Serilog + serilog-sinks-elasticsearch +ElasticSearch Auth

I struggled to find a good solution for this too. Adding the username/password to the url definitely does work but somehow doesnt feel right.

This worked for me:

.WriteTo.Elasticsearch(new ElasticsearchSinkOptions(new Uri("https://your-deployment.westeurope.azure.elastic-cloud.com:9243")){  ...,  ModifyConnectionSettings = x => x.BasicAuthentication("elastic", "your-password"),})

Good question....

You might try supplying them as part of the Elasticsearch server/stack URL.

Example:

.WriteTo.Sink(new ElasticsearchSink(new ElasticsearchSinkOptions(new Uri(url)){    AutoRegisterTemplate = true}

where

url = "https://user:password@stack-server:port"

If you want to stick with your configuration file (appsettings.json), knowing that you can use the argument connectionGlobalHeaders to specify the login/password, because Elasticsearch use Basic Authentication to authenticate the user.

Something like this:

"Serilog": {    "WriteTo": [      {        "Name": "Elasticsearch",        "Args": {          "nodeUris": "https://your-uri",          "connectionGlobalHeaders": "Authorization=Basic dXNlcm5hbWU6cGFzc3dvcmQ=",          "indexFormat": "application-log-{0:yyyy.MM}",          "autoRegisterTemplate": true,          "autoRegisterTemplateVersion": "ESv7"        }      }    ]  }

where the part after "Authorization=Basic" is the Base64 string of your "login:password".
