Day 12 – #30DaysOfDevOps Not rushing ahead anymore. I’m giving myself 7 days to properly revise Linux, Git, Shell, Docker, AWS, and CI/CD. I’m rebuilding things, breaking them, and fixing them — especially AWS + Docker + Jenkins pipelines. Not giving up. 💪 #DevOps #aws #linux

Day 11 of #30DaysOfDevOps Learned Jenkins fundamentals and installed Jenkins on an EC2 instance by connecting from local Ubuntu via SSH. Understood how Jenkins fits into CI CD pipelines for automated builds. #DevOps #Jenkins #CI #LearningInPublic

Day 10 of #30DaysOfDevOps Built Docker images using multi-stage builds and distroless images. Compared them to understand image size, security, and production readiness. #DevOps #Docker #Containers #LearningInPublic

Day 9 of #30DaysOfDevOps Deep-dived into Docker networking and tried building two-tier and three-tier architectures. Got frustrated while connecting services, but not giving up — this is where real learning happens. #DevOps #Docker #Networking #LearningInPublic

Day 8 of #30DaysOfDevOps Learned multi-stage Docker builds, Networking, and Docker volumes. Built a multi-stage Node.js project to create smaller, efficient, and production-ready images. Project-Link : github.com/ritikkumar55/3… #DevOps #Docker #NodeJS #LearningInPublic

Day 7 of #30DaysOfDevOps Started learning Docker. Built and published a Docker image by dockerizing a basic Express.js project and understood how containers simplify application deployment. #DevOps #Docker #Containers #LearningInPublic #linux

Day 6 of #30DaysOfDevOps Learned advanced Git concepts — revert, branches, and pull requests. Understood how PRs help with code review, collaboration, and safe changes in real projects. #DevOps #Git #GitHub #LearningInPublic

Day 5 of #30DaysOfDevOps Learned basic Git & GitHub commands — init, add, commit, push. Understood how version control is essential for collaboration and tracking changes in DevOps workflows. #DevOps #GitHub #LearningInPublic

Day 4 of #30DaysOfDevOps Explored shell scripting using Bash and Python. Built a few basic automation scripts and understood how scripting simplifies repetitive DevOps tasks. #DevOps #ShellScripting #Python #LearningInPublic @geeksforgeeks

Day 4 of #30DaysOfDevOps Learned Linux administration essentials — user & group management and package management. Understood how these basics are critical for server security, access control, and system maintenance. #DevOps #Linux #LearningInPublic @geeksforgeeks

✅ Day 3 of #30DaysOfDevOps Set up my AWS account and launched an EC2 instance. Started hands-on with Linux commands directly on the server and understood how Linux is used in real DevOps work. Slowly moving from theory to real systems #DevOps #AWS #Linux #LearningInPublic

Day 2 of #30DaysOfDevOps Learned Networking Fundamentals — OSI & TCP/IP basics, IP addressing & subnetting. Practiced core networking commands and covered security, DNS, and load balancing. #DevOps #TrainWithShubham #Networking #LearnInPublic

✅ Day 1 of #30DaysOfDevOps — Completed Learned what DevOps really is: culture + automation + shared ownership. Compared to traditional Dev/Ops silos, DevOps enables faster releases and better reliability. Saw how DevOps helped gfg reduce AWS costs. #DevOps @GeeksforGeeks
