#IBM Functions runtimes for nodejs

This repository is work in progress, braking changes might occur

The runtime provides nodejs v8 with a set of npm packages The images provides the following npm packages for IBM Services/Products

• IBM DB2/DashDB and IBM Informix [email protected]
• IBM Cloudant [email protected]
• IBM Watson Cloud [email protected]

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

To use as a special nodejs kind action

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

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

./gradlew nodejs8:distDocker

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

Build and Push image

docker login
./gradlew nodejs8:distDocker -PdockerImagePrefix=$prefix-user -PdockerRegistry=docker.io

Deploy OpenWhisk using ansible environment that adds the new king nodejs-ibm:8 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-v8 $user_prefix/action-nodejs-ibm-v8
docker push $user_prefix/action-nodejs-ibm-v8

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.

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":[
    {
      "name":"",  
      "label":"",  
      "plan":"",  
      "credentials": {  
        "url": "",  
        "host": "",  
        "port": "" ,  
        "password": "",  
        "username": ""  
      }  
    }
  ]
}  

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