Basics of Docker

In the ever-evolving world of software development, Docker is the game-changer from which we all can benefit.

Docker empowers developers to seamlessly create, package, and deploy applications in lightweight, portable containers. The result? Speedier development, consistent environments, and effortless scaling. Whether you're a developer, a DevOps enthusiast, or simply curious about tech trends, Docker is a must-know tool transforming how we build, ship, and run applications.

Here's a quick 10-step guide to get started with Docker:

1. Install Docker. Download and install Docker from Docker's official website.

2. Verify Installation

docker --version

3. Pull an Image - Fetch a Docker image from a registry using docker pull.

docker pull ubuntu

4. Run a Container - Create and launch a container with docker run.

docker run -it ubuntu

5. Explore Inside - Dive into the container, make changes, and experiment.

docker exec -it [container_name_or_id] /bin/bash

6. List Containers - View all containers.

docker ps -a

7. Stop and Remove - Stop the docker with

docker stop [container_name_or_id]

and remove to manage containers

docker rm [container_name_or_id]

8. Build Custom Images - Craft your own images with Dockerfiles.

docker build -t my-custom-image .

9. Publish and Share - Share your creations on Docker Hub with docker push.

10. Docker Compose (Optional) - Manage multi-container apps effortlessly.

With these steps, you're well on your way to shaping the future of software development!
