Experiment 2

Docker Installation, Configuration, and Running Images

Objective

1. Pull Docker images
2. Run containers
3. Manage container lifecycle

Step 1: Pull Docker Image

Command used:
docker pull nginx

Step 2: Run Container with Port Mapping

Command used:
docker run -d -p 8080:80 nginx

This command runs the NGINX container in detached mode and maps port 8080 of the host machine to port 80 of the container.

Step 3: Verify Running Containers

Command used:
docker ps

This command displays all currently running containers.

Step 4: Stop and Remove Container

Commands used:
docker stop docker rm

These commands stop the running container and remove it from the system.

Step 5: Remove Docker Image

Command used:
docker rmi nginx

This command removes the NGINX image from the local Docker repository.

Conclusion

In this experiment, Docker was successfully used to pull images, run containers, and manage their lifecycle.
The NGINX image was downloaded and executed with proper port mapping to allow access through the host system.
Running containers were verified using Docker commands.
Containers were safely stopped and removed after use.
Finally, the Docker image was deleted to free system resources.
This experiment demonstrates the basic working of Docker and its importance in container-based application deployment.
