We can launch multiple micro-instances running automated integration tests. We can safely play with alternative versions.
Ubuntu multipass software#
We can run software in isolation from your workstation. Everything that can be done with the Ubuntu Linux server, can be done with Multipass instances. Multipass virtual machines are fully functional Ubuntu LTS instances. We use Docker, VMWare, VirtualBox, cheap VPS, disposable instances in the cloud, and many other solutions. By using clean environments for testing and deployments we’re less vulnerable to “It Works on My Machine” syndrome. By installing third-party software on isolated environments we keep our workstations clean and healthy.
We agree that virtual machines and containers are the most useful tools in a developer’s toolbelt. You can also try my preparation and joining Ansible scripts (taking care to fill out the "masters" and "vmworkers" sections of the inventory) and let me know how it went.There are few more commands such as mount for mounting directories or transfer for copying files.
Ubuntu multipass windows#
Since the Windows virtual machine runs Ubuntu, the new node can be prepared in the usual way for Ubuntu so that the "kubeadm join" command can be run on it. Note Should you wish to reboot your Multipass machine you probably need to add this deletion somewhere it runs during bootup, however, I believe it to be safer practice to rather spin up fresh worker nodes than to reuse. The fact that the 192* adaptor listens indirectly on the host machine's LAN, gets us around the need to do these additions to the routing table. Therefore other nodes in a Kubernetes cluster will not be able to communicate with the virtual machine without the addition of routing rules. Multipass opened the outgoing traffic by using the host machine as a reverse proxy but did not open it for inward communication. However, try to ping the IP address from another machine and you will see that it is unreachable. The first adaptor on the internal subnet (172* here) is always created by Multipass.

Give the new switch a name, click the "External network" radio button and select the second network adaptor (not your primary adaptor!) from the dropdown box. Creating the Multipass VMĪfter downloading and installing Multipass, open Hyper-V and create a new external switch: As such knowledge of Ansible might be beneficial but is not required. A practice project to spin up a Kubernetes cluster with Ingress and MetalLB load-balancing using Ansible inspired the write-up and parts of that solution will be used.
Ubuntu multipass how to#
This posting requires a working knowledge of Kubernetes, especially how to prepare and join a worker node to the cluster. In this posting I will demonstrate an easy way to achieve this using 1) a secondary network adaptor and 2) Ubuntu Multipass to create the required virtual machine on Windows. Getting a Windows node to join a bare-bone Kubernetes cluster can be a daunting experience.
