Launching multiple apps when starting Brooklyn

[Abhishek Sharma <ab...@gmail.com>]

Hey guys,

I am trying to make Brooklyn start my node.js web application and also a
drop-wizard based java service. I am using Java Blueprints and not YAML.

How do I make brooklyn start multiple applications ?
My goal is to start these based on a command line parameters passed when
starting brooklyn.

Thanks in advance,
Abhi

Graeme,

First option sounds great. Yes, I would like to work on that and get a PR
merged into Brooklyn with your help.
I will take a look into the airline framework until then and pull the
codebase. I know you guys have changed the code structure and moved things
around.

Let us tackle this once you are back from vacation. I am off a few days
myself.

And again thanks so much for the help from all of you. Really appreciate
it.
Already in love with Brooklyn :)

Thanks.
Abhishek

Re: Launching multiple apps when starting Brooklyn

[Graeme Miller <gr...@cloudsoftcorp.com>]

Hi Abhishek,

The Brooklyn Main class is used to set properties on BrooklynLauncher,
which is in turn responsible for running the Brooklyn instance. The
BrooklynLauncher can already be configured with multiple applications
(appsToManage variable).

So there are two things I can suggest here. Firstly, the cleanest
solution would be to modify the Brooklyn Main class so that the -a option
takes in multiple applications and hands them to the launcher. This
shouldn't be too complicated, we use a framework called airline
<https://github.com/airlift/airline> to handle the CLI options.

If that is not going to be possible, a quick solution would be to override
the Main.customize method and add multiple applications there, in a similar
way to how the Main.computeAndSetApp method does.

If you go with the first option, I am more than happy to lend a hand. We
can even create a PR and get it merged back into Brooklyn main.

Just a heads up, as it is Christmas things might get delayed a little. I am
on Holiday, back on the 5th of Jan (I will be in the office on Wed the 30th
of December).

Regards,
Graeme

Grame,

Until you get a chance to respond to my earlier email.

The YAML approach of starting that app works like a charm. Thanks..

Thanks,

Re: Launching multiple apps when starting Brooklyn

[Abhishek Sharma <ab...@gmail.com>]

Thanks for the inputs, Graeme.

It is necessary for me to go beyond the YAML approach you mentioned. Would
deeply appreciate if you can give me pointers on how that can be done.

Here are few of my top reasons:
1. I want to be able to deploy my services (built on Brooklyn) on bare
metal, IaaS and any PaaS that we plan to support. I want a single entry
point and ease for deployment.
So based on a particular custom added CLI options I change by
brooklyn.properties files to run services with particular settings.

2. We have done a lot of stuff in Java Blueprints and want to keep it that
way.

3. Based on certain flags that are set we have some existing code that
initializes some Guice modules.

I do not want to disrupt all that for now and just have my ApplicationMain
class which extends Brooklyn Main class start multiple applications.
The locations, environment etc all other settings are specified in java
classes already for my services. Just want to be able to run multiple
services from Main class.

Thanks,
Abhishek

Re: Launching multiple apps when starting Brooklyn

[Graeme Miller <gr...@cloudsoftcorp.com>]

Hello,

I can try this. Is there an actual code example of such a kind you can
point me to ?

The three lines I provided in the previous email should be enough, just
replace "com.abhishek.dropwizzard" and "com.abhishek.nodejs" with your
classes and set the '-a' option to point to the YAML file. You'll also need
to specify a location either in the yaml or via the '-l' option.

1. Treating Brooklyn as my central guy for deploying and monitoring all my
services

Would highly recommend it :)

2. I have extending the Main class and added some custom flags for my own
needs. I also extend the main.launch command and use my own. Were I have
over-ridden the call method. I use setAppToLaunch() to set the app I want
to launch. I was looking for some way to set multiple apps.

Would not recommend this unless necessary. Apart from multiple apps, what
else is required? It is possible that this can be done via YAML, which
should be easier to use.

The Yaml file option you mentioned must also have to do something on
similar lines, can I do something similar is my own AppMain which extends
Brooklyn's Main Class.

See above, what else would it need to do?

Another option would be to use the Brooklyn CLI which is currently being
developed, see here <https://github.com/brooklyncentral/brooklyn-cli>.
Please note this is a fairly new project that is under active development.

Regards,
Graeme

Re: Launching multiple apps when starting Brooklyn

[Abhishek Sharma <ab...@gmail.com>]

Hey Graeme,

I can try this. Is there an actual code example of such a kind you can
point me to ?

Although, Ideally I would like to be able to do this from Java code itself.
The way I am looking at this is following:

1. Treating Brooklyn as my central guy for deploying and monitoring all my
services

2. I have extending the Main class and added some custom flags for my own
needs. I also extend the main.launch command and use my own. Were I have
over-ridden the call method. I use setAppToLaunch() to set the app I want
to launch. I was looking for some way to set multiple apps.

The Yaml file option you mentioned must also have to do something on
similar lines, can I do something similar is my own AppMain which extends
Brooklyn's Main Class.

Thanks,
Abhi

Re: Launching multiple apps when starting Brooklyn

[Graeme Miller <gr...@cloudsoftcorp.com>]

Hi Abhishek,

The Brooklyn launch command allows you to specify an application with the
'-a' option. However, it only allows you to specify one application.

This specified application can be either a Java Class or a YAML file. One
solution to this would be to write a small YAML file that defines an
application that starts both your node.js and drop-wizard entities. The
file would contain only three lines:

> services:

   - type: com.abhishek.dropwizzard

   - type: com.abhishek.nodejs



You can then use the YAML file as the -a option. Would that be a suitable
solution?

Regards,
Graeme
