Docker Overview
Docker is a platform that enables developers to package applications into containers—standardized executable components combining application source code with the operating system (OS) libraries and dependencies required to run that code in any environment. As a recent IT graduate, I have gained hands-on experience with Docker through various projects and coursework, understanding its significance in modern software development and deployment.
Key Features of Docker
Containerization
Isolating applications for consistency across environments.
Portability
Running applications on any system with Docker installed.
Scalability
Easily scaling applications by managing containers.
Version Control
Managing different versions of applications efficiently.

Personal Portfolio Website
Deployed a personal portfolio website using Docker containers, ensuring easy setup and scalability. Utilized Docker Compose to manage multiple services like web server and database.
Microservices Architecture
Experimented with Docker to set up and run popular self-hosted applications like Immich (for photo management) and WireGuard (for secure VPN). Used Docker containers to keep each tool separate and manageable, with Docker Compose to start and connect them easily. Managed everything through Portainer, which helped me monitor and adjust the containers on my system without much hassle.
CI/CD Pipeline
Learned to use Docker and Portainer to deploy and manage applications like Immich and WireGuard on my own setup. Used Jenkins to automate the process of updating these Docker containers whenever I made changes, making it simpler to test and roll out updates to my self-hosted environment without manual effort.

Impact of Using Docker
Through my projects, I have experienced firsthand how Docker simplifies development and deployment processes. It has significantly reduced setup time for development environments and ensured consistency between development and production setups. Additionally, working with Docker has enhanced my understanding of containerization and its role in modern DevOps practices.
Future Plans with Docker
As I embark on my professional journey, I am eager to deepen my knowledge of Docker and containerization technologies. I plan to explore advanced topics such as container security, orchestration with Kubernetes, and integrating Docker into larger DevOps workflows. Additionally, I aim to contribute to open-source projects that leverage Docker to enhance my practical skills.
