Hi all again,
Andrea and me are integrating Cloud Foundry services according to
our last
proposal description (below).
An entity has beed developed which represents generic Cloud Foundry
services and a more complex
entity is focuses on MySql Cloud Foundry service (
VanillaCloudFoundryApplication).
VanillaCloudFoundryApplication allows create an instance of a
available
MySql service
in the Cloud Foundry Platform, as you can see in the next blueprint.
name: Vanilla CloudFoundry example
location: pivotal-ws
services:
- type: org.apache.brooklyn.cloudfoundry.entity.
VanillaCloudFoundryApplication
id: vanilla-app
brooklyn.config:
path:
classpath://brooklyn-example-hello-world-sql-webapp-in-paas.war
buildpack: https://github.com/cloudfoundry/java-buildpack.git
services:
- $brooklyn:component("db”)
env:
brooklyn.example.db.url: $brooklyn:component("db").
attributeWhenReady("service.mysql.jdbc")
- type: org.apache.brooklyn.cloudfoundry.entity.service.
mysql.CloudFoundryMySqlService
id: db
brooklyn.config:
serviceName: cleardb
instanceName: my-cleardb-instance
plan: spark
creationScriptTemplateUrl: classpath://chat-database.sql
You can see that CloudFoundryMySqlService creates an instance of a
available mysql service (in this case cleardb),
initializes the database using a script.sql and and provides a jdbc
database address through a sensor (service.mysql.jdbc).
It allows services to be created by an blueprint together with the
application (which is not supported currently
by Cloud Foundry Manifest). Moreover, it is in charge of
initializing the
database (whether may be useful for users).
So, we have a first working implementation of our proposal. Some
unit and
live test have been developed and it
looks that we are taking a step in the right direction.
With the help of Andrea (thanks a lot for that) I was able to solve
some
questions about the services data management,
we would like to know your opinion about some decisions that we are
still
considering, but let me stop here and share our
questions in a different email, in order to avoid a long and
unreadable
mail.
Thanks a lot.
Best,
Jose

Hi all,
as we mentioned previously, we have a pretty entity which allows an
application to be deployed on a Cloud Foundry platform by using a
new paas location, CloudFoundryPaasLocation.
Here you can find a simple blueprint which shows the entity usage:
name: CloudFoundryPaasLocation configuration example
location: pivotal-ws
services:
- type: org.apache.brooklyn.cloudfoundry.entity.
VanillaCloudFoundryApplication
id: vanilla-app
brooklyn.config:
name-app: name
path:
classpath://brooklyn-example-hello-world-sql-webapp-in-paas.war
buildpack: https://github.com/cloudfoundry/java-buildpack.git
domain: domain
host: application-host
You can find more examples in [1]. Currently, we are thinking about
supporting
Cloud Foundry service. Documentation [2] says that an existent
service
can be
bound to an application. Then, it looks interesting to use a new
entity
to instantiate
a service, allowing users to create services and bind them to an
application
from a blueprint.
Following, you can find blueprint which shows my proposal to manage
a
service.
name: CloudFoundryPaasLocation configuration example
location: pivotal-ws
services:
- type: org.apache.brooklyn.cloudfoundry.entity.
VanillaCloudFoundryApplication
id: vanilla-app
brooklyn.config:
name-app: name
path:
classpath://brooklyn-example-hello-world-sql-webapp-in-paas.war
buildpack: https://github.com/cloudfoundry/java-buildpack.git
domain: domain
host: application-host
bind:
- instance_name
- type:
org.apache.brooklyn.cloudfoundry.entity.servies.MySqlService
brooklyn.config:
service-type: available_service #which was added to the platform
by a
broker
instance-name: instance_name #used to bind the instance
plan: plan_to_use #offers varying levels of resources or features
for
the same service
creationScriptUrl: script.sql #script to init the database
MySqlService is an entity which allows to create an instance of any
mysql service.
Then, Actually, all the services are created following the same
method,
a service
requires the service-type, the instance-name and the plan to be
created,
then it is
possible to create any service using a generic entity. However, it
looks
interesting
to create a entity for manage MySql services, because it will allow
concrete operations
to be carried out, for example, it allows the database, which is
created
by the service,
to be initialized using a script.sql.
Currently, users have to initialize the database manually after
creating
the service,
so this proposal would facilitate the management of the Cloud
Foundry
services.
Does it make sense for you? I will appreciate any advice and
suggestion
in order
to improve this idea.
Best,
Jose

Hi all,
Thanks Andrea for your report. As student I can say you are doing
a
great job as mentor, I am learning a lot about software
architectures,
patterns, and another principles to develop maintainable and
testable code.
I really appreciate that you spend a bit of time every day to direct
me in
the right direction.
During this time we decided to model a PaasLocation in Brooklyn
and to
target initially CF. Then we focus on understanding the CF features
and the
CF manifest which to model what I ended up calling
VanillaCloudFoundryApplication, which models a CF manifest and it is
startable on a PaasLocation. It was necessary a lot of iterations to
get
the current architecture. First, it was decided how the Cloud
Foundry
services had to be managed by the location (through a client), we
spend
quite time chatting and developing examples time reach an extensible
and
useful and testable architecture. Once the first prototype was
ready,
Andrea suggested to introduce the driver pattern, allowing the
entity to
delegate the location management to an driver, what it looks
interesting in
order to generalize our solution. Currently, we are updating the
Cloud
Foundry client that we are using to manage the Cloud Foundry
services, in
order to obtain a more maintainable code. Once this task will be
ready, I
will explore how to generalize this approach to support more
platforms
without refactoring too much the current solution.
Of course you can obtain a track and more concrete information
about
each of our task in our trello [1] board. A lot of aforementioned
decisions
can be also tracked following the open PR in [2].
Best,
Jose

Hi Andrea and all,
Thanks for that. I will try to review and to make some
contributions
to
the mentioned PRs. I have
to develop the proposal that I update to Google Summer of Code,
participate in the community,
develop the documentation, etc. (as Andrea has mentioned) but It
will
give
me great pleasure to
collaborate in different tasks, and functionality developments
:-)
Just a pair of questions about the proposal. I have a pair of
ideas
about
how PaaS entities could be added to
Brooklyn (in fact, I tried a pair of PRs) . The proposal that I
wrote
a
little description about that in the proposal
that I wrote, but I should develop some diagrams about necessary
entities,
locations and how it has to be added
to Brooklyn, then what should I do? should I write a Google
Docs?
should I
open a PR directly? I would prefer to
write a little document before coding. What do you think?
I was a little contributor in a different open project,
brooklyn-tosca. I
tried different examples in order to find new
possible functionalities there, but I was not actively involved
either in
the community chat or in the Mailing List.
I do not want to be a spammer. Probably my routine should be
different for
GSoC, I should ask more questions
about new functionalities and how they should be implemented
before
coding. Does the community use gitter?
In other words, I am still a novice here and I have much to
learn.
Hence,
I will appreciate any advice and suggestion
in order to improve my participation in the project.
Thanks a lot.
Best,
Jose

Community Bonding period is intended to get students ready to
start
contributing to your organization full time in May.
We encourage you to try to become familiar with the community
practices
and
processes: participate on Mailing Lists / IRC and ask
questions!
Set up their development environment: following
https://brooklyn.apache.org/v/latest/dev/index.html
Try to participate in code reviews for others. There is a
documentation
PR
open right now [1] or a small PR on brooklyn-server [2] you may
want
to
test to report your feedback or [3] in brooklyn-libray.
Ideally code review should become part of your daily routine,
but of
course, reading (and updating!) documentation and contributing
to
mailing
list / IRC will be appreciated as well.

I believe the next step is that you need a mentor in
the
Brooklyn
community. I know that Andrea Turli would be happy
to
volunteer
(I
just
spoke to him offline).
According to the timeline on
https://community.apache.org/gsoc.html
:

Can you therefore ensure that your application says you
have a
mentor, ideally updating it today? (I'm not sure
what the
process is
for
this).
