I built a free hands-on DevOps lab instead of another tutorial course

I’ve been building a side project called Real DevOps Lab. The idea came from something I kept seeing with DevOps learning: People watch Linux, Docker and CI/CD tutorials, but when something actually breaks, they don't know where to start troubleshooting. So instead of creating another video course, I built a small hands-on project. The first free project takes you through: - running a real application - containerizing it with Docker - building it with CI/CD - deploying it to a

AI 分析

痛点:DevOps 学习者看完 Linux/Docker/CI-CD 教程后,遇到真实故障仍不知从何排障,缺乏可动手的 incident 实操环境。

目标用户:DevOps/SRE 初学者、转行者和准备面试的工程师,以及需要新人上手培训的小团队。

证据:People watch Linux, Docker and CI/CD tutorials, but when something actually breaks, they don't know where to start troubleshooting. / Right now I'm trying to validate the idea before building more content. / The project is free

变现:Freemium:免费入门 lab 引流,付费订阅解锁进阶 incident 题库、自动评分与解析;后续可做企业内训授权、面试实操题库、认证路径。

MVP:2 周内做 3-5 个 Linux/Docker 排障场景(如容器在跑但应用不可达、端口冲突、环境变量错误、CI 构建失败),用现成容器 + 浏览器终端(ttyd/wetty 或 Killercoda 托管)提供一键环境,配自动校验脚本判断是否修好,并给出分步解析。

竞品:KodeKloud、SadServers、Killercoda、A Cloud Guru / Pluralsight、Instruqt、Linux Upskill Challenge

摘要:一位开发者在 r/SideProject 发布免费的 Real DevOps Lab,用真实应用容器化、CI/CD 部署和排障 incident 替代视频教程,覆盖 Docker 容器在运行但应用不可访问等场景,GitHub 已开源 starter-app。作者明说项目仍免费、当前只是「验证想法」,因此没有付费意愿或收入数据支撑,但痛点明确、单人可做,挑战在于 KodeKloud、SadServers、Killercoda 等成熟竞品已占据排障实操赛道。
