I’ve known about Docker for 2–3 years but never fully understood its popularity and necessity until a month ago I decided to build a home server to deploy my own applications.

Without Docker, deploying an app would require installing Node, nvm, git, VS Code, PM2, and NGINX on my Linux server. Managing multiple apps with different Node versions and configurations would be complex.

Docker containers allow me to deploy my app without installing packages on the host machine, keeping things organized and secure in their own containerized environments. Configurations can be changed without affecting the host system. This also solves issues like Python environment conflicts.

Docker is not an easy concept to understand. Building a home server revealed Docker’s true power in simplifying application deployment and solving real-world problems.. For me its benefits only became clear when facing these challenges firsthand.

And that’s all the experiences I’d love to share.
