dockerfile-practice

A practice on creating Docker images from Dockerfiles.

1. Create a GitHub repo called dockerfile-practice

2. Add a Dockerfile to it. This Dockerfile should:

• Be based off of one of the Jupyter docker-stacks images (link to Jupyter docker-stacks documentation, link to repo of Jupyter docker-stacks Dockerfiles)

• Add one new R or Python package to the Dockerfile (ensure that you pin the version of the package you add).

• Add a GitHub Actions workflow to automatically build the image, push it to DockerHub, and version the image and GitHub repo when changes are pushed to the Dockerfile (link to a GitHub Actions Workflow you should use for this). Note 1: When setting up the workflow on GitHub Actions, be sure to click “Skip this and setup a workflow yourself”. Note 2: You will need to add your DockerHub username and password (naming them DOCKER_USERNAME and DOCKER_PASSWORD, respectively) as GitHub secrets to this repository for this to work.
