Related topics Topic Replies Views Activity The 4 different distributions use different backend (K3s: embedded containerd, MicroK8S: containerd, KinD: Docker, kubeadm: VM) and different external address spaces, so they may run parallel on the same Ubuntu OS We’ve looked at four tools you can use to deploy your own Kubernetes cluster: Minikube, MicroK8s, K3s, and Kubeadm. 🙂 Lightweight – The single binary file is under 100MB, making it faster and less resource-hungry than K8s. Docker Swarm also provides microk8s is another installation option. MicroK8s supports a wider array of container runtimes, storage and networking plugins, and configuration options.

I contacted Canonical to ask their advice about the above, and was told that by default, MicroK8s installs the Calico network driver and kubeadm: Kubernetes tool for creating ground-up Kubernetes clusters. Locking down access prematurely, without knowing what potential use cases could arise, seems to make the least sense to me. kubeadm 1. Learning K8s: managed Kubernetes VS k3s/microk8s Reason why I ask is if I should bother learning the full fledge k8s or is learning with k3s/microk8s enough? Learn full fledged kubernetes and how to deploy it with kubeadm, the experience will be worth it.

There are several important differences between K3s and MicroK8s, including the following: System compatibility. net. kubeadm reset Share. Canonical, the open source company that is the main developer of MicroK8s, describes the platform as a “low-ops, minimal production” MicroK8s 的一个不错的特性是，只要集群节点总数达到或超过三个，它就会自动将您的集群配置为高可用性（意味着它有多个主节点）。 总体而言，MicroK8s 使用起来比 K3s 或 Minikube 稍微复杂一些，特别是因为它具有模 MicroK8s is the simplest production-grade upstream K8s. Complexity: Kubeadm clusters require significant setup and maintenance efforts, including configuring multiple nodes and components. 25. Everything else (kops, rke) is the easy way out and often just wraps kubeadm. A flatter learning curve – Preparing for The CKA & Diving into the Kubes I recently passed the Linux Foundation’s Certified Kubernetes Administrator (CKA) certification and thought I’d throw some notes together on how I prepared.
