• The runtime providespython v3.11 with a set ofpython packages, seepython3.11/CHANGELOG.md
• The runtime providespython v3.9 with a set ofpython packages, seepython3.9/CHANGELOG.md

Some of the python packages are to be used onIBM Cloud:

• IBM DB2/DashDB and IBM Informix - Python SDKibm_db
• IBM Cloudant - Python SDKcloudant
• IBM Watson Developer Cloud - Python SDKwatson-developer-cloud
• IBM Cloud Object Storage - Python SDKibm-cos-sdk
• IBM Cloud SQL Query service - Python Clientibmcloudsql

Docker runtime is based on Debian/Ubuntu

Write a function usingApache OpenWhisk Serverless programming inteface

defmain(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 youropenwhisk cloned directory.

./gradlew python3:distDocker

This will produce the imagewhisk/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 kingpython:3Assuming you have OpenWhisk already deploy localy andOPENWHISK_HOME pointing to root directory of OpenWhisk core repository.

SetROOTDIR to the root directory of this repository.

Redeploy OpenWhisk

cd $OPENWHISK_HOME/ansibleANSIBLE_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-v3docker 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-v3docker 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 3.11python:3.11-stretch.
  • If there is a new version check that the tag used inpython3.11/Dockerfile is using the latest tag foropenwhisk/actionloop-python-v3.11
  • Update the ibm imagepython3.11/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"

  • Updatepython3.11/requirements.txt
  • Updatepython3.7/CHANGELOG.md

• Check if there are new pip packages available

  • Updatepython3.9/requirements.txt only minor and patch levels.
  • Updatepython3.9/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 thelatest tag for each runtime.

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