SQL/XML Dumps/Becoming a dumps co-maintainer/Deployment-prep

We do a lot of testing in the Deployment-prep project in the Wikimedia Cloud. You'll want to know how to set up a new snapshot server instance there, how to access it once it's ready, and how to run tests.

Setting up a new snapshot instance
All of our dumps are produced by servers named snapshotNNN and written out to NFS fileshares on hosts named dumpsdataNNN, except in the deployment-prep project. There, we have a single instance that has a local filesystem mounted where the NFS filesystem would usually go, and reads and writes are done directly to it. This means that certain features such as NFS locking are not testable there, but everything else is.

So, to set up a new testbed, we need only one instance, a new "deployment-snapshot0x" where x is the next available number. Currently we are on 03.

You will want the following settings when setting up an instance :
 * image type: g2.cores4.ram8.disk80 (should have: VCPUs: 4, RAM: 8GB, Disk: 80GB)
 * hostname: deployment-snapshotXX
 * OS: currently buster, change as needed
 * Security group: default
 * Sever group: ignore this

Once you click "Launch Instance", the instance will be configured, create and booted. Don't expect it to come up with everything working. Instead:
