Docker Crash Course: Learn from Experience (for Beginners)

Understanding the core concepts will make you a better Docker practitioner. What is a container? How is it different from a VM? And how does Docker come into play?

Learn how to install the Docker Engine

Learn how to install Docker Compose

A sneak peek at the Docker client and some of the commands we'll be using the most throughout the course. Learn how to get the usage details for each Docker command

What is a Docker Image? What about a Dockerfile? And finally, how to store and share Docker Images via a Docker Registry?

Revisit the Docker CLI to get help on the available Docker commands for image management. We'll also navigate through some of the commands and options you will learn during this section, like "build", "inspect", "push", "pull", "ls", "rm" and "tag".

Learn how to pull (download) a Docker Image from Docker Hub

A super quick overview of the Dockerfile syntax and the Docker build command

Learn how to build Docker Images from a Dockerfile, starting from the docs and trying out the first four essential Dockerfile instructions: FROM, RUN, CMD and ENTRYPOINT

Learn how to move your application artifacts from your build environment into a Docker Image, using the ADD and COPY instructions.

Third and final lesson on how to write Dockerfiles. In this one you will learn how to use the instructions EXPOSE, ENV and WORKDIR, for marking network ports, setting environment variables and defining a working directory, respectively

Learn how to push your own Docker Images into an online public Docker Registry (Docker Hub in this lesson)

A final consolidation on "What is a Docker Container?". What is the relationship between a Docker Image and a Docker Container? What does a Docker Container look like from an Operating System perspective?

Have a sneak peek at the Docker Containers CLI, to get to know the container commands we'll be using in this section

Get started with Docker Containers. Learn how to run a container and how to attach, remove and interactively connect to one.

Let's deploy a simple web server in a container. With it, you'll understand how important port mappings are and how to define them. You'll also learn how to share your own files with the container, via bind mounts.

Learn how to pass environment variables to a containers and how to define restart policies such that Docker takes care of automatically restarting your container, based on a predefined condition.

Learn how to start, stop, restart and remove a container - the 4 most common lifecycle management actions you'll do during the container's lifetime

Learn how to thoroughly inspect a container. First by looking at its output, then by checking its low-level information, and finally, by getting inside the running container and debugging it manually.

Finally, the last essential functionality is about copying files and directories, to and from a running container.

A general overview of the Docker Volume, and how it is different from a bind mount.

Starting from the usual bind mount, learn about Docker Volumes, how to manage them, and how are they different from a regular bind mount

For our last Docker object, we have networks. Learn about Docker Network drivers and how these impact your containers' behavior with respect to networking.

Learn how to manage and use bridge and host networks

Let's have a quick look back at everything we've learned in this course, and summarize the key parts.

A special lesson just to get you started with multi-container Docker applications, using Docker Compose. This is a super compressed lesson, just to tease your curiosity about the tool.

For this final lesson, I'm gonna give you some useful references...things you should bookmark in your favorites, that will come handy at some point in the future, be it documentation or test environments for you to practice.
