Fine-Grained Security Permissions In Bundle Provisioning

RHQ allows one to bundle up content and provision that bundle to remote machines managed by RHQ Agents. This is what we call the "Bundle" subsystem, the documentation actually titles it the "Provisioning" subsystem. I've blogged about it here and here if you want to read more about it.

RHQ 4.9 has just been released and with it comes a new feature in the Bundle subsystem. RHQ can now allow your admins to give users fine-grained security constraints around the Bundle subsystem.

In the older RHQ versions, it was an all-or-nothing prospect - a user either could do nothing with respect to bundles or could do everything.

Now, users can be granted certain permissions surrounding bundle functionality. For example, a user could be given the permission to create and delete bundles, but that user could be denied permission to deploy those bundles anywhere. A user could be restriced in such a way to allow him to deploy bundles only to a certain group of resources but not others.

Along with the new permissions, RHQ has now introduced the concept of "bundle groups." Now you can organize your bundles into separate groups, while providing security constraints around those bundles so only a select set of users can access, manipulate, and deploy bundles in certain bundle groups.

If you want all the gory details, you can read the wiki documentation on this new security model for bundles.

I put together a quick, 15-minute demo that illustrates this fine-grained security model. It demonstrates the use of the bundle permissions to implement a typical use-case that demarcates workflows to provision different applications to different environments:

Watch the demo to see how this can be done. The demo will illustrate how the user "HR Developer" will only be allowed to create bundles and put them in the "HR Applications" bundle group and the user "HR Deployer" will only be allowed to deploy those "HR Applications" bundles to the "HR Environment" resource group.

Again, read the wiki for more information. The RHQ 4.9 release notes also has information you'll want to read about this.
