CI/CD for Clojure

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

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

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.

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 settingsExemplary pipeline settings

Trigger modes

  • Manually (on click) — recommended for Production
  • On events (automatic) — recommended for Development
  • On schedule (on time interval) — recommended for Staging/Testing
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 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 Clojure app with Leiningen
  • Upload app to server
  • Run db migrations & restart server
  • Send notification to Slack

3.1 Build and test your Clojure app

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

lein test
lein uberjar$$

Run commands consoleRun commands console

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

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 actionsFile transfer actions

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

3.3 Run db migrations & restart server

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

SSH action locationSSH action location

Enter the commands to execute in Run CMDs and configure authentication details in the Target tab:

Application restart commandApplication restart command

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 actionsNotification actions

If you add this action to Actions run on failure, Buddy will only send a message if something goes wrong with your build or deployment. On failure notificationOn 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! 🔥

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.
