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:1.0.0
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.
