The following describe how to install K3S on the master and agent nodes. Note the IP address of the k3s-master – it will be needed later when installing K3S on the agent node. The output should be similar to the following: Name State IPv4 Image Multipass launch -name k3s-master -mem 4G -disk 5G 18.04 multipass launch -name k3s-agent -mem 4G -disk 5G 18.04 Create and start the master node virtual machine:.Having installed Multipass, open a terminal window: For this I will need two virtual machines. I will create a Kubernetes cluster that consists of two nodes one master and one agent. ![]() Instructions on how to install kubectl can be found here. Instructions on how to install Multipass can be found here.Īs before, kubectl is the Kubernetes command-line cluster management tool. Toolsīefore installing K3S, the following tools need to be installed on the computer that is to act as a host for the virtual machines:Ĭanonical’s virtual machine in which instances of Ubuntu can be run. To prepare for K3S, I will install a couple of tools that I will need and then create the virtual machines in which K3S will run. – Kind does not support the LoadBalancer type.K3S is more similar to a real Kubernetes cluster.ĭuring the short time that I have been working with Kind, I have encountered two issues which made me have a look at K3S:.Perhaps not Google-scale production ready, but enough for my needs I suspect. ![]() The astute reader will recall a recent article of mine in which I described how to run a Kubernetes cluster in Docker and may wonder why I now have moved on to K3S instead of Kind. Multipass can be run in Windows, Mac OS X and Linux so the procedure described in this article should apply to all the above mentioned environments though I have only tested it in Mac OS X. In addition, I will describe how to configure kubectl, the Kubernetes command-line cluster management tool to manage the K3S cluster from outside of the virtual machines in which the cluster will run. This is another Kubernetes-related notebook entry in which I will document the procedure for setting up a Kubernetes cluster using K3S in virtual machines created with Canonical’s Multipass.
