How to properly learn Docker</p> <p>-Thank you</p> learning help docker Chandra Shekar Mon, 22 Dec 2025 17:09:59 +0000 https://dev.to/chandraa007b/day-1-with-docker-2enm https://dev.to/chandraa007b/day-1-with-docker-2enm <ol> <li><p>The Permission Headache I immediately hit a permission denied error. Instead of just using sudo every time (which is a bad habit), I learned how to add my user to the group: sudo usermod -aG docker $USER Note: You have to log out and back in for this to work!</p></li> <li> <p>Interactive vs. Detached I practiced the difference between:</p> <p>docker run -it ubuntu: Getting inside the container shell.</p> <p>docker run -d ubuntu: Letting it run in the background.</p> </li> <li> <p>Useful Commands I Used Today:</p> <p>docker ps -a (to see the ghosts of containers past)</p> <p>docker images (to see what's taking up space)</p> <p>docker exec -it (better than attach for jumping back into a running container)</p> </li> </ol> <p>Conclusion: It’s not just about commands; it’s about understanding isolation. Onward to Day 2!</p> devops docker learninpublic learning
