Docker Complete Course for Beginners in Tamil – From Basics

Explore Docker containers and their relation to virtual machines in a Docker environment. Get started with the basics of Docker containers.

Run your application inside a virtual machine by configuring a Linux guest, allocating 8 gb of ram and sufficient file system space, and starting the vm for testing.

Start the docker engine, build container images with the CLI, and manage containers using the terminal and docker desktop, including viewing container lists and folder structures.

Explore how a Docker container works and how the Docker run command enables containers to communicate.

Learn how to run a docker container with the docker run command, use the -p flag for port mapping, name the container, and reference the image to create and start.

Explore how ports enable applications to run and how to specify port numbers such as 8080, 8081, 80, and 8088 for a calculator or calendar app.

Practice port concepts with a calculator application running on port 5000, access it via its URL, and compare different ports such as 88 and 8080 used by Jenkins.

Learn how to map host ports to container ports with Docker run, using a calculator app example and ports like 8080 and 8081.

Explore docker storage volumes and Docker volume concepts, and learn how to solve common Docker storage problems.

Understand how docker volumes preserve container storage, store files in a local system folder, and manage history files for a calculator app within a volume.

Create and manage Docker volumes with simple commands, including docker volume create, docker volume ls, and docker volume inspect, and map volumes to folders in the local system.

Demonstrate the real-time flow of Docker volumes as a container manages data in the data folder and folder volume, including mounting, deleting, and accessing history.

Explore bind mounts in Docker, compare mount differences, and understand the advantages of mounting data in containers.

Fix the problem with bind mounts by connecting a Docker container to a local folder or volume on your machine, enabling saving and managing files from the container.

Master bind mounts in Docker by using the -v option to link a local folder to a container folder, enabling data sharing between host and container.

Explore how a Dockerfile defines the build for a calculator application, creates a Docker image and container, and includes JavaScript code inside the application.

Choose an operating system for your Docker image, examine base images like Ubuntu, and compare container file system structures for calculator and SQL containers.

Define the base image using the from command, choosing ubuntu as the image name and version, and reference Docker Hub and the Ubuntu official page.

Create a work directory inside the app folder and copy project files from the local system into the image using the current directory.

Define the container startup command with CMD and run node app.js inside the container to launch the application.

Explore the full flow from a dockerfile to a container by working with a base image, downloading a directory, creating files, copying node modules, and running the image with CMD.
