CI/CD for Scala

With Buddy, you can create a pipeline that builds, tests, and deploys Scala applications on a push to Git. The configuration is super simple and takes 10 to 15 minutes.

Scala pipeline example

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:

Adding a new pipeline

Success

Event-based triggers allow you to run pipelines whenever a push is made to any branch in the repository, or whenever a branch, tag or a pull request is created or deleted. On event pipeline trigger mode

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 Scala on the action list to add it to the pipeline:

Action list

Upon adding the action, you will be asked to select the version of Scala and JDK:

Selecting Scala & JDK version

The Run tab lets you determine the commands to execute. The default command is:

bashsbt compile$

Default build command for Scala

You can install missing packages & tools in the runtime environment tab:

Packages & Tools

Tip

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

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:

SFTP action configuration

3.3 Run DB migrations & restart server

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 in Run CMDs and configure authentication details in the Target tab:

SSH action selection

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

Hint

If you add this action in the On Failure tab, Buddy will only send the message if something goes wrong with your build or deployment. On failure notification

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! 🔥
