    This generates a GitHub Action template that will reproduce your project environment, run the pipeline, and output the results.

    +
    +

    Note: you will still need to configure things on which your environemnt depends, such as API keys, database credentials, etc.

    +
    +
    +

    This also relies on using GitHub runners for your compute and storage, which are both low by design - they are not intended for heavy workloads.

    So, putting things in production in a safe and reliable way starts with recognizing the different pieces we need to recreate our data science environment.

    Then, it becomes a matter of reproducing each of these pieces via code. This part sounds super complicated, and it can be, but a lot of smart people have put a lot of time into making it easier.

    This enables us to create separate environments in which we can do our development and testing before promoting code to production.
