CI/CD for Scala

Buddy lets you create delivery pipelines that will build, test and deploy your Scala application on a single push to branch. The pipelines consist of actions that you can configure depending on your needs. Example of a Scala 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 Scala application
  • Upload code to server together with compiled assets (FTP/SFTP/Rsync & more)
  • Run db migrations & restart server
  • Send notification to Slack

3.1 Build and test your Scala app

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

sbt compile

Default build commands for scala

3.2 Deploy application to server

The compiled 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: Configuring the SFTP action

3.3 Run DB migrations & restart server

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

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

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.
