JBPM 6 Virtual File System - where are the files actually stored?

badtea Sep 30, 2014 4:05 PM

I know that JBPM 6 has a Virtual File System (VFS) for storing knowledge definitions created in the KIE workbench. (See this blog post).

The files in the VFS must be stored somewhere on the local disk, right? Where are they stored?

For background: I am trying to run JBPM in a Docker container. Docker containers have volatile storage, so every time I restart the container I lose any processes I added while the container was running. I can force Docker to persist certain directories, but I have to know which directories. And I cannot find where my bpmn2 files are actually stored on my server.

For example, if the VFS were "effectively" stored under /usr/local/jbpm, then I would make Docker persist everything under /usr/local/jbpm.

Thanks!

files are stored in git repository that is under .niogit folder. If not configured differently it will be in current directory although it might be reconfigured via system properties. So there are three important location that you should set to preserve them across container restarts:
org.uberfire.nio.git.dir
org.uberfire.metadata.index.dir
org.guvnor.m2repo.dir

Thanks swiderski.maciej!

I created a simple BPMN process with a script task that outputted those three properties you mentioned. All the properties were printed as null. Does that mean they are simply set to the defaults that are listed on the documentation page? I looked through the filesystem, and it does look like they are being stored in the default locations.

So I could either persist those three directories, or simply persist the entire "jbpm-installer" directory. I will have to decide the best approach and try this later today.

Thanks again!

correct, if the properties are not set then defaults apply. Personally for real deployments (e.g. production) I'd go for defining locations for these folders via properties, easier to move installation around while keeping same storage.

Thanks swiderski.maciej! I'm using the defaults now to get it working, but I'm probably going to use the system properties in the future. Anyway, I preserved those three folders that you mentioned, and now my business processes are persisted across container restarts.
