There's also a lot of management tools available (Kubectl, Rancher, Portainer, K9s, Lens, etc. Both provide a cluster management abstra K8s is short for Kubernetes, it's a container orchestration platform. Longhorn handles everything and has been doing so for a while. K3s is good enough for learning. You are having issues on a Raspberry Pi…. In particular, I need deployments without downtimes, being more reliable than Swarm, stuff like Traefik (which doesn't exist for Docker Swarm with all the features in a k8s context, also Caddy for Docker wouldn't work) and being kind of future-proof. I have a couple of dev clusters running this by-product of rancher/rke. IIUC, this is similar to what Proxmox is doing (Debian + KVM). Production readiness means at least HA on all layers. It helps engineers achieve a close approximation of production infrastructure while only needing a fraction of the compute, config, and complexity, which all result in faster runtimes. ” To be honest even for CI/CD can be use as production. Portainer started as a Docker/Docker Swarm GUI then added K8s support after. Single master k3s with many nodes, one vm per physical machine. as someone who has been using Longhorn with Micro Thinkcentre nodes w/ NVME SSD storage Longhorn has been the easiest, most reliable k8s storage interface I’ve used. It's the foundation for several other distros and is about as minimal as you can get, in terms of add-ons. Bare Metal K8S vs VM-Based Clusters I am scratching my head a bit, wondering why one might want to deploy Kubernetes Clusters on virtual machines. A couple of downsides to note: you are limited to flannel cni (no network policy support), single master node by default (etcd setup is absent but can be made possible), traefik installed by default (personally I am old-fashioned and I prefer nginx), and finally upgrading it can be quite disruptive. I use k3s whenever I have a single box, vanilla kubeadm or k3s join when I have multiples, but otherwise I just use the managed cloud stuff and all their quirks and special handling.

It is also the best production grade Kubernetes for appliances. I know k8s needs master and worker, so I'd need to setup more servers. Ultimately, the choice between Minikube, Kind, and K3s hinges on specific project requirements, resource availability, and preferred workflows. Though k8s can do vertical autoscaling of the container as well, which is another aspect on the roadmap in cf-for-k8s. 6 years ago we went with ECS over K8s because K8s is/was over engineered and all the extra bells and whistles were redundant because we could easily leverage aws secrets (which K8s didn’t even secure properly at the time), IAM, ELBs, etc which also plugged in well with non-docker platforms such as lambda and ec2. Having experimented with k8s for home usage for a long time now my favorite setup is to use proxmox on all hardware. Currently running fresh Ubuntu 22.
