Git is a valuable tool that aids in managing versions of source code and collaborating on software development projects. Integrating Git with Azure for source control can streamline your Data Science Solution workflow, which is a key requirement for passing the DP-100 exam.
Integrating Git with Azure
The first step of integrating Git with Azure is to create a Git repository on your local machine. You do this by initializing an empty Git repository and adding your existing application files to it. You can do this using the Git command line:
git init
git add .
git commit -m “Initial commit”
With your local Git repository set up, you can now create a repository on Azure DevOps for remote collaboration and version control.
Steps to create a repository on Azure DevOps:
- Log in to your Azure DevOps portal.
- Navigate to `Repos > Files` in your Azure DevOps project.
- Click on `Import repository`.
- Choose `Git` as your source type, and paste the URL of your repository.
- Click on `Import` to complete the process.
Working with Git commands on Azure
On Azure, you can now clone the repository to your local machine, create branches to work on different features and merge the branches after your work is done. You should familiarize yourself with the basic Git commands to help you maneuver through the process:
| Action | Git Command |
|---|---|
| Clone a repository | git clone |
| Create a new branch | git checkout -b |
| Switch between branches | git checkout |
| Stage changes for commit | git add . |
| Commit changes to the branch | git commit -m “descriptive message about changes” |
| Push changes to the remote server | git push origin |
With Git integration, Azure supports Continuous Integration/Continuous Deployment (CI/CD). Anytime you push your changes to the remote repository, Azure pipelines can automatically build and deploy your application.
Also remember that Azure supports multiple Git workflows. Depending on the complexity of your project and team preferences, you can choose a workflow that best suits you, such as Centralized Workflow, Feature Branch Workflow, Gitflow Workflow, or Forking Workflow.
Using Azure DevOps, you can track changes in real-time and identify who made what changes and when. This can be particularly useful whilst you work on data science solutions, as it allows an iterative flow of developing, testing, and implementing, allowing you to produce robust models.
Conclusion
Working with Git in Azure creates a reliable, structured and traceable management system for data science projects, and understanding this integration is a vital part of the DP-100 exam curriculum. As long as you make sure to handle conflicts and keep your repositories in check, you’ll be able to leverage Git’s robustness in your projects and collaborations.
