Infrastructure basics for data work

The ground a data project stands on: the command line, how a name finds a server, packaging an app in a container, where files and databases live, keeping secrets out of code, backups you have tested and a cloud bill you control.

Outcomes

What you will be able to do

  • Look at, count, filter, group and sum a CSV file with head, wc, cut, sort, uniq, grep and awk, each with the output it produced.

  • Use a slim base image, install dependencies before copying code so builds are cached, run as a normal user, keep secrets out of the image and ignore what does not belong.

  • Credentials committed to a repository are found fast and abused faster. How to keep them out, find the ones already there, and what to do the moment one leaks.

  • A backup you have never restored is a hope. Twelve checks that turn backups into a recovery you can rely on, with the reason behind each.

Questions

Before you start

Who is this for?
The ground a data project stands on: the command line, how a name finds a server, packaging an app in a container, where files and databases live, keeping secrets out of code, backups you have tested and a cloud bill you control. It is written for beginner readers.
How long does it take?
About 15 minutes of reading and doing across 4 lessons. Each lesson shows its own time, so you can do one at a sitting.
Do I need an account?
No. Everything here is free to read. An account is only needed to ask or answer a question in the community.
What if I get stuck on a lesson?
Ask in the community: say which lesson, what you tried and what happened. Every lesson also shows when it was last verified.
