Day 17 Task: Crafting a Dockerized Web Application 🐳✨

Hello, DevOps dynamos! Today's #90daysofdevops challenge was exhilarating! I rolled up my sleeves and got my hands Docker-deep in containerizing a web application. 🌐

The Magic of Dockerfile 📜

I kicked off my day by crafting a Dockerfile, the blueprint for building Docker images. It's like a recipe, outlining each step to package my web app into a container.

Here's a sneak peek into what my Dockerfile adventure entailed:

Writing the Dockerfile 🖋️

• Started with a base image: For my Django app, python:3.8-slim was a perfect start.

• Crafted the steps:

  • Set a working directory: WORKDIR /app

  • Copied the project files into the image: COPY . /app

  • Installed the dependencies: RUN pip install -r requirements.txt

  • Exposed the port the app runs on: EXPOSE 8000

  • Defined the command to start the server: CMD ["python", "manage.py", "runserver", "0.0.0.0:8000"]

    

Building the Image 🏗️

• Ran docker build -t my-django-app . to transform my Dockerfile into a runnable image.

• Watched the build process closely, ensuring each step was executed without hiccups.

  

Running the Container 🚀

• Used docker run -d -p 8000:8000 my-django-app to breathe life into my image, creating a container.

• The -d flag meant it ran in the background, and -p connected the container port to my host.

  

Ensuring Everything's Shipshape 🖥️

• Navigated to http://localhost:8000 on my browser and was greeted by my Django app's welcome page.

• It was alive! The application responded to my requests, just as it would in its natural server habitat.

  

Docking the Image on Docker Hub 📤

• I tagged my image with docker tag my-django-app username/my-django-app:latest.

• Pushed it to Docker Hub with docker push username/my-django-app:latest.

• Now, my container was not just on my machine but out in the world for others to pull and use!

  

Wrapping Up the Day's Voyage 🗺️

Today, Docker demystified, I feel like a true DevOps Engineer, ready to containerize the digital world—one Dockerfile at a time. Stay tuned for more DevOps adventures and mishaps! #Day17 #DevOpsProject #DockerizeAllTheThings #Containerization #DockerHub 🐳🚀
