IBM Cloud Functions reached end of life and this repository is no longer active.

For Apache OpenWhisk visit: https://github.com/apache/openwhisk.

• The runtime provides python v3.11 with a set of python packages, see python3.11/CHANGELOG.md
• The runtime provides python v3.9 with a set of python packages, see python3.9/CHANGELOG.md

Some of the python packages are to be used on IBM Cloud:

• IBM DB2/DashDB and IBM Informix - Python SDK ibm_db
• IBM Cloudant - Python SDK cloudant
• IBM Watson Developer Cloud - Python SDK watson-developer-cloud
• IBM Cloud Object Storage - Python SDK ibm-cos-sdk
• IBM Cloud SQL Query service - Python Client ibmcloudsql

Docker runtime is based on Debian/Ubuntu

Write a function using Apache OpenWhisk Serverless programming inteface

def main(args):
    name = args.get("name", "stranger")
    greeting = "Hello " + name + "!"
    print(greeting)
    return {"greeting": greeting}

To use as a python kind action

bx wsk action update helloPython hello.py --kind python:3.11

To use as a docker action

bx wsk action update helloPython hello.py --docker ibmfunctions/action-python-v3.11

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

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

./gradlew python3:distDocker

This will produce the image whisk/action-python-v3.11

Build and Push image

docker login
./gradlew python3.11:distDocker -PdockerImagePrefix=$prefix-user -PdockerRegistry=docker.io

Deploy OpenWhisk using ansible environment that adds the new king python:3 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-python-v3 $user_prefix/action-python-v3
docker push $user_prefix/action-python-v3

Then create the action using your the image from dockerhub

wsk action update myAction myAction.py --docker $user_prefix/action-python-v3

The $user_prefix is usually your dockerhub user id.

Install dependencies from the root directory on $OPENWHISK_HOME repository

./gradlew install

Using gradle to run all tests

./gradlew :tests:test

Using gradle to run some tests

./gradlew :tests:test --tests *ActionContainerTests*

Using IntelliJ:

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

To use as docker action push to your own dockerhub account

docker tag whisk/action-python-v3 $user_prefix/action-python-v3
docker push $user_prefix/action-python-v3

Then create the action using your the image from dockerhub

wsk action update myAction myAction.py --docker $user_prefix/action-python-v3

The $user_prefix is usually your dockerhub user id.

• Check if there is a new version for Python 3.11 python:3.11-stretch.
  • If there is a new version check that the tag used in python3.11/Dockerfile is using the latest tag for openwhisk/actionloop-python-v3.11
  • Update the ibm image python3.11/Dockerfile FROM usign the new upstream tag
• Check if there are new pip packages available
  • Use the latest released image to check the outdated pip packages

  docker run --rm -it ibmfunctions/action-python-v3.11:1.4.0 sh -c "pip list --outdated"
  

  • Update python3.11/requirements.txt
  • Update python3.7/CHANGELOG.md

• Check if there are new pip packages available
  • Use the latest released image to check the outdated pip packages

  docker run --rm -it ibmfunctions/action-python-v3.9:1.1.0 sh -c "pip list --outdated"
  

  • Update python3.9/requirements.txt only minor and patch levels.
  • Update python3.9/CHANGELOG.md

• After the PR is merged and the master pass the build, checkout master.
• Create tag for each runtime and push upstream

git tag 3.11@<new version>
git push upstream 3.11@<new version>

• After the image is deployed to production update the latest tag for each runtime.

git tag 3.11@latest -f
git push upstream 3.11@latest -f
