Every DevOps journey has a first milestone!
(Mine just happened with Docker)
I’m happy to share that I successfully deployed my first application inside a Docker container.
I have officially joined my team as a volunteer DevOps engineer.
We are currently building an app.
During our last call, we agreed to use Kubernetes for deploying the app.
While Kubernetes is still new to me, I decided not to wait until that stage of training. With the help of a friend, I started with Docker.
Docker is the foundation for Kubernetes.
After a solid 2-hour learning session, I had my first application project up and running locally inside a container.
Project Highlights:
=============
1)Installed Git and set up a new repository on GitHub
2) Cloned the repo locally using VS Code
3) Defined application dependencies
4) Built a Docker image from the project
5) Deployed and ran the image in a Docker container
Key Strengths of this Project:
===================
a) Containerization – Application packaged into an isolated and reproducible Docker image
b) Portability – The app can now run the same way across any environment with Docker
c) Hands-on CI/CD foundation – This workflow is a stepping stone towards automated builds and Kubernetes deployment
Challenges & Lessons Learned
===================
- GitHub Repo Cloning Issues:
Initially, cloning failed because Git wasn’t installed locally. After installing, VS Code still didn’t recognize it until I restarted the IDE. I later discovered the cloned repo was hidden inside my user folder.
- Docker Desktop Not Opening:
At first, the Docker app refused to start. I had to uninstall, reinstall, and reboot my system for it to work properly.
- Folder Visibility & Workflow Navigation:
Locating project folders from VS Code helped me better understand how repositories and local environments interact.
Why This Project Matters
===================
This may look small to seasoned DevOps professionals, but for me, it’s a big milestone. I not only learned how to containerize an application, but also developed troubleshooting skills that are essential in DevOps.
By doing and documenting this, I’ve gained confidence and understood that every challenge is an opportunity to strengthen my understanding.
This project is just the start, and I’m excited to continue building on it as I move towards Kubernetes and CI/CD automation.
