Creating a DVC pipeline

Imagine a simple example of a workflow where a document is printed and then scanned to create a signed PDF document, with DVC managing the dependencies and outputs of each stage.

The print stage depends on printing instructions outlined in print.sh and produces the pages output. The scan stage depends on instructions in scan.sh and pages (output of printer) and produces a signed.pdf output.

Your task is to design a DVC pipeline outlining the workflow using the dvc stage add command. Its syntax is

dvc stage add -n <stage_name> -d <dependency> -o <output> <command>

You can add multiple dependencies and outputs with repeated use of -d and -o flags, respectively.

NOTE: DVC has already been initialized in the exercise setup. There is no need to run dvc init again.

In this chapter, you will explore the essential principles of Continuous Integration/Continuous Delivery (CI/CD) and YAML. You'll grasp the software development life cycle and key terms like build, test, and deploy. Discover the differences between Continuous Integration, Continuous Delivery, and Continuous Deployment. Moreover, you'll investigate the significance of CI/CD in machine learning and experimentation.

Exercise 1: Introduction to Continuous Integration/Continuous Delivery for Machine Learning Exercise 2: Continuous deployment and delivery Exercise 3: Machine learning workflow Exercise 4: Introduction to YAML Exercise 5: YAML syntax Exercise 6: YAML mappings and sequences Exercise 7: Introduction to GitHub Actions Exercise 8: Utility of GitHub Actions Exercise 9: Anatomy of GitHub Actions

Get ready to explore GitHub Actions (GHA), an influential platform for executing CI/CD workflows. Uncover the diverse components of GHA, encompassing events, actions, jobs, steps, runners, and context. Gain insights into crafting workflows that activate upon events like push and pull requests, and tailor runner machines. Dive into hands-on learning as you establish fundamental CI pipelines and grasp the intricacies of the GHA log.
