Why should we care about docker?

• Local experiments
• Integration tests (CI/CD)
• Reproducibility
• Running pipelines on the cloud (AWS Batch, Kubernetes jobs)
• Spark
• Serverless (AWS Lambda, Google functions)

1. Go to course repo

1. Open Terminal, test docker to see if it’s working

docker run hello-world

1. Run an Ubuntu container

docker run -it ubuntu bash

// run - run this image
// -it - do it in interactive mode, i.e. terminal
// ubuntu - name of the image it will run
// bash - parameter that we want to execute in this image

docker run -it --entrypoint=bash python:3.9
