Docker Learning Resources

Here is a collection of resources that are useful for learning about docker, from the ground up.

What are Containers?

• guide from docker's website
• deep dive on Linux kernel tech that underpins containers from Red Hat

Docker CLI

• overview of docker commands
• docker's docs

Docker Experiments

Quick demos that show what you can do with the docker CLI alone

Startup a new mysql server locally; see "How to use this image" section.

Run a redis server locally & attach to it with just one line:

docker run -it --rm redis redis-cli -h some-redis

Print out the resolv.conf for Ubuntu:latest

docker run ubuntu:latest cat /etc/resolv.conf

Run a local python script inside an Alpine container. This works even if python is not installed on your machine!

echo "print('hello, world!')" > main.py
docker run -v $(pwd)/main.py:/main.py python:3-alpine python3 main.py
