• used toolchain and git: https://github.com/BenediktKrueger/masterThesisBot

• function can be called with or without params: https://console.bluemix.net/docs/openwhisk/openwhisk_actions.html#openwhisk_actions

• problematic with external npm packages is that they have to be installed first

  • first run it locally
  • create js file and package.js with dependecies
  • run npm install local
  • zip everything into a file and than run wsk --> wsk action create packageAction --kind nodejs:default action.zip

• setup Bluemix CLI

• setup CloudFoundry pLugin

• setup wsk CLI

• sso in console with temporary code

cd C:\Users\IBM_ADMIN\Box Sync\Work\Coding\0masterarbeit\Github\masterThesisBot

1. wsk.exe download
2. wsk.exe from CLI
3. in local cli --> wsk bluemix login --sso --namespace [email protected]_ben
4. export whisk auth --> wsk property get --auth --> text.txt
5. prepare cli in deploy pipeline with script and use whisk auth
6. test action --> wsk action invoke --blocking --result conversationPackage/packageAction --param lines "["and now", "for something completely", "different" ]"

• develop openwhisk locally and push automatically to git

• normally necessary to deploy to cloud before testing the code

• how to do it local: https://www.raymondcamden.com/2017/01/09/quick-tip-for-testing-openwhisk-actions-locally

• lately I'm into serverless architectures

• they are for some kind of applications like chatsbots or iot applications my preffered way

• still i don't see a lot projects using them

• without thinking about automatic deployment and using git its easy to setup and usable

• I want to show how i configured an automatic pipeline in order to deploy automatically after a new push

• using external npm packages and dependencies as well

• explain process general process

• there are some usefull preinstalled libaries like request to perform api calls

• start with the project setup - git, local testing, development, automatic deployment, example installation of conversation service (external npm packages)

• but not a lot of different preinstalled packages so what can you do?

• install them an abuse of the concept??

• concept of serverless

• one of the disadvatages of serverless approach is that developer basically rely on provider of the service for devOps tools

• example conversation service - create a conversation service and copy the username, password, and version into environment variables

• Usage of environment variables via deploy script

• need to create a package in script and add to this package environment variables to ensure security e.g. for credentials

• in code you can easily use them

• open tasks: if in built script for first time create/ afterwards update

  • local running of code
