Openwhisk: Installing openwhisk in multiple nodes

[sangroad]

Hello guys, I'm trying to set up openwhisk in 3 ubuntu 16.04 nodes.
I want to install openwhisk to have one master node and two slave node on three Ubuntu 16.04 nodes.
However, I couldn't find the appropriate documentation.
So I looked for several issues, but I couldn't get the answer I wanted.
The closest I found was using Jenkins, but I couldn't use it because I'm not using VMs.
I'm also tried adding an invoker to the ansible/environment/local/hosts.j2.ini file in master node, but there is an error that invokers could not pull whisk/invoker image.
What should I do to install openwhisk on multiple nodes?

Currently, we are install openwhisk via jenkins with ansible, steps as below

• Prepared several machines
  
  
  
  • make sure install docker(this is ours: 18.06.3-ce)
  
  
  • check your kernel version(this is ours:4.16.1-1.el7.elrepo.x86_64 #1 SMP Sun Apr 8 10:21:51 EDT 2018 x86_64 x86_64 x86_64 GNU/Linux)
  
  
  • add your jenkins's pubKey to all your machines(make sure jenkins machine can connect other machines without username/password)
  
  
  • check machines whether can pull openwhisk runtime images
  
  
  • install some init lib
  
  

sudo easy_install pip
sudo pip install jsonschema
sudo pip install argcomplete
sudo pip install couchdb
sudo pip install markupsafe
sudo pip install docker-py
sudo pip install httplib2==0.9.2
sudo pip install requests==2.10.0
 ```
* Prepare script (just example)
 ```

ansible ansible_connection=local

Thanks a lot!
I'll try using Jenkins with ansible.
