Similar to my Cloud Foundry environment notes<\/a> 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.<\/p>\n

Deploying the app<\/h2>\n

Still using the same test code <\/a><\/p>\n

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<\/p>\n

mkdir build\ncd build\nunzip ..\/target\/simple-executable-jar-web-server-0.0.1.jar\ncd ..\nstackato push --path \/xdata\/local\/dev\/markus\/git\/simple-executable-jar-web-server\/build\n<\/code><\/pre>\n
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<\/p>\n
stackato passwd\n<\/code><\/pre>\n
and it accepted my old password. Besides Firefox remembered the same password.<\/p>\n
A server restart helped. Since I usually only pause my VMs it might have gotten confused.,<\/p>\n

Adding services<\/h2>\n
Wanted to add the service via the web UI but did not immediately see how.<\/p>\n
stackato create-service mysql testdb simple-executable-jar-web-server<\/p>\n
Afterwards the following new environment properties were added :<\/p>\n

Appendix : How to Not Set Environment<\/h2>\n
Not sure how this should have worked, but it didn’t for me…<\/p>\n
I wanted to set Java System Properties to pass in the server.address and server.port. The same worked for Cloud Foundry<\/a><\/p>\n
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’<\/p>\n
