Docker Basics — Building and Deploying to EC2

Fri, 08 May 2026 00:00:00 +0000

Docker packages an application and everything it needs into a container. Same image, identical behaviour on any machine. This post covers building a custom nginx image and deploying it to AWS EC2.

Podman on Fedora

Docker doesn’t run inside a Toolbox container — kernel module restrictions. Podman is Docker-compatible and works natively on Fedora:

echo 'alias docker=podman' >> ~/.bashrc
source ~/.bashrc

Same commands, no workarounds needed from this point.

Building a Custom Image

docker-nginx/
├── Dockerfile
└── index.html

FROM docker.io/library/nginx:latest
COPY index.html /usr/share/nginx/html/
EXPOSE 80

docker build -t my-nginx:v1.0 .
docker run -d -p 8080:80 --name my-nginx my-nginx:v1.0

Open http://localhost:8080 — custom HTML served via nginx inside a container.
