Backend nodes configuration

Host and ports​

Backend node applications expose a self-hosted HTTP API. The host address and port of those API's can be configured in a few ways.

Environment variable​

Host and port can be set by using the environment variables ASPNETCORE_URLS or URLS. For example:

ASPNETCORE_URLS="http://localhost:5001;https://localhost:5002"

Note: This approach is dedicated when each application is hosted in an isolated container like Docker containers.

Setting file​

Each application host and port can be also set by Urls property defined in the root level in appSettings.json file. For example:

{
    "Urls": "http://localhost:5001;https://localhost:5002"
}

Command line argument​

Set the host and port with the --urls parameter when running from the command line. For example:

.\Meniga.TriggeringEngine.exe --urls "http://localhost:5001;https://localhost:5002"

Configuration sources priority​

The priority of configuration is as followed:

  • ASPNETCORE_URLS environment variable
  • configuration files like appSettings.json
  • URLS environment variable
  • command line arguments

Each configuration source down the list overrides a variable from the previous source.
