Speed of k3s is its best advantage and I’m sure that alone will make lots of people use it. I will keep watching kind and k3s to see if they get better. Considered k3s and k0s as single binary because they have no dependencies and do no downloads during the set up processĪfter spending hours testing and benchmarking these tools I’ll probably continue using minikube because it’s so easy to use.Subtracted ease of use points for each obstacle encountered during the installation of wordpress helm chart (missing addon, no default kubeconfig).k3s will run at boot if installed by following the quick start guide minikube can actually run at but only if you define the service manually.When comparing distributions I made the following assumptions: Cluster setup time includes binary downloads but excludes dependencies (e.g.Counted the number of processes on the clean snapshot and subtracted from the process count after setting up the cluster.Used Apache Bench command “ab -n 1000 -c 5 to get the average response time on WordPress homepage.Installed WordPress using Bitnami WordPress helm chart.No port-forwarding during benchmarks because port-forwarding was significantly slower.All tests and benchmarks done on a clean virtual machine snapshot with 2 cores.

minikube uses “docker” driver recommended in the documentation.Benchmarkĭuring testing and benchmarks I made some choices to make it as fair as possible: Cluster comes with everything you need but not used as widely as minikube. Resource-wise kind scored average and did great in the benchmark. kind requires docker to be installed on your system with the right permissions. It hasn’t got a stable release yet so I wouldn’t switch to it just yet. “kind” stands for “Kubernetes in Docker”. Similar to minikube, kind is also maintained by the Kubernetes team but unlike minikube it only works with docker. For that reason it got the worst ease of use score.

I had to set up helm and install openebs. There isn’t even a command to install it. K0s does not come with a storage handler. The average response time was similar to the response times achieved with microk8s. k0s, like k3s doesn’t have any dependencies.īecause of it’s low resource footprint I was surprised by the benchmark results. You can add k0s to startup by using “k0s install controller” command or can run it quickly using “k0s controller” command. k0s binary is massive (170MB) compared to k3s (50MB). Like k3s, k0s also comes as a single binary which achieves a very quick setup times.

helm works out of the box with minikube, but with k3s you have to extract kubeconfig from kubectl using “k3s kubectl config view –raw”). It also lacks the shortcuts useful for beginners (e.g. K3s is very easy to use but as it’s not as widely used external tool support for it is not as good as minikube. Although it comes with both storage and DNS installed, it is also very light. k3s binary contains all the necessary cluster components so the cluster setup is very quick (the quickest of the 5 distributions). K3s is a distribution from Rancher and is a CNCF project. During benchmarking I had issues with helm v3 packaged with microk8s because it was an early release which had a bug. Microk8s is the only distribution that disables DNS by default. Storage and DNS addons are disabled by default so they need to be enabled if persistence and DNS. I am not sure what the slowness was caused by but my guess is its resource use. Internally MicroK8s uses containerd as the container runtime which is bundled into the snap package.ĭuring the benchmark microk8s did the worst. It’s a single “snap” command to install on Ubuntu systems. MicroK8s is Canonical‘s way of getting into Kubernetes market. For docker driver to work, docker has to be installed on the system and the current user has to have the right permissions. Minikube supports various “driver”s which allow you to run in different set-ups (virtualbox, docker, bare-metal, etc). Most development tools support minikube out of the box. Its default configuration makes it very easy to get started. Minikube is the oldest and most popular Kubernetes distribution for local environments. This post contains benchmarks and reviews of the following Kubernetes distributions:

Question is what’s the best Kubernetes distribution for local use? Local Kubernetes Distributions They tend to use minimal resources which is ideal. There are plenty of Kubernetes distributions available that can be used to install Kubernetes locally.
