Local development DNS simulation

Local development DNS simulation is a technique used to resolve custom domain names to the local machine (typically 127.0.0.1 or localhost). This is often required when running multiple services locally that need to communicate via specific domain names rather than ports, such as distinguishing between a web server and a database server, or simulating a production environment.^[400-devops__10-Version-Control__README.md]

Implementation via Hosts File

The most common method for simulating this behavior locally is by modifying the system's hosts file.^[400-devops__10-Version-Control__README.md]

On Unix-like systems (Linux and macOS), this file is located at /etc/hosts.^[400-devops__10-Version-Control__README.md]

On Windows, the file is found at C:\Windows\System32\drivers\etc\hosts.^[400-devops__10-Version-Control__README.md]

Configuration Example

To map specific domains to the local environment, entries are added to the hosts file in the format IP-Address hostname.^[400-devops__10-Version-Control__README.md]

For example, to resolve drone-server and gitea-server to the local loopback interface, the following configuration would be added:

127.0.0.1 drone-server
127.0.0.1 gitea-server
