Docker deep dive workbook

Welcome to your Docker deep dive course. You will find exercises and follow up questions in here. The course will work best if we follow it through together so if you can curb your excitement for reading ahead.

Helpful tips & references

• Base images can be found here: https://hub.docker.com/
• Docker build documentation: https://docs.docker.com/reference/cli/docker/build-legacy/
• Docker run documentation: https://docs.docker.com/reference/cli/docker/container/run/
• Docker file syntax reference: https://docs.docker.com/reference/dockerfile/

Building an image For a basic build, adapt this command to match the exercise docker build -t docker-deep-dive/{exercise}/{original|better} -f {filename} .

e.g.

docker build -t docker-deep-dive/ex2/original -f Dockerfile.original .

Listing your built images

docker images
docker images | grep docker-deep-dive/

Running up your images into containers

The basic command would be

docker run --name exercise2 --rm docker-deep-dive/ex2/original

However, different types of dockerfile & image may prompt more complex versions (spoilers!)
