What if you need quickly to launch virtual machine instances running Ubuntu for development and testing purposes.
\nMultipass from Canonical can be the right tool for this. You can even customize the instances during launch by using Cloud-init in order to simulate a small cloud deployment from your laptop or desktop.
\nSo, in this short blog post, I will talk about this tool and demonstrate how easy it is to use it.
\n<\/p>\n
Multipass is a lightweight Virtual Machines Manager (VMs) and can be the ideal way for launching VM’s for developers.
\nIt can be installed either on Linux, MacOs or Windows.
\nMultipass use KVM on linux, Hyperkit on MacOs and Hyper-V on Windows and supports metadata for cloud-init.
\nIt allows you to launch a fresh Ubuntu environment with a single command and it is also possible to simulate a small cloud deployment.<\/p>\n
I’m going now to show you how to install multipass locally on my MacBook but you can also install the tool on Windows or on Linux. To provision and customize the virtual machines to simulate a small cloud deployment, I will use “cloud-init” from Canonical That’s all you have to do to install Multipass VM manager and deploy Virtual Machines.

\nYou have 2 options to achieve this. brew (https:\/\/brew.sh\/), the package manager or the mac installer.
\nAs brew is already installed, let’s do it with brew.
\n(\u2388 |docker-desktop:default)sme@Said-MacBook-Pro-3 K8S % brew install --cask multipass<\/span>

\nLet’s create the 3 VMs.

\nDepending on which platform you are, you may need to start the VMs after they have been launched.
\nOn my desktop, they were all running.
\n(\u2388 |docker-desktop:default)sme@Said-MacBook-Pro-3 K8S % multipass list<\/span>
\nName State IPv4 Image
\ncontrol Running 198.19.0.1 Ubuntu 20.04 LTS
\nnode1 Running 198.19.0.2 Ubuntu 20.04 LTS
\nnode2 Running 198.19.0.3 Ubuntu 20.04 LTS<\/code>
\notherwise start them as following:
\n(\u2388 |docker-desktop:default)sme@Said-MacBook-Pro-3 K8S % multipass start --all<\/span><\/code><\/code>
\nTo check and validate if the deployment was successful, log on the first VM and run
\nubuntu@control:~$ kubectl get nodes<\/span>
\nNAME STATUS ROLES AGE VERSION
\nnode1 NotReady 5m12s v1.19.3
\nnode2 NotReady 6m33s v1.19.3
\ncontrol NotReady master 3m12s v1.19.3<\/code>
\nAs you can notice above, the status is “NotReady” and this is because the CNI (Container Nerwork Interface) plugin is not installed.<\/p>\nConclusion<\/h2>\n
\nWith this tool you can rapidly test your latest developments, so give this tool a chance. In a next blog, I will use this environment and show how to install “Calico”, one of the most famous CNI.<\/p>\n","protected":false},"excerpt":{"rendered":"
