K3s vs minikube reddit github. k3s for small (or not so small) production setups.

K3s vs minikube reddit github I use K3S heavily in prod on Minikube is much better than it was, having Docker support is a big win, and the new docs site looks lovely. Oracle Cloud actually gives you free ARM servers in total of 4 cores and 24G memory so possible to run 4 worker nodes with 1 core 6G each or 2 worker nodes with 2 cores and 12GB memory eachthen those of which can be used on Oracle Kubernetes Engine as part of the node pool, and the master node itself is free, so you are technically free but you are right, there is no difference between Debian Stable and Ubuntu LTS server (that is not bloated because it's the used to deploy in on-premise and cloud server editions), because k3s try to maintain support on all these. If you intend to manage a cluster in production I’d recommend learning on vanilla, and once you’ve got it down and start finding it annoying migrate to rancher/rke2, or k3s. minikube; kind; k3d; Performance Showdown. /minikube-linux-amd64 start.

Someone reported a different flavor of k8s is working below, so this sounds like possibly a minikube bug. Maybe it's a distro integration issue. k3s + k3d: Minikube: I 've been working on a home project with minikube on fedora 34, and ~1 week ago it seems like the dns service in my cluster stopped working, and my services can only communicate via ip. Gaming. I assume K3s is managed just like minikube, e. It is only a single instance so you aren’t gaining the advantages of a scalable cluster of servers. If you’re after compatibility and a simulation close to reality, minikube is your safest bet. The main downside of Minikube is that it's only designed for testing. That Solr Operator works fine on Azure AKS, Amazon EKS, podman-with-kind on this mac, podman-with-minikube on this mac. The commands for setting up the cluster vary between microk8s, k3s, k8s etc (so deployment is different), but once your cluster is up and running, it should be the same (kubectl). Minikube's main advantages are that it's extremely lightweight and very easy to install and use.

From the site: K3s is a highly available, certified Kubernetes distribution designed for production workloads in unattended, resource-constrained, remote locations or inside IoT appliances I'd happily run it in production (there are also commercial managed k3s clusters out there). In this post we’ll have a look at Minikube vs kind vs k3s and compare their pros and cons and identify use cases for each of them. R. In a test run, I created a 500-node highly available cluster (3 masters, 497 worker nodes) in just under 11 minutes - though this was with only the public network, as private networks are limited to 100 I'm not sure how much advantage there is, or compared against what, but it works. on k0s compared to k3s, you won't find some pre-installed handy add-ons like ingress (traefik), service load balancer (servicelb) and storage (local-storage). I chose k3s because it's legit upstream k8s, with some enterprise storage stuff removed. k3s is a great way to wrap applications that you may not want to run in a full production Cluster but would like to achieve PureLB is a load-balancer orchestrator for Kubernetes clusters. I use helm, or yaml files to make deployments but they all fail for one reason or another. Minikube is the closest to an official mini distribution for local testing and development, it is run by the same foundation as K8s. Many companies use managed Kubernetes instances in cloud providers, so if you also want to learn that then it's worth getting a free tier account at some of the cloud providers and practicing there. My single piece of hardware runs Proxmox, and my k3s node is a VM running Debian. At home I use minikube (Win10) for chart / manifest dev and run my workloads on K3s (x64 & ARM hybrid cluster). 1. I run bone-stock k3s (some people replace some default components) using Traefik for ingress and added cert-manager for Let's Encrypt certs.
