This mini-cluster by Canonical is similar to the previous one: the cluster nodes require a manual setup and they can run on any Linux instances connected to the first (master) node over TCP/IP.
CONTROLPLANE MAC ALTERNATIVE SOFTWARE
The software is installed in the same way as in a regular Kubernetes cluster – by declaring the necessary primitives (you can use Helm and other such tools). It does not feature support for cloud providers by default (however, you can add that during the startup). K0s is as minimalistic as possible: it is a plain vanilla Kubernetes without any modules or plugins. Essentially, you can use any CNI you like, since k0s does not restrict the Kubernetes configuration in any way.įor user convenience, k0s provides auto-completion scripts for various shells: Bash, zsh, fish, and PowerShell (using WSL). Calico serves as the default CNI while kube-router is also available. In addition, you can mount hostPath volumes to the Pods. The containerd daemon manages and runs containers in Pods. To uninstall the k0s cluster, you first need to stop the service ( k0s stop) and then invoke the reset command to remove all k0s-related files from the host. This other server can run in a container or on a VM: all you have to do is ensure the API server’s network availability to register a node in the cluster. Next, generate an authentication token, which you will use to join the node to the cluster.
CONTROLPLANE MAC ALTERNATIVE INSTALL
To add a node to the k0s cluster, download and install the k0s binary file on the server intended to be used as the worker node. You can use k0s kubectl to create other Kubernetes objects: namespaces, Deployments, etc. K0s includes the kubectl CLI tool to connect to the Kubernetes API: k0s kubectl get nodes Now you can access it as a cluster node (the master node by default): k0s install controller systemctl start rvice Note that only the root user can run it.Īfter the installation is complete (all you need to do is copy the file to /usr/local/bin), start k0s as a service using a helper script. Thus, the cluster can only run on that system (see the end of the article for more information on supported host systems). All you need to do is download the current version of it from the project repository and you can proceed to configure and use the cluster. The name of the project speaks for itself: it is hard to imagine a system any more lightweight since it is based on a single, self-sufficient (statically built) file. At the end of the article, we provide a comparison table detailing the main features of the solutions.
Fortunately, they are all relatively well-documented (both on the official websites and in the CLIs), which significantly speeds up the learning process and renders them easy to use. This article reviews some of the most popular ones, helping you to better understand them and choose the right tool. The one you choose will depend on your needs and preferences. All these solutions come with different designs and capabilities. You can run them on your desktop or laptop, tinker with primitives, build a new structure, and then delete them without any hesitation when the experiment is over.ĭevelopers worldwide have met this demand by inventing various solutions that allow you to fire up a lightweight Kubernetes environment quickly and easily. In cases like these, Kubernetes mini-clusters come to the rescue. To do that, what you need is an easy-to-set-up sandbox to test your idea without taking too much risk. This scenario is familiar to most people who’ve had experience with Kubernetes.
So you’ve come up with an idea to automate, unify, or transform something in a cluster, but you don’t want to risk ruining the cluster.
