Day 23 ✅ Survived my first merge conflict 💥 Lesson: it’s not an error, it’s collaboration in action. #Git #GitHub #DevOps #LearningInPublic
Day 22 ✅ Branching strategies aren’t one-size-fits-all. GitHub Flow vs GitFlow vs Trunk-based → tradeoffs everywhere. #Git #GitHub #DevOps #VersionControl #LearningInPublic
Day 21 ✅ Forks → Pull Requests → Code Reviews. GitHub is less about code, more about collaboration. #GitHub #DevOps #Collaboration #LearningInPublic
Day 20 ✅ GitHub clicked today. It’s not just “remote Git”… it’s the global teamwork hub 🌍. Push → Pull → PR → Merge. #GitHub #Git #DevOps #Collaboration #LearningInPublic
Day 19 ✅ Learned Git tags → versioned releases 🎯 Created aliases (git st, git co) Repo productivity just leveled up 🚀 #Git #DevOps #Productivity #LearningInPublic
Day 18 ✅ Discovered Git’s cleanup toolkit: diff stash clean Feels like keeping my repo tidy just got 10x easier 🧹 #Git #DevOps #VersionControl #LearningInPublic
Day 17 ✅ Git mistakes aren’t scary anymore 🎉 reset, revert, reflog = my new lifelines. Now I can experiment without fear 💪 #Git #DevOps #VersionControl #LearningInPublic
Day 8 of #100DaysOfDevOps Installed Ansible 4.10.0 on a Jump host 🌊 Lesson learned: Global install ≠ local install ⚠️ sudo isn’t optional 🛡️ Pin versions or automation breaks 😅 #DevOps #Ansible #Linux #Automation #LearningByDoing
Day 25 ✅ CI/CD → automation magic unlocked ⚡ GitHub Actions running builds/tests after push = WOW. #DevOps #GitHub #CICD #Automation #LearningInPublic
Day 16 ✅ Git “detached HEAD” nearly broke my brain 😂 But now I get it → moving around history & commits safely is POWER. Did you panic the first time you hit detached HEAD? #Git #DevOps #VersionControl #LearningInPublic
Day 7 of #100DaysOfDevOps 🚀 Disabled direct SSH root login on xFusionCorp app servers 🔒 ✅ Why: root SSH = huge risk ✅ How: PermitRootLogin no + sshd -t + restart ✅ Result: root login blocked, normal users unaffected #DevOps #Linux #Security #Automation @KodeKloudHQ
Day 6 of #100DaysOfDevOps ✅ Mixed-up production files? Fixed it without breaking anything: SSH to prod (banner@stapp03) find files owned by user siva cp --parents → preserve folder structure Verified counts & ownership #Linux #SysAdmin #DevOps
Day 7 of #100DaysOfDevOps ✅ Generated SSH keys (ssh-keygen -t rsa -b 4096) Copied to sudo users via ssh-copy-id Verified login w/o password Fixed .ssh & authorized_keys perms #Linux #DevOps #SSH #Automation
Day 6 of #100DaysOfDevOps ✅ Installed cronie & set up a test cron job to write "hello" every 5 mins. Lessons: Cron runs per user; root crontab ≠ normal user */5 * * * * = every 5 mins Automation = fewer errors, more reliability #DevOps #Linux #LearningInPublic
Day 5/100 – SELinux 🛡️ Today I: ✅ Installed SELinux packages ✅ Disabled it in config (no reboot yet) ✅ Prepped server for future policy testing Takeaway: Security isn’t just “enable/disable”. It’s about timing, validation & minimizing risk. #100DaysOfDevOps #Linux #DevOps
Day 4 of #100DaysOfDevOps Created a service user on Linux without a home dir. Small task, big lesson: ✅ Correct server ✅ Least privilege ✅ Clean & secure It’s the small, precise actions that keep infra secure & scalable. 💻🔧 #DevOps #Linux #Automation #Security
Day 4 of #100DaysOfDevOps ✅ Task: Make a backup script executable. Lesson: chmod a+x ≠ enough. Scripts need read + execute. ✅ Correct fix → chmod 755 zurl.co/1rWaB (rwxr-xr-x: owner full, others read+exec) Don’t just run commands. Understand why. #DevOps #Linux
Day 15 ✅ Learned branch cleanup (delete after merge) Understood rebasing for clean commit history Git history now makes sense Merge vs Rebase → which side are you on? #Git #DevOps #VersionControl #LearningInPublic
Day 14 ✅ Learned Git branching 🌿 Merge requests = collaboration guardrails Version control = teamwork philosophy 💡 #Git #DevOps #Collaboration #LearningInPublic
Day 13 ✅ Practiced git add, commit, push Learned how to init projects with git init Finally feeling the Git rhythm 🎶 #Git #DevOps #VersionControl #LearningInPublic
