Apache OpenWhisk runtimes for Python

Give it a try today

To use as a docker action using python 3

wsk action update myAction myAction.py --docker openwhisk/python3action:1.0.2

Replace python3action with python2action to use python 2.

To use on deployment that contains the rutime as a kind

To use as a kind action using python 3

wsk action update myAction myAction.py --kind python:3

Replace python:3 with python:2 to use python 2.

Python 3 AI Action

This action enables developers to create AI Services with OpenWhisk. It comes with preinstalled libraries useful for running machine learning and deep learning inferences. See more about python3aiaction.

Local development

./gradlew core:pythonAction:distDocker

This will produce the image whisk/python3action

Build and Push image

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

Replace core:pythonAction with core:python2Action to build python 2 instead.

Deploy OpenWhisk using ansible environment that contains the kind python:3 and python:2 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

Or you can use wskdev and create a soft link to the target ansible environment, for example:

ln -s ${ROOTDIR}/ansible/environments/local ${OPENWHISK_HOME}/ansible/environments/local-python
wskdev fresh -t local-python

To use as docker action push to your own dockerhub account

docker tag whisk/python3action $user_prefix/python
docker push $user_prefix/python3action

Then create the action using your the image from dockerhub

wsk action update myAction myAction.py --docker $user_prefix/python3action

The $user_prefix is usually your dockerhub user id. Replace python3action with python2action to use python 2

Testing

Install dependencies from the root directory on $OPENWHISK_HOME repository

./gradlew install

Using gradle for the ActionContainer tests you need to use a proxy if running on Mac, if Linux then don't use proxy options You can pass the flags -Dhttp.proxyHost=localhost -Dhttp.proxyPort=3128 directly in gradle command. Or save in your $HOME/.gradle/gradle.properties

systemProp.http.proxyHost=localhost
systemProp.http.proxyPort=3128

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
Add the following Java VM properties in ScalaTests Run Configuration, easiest is to change the Defaults for all ScalaTests to use this VM properties

-Dhttp.proxyHost=localhost
-Dhttp.proxyPort=3128

Disclaimer

Apache OpenWhisk Runtime Python is an effort undergoing incubation at The Apache Software Foundation (ASF), sponsored by the Apache Incubator. Incubation is required of all newly accepted projects until a further review indicates that the infrastructure, communications, and decision making process have stabilized in a manner consistent with other successful ASF projects. While incubation status is not necessarily a reflection of the completeness or stability of the code, it does indicate that the project has yet to be fully endorsed by the ASF.
