Challenge
Get Started in the Lab Environment
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!
-
Challenge
Enable Docker Engine
The Docker Engine package is already installed! Now, it's time for you to verify it's working, perform post-installation setup, and explore the default configuration and process architecture.
-
Challenge
Create a Docker Context over SSH
Now that you have local access mastered--on the primary machine--you will set up access to a remote machine's Docker Engine daemon. And you'll set up what is known as a Docker context to connect over SSH to the remote daemon's unix socket.
-
Challenge
Secure Access to the API
SSH is definitely convenient for secure remote access to the Docker daemon. You can also open up a TCP port to access the HTTP API. And then secure that port with Mutual TLS (mTLS).
-
Challenge
Explore containerd
Now that you have secure access to the daemon, you will dissect it to understand the role of containerd in managing containers and images, and how it uses runc, an OCI compliant runtime.
-
Challenge
Enable Live Restore
It's time to toggle a feature called Live Restore. You will study what happens to containers when the Docker daemon is stopped and later restarted. You'll do this with and without Live Restore enabled.

The Last Challenge
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.
Real skill practice before real-world application
Hands-on Labs are real environments created by industry experts to help you learn. These environments help you gain knowledge and experience, practice without compromising your system, test without risk, destroy without fear, and let you learn from your mistakes. Hands-on Labs: practice your skills before delivering in the real world.
Learn by doing
Engage hands-on with the tools and technologies you’re learning. You pick the skill, we provide the credentials and environment.
Follow your guide
All labs have detailed instructions and objectives, guiding you through the learning process and ensuring you understand every step.
Turn time into mastery
On average, you retain 75% more of your learning if you take time to practice. Hands-on labs set you up for success to make those skills stick.
