禁漫噜噜社：探索二次元的无限可能，释放你的无限想象
此文的目的构建企业级应用从开发、部署、运行的一个缩影整个流程虽然相对简陋但是麻雀虽小五脏俱全打通了服务编写、镜像构建、部署。
为了小伙伴们大致了解DevOps和K8s集群部署有一个初步认识。
整体思路是1编写一个及其简单的SpringBoot项目2基于Dockerfile构建镜像和Containerd3发布到k8s集群下属本地containerd容器池4编写k8s对象、kubectl apply一键运行。
前提条件1已安装k8s集群服务2已经安装Docker一构建SpringBoot项目1基础环境JDK21SpringBoot

tar三发布到k8s中运行1到k8s的woker节点上Docker镜像我们上传的虽然是docker镜像当前k8s当中运行的是containerd这是可以兼容的。
问题不大。
