The objective of this track is to learn how to inject data dynamically at test time using just-in-time data.

You'll emulate user input that is typically added in a track's challenge manually using a solve script that will be verified later in a check script.

In this first challenge, you're going to get a random word from an online resource and then assign that random word to an environment variable that you'll persist in the /root/.bashrc file. Saving the environment variable to the /root/.bashrc file will makes its value available later on.

The online resource you'll use to get a random word is an API published by https://wordnik.com. You'll need to register to the site and get an API key in order to have the website provide a random word. You'll add the API to the URL that you'll call using a curl command. The command you'll use to get the random word is:

SECRET_MESSAGE=$(curl -s 'https://api.wordnik.com/v4/words.json/randomWord?api_key=<YOUR_API_KEY> | jq -r '.word')

How Many CNCF Graduated Project uses gRPC?

Of the 11 graduated projects listed below 9 use gRPC

Methodology

The method used to determine if a project uses gRPC is to run the cloc line code analysis tool on the each of the code repository in GitHub of each of the projects graduated by the CNCF as listed here as of September 28, 2020. The only proejct that was omitted is TUF because it is a specification only.

cloc analyzes all the code in the repo and organizes the results according to file type. Also, it inspects each file discovered and analyzes the file and reports the number lines in the file, as blank, comment and active.

Cloc is invoked using the following command that executes a shell script.
