IBM Cloud Functions runtime for nodejs

Build Status

The runtime provides nodejs v8 with a set of npm packages The runtime provides nodejs v10 with a set of npm packages

The runtime provides the following npm packages for IBM Cloud:

*Note: Nodejs10 runtime does not include DB2 or Watson npm package, this will be added soon.

How to use as a docker Action

To use as a docker action

bx wsk action update myAction myAction.js --docker ibmfunctions/action-nodejs-ibm-v8

This works on any deployment of Apache OpenWhisk or IBM Cloud Functions

Future: IBM Cloud Functions (based on Apache OpenWhisk)

To use as a nodejs kind action

bx wsk action update myAction myAction --kind nodejs:8

Tip: Not available yet in the IBM Cloud

Working with the local git repo

Prerequisite: Export OPENWHISK_HOME to point to your incubator/openwhisk cloned directory.

To build the nodejs:8 runtime:

./gradlew nodejs8:distDocker

This will produce the image whisk/action-nodejs-ibm-v8

To build the nodejs:10 runtime:

./gradlew nodejs10:distDocker

This will produce the image whisk/action-nodejs-ibm-v10

Build and Push image

docker login
./gradlew nodejs10:distDocker -PdockerImagePrefix=$prefix-user -PdockerRegistry=docker.io

Deploy OpenWhisk using ansible environment that adds the new king nodejs:10 Assuming you have OpenWhisk already deploy localy and OPENWHISK_HOME pointing to root directory of OpenWhisk core repository.

Set ROOTDIR to the root directory of this repository.

Redeploy OpenWhisk

cd $OPENWHISK_HOME/ansible
ANSIBLE_CMD="ansible-playbook -i ${ROOTDIR}/ansible/environments/local"
$ANSIBLE_CMD setup.yml
$ANSIBLE_CMD couchdb.yml
$ANSIBLE_CMD initdb.yml
$ANSIBLE_CMD wipe.yml
$ANSIBLE_CMD openwhisk.yml

To use as docker action push to your own dockerhub account

docker tag whisk/action-nodejs-ibm-v10 $user_prefix/action-nodejs-ibm-v10
docker push $user_prefix/action-nodejs-ibm-v10

Then create the action using your the image from dockerhub

wsk action update myAction myAction.js --docker $user_prefix/action-nodejs-ibm-v8

The $user_prefix is usually your dockerhub user id.

Testing

Install dependencies from the root directory on $OPENWHISK_HOME repository

./gradlew install

Using IntelliJ:

  • Import project as gradle project.
  • Make sure working directory is root of the project/repo

Using Gradle

To run all tests: ./gradlew tests:test this include tests depending on credentials

To run all tests except those which do not rely on credentials ./gradlew tests:testWithoutCredentials

To run a single test-class: ./gradlew tests:test --tests <SomeGradleTestFilter>

For example, in order to execute the tests in /tests/src/test/scala/actionContainers/IBMNodeJSActionDB2Tests.scala, run: ./gradlew tests:test --tests *IBMNodeJsActionDB2Tests

Note: If you're running all tests locally with credentials like ./gradlew tests:test or ./gradlew tests:test --tests *CredentialsIBMNodeJsActionWatsonTests you need to set up a tests/credentials.json file containing Watson credentials in the format of:

{
  "language_translation":[
    {
      "credentials": {
        "url": "",
        "password": "",
        "username": ""
      }
    }
  ],
  "cloudantNoSQLDB":[
    {
      "credentials": {
        "url": "",
        "host": "",
        "port": "" ,
        "password": "",
        "username": ""
      }
    }
  ],
  "dashDB":[
      {
        "credentials": {
          "ssldsn": "DATABASE=BLUDB;HOSTNAME=<hostname_value>;PORT=50001;PROTOCOL=TCPIP;UID=<username_value>;PWD=<password_value>;Security=SSL;"
        }
      }
    ]
}

Then update the whisk.properties file located in the directory $OPENWHISK_HOME, using the variable vcap.services.file
