Have you ever struggled with setting up Docker on a new server?

I remember when I first set up an Ubuntu 24.04 server, and I wanted to use Docker to deploy an application. At first, I found myself a bit overwhelmed. There was a lot of information about Docker installations and configurations, and I wasn’t sure where to start.

I had already heard about Docker’s power and its ability to containerize applications, making them easy to deploy and scale. But the challenge was how to get everything running on a fresh server. Here's how I managed to get Docker set up and deploy a simple Nginx container:

Installing Docker
I started by installing the required dependencies, adding the Docker GPG key, and configuring the official Docker repository for Ubuntu. It was a little tricky at first since I hadn’t done this before, but once I followed the step-by-step commands, everything started to make sense.

Running My First Container
After Docker was installed, I pulled the Nginx image from Docker Hub and ran my first container. For a moment, I was amazed to see my Nginx application running on the server, accessible via port 80. It felt like magic!

Deploying to a Container Registry
The next challenge was pushing the Docker image to a registry. I had to login, tag the image, and push it. It was a great learning experience as I navigated through the registry and used the terminal to manage the image.

It wasn’t without its struggles—especially with Docker’s many settings and configurations. However, once I completed the setup, I felt accomplished, and it opened doors to deploy more complex applications using the same steps.

I also found a particularly helpful docker installation guide on ubuntu that clarified a lot of doubts I had, and it might help you too!

What was your experience? Have you faced any challenges while installing Docker or running containers for the first time? How did you overcome them?
