Use GDMAWe have not changed the open nature of GDMA. It is still all laid out in a clear file structure that is familiar to those used to working with GroundWork servers and agents. You should use it to make the most of GroundWork.
Don't add your own plugins to the serverInstead, use GDMA (even on the GroundWork server itself). This ensures your server can be easily upgraded when new versions come out. We expect to put out several each year from now on, and upgrades will be nearly seamless.
Don't stop some of the containersYou might think it doesn't matter that some of the containers are not running, and be tempted to stop them to save on CPU or RAM. This isn't a good idea - pretty much all the containers are there for good reason, and there's a lot of inter-dependency. If you are having resource constraints, please let us know by submitting a support request in GroundWork Support, and we'll help you tune the system as needed. In general, however, you may find that you need more disk and RAM than you did in GroundWork 7.x to work properly, please see the System Requirements page for details.
