked on Open Shell just now, what happened in the background was the equivalent of the CLI commands multipass launch –name primary followed by multipass shell. Open a terminal and try multipass shell (if you didn’t follow the steps above, you will have to run the launch command first).

Exercise 2:
In Multipass, an instance with the name primary is privileged. For example, it is the default argument of multipass shell. In two terminal instances, check multipass shell primary and multipass shell. Both commands should give the same result.

Create a customised instance

Multipass has a great feature to help us get started creating customised instances. Let’s open a terminal and run the command multipass find. This shows us a list of all of the images we can launch through Multipass currently.

Let’s launch an instance running Ubuntu 22.10 (“Kinetic Kudu”) by typing the command multipass launch kinetic

Now we have an instance running that has been named randomly by Multipass; in my case, it is called “coherent-trumpetfish”.

$ multipass launch kinetic
Launched: coherent-trumpetfish

We can check some basic info about our new instance by running the following:

multipass exec coherent-trumpetfish -- lsb_release -a

This tells multipass to execute the command lsb_release -a on the “coherent-trumpetfish” instance.

$ multipass exec coherent-trumpetfish -- lsb_release -a
No LSB modules are available.
Distributor ID:	Ubuntu
Description:	Ubuntu 22.10
Release:		22.10
Codename:		kinetic

Perhaps after using this instance for a while, we decide what we really need is the latest LTS version of Ubuntu, with a more informative name and a little more memory and disk. We can delete the “coherent-trumpetfish” instance by running

multipass delete coherent-trumpetfish

Let’s now launch the type of instance we’re looking for by running this:

multipass launch lts --name ltsInstance --memory 2G --disk 10G --cpus 2

Manage instances

Now let’s confirm this new instance has the specs we’re looking for by running multipass info ltsInstance

$ multipass info ltsInstance                             
Name:           ltsInstance
State:          Running
Release:        Ubuntu 22.04.1 LTS
Image hash:     3100a27357a0 (Ubuntu 22.04 LTS)
CPU(s):         2
Load:           1.11 0.36 0.12
Disk usage:     1.4GiB out of 9.5GiB
Memory usage:   170.4MiB out of 1.9GiB
Mounts:         --

We’ve created and deleted quite a few instances now. Let’s run multipass list to see what instances we currently have.

$ multipass list                                         
Name                    State             IPv4             Image
primary                 Running     Ubuntu 22.04 LTS
coherent-trumpetfish    Deleted           --               Not Available
ltsInstance             Running     Ubuntu 22.04 LTS

We have two instances currently running, the primary instance and our LTS machine with customised specs. Our “coherent-trumpetfish” instance is still listed, but its state is “Deleted”. We can recover this instance by running multipass recover coherent-trumpetfish, but for right now let’s delete the instance permanently by running multipass purge. Running multipass list again confirms the instance is now permanently deleted:

$ multipass list
Name                    State             IPv4             Image
primary                 Running     Ubuntu 22.04 LTS
ltsInstance             Running     Ubuntu 22.04 LTS

We’ve now seen a few ways to create, customise, and delete an instance. Now let’s put those instances to work!

Put your instances to use

Run a simple web server

Let’s go back to that customised LTS instance we created. Take note of its IP address revealed by multipass list in the previous step, then run multipass shell ltsInstance to open a shell in the instance.

From the shell, we can now run:

sudo apt update

sudo apt install apache2

Now, let’s open a browser and type in the IP address of the instance into the address bar. We should now see the default Apache homepage.

Just like that, we’ve got a web server running in a Multipass instance!

We can use this web server locally for any kind of local development or testing we like. If however, we want to access this web server from the internet (e.g. from a different computer), we need an instance that is exposed to the external network.

Launch from a Blueprint to run Docker containers

Some environments require a lot of configuration and setup. Multipass Blueprints are instances with a deep level of customization. The Docker Blueprint, for example, is a pre-configured Docker environment with a Portainer container already running. We can launch an instance using the Docker Blueprint by running multipass launch docker --name docker-dev

Once that’s finished, let’s run multipass info docker-dev to note down the IP of the new instance.

$ multipass launch docker --name docker-dev
Launched: docker-dev
$ multipass info docker-dev
Name:           docker-dev
State:          Running
Release:        Ubuntu 22.04.1 LTS
Image hash:     3100a27357a0 (Ubuntu 22.04 LTS)
CPU(s):         2
Load:           1.50 2.21 1.36
Disk usage:     2.6GiB out of 38.6GiB
Memory usage:   259.7MiB out of 3.8GiB
Mounts:         --

Let’s take the IP address starting with “10” and paste it into our browser, then add a colon and the portainer default port, 9000, like this: This will take us to the Portainer login page, where we can set a username and password.

From there, let’s select a local docker environment.

From there, we can click into the newly created “local” docker endpoint, navigate to the app templates page, and select NGINX

From the Portainer dashboard, we can see the ports that nginx has available. We can navigate to the IP address of our instance followed by that port number to see that we indeed have nginx running in a docker container inside Multipass!

Thanks for taking the time to report that, @mscho7969 - we appreciate your help :slight_smile: We’ve fixed the links now so hopefully there won’t be any more problems!


Under the ‘Create a customised instance’ heading, there is a wrong instance name (close to the end).

Wrong: deluxe-ghoul
Right: coherent-trumpetfish

We can delete the deluxe-ghoul instance by running

Good catch, @itecompro. Thanks!
