CI/CD for Haskell

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

Image loading...Go 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.

Image loading...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:

Image loading...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. Image loading...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 Haskell application
• Upload code to server
• Run db migrations & restart server
• Send notification to Slack

3.1 Build and test your Haskell app

Look up and click Haskell on the action list to add it to the pipeline:

Image loading...Action list

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

bashcabal update
cabal install --only-dependencies --enable-tests
cabal configure --enable-tests
cabal build
cabal test$$$$$

3.1.2 Haskell version

You can change the version of Haskell and install missing packages & tools in the runtime environment tab:

Image loading...Haskell action image

Tip

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

3.2 Deploy application to server

The built app needs to be uploaded to the server. Head to the Transfer section and select your deployment action (SFTP in our case):

Image loading...File transfer actions

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

Image loading...Setting up an 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:

Image loading...SSH action selection

Enter the commands to execute and configure authentication details:

Image loading...Command console

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:

Image loading...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. Image loading...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! 🔥
