How to automate local DNS entries per project? (feddit.de)

In many projects, you might have custom DNS entries, for example for your development environment, or because something is prototype without a real DNS entry yet, or simply for convenience to not remember weird IP addresses.

Currently, these special domains might be used in the configuration of a project (say, the DB server is db1.acme.local), and that's version controlled and everything, but creating the actual DNS entry (in the hosts file for example) is still manual and therefore error prone.

Has anyone figured out a nice solution to this? Or do you all have super quick IT departments that'll give you real domains instantly?^^

You could use a script to automate editing the hostfile on windows or /etc/hosts on Linux. If you define a section in the file with comments, the script should just replace the relevant entries for the project inside the section, and leave the rest alone. You can have multiple sections and multiple scripts that can coexist. Works well for my work project. It's included in a general setup script which can be run as often as needed to keep stuff like this updated on our local machines.
