Managing containers with docker run, ps, stop, and rm
Interactive vs detached mode
By the end of this lesson, you will be able to launch, monitor, and stop containers confidently.
Dockerfiles & Custom Images8:59
In this lesson, we will learn how to create custom Docker images using Dockerfiles. This is a key skill for packaging your own applications.
We will cover:
Writing a basic Dockerfile
Building an image with docker build
Tagging and versioning images
By the end of this lesson, you will be able to create and manage your own Docker images.

Requirements

No previous Docker experience is required.
A computer capable of running Docker Desktop.
Basic command-line knowledge is helpful but not required.
An internet connection for downloading Docker and Docker images.

Description

Docker is one of the most important tools used in modern software development, but before working with Docker in real-world projects, it is important to understand the fundamentals.

This course provides a beginner-friendly introduction to Docker and containerization, with examples and explanations aimed at Python developers.

We will start by understanding what Docker is and why containers are useful. Then, we will install Docker and explore the architecture behind it.

After that, we will learn what Docker images are, how they are created and stored, and how containers are created from images.

Finally, we will work with Docker containers and learn the basic commands needed to create, start, stop, inspect, and remove them.

The goal of this course is to give you a solid foundation in Docker before moving on to more advanced topics.
