Please describe the current behavior?

Not possible to set api keys from appsettings.json.
Today it has to be done from code

.UseSerilog(
    (context, services, configuration) =>
    {
        configuration.WriteTo.Elasticsearch(
            new ElasticsearchSinkOptions(new Uri("..."))
            {
                ModifyConnectionSettings = (x) =>
                    x.ApiKeyAuthentication(new ApiKeyAuthenticationCredentials("my api key"))
            }
        );
    }
)

Please describe the expected behavior?

It would be handy if we could configure authentication like api keys from appsettings.json

Something like

{
  "Serilog": {
    "Using": ["Serilog.Sinks.Elasticsearch"],
    "WriteTo": {
      "ElasticsearchSink": {
        "Name": "Elasticsearch",
        "Args": {
          "nodeUris": "...",
          "apiKey": "my api key"
        }
      }
    }
  }
}

Hi,

you can use like this

{
    "Name": "Elasticsearch",
    "Args": {
        "nodeUris": "https://.............../;",
        "connectionGlobalHeaders": "Authorization=Basic {XXX}",
    }
}

where {XXX} is {username}:{password} in base64 format

[snebjorn]

Thanks for the suggestion. However {username}:{password} is different from an API key.

[TiemenSET]

when is this going to be implemented?

[mivano]

When somebody submits a PR for this functionality. Alternatively, look at the sink Elastic itself offers if this is a better match. You can find a link in the readme.

Didn't test it, but from looking at the official API key documentation, it looks like this might work:

        "connectionGlobalHeaders": "Authorization=ApiKey {XXX}",

Where XXX is the base64 encoded API key.
