how to create Apache brooklyn blueprint using entity
HI,
I am trying to create an application from available entities from Apache
Brooklyn. My blueprint is :
name: Tomcat3 location: jclouds:.... services: - type:
brooklyn.entity.webapp.tomcat.TomcatServer name: tomcat
provisioning.properties: minRam: 1024mb minCores: 2 minDisk: 1024
extraSshPublicKeyUrls: - https://.............../file.pub
This creates an instance with Tomcat and the status shows as 'Running' and
the service status is up . But when I connect to the URL of the tomcat
application I cannot see Tomcat running there . What am I missing here ?
Can anybody help me with this ?
Thanks,

Hi,
For most entity types (i.e. types of things to be deployed), there are
no mandatory keys. It will do a standard deploy (or at least one of the
standard ways of deploying - some software defines multiple ways).
For things like Tomcat and JBoss app-server, it will not deploy a WAR
unless you tell it to. You can either supply WARs as config at start
time, or you can subsequently call the deploy effector.
---
To say where it should be deployed (i.e. which cloud/machine), you will
need to specify a location and configuration for that location (e.g.
influencing the machine size, image, etc).
---
If using chef, there is more configuration that needs to be supplied:
for example, you need to specify the chef recipes and attributes.
You'd normally define this once (e.g. to say what is needed to deploy
MySQL) and then add that blueprint definition to the catalog.
Subsequently, people can reference your blueprint using its type name,
and thus deploy that entity type without having to supply any additional
configuration.
---
For logging onto the box and looking at the processes / services, it
depends on the entity for how it was installed. The definitive source of
information is to look at the code behind a given entity to see what
install/launch commands it executes.
For normal usage, you don't need to look at the code - looking at the
sensors (i.e. attributes) should give you all the connection details
that one normally requires to use it.

Hi,
Thanks for the references. I
I tried a similar blueprint for RabbitMQ entity . The deployment is
successful and the service status says 'running' but when I ssh into the
instance and try to check status of rabbitmq-server , it says '
rabbitmq-server not installed '. I can find that rabbitmq-broker is
downloaded into install.dir .
In cases like this , should we explicitly mention a command to install the
service ? if not then how do I check the rabbitmq installation ?
(Assuming that the management plugin is not part of entity and hence
management UI will not be accessible )
In short , my question is , what are the mandatory 'config keys' that needs
to be provided for a entity to launch successfully ?
Thanks,

Hi,
The configuration options are listed at [1].
You can create a dependency on another entity by setting a config value
using the "attributeWhenReady" approach, see [2].
Entity install: correct, the machine where Tomcat is being set up will
download and install it.

Hi ,
Thanks for your time .
Yes, I was able to reach tomcat after adding the wars.root. I was assuming
that without the war file , I should have access to tomcat's home page but
that was not the case.
How do we know the dependencies/ configurations for other entities ? Can
you suggest me link to the documentation/sample blueprints created using
entities ?
And when we use an entity like the way I have mentioned above, Does it mean
that the entity is downloaded and installed (service is brought up) ?
Thanks,

Hi,
When you say "I cannot see Tomcat running", do you mean that it fails to
connect (e.g. host or port not reachable), or gives a 404, or the page
looks blank?
I believe the page can look blank in your browser if no root WAR has
been deployed. You can check the return code etc with something like:
curl -sL -w "%{http_code} %{url_effective}\n" http://myhostname:8080
If Tomcat is reachable but with no war, then try adding the line below
to the config:
wars.root:
http://search.maven.org/remotecontent?filepath=io/brooklyn/example/brooklyn-example-hello-world-sql-webapp/0.6.0/brooklyn-example-hello-world-sql-webapp-0.6.0.war
e.g.
name: Tomcat3
location: jclouds:....
services:
- type: brooklyn.entity.webapp.tomcat.TomcatServer
name: tomcat
wars.root:
http://search.maven.org/remotecontent?filepath=io/brooklyn/example/brooklyn-example-hello-world-sql-webapp/0.6.0/brooklyn-example-hello-world-sql-webapp-0.6.0.war
provisioning.properties:
minRam: 1024mb
minCores: 2
minDisk: 1024
