Integrating Docker with the CI/CD workflow

Let’s see how to integrate Docker with the GitLab CI/CD workflow through a practical example. As a use case, let’s use the example implemented in Chapter 6, Integrating Comet into DevOps, in the Implementing Docker section. The example built an application that tested four different classification models (random forest, decision tree, Gaussian Naive Bayes, and k-nearest neighbors), which classified diamonds cut into two categories (Gold and Silver) based on some input parameters. In addition, the application logged all of the models in Comet.

You can download the full code of the example from the GitHub repository of the book available at the following link: https://github.com/PacktPublishing/Comet-for-Data-Science/tree/main/07.

In that example, we built a Docker image with the code and we ran it. In this section, the idea is to wrap that example in a CI/CD workflow and run it in GitLab. In other words, the idea is to...
