JClouds Plugin for Jenkins

JClouds Jenkins plugin provides option to launch jenkins slaves on any Cloud provider supported by JClouds (http://jclouds.apache.org/reference/providers/).

Configuration Options

You can add a new Cloud in the Jenkins configuration. The plugin requires the cloud provider type (as per JClouds Compute API provider list), access id and secret key. You can generate a keypair that will be used to connect and configure the slave.

The list of providers is an auto-complete field. There's an option to test the connection settings, which will validate your credentials. A new node can be launched via Jenkin's computer list (build executors) screen.

We are working on more configuration options to configure auto-provisioning and limits etc.

Building and Running

You can build and test this plugin using by cloning this repository and

mvn clean install hpi:run

The above command will start jenkins with JClouds plugin pre-configured.

Adding a new Cloud Provider

  • Goto Jenkins Configuration page by clicking on Manage menu or browsing to the URL http://localhost:8080/configure
  • Scroll down to Cloud Section
  • Click on the Add a new cloud pop-up menu button which should have an option - Cloud (JClouds)
  • Click on Cloud (JClouds)
  • Fill in the configuration options

    • Profile : the name of the profile e.g, aws-slave-profile
    • Provider Name: type first two characters and you'll get an auto-completed provider name (e.g. aws-ec2 or hpcloud-compute)
    • End Point URL: if your provider API needs an endpoint configuration, add it here, otherwise leave it empty.
    • Max Number of Instances: The maximum number of instances to run from this cloud at one time.
    • Retention Time: How long, in minutes, to wait for a slave to remain idle before disconnecting and terminating it. Defaults to 30.
    • Identity : your accessId
    • Credential: your secret key
    • RSA Private Key/Public Key: If you have a keypair, then just copy paste the public and private key parts, otherwise click on Generate Key Pair button.
    • Click on Test Connection to validate the cloud settings.
  • Add Cloud Instance Template by clicking on the Add button

  • Fill in configuration options:

    • Name : the name of the instance template e.g. aws-jenkins-slave
    • Number of Executors: How many executors each slave created from this template should have.
    • Description: notes/comments for your reference.

    • Image ID: Image ID to use for this slave template, such as EC2 AMIs. Note that EC2 AMIs must include the region as well, e.g., "us-east-1/ami-00000". or

    • OSFamily: Specify the OSFamily - leave empty for default for a cloud provider
    • OS Version : Specify the OSVersion - leave empty for default for a cloud provider

    • Hardware ID: Hardware ID on provider for this slave template, such as "t1.micro" on AWS EC2. or

    • RAM : in MB
    • No. of Cores: number of virtual processor cores.

    • Location ID: Location ID where this slave will be deployed. If none is selected jclouds will automatically choose an available one.

    • Labels: (space-separated) labels/tags that you can use to attach a build to this slave template

    • Init Script: A shell script to be run when the slave is created.
    • Stop on Terminate: If true, suspend slaves rather than terminating them.
  • Click Save to save the configuration changes.

  • Goto Jenkins' home page, click on Build Executor Status link on the sidebar.
  • Verify that you have a button with `Provision via JClouds - {YOUR PROFILE NAME} drop down with the slave template name you configured.
  • Click on the slave and see if your slave launched succesfully (please wait until the operation completes).

Executing build on the slave

  • To run your build on the newly configured slave computer, just enable the Restrict where this project can be run option in the build configuration page.
  • Enter the label which you choose for the instance template in the Label Expression text field. This should auto-complete labels for you.
  • Click save the save the configuration options.
  • Schedule the build to check whether the build is executed on the selected slave template.

Adding a Blobstore Profile for storing build artifacts

The plugin also provides a way to store your build artifacts on JClouds supported cloud storage providers. You can configure multiple blobstore profiles and configure the build to copy different files/artifacts to the specified container. Here's how you configure the same.

  • Goto Jenkins Configuration Page
  • Click Ad under the section JClouds Cloud Storage Settings
  • Provide the configuration Options:
  • You can add multiple providers by clicking on Add.
  • Click Save on the bottom of the page, to save the settings.

Publishing artifacts after a build

After you configure a cloudstorage provider, you can enable the publishing file by enabling it under Post-build Actions in the build job configuration page.

  • Click on the checkbox Publish artifacts to JClouds Clouds Storage
  • You should now see a dropdown with configured storage profiles. Select the one you want to use for this build.
  • Click on Add button next to Files to upload.
  • Add the sourcd file path (relative to workspace)
  • Add the destination container name.
  • Add the virtual path under the container to copy to. (optional)
  • Check the Keep Hierarchy box if you want the path of the file relative to the workspace to be appended to the virtual path.
  • Repeat to add more files if you want to copy.
  • Click save.

When the build is complete and succesful, the configured files will be published to the configured blobstore.
