1. Feature Experimentation Workflow with GitHub Branches.


    Creating a feature experimentation workflow involves using a version control system like GitHub to isolate changes in separate branches. The typical process involves creating a feature branch off the main branch, making changes in this new branch, and then merging the changes back into the main branch upon completion.

    To automate this process with Pulumi and GitHub, we can use Pulumi's GitHub provider to create and manage GitHub branches programmatically.

    Below you will find a Pulumi program in Python that demonstrates how to create a new feature branch in a GitHub repository. We will use the pulumi_github package to interact with GitHub:

    import pulumi import pulumi_github as github # Replace the following with your GitHub repository details repository_name = 'example-repo' # GitHub repository where you want to create the branch source_branch_name = 'main' # The name of the branch you want to branch from feature_branch_name = 'feature-x' # The name of the new feature branch # Fetch the repository using the GitHub provider repo = github.Repository.get('repository', repository_name) # Create a new branch for the feature from the source branch feature_branch = github.Branch('feature-branch', repository=repo.name, branch=feature_branch_name, source_branch=source_branch_name, ) pulumi.export('feature_branch_name', feature_branch.branch)

    Here's what this Pulumi program does:

    1. It defines some important variables including the name of the GitHub repository (repository_name), the source branch name (source_branch_name), and the feature branch name (feature_branch_name) that we want to create for our feature.
    2. It obtains a reference to the repository on GitHub using Pulumi's get function.
    3. It creates a new Branch resource using Pulumi's GitHub provider. This branch will be based on the source_branch_name and will be named feature_branch_name.

    This program will manage the feature branch as a real infrastructure. You will be able to create, update, and delete it programmatically just like you would with any cloud resource managed by Pulumi.

    Running the Program

    To run this program, you'll need to have Pulumi installed and configured with your GitHub access token. You'll also need the pulumi_github provider installed in your Python environment. With Pulumi set up, you can simply apply this Pulumi program to create the feature branch in your GitHub repository.

    You can view the GitHub Branch documentation for additional options you may use with the Branch resource for different scenarios, such as branch protection rules or branch deletion constraints.

    Remember, with Pulumi, you're not just automating infrastructure on cloud providers, but also managing the entire software development lifecycle, including interactions with version control systems like GitHub.
