CI/CD for Python

📚 Learn more about Python action features, integrations and alternatives.

Buddy lets you create delivery pipelines that will build, test and deploy your Python application on a single push to branch. The pipelines consist of actions that you can configure depending on your needs. Example Python pipeline

Configuration is very easy and takes only a couple of minutes.

1. Select your Git repository

Buddy supports all popular Git hosting providers, including GitHub, Bitbucket and GitLab. You can also use your own private Git server, or host code directly on Buddy. Supported Git providers

2. Add a new delivery pipeline

Enter the pipeline's name, select the trigger mode, and define the branch from which Buddy will fetch your code: Exemplary pipeline settings

Branch assignment — this is the branch from which Buddy will deploy. If you set the trigger mode to On push, Buddy will execute the pipeline upon every push to that branch.

Trigger modes

  • Manual (on click) — recommended for Production
  • On push (automatic) — recommended for Development
  • Recurrently (on time interval) — recommended for Staging/Testing

3. Add actions

Buddy lets you choose from dozens of predefined actions. In this example, we'll add 4 actions that will perform the following tasks:

  • Build and test your Python application
  • Upload application to server
  • Run db migrations & restart application
  • Send notification to Slack

3.1 Build and test your Python app

Look up and click the Python action to configure it. Here you can choose the version of Python and determine the commands to execute. The default commands are:

pip install -r requirements.txt
nosetests

Default Python build commands

If your tests require a database to run, you can attach it in the Services tab: Services tab

There is also a dedicated action for Django projects.

3.2 Deploy application to server

The built application needs to be uploaded to the server. Head to the Transfer section and select your action (SFTP in our case): File transfer actions

When adding the action you can choose what and where should be uploaded: SFTP action configuration

3.3 Run db migrations & restart application

Once the app is deployed, you can run additional commands on your server with the SSH action: SSH action selection

Enter the commands to execute and configure authentication details: Restarting the application

3.4 Send notification to Slack

You can configure Buddy to send your team a message after the deployment. In this example we'll use Slack: Notification actions

If you add this action to 'Actions run on failure', Buddy will only send a message if something went wrong with your build or deployment.

4. Summary

Congratulations! You have just automated your entire delivery process. Make a push to the selected branch and watch Buddy fetch, build, and deploy your project. With Continuous Delivery applied, you can now focus on what's really important: developing awesome apps! 🔥

Bear in mind that this article is only a brief example of what Buddy can do. You can create additional pipelines for staging and production environments, integrate with your favorite services (AWS, Google, Azure), trigger tests on pull requests, build Docker images and push them to the registry—the possibilities are unlimited.
