Using the Deploy Package

The /whisk.system/deploy package offers a convenient way for you to describe and deploy any part of the OpenWhisk programming model using a Manifest file written in YAML.

The package includes the following actions.

/whisk.system/deploypackagePackage to deploy OpenWhisk programming model elements
/whisk.system/deploy/wskdeployactiongitUrl, manifestPath, envDataDeploy from github repositories with the appropriate structure and a defining manifest.

wskdeploy Parameters

The /whisk.system/deploy/wskdeploy package deploys OpenWhisk assets from a github repository with a defining manifest. The parameters are as follows:

  • gitUrl: A string specifying the location of the github repository containing the assets to be deployed. For example: https://github.com/ibm-functions/template-cloudant-trigger

  • manifestPath: Optional. A string specifying the location of the folder enclosing the manifest.yaml file. For example: src/openwhisk. If this parameter is not provided, it will default to the root of the github repo.

  • envData: Optional. A string with a json object providing any optional environment data specified by the manifest.yaml file. For example:

      "CLOUDANT_HOSTNAME": "some-hostname-bluemix.cloudant.com",
      "CLOUDANT_USERNAME": "some-username",
      "CLOUDANT_PASSWORD": "my-password",
      "CLOUDANT_DATABASE": "database-name"

Setting up your Repository

A simple hello world example of a deployable github repository can be found here.

A more complex example of a deployable github repository, including a trigger, a sequence, and cloudant credentials can be found here.

  1. Create a github repository with a manifest.yaml at its root, and an actions directory containing any source files.
  • actions
    • my_action_name.js
  • manifest.yaml

If you would like the manifest.yaml file to be in a different location, you can do so, but you'll need to pass in the optional manifestPath parameter to let wskdeploy know where the file is.

  • src
    • ...
    • manifest.yaml
  • test
  1. Please see the above referenced repositories for samples of the manifest.yaml. The manifest.yaml describes the OpenWhisk elements to be created. There is a great guide for writing manifests here.

Run the wskdeploy command

With the repository created, you can now deploy from it.

  • For the simplest manifests, with no associated services you can run the command with a gitUrl parameter, and a manifestPath parameter which tells wskdeploy which language you want from your project.

    wsk action invoke /whisk.system/deploy/wskdeploy
    -p gitUrl https://github.com/ibm-functions/template-hello-world/
    -p manifestPath "src/openwhisk"

Working with repository

Deploying the Deploy Package using installCatalog.sh

  1. git clone https://github.com/openwhisk/incubator-openwhisk-package-deploy
  2. cd incubator-openwhisk-package-deploy/packages
  3. ./installCatalog.sh AUTH EDGE_HOST WSK_CLI DOCKER AUTH is your auth key. EDGE_HOST is the OpenWhisk hostname. WSK_CLI is location of the Openwhisk CLI binary. DOCKER is an optional param for the desired wskdeploy docker image, resolves to openwhisk/wskdeploy:0.9.3 by default.

You can also remove the package using uninstall.sh in a similar fashion like so: ./uninstall.sh AUTH EDGE_HOST WSK_CLI
