Docker-Image-Container-02

This repository documents the completion of the DevOps challenge :

“Build your first Docker image, run it, push it to Docker Hub, and share it.”

The objective is to demonstrate a complete end-to-end Docker workflow and validate foundational containerization skills.

Overview

The challenge consists of the following steps:

• Develop a minimal application to serve as the basis for the Docker image.
• Create a Dockerfile that defines the build instructions.
• Build the Docker image locally using the Docker CLI.
• Run and test the container to verify expected behavior.
• Publish the image to Docker Hub under a public repository.
• Share the Docker Hub link and repository as a final deliverable.

This repository contains all files used during the process.

what i learned :

FROM nginx:alpine What it does: - Declares the base image for your image. You’re saying: “Start from the official nginx image, specifically the small alpine variant.” - nginx:alpine already contains: - the NGINX web server executable, - a configuration (/etc/nginx/nginx.conf) with defaults, - a default document root: /usr/share/nginx/html. Why use it : - You don’t need to install NGINX yourself — it’s preinstalled in the base image. - alpine is a small Linux distribution, so the image is compact. COPY site/ /usr/share/nginx/html (i'll finish the rest some other time)
