Docker Learning Path: Extensive Learning

Task 1: Introduction to Containers

Final Evaluation

To understand the basics of containers, we'll create a simple Java program that prints "Hello, Containers!" to the console. We'll then package this program into a Docker image.

Docker Image: extensive-learning-intro-containers

Test Script (test_intro_containers.sh):

If your running a x64 bit Ubuntu or other Linux and find USB transfers hang at the end apply this fix:

echo $((16*1024*1024)) > /proc/sys/vm/dirty_background_bytes
echo $((48*1024*1024)) > /proc/sys/vm/dirty_bytes

I suggest you edit your /etc/rc.local file to make this change persistant across reboots.

sudo nano /etc/rc.local
