Mastering DevOps Batch Lecture 13 Docker Storage & Networking Volumes, Bind Mount, tmpfs, Bridge

Welcome to Mastering DevOps Batch – Lecture 13 🚀 In this lecture, we explored Docker Storage and Networking concepts with hands-on practical examples. You will learn how Docker manages container storage and how containers communicate with each other using Docker networks. This is a very important topic for real DevOps environments, especially when running applications like databases, microservices, and distributed systems. 📦 Docker Storage Topics Covered Non-Persistent Storage ✔ Default container writable layer ✔ Data loss when container is deleted ✔ tmpfs storage (memory-based storage) Commands demonstrated: docker container run -it --name mycon -d ubuntu docker exec -it mycon mkdir /testdir docker exec -it mycon touch /testdir/test.java docker restart mycon docker rm -f mycon tmpfs example: docker container run -it --name mycon --mount type=tmpfs,destination=/mydir -d ubuntu docker exec -it mycon touch /mydir/temp.java docker restart mycon 💾 Persistent Storage Docker Volumes We learned: Creating volumes Volume storage location Attaching volumes to containers Sharing volumes between containers Read-only volumes Commands demonstrated: docker volume create demo-vol docker volume ls docker container run -it --name c2 --mount source=demo-vol,destination=/demo -d ubuntu docker exec -it c2 touch /demo/demo.java docker inspect c2 docker rm -f c2 Volume path in Linux: /var/lib/docker/volumes/ Bind Mount Bind mounts connect a host directory to a container directory. Example: mkdir mydir docker container run -it --name c1 -v /home/raman/mydir:/demo -d ubuntu docker exec -it c1 touch /demo/demo.java Bind mount using --mount: docker container run -it --name c1 --mount type=bind,source=/home/raman/mydir/,destination=/demo1 -d ubuntu 🌐 Docker Networking Concepts We also covered Docker Networking fundamentals. Docker provides multiple network types: ✔ Bridge (default) ✔ Host ✔ None ✔ Custom bridge networks Default Bridge Network Containers automatically connect to the bridge network. docker network ls docker run -it --name c1 -d centos:7 docker inspect c1 docker exec -it c1 ip a Custom Docker Network Creating a custom bridge network: docker network create -d bridge webnetwork --subnet 192.168.0.0/16 --gateway 192.168.0.1 docker network inspect webnetwork Running containers on custom network: docker container run -it --name web -p 80:80 --network webnetwork -d ramansharma95/webapp docker container run -it --name db --network webnetwork -d ramansharma95/mysql Host Network Container shares host network stack. docker container run -it --name web --network host -d nginx None Network Container runs without network connectivity. docker container run -it --name n1 --network none -d centos:7 Attach network later: docker network connect bridge n1 🎯 What You Will Learn ✔ Docker storage architecture ✔ Persistent vs Non-Persistent storage ✔ Docker volumes ✔ Bind mounts ✔ tmpfs storage ✔ Docker bridge network ✔ Custom networks ✔ Host and none networks ✔ Container communication 🚀 Why This Lecture is Important In real DevOps environments we use: Docker volumes for databases Bind mounts for development Custom networks for microservices Understanding Docker storage and networking is critical for Kubernetes and production deployments. 🏷️ YouTube Tags (Comma Separated) docker storage tutorial, docker volumes tutorial, docker persistent storage, docker non persistent storage, docker tmpfs example, docker bind mount tutorial, docker volume create example, docker storage devops, docker networking tutorial, docker bridge network explained, docker host network tutorial, docker none network example, docker custom network tutorial, docker container networking, docker volumes vs bind mount, docker devops course, mastering devops batch, docker practical tutorial, docker interview questions, docker for beginners, docker container storage, docker network create bridge, docker networking devops
