How do I configure Serilog for multiple Environments appsettings.json

Question

I am trying to configure appsettings.json so that I have multiple Serilog variables for each of our environments(Dev, UAT, Prod etc) I have the following serilog that works for dev:

    "Serilog": {
  "MinimumLevel": "Verbose",
  "Using": [
    "Serilog.Sinks.Console",
    "Serilog.Sinks.Seq"
  ],
  "WriteTo": [
    {
      "Name": "Console"
    },
    {
      "Name": "Seq",
      "Args": {
        "serverUrl": "https://seq-dev.test.com"
      },
      "Properties": {
        "Application": "Console.Sample",
        "Environment": "Local"
      }
    }
  ]
},

My current solution is to have an array of Serilog instance. I am going to be passing an arg into main specificying which environment I want and I should use that Seq instance(Example: args: Environment="d" for dev - this should pull the dev Serilog)

    "d": {
  "Serilog": {
    "MinimumLevel": "Verbose",
    "Using": [
      "Serilog.Sinks.Console",
      "Serilog.Sinks.Seq"
    ],
    "WriteTo": [
      {
        "Name": "Console"
      },
      {
        "Name": "Seq",
        "Args": {
          "serverUrl": "https://seq-dev.test.com"
        },
        "Properties": {
          "Application": "Console.Sample",
          "Environment": "Local"
        }
      }
    ]
  }
},
"q": {
  "Serilog": {
    "MinimumLevel": "Verbose",
    "Using": [
      "Serilog.Sinks.Console",
      "Serilog.Sinks.Seq"
    ],
    "WriteTo": [
      {
        "Name": "Console"
      },
      {
        "Name": "Seq",
        "Args": {
          "serverUrl": "https://seq-dev.test.com"
        },
        "Properties": {
          "Application": "Console.Sample",
          "Environment": "Local"
        }
      }
    ]
  }
},

This is more of a configuration thing.

You need to specify a appsettings json for each environment

The one that will be used by the application is determine by this ENV variable

Thank you Paul for the quick answer! This is more of a utility app and will basically ping each environment at any time based off the command line args provided. Its not like this will be hosted in a dev environment and it will only hit dev. Therefor I am not sure Environment Variables are the right solution. Is there a way to set environment variables based off command line args? Or specify which app settings.json to use via command line "dev", "prod" ect? Thanks in advanced – cpage Sep 02 '21 at 20:08
Is this a asp.net core app? or a console .net core app? In any case both would have a section of code that handles the reading of the appsettings.json. I would think you just set your variable logic there – Paul Lorica Sep 02 '21 at 20:41
