Apache OpenWhisk runtimes for docker

Give it a try today

Create a zip action with a exec in the root of the zip

echo \
'#!/bin/bash
echo "{\"messag\":\"Hello World\"}"' > exec

chmod +x exec
zip myAction.zip exec

Create the action using the docker image for the runtime

wsk action update myAction myAction.zip --docker openwhisk/dockerskeleton:1.3.2

This works on any deployment of Apache OpenWhisk

To use on a deployment that contains the runtime deployed

Create action using --native

wsk action update myAction myAction.zip --native

Local development

./gradlew :core:actionProxy:distDocker :sdk:docker:distDocker

This will produce the image whisk/dockerskeleton

Build and Push image

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

Deploy OpenWhisk using ansible environment that contains the runtime of type blackboxes with name dockerskeleton 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-docker
wskdev fresh -t local-docker

To use as docker action push to your own dockerhub account

docker tag whisk/dockerskeleton $user_prefix/dockerskeleton
docker push $user_prefix/dockerskeleton

Then create the action using your image from dockerhub

wsk action update myAction myAction.zip --docker $user_prefix/dockerskeleton

The $user_prefix is usually your dockerhub user id.

Disclaimer

Apache OpenWhisk Runtime Docker 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.
