Build a Containerized Application with Docker

Here are the initial instructions and explanation of the lab environment. Read this while your environment is busy creating itself from nothing. Yes, this violates physics; we know. How fun!

To start, you will create and manage a Docker container. You will begin with a base image, copy application files, build a Docker image with a Dockerfile, and run it in a container with port mapping. Afterward, you’ll test the application by accessing it through HTTP, ensuring proper functionality. The challenge will also cover stopping and removing containers once testing is complete.

In this challenge, you will learn how to manage Docker containers and monitor their resources easily. You will create, run, and use Ubuntu and NGINX containers, and will also practice using commands to check, start, stop, restart, and delete containers. You will solve problems using logs, and track container performance in real-time with Docker stats.

To finish things off, you will learn to optimize containerized applications by reducing Docker image size, selecting lightweight base images, and ensuring efficient workflows. You will explore techniques to tag Docker images with versioning for reusability, and enhance collaboration by following best practices in container development.

Welcome to the final challenge! This is your last chance to experiment in the environment. Clicking Finish Lab will end this little world that flittered into existence just for you.
