Etcd.Microsoft.Extensions.Configuration

Etcd-based configuration provider for Microsoft.Extensions.Configuration.

Keep in mind that starting from v2, it will work only under Windows 10 or Windows Server 2016 (or later) because the internal gRPC client uses the HTTP/2 protocol for communication (https://docs.microsoft.com/en-us/answers/questions/310032/2012-r2-net-core-http2.html).

Quick Start

HTTP

var config = new ConfigurationBuilder()
  .AddEtcd(
    new Credentials("MyEtcdUserName", "passw"),
    new EtcdSettings("http://serveraddress:2379"))
  .Build();

var mySection = config.GetSection("MySection");
var myKeyValue = mySection["MyKeyName"];

HTTPS

When using HTTPS, a *.crt CA certificate (provided by the etcd administrator) should be placed in a well-known system certificate store (depending on the OS).

• For Windows, it is Trusted Root Certification Authority.
• For Linux, at least for Arch/Manjaro Linux, it should be placed in /etc/ca-certificates/trust-source/anchors/, followed by the sudo trust extract-compat command.

HTTPS with Settings from a Local JSON File

appsettings.json

{
  "EtcdSettings": {
    "ConnectionString": "https://serveraddress:2379"
  }
}

var jsonConfig = new ConfigurationBuilder()
  .AddJsonFile("appsettings.json")
  .Build();

var config = new ConfigurationBuilder()
  .AddEtcd(
    new Credentials("MyEtcdUserName", "passw"),
    new ConfigurationBasedEtcdSettings(jsonConfig))
  .Build();

var mySection = config.GetSection("MySection");
var myKeyValue = mySection["MyKeyName"];

Settings can be mixed from different locations.
