startDetection external script won't work in Cloudify 2.7.1

I can't arrive to use an axternal script for startDetection in Cloudify 2.7.1.

I try:

def result = ServiceUtils.isPortOccupied(port)
println "startDetection.groovy: is service started : ${result}"

return result

and the result is:

2014-09-25 12:46:09,268 default.service [1] INFO [org.cloudifysource.usm.launcher.DefaultProcessLauncher] - startDetection.groovy: isPortFree port ...
2014-09-25 12:46:09,300 default.service [1] INFO [org.cloudifysource.usm.launcher.DefaultProcessLauncher] - startDetection.groovy: is service started : false

2014-09-25 12:46:09,517 default.service [1] INFO [org.cloudifysource.usm.UniversalServiceManagerBean] - Process liveness test passed

before the real end of the start script.

And I try:

def result = ServiceUtils.isPortOccupied(port)
println "startDetection.groovy: is service started : ${result}"
if (result){
    System.exit(0)
}
System.exit(-1)

and the result before the end of the start script is:

and the result after the end of the start script is:

2014-09-25 12:46:09,268 default.service [1] INFO [org.cloudifysource.usm.launcher.DefaultProcessLauncher] - startDetection.groovy: isPortFree port ...

2014-09-25 12:46:09,517 default.service [1] INFO [org.cloudifysource.usm.UniversalServiceManagerBean] - Process liveness test passed

In both case it doesn't work.

I can only use the startDetection in closure like that:

startDetection {
    println "service.groovy(startDetection): isPortFree ${port} ..."
    return ServiceUtils.isPortOccupied(port)
}

like the stopDetection.

Someone know why?

Solution

  • The log entries you copied above seem ok. With start detection, if you use an external lifecycle script, all you can do is pass a process return code which indicates pass/fail. A zero return code indicates the test passed - start detection completed successfully. A non-zero value means the test did not pass.

    In your question, when the start script completed successfully, you get this: Process liveness test passed

    So the script finished correctly, start detection passed. What is it exactly that doesn't work?
