Hi Michele, 

Congratulations on the O'Reilly book proposal acceptance!
I also suggest including wskadmin in the Appendixes.

Another suggestion for the Appendixes is Lean OpenWhisk:
I believe it will be merged by the time you write the book.

Thank you.

Hi Michele,

Congratulations for getting an O'Reilly contract. That's awesome!
Also, this list is totally the right place for this topic (IMO).

I have a little comment about the TOC: the way I read it your intended 
audience are OW users (action developers), not developers of OW itself. Is 
that right? However, even for the former group it is often helpful to know 
how their action code actually gets executed. So maybe a chapter about the 
internal architecture of OW would be helpful.

    Hello all, 
    I am not sure if it is appropriate to talk of this on the mailing list 
or not. If not please let me know and I will stop immediately and 
apologize for this post. I assume for now it is acceptable (because I saw 
similar discussions on other mailing lists on the Apache Group), so I post 
    As some community members already know,  I wrote some chapters (6) of 
a book on OpenWhisk (so you know what you did when I disappeared for a few 
months :)), then I was close to release it as open source and I asked what 
to do of them on the Slack channel.  In a sense the book was complete and 
ready to release.
    To my surprise, instead of recommending to release the book as Open 
Source I was told instead that publishing it with a prestigious editor 
would have been better. 
    So I dared to propose the book to the (IMHO) most prestigious 
technical publisher I know, O'Reilly, and guess what, the book was 
    The chapters I wrote so far focus on Javascript. However, I was 
recommended (by Carlos and Rodric) not to talk only of Javascript. There 
is a lot of stuff on Javascript people are looking for learning about 
other languages.
    So I ended up with a plan to cover also Python and Go.
    This is the planned TOC so far. I am asking for opinions on it:
    TItle: Learning OpenWhisk
    Part1: Introducing Serverless Development  in JavaScript
    - Serverless and OpenWhisk Architecture
    - A Simple Serverless Application in JavaScript
    - OpenWhisk CLI and JavaScript API
    - Common Patterns in OpenWhisk 
    - Integration Patterns in OpenWhis
    - Testing OpenWhisk Applications
    Part 2: Advanced Serverless Development in Python and GoLang
    - Using Python in OpenWhisk
    - Using Databases in OpenWhisk
    - Creating an Alexa Skill in Python
    - Using GoLang in OpenWhisk
    - Using Message Queues in OpenWhisk
    - Creating a Slackbot in GoLang
    - Deployment with wskdeploy
    - Installing OpenWhisk in Kubernetes
    The key concern is if a similar TOC is acceptable and making the best 
compromise, or the book could be too wide (and hard to read) for the 
potential audience. 
    In my opinion, it should be a good compromise between completeness 
without requiring too many skills. But here I am open to hearing other 
opinions. For example, I thought to stick only to javascript but then I 
would lose more advanced aspects that can be of interests to many 
    Note I can share freely drafts or chapters of the book with members of 
the community is interested. Contact me privately. But keep in mind the 
publisher give me only 10 free copies so I cannot promise too many printed 
free copies :) :) :)
    PS: the Animal!  You know each O'Reilly book has an animal in the 
cover. After a lot of thinking, I proposed an animal not yet used but I 
think it fits a lot OpenWhisk: the Pagurus (
). Do you like the idea?
