Jun 7, 2022 · It’s easy to install and set up for a Docker environment. No redundancy. Currently I have written docker-compose. Docker-compose is inherently limited to the single node (single daemon). Stay tuned for more posts on those endeavors! K3d: This isn’t a distribution but instead a wrapper around K3s that runs your cluster inside a Docker container. Kubernetes is a powerful yet complex framework for managing containerized applications in a clustered environment. Use Cases for Docker and Kubernetes in Edge Computing Environments. Docker Compose is suitable for local development and small-scale deployments, as it lacks advanced scaling and orchestration features. Apr 16, 2016 · I would suspect that there are only a few features missing in k3d, as they are not supported in k3s, but for 95% of the development work, it should be totally sufficient. With Compose, you use a YAML file to configure your application’s services, and then, with a single command, you create and start all the services from your configuration. yml：配置文件，用于定义应用的服务、网络和卷等。 三、功能特性 1. Kubernetes vs docker-compose comments. Might be also OpenMediaVault (it appears you can run Docker easily on this) or Ubuntu or any other Linux. Mar 12, 2025 · The K3s server node is a host running with a control plane and datastore; the K3s agent node runs without any control plane or datastore. Rethinking the assumptions made with Docker Compose in the new syntax is going to work out a lot better in the long run. Here When worker was made down the container moved to Feb 4, 2025 · K3s, a lightweight version of Kubernetes, is specifically designed for edge and IoT environments, providing the full orchestration benefits of Kubernetes with reduced resource requirements. Anyone has any specific data or experience on that? Dec 3, 2021 · Built-in container orchestration: Unlike Docker, which relies on Docker Compose and Swarm mode to manage multiple containers, Kubernetes is built from the ground up as a platform for container orchestration. Minikube can also be used to run third party dependencies such as MySQL and other tools. the limited single-process container approach of Docker is the main reason I chose lxd over Docker. Compose offers many advantages, such as having your configuration stored as code, making it easy to maintain and expand upon. r/kubernetes. Docker and Compose will simplify portability and innovation of Apps. Docker for Mac even ships with minikube out of the box now. Discussion Hey there! I’ve been using one raspberry pi for a while with a docker-compose setup and it was a great experience: everything Feb 6, 2023 · Kubernetes 生態圈有一大堆媲美 Docker Compose 便利性的工具（譬如我愛用的 Skaffold）。不過，如果你實在太想念 Docker Compose，有兩種做法： 可直接沿用舊的 Docker Compose，但是需要將 Podman 啟動成 daemon 6 。 Docker Compose 的安裝方法： Oct 13, 2021 · Docker Swarm アプリケーションは、YAML ファイルや Docker Compose を使用してサービスまたはマイクロサービスとしてデプロイできます。 Kubernetes では、名前空間、Pod、デプロイなどを組み合わせてさまざまな形でデプロイできます。 Hi everyone, looking for a little bit of input on revamping my lab to go full k3s instead of doing docker (compose) per individual node like I am. K3s is going to be a lot lighter on resources and quicker than anything that runs on a VM. You only need a docker-compose. Docker Swarm. Sep 28, 2021 · Docker-Compose Docker-Compose 是用来管理你的容器的，有点像一个容器的管家，想象一下当你的Docker中有成百上千的容器需要启动，如果一个一个的启动那得多费时间。有了Docker-Compose你只需要编写一个文件，在这个文件里面声明好要启动的容器， Also just the question of short term wins vs long term use. E. I understand I could use docker swarm, but I really want to learn the Kubernetes side of things and with my hardware below I think k3s is (probably?) the right fit. My reason for trying k3s is to learn more about clustering and kubernetes. Docker Swarm没有像Kubernetes中的RBAC那样的访问控制层级，因此创建和维护安全模型需要额外的努力。 2. 编写docker-compose. Docker Compose is ideal for development, testing K3s 1. A lot easier to install and reason about; Built into the official Docker CLI; More lightweight and has less moving parts; Compatibility with docker-compose. Apr 8, 2024 · K3s as an alternative. I'm just going to try other things on k3s. I can run VM, LXC or Docker whenever I want. Docker Compose and k3s are two widely used tools in the containerization landscape. In the case of a system that is not big but have a potential to grow, makes sense to use k3s and build a infrastructe model compatible with docker-compose allows you to coordinate MANY containers in the same computer using 1 YAML file instead of manually running commands for each container. yml: Nov 8, 2024 · Use Docker Compose if your application is small-scale, doesn’t need high availability, and won’t experience frequent scaling needs. It can make K3s deployment even easier and safer. Kubernetes vs. Container runtime, Kube proxy, and other components are included in K3s Agent. I dunno, go read truneas forums but i recall it will be custom solution via non-modifiable by user docker-compose apps in the app menu. The plugin is based on the amazing SUSE K3s, a lightweight Kubernetes distribution built for IoT & Edge computing which makes it ideally for running on SBC like Raspberry Pi. yaml. However, there may be some situations where Docker Compose and Docker Swarm make sense. I read that Proxmox recommends running docker in a VM rather than LXC. Jul 15, 2023 · Docker Swarm 和 Docker Stack 不仅仅是 Docker 和 Docker Compose 的补充，更是他们的自然延伸。如果你已经习惯于使用 Docker 和 Docker Compose 来创建和管理单个主机上的应用，那么你会发现 Swarm 和 Stack 提供了一个熟悉且一致的界面，用于扩展应用到多个主机上。 As a kubernetes DevOps with a docker host and a kubernetes cluster at home - docker is far more user friendly for home use. On the other hand, k3s is detailed as "Lightweight Kubernetes. Mar 19, 2024 · In this article, we’ve seen the difference between Docker Compose and Kubernetes. I used K3S in my cluster because it is a lightweight, stripped-down version of Kubernetes that’s ideal for running on resource-constrained devices like Raspberry PIs I plan to use in my home lab cluster. The only thing I worry about is my Raspberry handling all of this, because it has 512mb ram. I'm using Ubuntu as the OS and KVM as the hypervisor. However, compared to Kubernetes, Docker Swarm has limited offerings. Docker Compose simplifies the deployment of multi-container applications, while Kubernetes provides robust management and scaling capabilities for containerized workloads. containerd是从Docker中分离出来的一个项目，可以作为一个底层容器运行时，现在它成了Kubernete容器运行时更好的选择。 不仅仅是Docker，还有很多云平台也支持containerd作为底层容器运行时，具体参考下图。 K8S CRI Apr 20, 2024 · It also leverages Docker containers as nodes, making it compatible with any platform that supports Docker.
