Directory structure

The directory layout of a Karaf installation is as follows:

  • /bin: control scripts to start, stop, login, …​

  • /etc: configuration files

  • /data: working directory

    • /cache: OSGi framework bundle cache

    • /generated-bundles: temporary folder used by the deployers

    • /log: log files

  • /deploy: hot deploy directory

  • /instances: directory containing [instances|instances]

  • /lib: contains the bootstrap libraries

    • /lib/ext: directory for JRE extensions

    • /lib/endorsed: directory for endorsed libraries

  • /system: OSGi bundles repository, laid out as a Maven 2 repository

The `data` folder contains all the working and temporary files for Karaf.
If you want to restart from a clean state, you can wipe out this directory, which has the same effect as
link:start-stop[using the clean option].
