Similar to my Cloud Foundry environment notes I was interested what Stackato puts on top of the Cloud Foundry framework. This was running in a local VM that I downloaded from their site.

Deploying the app

Still using the same test code

After spending quite some time on trying to set the JAVA_OPTS, I instead changed the source code to use the environment variable instead of server.port and server.address and then re-pushed

mkdir build
cd build
unzip ../target/simple-executable-jar-web-server-0.0.1.jar
cd ..
stackato push --path /xdata/local/dev/markus/git/simple-executable-jar-web-server/build

The app worked after my code changes and the test server was up and running, but I could not log into the web console, anymore, thought I had the password wrong, but then used

stackato passwd

and it accepted my old password. Besides Firefox remembered the same password.

A server restart helped. Since I usually only pause my VMs it might have gotten confused.,

Adding services

Wanted to add the service via the web UI but did not immediately see how.

stackato create-service mysql testdb simple-executable-jar-web-server

Afterwards the following new environment properties were added :

> 'DATABASE_URL' = 'mysql://ucLE9lXtowAqf:pYSRyL7jO1vgi@172.16.127.133:3306/d415c91f5251b450d9a3c20c45b5d7777'
> 'JDBC_MYSQL_URL' = 'jdbc:mysql://ucLE9lXtowAqf:pYSRyL7jO1vgi@172.16.127.133:3306/d415c91f5251b450d9a3c20c45b5d7777'
> 'MYSQL_URL' = 'mysql://ucLE9lXtowAqf:pYSRyL7jO1vgi@172.16.127.133:3306/d415c91f5251b450d9a3c20c45b5d7777'

And these changed : < ‘STACKATO_SERVICES’ = ‘{}’ —

‘STACKATO_SERVICES’ = ‘{“testdb”:{“name”:”d415c91f5251b450d9a3c20c45b5d7777″, “hostname”:”172.16.127.133″,”host”:”172.16.127.133″,”port”:3306, “user”:”ucLE9lXtowAqf”,”username”:”ucLE9lXtowAqf”,”password”:”pYSRyL7jO1vgi”, “uri”:”mysql://ucLE9lXtowAqf:pYSRyL7jO1vgi@172.16.127.133:3306/d415c91f5251b450d9a3c20c45b5d7777″, “jdbcUrl”:”jdbc:mysql://ucLE9lXtowAqf:pYSRyL7jO1vgi@172.16.127.133:3306/d415c91f5251b450d9a3c20c45b5d7777″}}’

< 'VCAP_SERVICES' = '{}'
---
> 'VCAP_SERVICES' = '{"mysql":[{"name":"testdb","label":"mysql-5.5","tags":[],
    "plan":"free","credentials":{"name":"d415c91f5251b450d9a3c20c45b5d7777",

VCAP_APPLICATION seemed to change like for CloudFoundry – but unrelated to to service.

and this system proeprty changed, simialr to Cloud Foundry:

< 'java.class.path' = '/home/stackato/app/.'
---
> 'java.class.path' = '/home/stackato/app/.:/home/stackato/app/.java-buildpack/maria_db_jdbc/maria_db_jdbc-1.1.7.jar'

Appendix : How to Not Set Environment

Not sure how this should have worked, but it didn’t for me…

I wanted to set Java System Properties to pass in the server.address and server.port. The same worked for Cloud Foundry

Tried to figure out the right amount of escaping … this is what we want to see: ‘JAVA_OPTS’ = ‘-Dserver.port=$VCAP_APP_PORT -Dserver.address=$VCAP_APP_HOST’

stackato set-env simple-executable-jar-web-server JAVA_OPTS "-Dserver.port=\\\$VCAP_APP_PORT -Dserver.address=\\\$VCAP_APP_HOST"
Unknown option -Dserver.port

stackato set-env simple-executable-jar-web-server JAVA_OPTS '-Dserver.port=$VCAP_APP_PORT -Dserver.address=$VCAP_APP_HOST'
Unknown option -Dserver.port

giving up. I use the way it works descibed at http://community.activestate.com/node/9487 (or I could use cf).

vi build/stackato.yml

but no JAVA_OPTS and no system properties

stackato env-del simple-executable-jar-web-server JAVA_OPTS

Setting env variable 'JAVA_OPTS' to '-Dserver.port=\$VCAP_APP_PORT -Dserver.address=\$VCAP_APP_HOST' for app simple-executable-jar-web-server in org mnm.at / space demos as admin...
OK
TIP: Use 'cf push' to ensure your env variable changes take effect

rm build/stackato.yml 
stackato push --path /xdata/local/dev/markus/git/simple-executable-jar-web-server/build

even though this time the JAVA_OPTS variable looks right:

app[stdout.0]:    'JAVA_OPTS' = '-Dserver.port=$VCAP_APP_PORT -Dserver.address=$VCAP_APP_HOST'

there is not server.port system property. so it seems that the build back is different (though it is the java build pack)
