ACS development

[CK <cl...@gmail.com>]

Hi

I am new to ACS development and intend on using DevCloud2 as my self
contained dev+test environment. I have the management server running in
VirtualBox and have browsed the ACS website/wiki and not found answers to
the following questions and hope you can help:

1) Where can I find the management-server log in DevCloud2?

2) What is the 192.168.56.1 IP used for and where is it set?

3) By default the 'host' configuration parameter in DevCloud2 is set to
192.168.56.1, why is this? I would expect it to be set to 192.168.56.10

4) How do I start the Cloud_Usage service (does it need to be built first,
if so how)?

5) How do I access/read from the ACS Event Bus? Is there any sample code to
do this - in python ideally?

Thanks in advance

Yes, it won't run it as a background job. You can well have mvn run it in
background though. The development and production workflows are slightly
different but they will run the same mgmt server anyway.

If it bothers you just run in a tmux session (or screen etc.) and detach it
and continue your work and reattach tmux when needed.

Other way is to create release debs/rpms and install from it which could be
buggy and may need some work because 4.2 has a lot of new dependencies and
possible path and name changes.

HTH.

Cheers.

Thanks Rohit.

I found vmops.log under src, I assume that is the management server log?

In DevCloud2, is the command to run the management server: mvn -pl
:cloud-client-ui jetty:run
but this does not run in the background, can I add & to make it so, or is
there another command I should be using to run the management server as a
service, similar to a normal ACS deployment?

Since you're running the mgmt server in VirtualBox, it would be in the src
directory from where you've built ACS and running it.

2) What is the 192.168.56.1 IP used for and where is it set?

For DevCloud2 we're using host-only interface which is a virtual network
device created by VBox which has this IP. If you want to have some other
IP/network you can do so using VBox's network preference. In such case
you're also have to reconfigure the ethernet interface on DevCloud2 as well.

Yes, the default/assumed use case is that you're developing on your host OS
(so 56.1) and using some IDE etc. to debug etc. that's why the default host
value is 56.1. You can change it and restart mgmt server or use/fix in the
sql/jsons in tools/devcloud etc.

There's a wiki on it, could you try to search I don't remember now. Or if
it's missing Kishan can give us pointers.

AFAIK ACS uses RabbitMQ for the messaging middleware. You can use any AMQP
lib, I would suggest using pika for Python with which you can easily write
consumers of the event bus (queue). Search the wiki for the nitty gritty
details on the routing keys, exchanges etc. on how to use the event bus.

Hope this helps.

Cheers.
