Possibly crazy idea about installable child instances
Geronimo needs some "special purpose" "little" servers related to the main one, for instance to run javaee app clients. I'm thinking of implementing this as a karaf child instance. I'm going to make a kar to install it (i.e. all the etc/ and such resource files will be in a kar under resources/instances/client/etc).
At the moment I'm thinking of just reusing most of the files from the main server and hand-editing them, but maybe it would be possible to combine things so that the server-assembly mojos generate something into the instances/<foo> directory and then the kar packaging step packs stuff into a kar.
I don't yet know if this makes sense... it would result in it being easy to make installable child instances with properties defined in the pom. Putting the idea out in case I forget about it :-)
thanks

Ahhh OK, catcha.
It's at build time and it's kind of "instance provisioning".
On the other hand, I plan to "store/package" a profile as a kar file,
and the profile is a diff on the "default" Karaf kar.

Hi JB,
That looks useful but I think it's for a different purpose. I want something maven sets up as part of the build, and I want the instance to be a fairly independent server. Basically I want the startup.properties for the instance to be generated from startup features in the same way it is for a karaf assembly, but in the instance directory, and then the instance files packed up as kar resources rather than packed up as a server assembly tar.gz and zip.
BTW installing an instance from a kar seems to work fine.... I made the resources for the kar (i.e. all the instance/<foo> files) by hand but once made you can include it in a karaf assembly and then it works fine.
thanks!

Hi David,
What do you think about something like:
karaf@root> instance:create geronimo-my
karaf@root> instance:connect geronimo-my
karaf@geronimo-my> profile:apply geronimo
Patching etc/org.apache.karaf.features.cfg file
Patching system directory
...
It's what I have with the profiles for now.
Regards
JB
