Apache Brooklyn#

Intro#

Use (yaml) blueprints to model your application (components) and describe the required infrastructure. But also deploy your app and manage (monitor) your application.

There is a Catalog with components to choose from, or write your own.

It has a nice web ui, but also everything available via REST interfaces.

• sample brooklyn.properties

Installation#

Well, that is very easy:

• download tarball from https://brooklyn.incubator.apache.org/download/index.html

tar -zxf brooklyn-0.7.0-incubating-dist.tar.gz
cd brooklyn-0.7.0-incubating
bin/brooklyn launch

It will log to 2 files in the current directory brooklyn.info.log brooklyn.debug.log. If you have not created a ~/.brooklyn/brooklyn.properties file with special settings, you will get anonymous admin access at http://localhost:8081, but only if you come from localhost. If you come from other hosts (like when you run it in a docker container then you get basic auth), the password is generated each time the server is started and is logged to the brooklyn.info.log file:

2015-08-08 19:12:56,404 INFO  b.r.s.p.BrooklynUserWithRandomPasswordSecurityProvider [brooklyn-jetty-server-8081-qtp1042232199-22]: Allowing access to web console from localhost or with brooklyn:m01u2ll1H2

I decided to run it in a Docker container, the Dockerfile and other stuff are in my private my gitblit.

I also have a Docker container for brooklyn nodes (so we can get very predictable targets for brooklyn).

Both Dockerfiles are "subclassed" from phusion/baseimage.

Using#

Get Started on localhost#

I first followed the get started and the deploying a blueprint, which deploys a MySQL DB, a Tomcat7 server and an nginx frontending webserver, all to localhost.

This went well, but make sure that the user brooklyn can ssh to localhost with pub/priv key, no password and no password phrase, and that this user can sudo su - to do all the necessary stuff (the main reason to run it in a Docker container).

So this went rather smooth, note that in the above example you can run all components (MySQL, Tomcat, nginx) on the same target (location), namely localhost.
