Cloud Source Repositories Tutorial
Introduction
Cloud Source Repositories (CSR) is a fully-featured, scalable, and private Git repository hosted on Google Cloud. It allows you to collaborate on source code and manage your repositories with ease. This tutorial will guide you through the process of setting up and using Cloud Source Repositories from start to finish.
Prerequisites
Before you begin, ensure you have the following:
- A Google Cloud account
- Google Cloud SDK installed
- Git installed on your local machine
Setting Up the Environment
1. Install Google Cloud SDK
If you haven't already installed the Google Cloud SDK, you can download and install it from the official Google Cloud SDK installation guide.
After installation, initialize the SDK:
gcloud init
This command will guide you through the initial setup of the SDK, including authentication and project selection.
2. Authenticate with Google Cloud
gcloud auth login
This command will open a browser window for you to authenticate with your Google account.
Creating a Cloud Source Repository
1. Create a New Repository
To create a new repository, use the following command:
gcloud source repos create REPOSITORY_NAME
Replace REPOSITORY_NAME with the desired name of your repository.
2. Clone the Repository
Once created, clone the repository to your local machine:
gcloud source repos clone REPOSITORY_NAME --project=PROJECT_ID
Replace REPOSITORY_NAME with your repository name and PROJECT_ID with your Google Cloud project ID.
Working with the Repository
After cloning the repository, you can start working with it just like any other Git repository.
1. Add Files
Create a new file in the repository directory:
echo "Hello, Cloud Source Repositories!" > hello.txt
2. Commit Changes
Stage and commit your changes:
git add hello.txt
git commit -m "Add hello.txt"
3. Push Changes
Push the changes to the Cloud Source Repository:
git push origin master
Managing Branches
1. Create a New Branch
To create and switch to a new branch:
git checkout -b feature-branch
2. Merge Branches
Once you have made changes in the new branch, you can merge it back into the master branch:
git checkout master
git merge feature-branch
3. Delete a Branch
After merging, you can delete the feature branch:
git branch -d feature-branch
Integrating with Other Google Cloud Services
Cloud Source Repositories can be integrated with other Google Cloud services like Cloud Build for CI/CD, Stackdriver for monitoring, and more. Here’s a basic example of setting up a trigger to build your code on every push using Cloud Build.
1. Create a Cloud Build Trigger
Navigate to the Cloud Build section in the Google Cloud Console and create a new trigger. Set the trigger to activate on changes to your Cloud Source Repository.
2. Define Build Configuration
Create a cloudbuild.yaml file in your repository to define the build steps:
steps:
- name: 'gcr.io/cloud-builders/gcloud'
args: ['app', 'deploy']
3. Push Changes and Trigger Build
Push your changes to the repository, and Cloud Build will automatically trigger the build process as defined in your cloudbuild.yaml.
Conclusion
Cloud Source Repositories offer a powerful, scalable, and integrated solution for managing your source code on Google Cloud. By following this tutorial, you should now have a solid understanding of how to set up and use Cloud Source Repositories effectively.
