DevOps-Containerization

Docker Installation Verification & Nginx Deployment (Windows)

Overview

This practical demonstrates verification of Docker Desktop installation, testing Docker Engine connectivity through CLI and REST API, and deploying a production-ready Nginx container. It focuses on understanding container lifecycle management and real-world DevOps deployment workflow.

Environment Details

Operating System: Windows 11
Docker Desktop
Docker Engine
Command Prompt (CMD)
Base Image: Nginx (latest)

Step 1: Verify Docker Installation

docker --version
docker version
docker info

Step 2: List Containers

docker ps
docker ps -a

Step 3: Test Docker Engine REST API

(Ensure Docker Desktop setting: “Expose daemon on tcp://localhost:2375 without TLS” is enabled)

curl http://localhost:2375/_ping
curl http://localhost:2375/version

Step 4: List Containers via Docker REST API

curl http://localhost:2375/v1.43/containers/json
curl "http://localhost:2375/v1.43/containers/json?all=true"

Step 5: Pull Nginx Image

docker pull nginx
docker images

Step 6: Create and Run Nginx Container

docker create --name mynginx -p 8080:80 nginx
docker start mynginx
docker ps

Access in browser:

http://localhost:8080

Step 7: Inspect Container

docker inspect mynginx

Step 8: Stop and Remove Container

docker stop mynginx
docker rm mynginx
docker ps -a

Container Lifecycle Demonstrated

Pull → Create → Start → Inspect → Stop → Remove

Result

Docker installation successfully verified.
Docker Engine connectivity confirmed via CLI and REST API.
REST API communication validated.
Nginx container deployed successfully.
Container lifecycle operations performed successfully.

Conclusion

This practical strengthened understanding of Docker architecture, daemon communication, REST API interaction, and production-ready container deployment using Nginx. It demonstrates core DevOps container workflow implementation in a Windows-based environment.
