Debug groovy script within a container
I'm building a jenkins container and want to set the KeycloakSecurityRealm in the initial flow. I already have a script which works fine for default settings:
import hudson.*
import hudson.model.*
import jenkins.*
import jenkins.model.*
import java.util.logging.Logger
import hudson.security.*
import java.util.*
import com.michelin.cio.hudson.plugins.rolestrategy.*
import java.lang.reflect.*
import org.jenkinsci.plugins
/*
NOTE: that megascript should be split someday, when my groovy skills improves.
*/
Thread.start {
//vbles definition
def logger = Logger.getLogger("")
def instance = Jenkins.getInstance()
def pm = instance.getPluginManager()
def uc = instance.getUpdateCenter()
def installed = false
// More code...
//No plugins to update. Security can be set
logger.info("All plugins are up to date")
logger.info("Setting security")
// logger.info("Creating initial user")
// hudsonRealm.createAccount("USER","USER")
logger.info("Creating reaml")
def keycloakSecurityRealm = keycloakRealm.createSecurityComponents()
//realm based on jenkins database
logger.info("Setting Security realm to KEYCLOAK")
instance.setSecurityRealm(keycloakSecurityRealm)
//not anonymous read allowed
This code crashes without any information. I whould like to debug the container so I've checked I can run the step where the container crashes to attach an interactive console:
Can do
docker run -ti 3ed
And I have access to the container as root.
Problem is I can't debug the script. I've checked there are some ways as using jdb but in all cases it is neccessary a mail java class for running it. The original script worked when called without changes so it runs file without any classes.
How could I debug this kind of java scripts inside a container?
Thanks.

Once inside container, make sure to run your code in debug mode.
java -agentlib:jdwp=transport=dt_socket,server=y,suspend=y,address=32887 ...
In case you have no chance to start java by yourself, you can always use _JAVA_OPTIONS
export _JAVA_OPTIONS=-agentlib:jdwp=transport=dt_socket,server=y,suspend=y,address=32887
Attach your debugger (e.g. IntelliJ) to remote machine (your Docker based container). Debug the code from the IDE started outside the container.
It should do the trick.
For a sample (used for profiling) take a look here:

It's not the same thing, but it's similar in a sense that Docker based code (Java) is executed inside container, while profiler (running outside container) is attached to remote machine.
