Overwriting apiKey in code

[EuroEager2008]

I want to configure the sink in appsettings.json, except for the apiKey (because of company policy and common sense). Thus I want to ovewrite the setting for apiKey during composition root. The replacement could be from Azure Key Vault or AWS Secrets Manager or similar and accessed in code before replacing. (The secret to access secrets manager is another story, but covered)

Is this possible? How? (Simple sample please) Thanks

Pulling this from my notes, but you should be able to do something like this:

var configuration = new ConfigurationBuilder()
    .SetBasePath(Directory.GetCurrentDirectory())
    .AddJsonFile(path: "appsettings.json", optional: false, reloadOnChange: true)
    .Build();

// Override the API key
configuration.GetSection("Serilog").GetSection("WriteTo").GetChildren().FirstOrDefault().GetSection("Args")["apiKey"] = "SOME_API_KEY";

// Override the API key (alternative) - same as above, but shorter
configuration["Serilog:WriteTo:1:Args:apiKey"] = "SOME_API_KEY";

Log.Logger = new LoggerConfiguration()
    .ReadFrom.Configuration(configuration)
    .CreateLogger();

Let me know if this works for you.

Thanks a lot, works great (if done just before WebApplicationBuilder.Build() is called)
