Authenticating Vyne to other services

Configuring authentication credentials Vyne provides to other services


Vyne will pass authentication headers to upstream services when sending requests.

Configuration is either through the UI, or by a file stored on the Vyne server.

File based configuration

Vyne will read / write authentication settings from a file on the vyne server.

The location of the file is configurable by setting vyne.auth.config-file setting, and defaults to ./auth.conf.

Vyne uses a HOCON format for it's config files. (HOCON is a superset of JSON, so JSON is also valid.)

Here's a sample config:

authenticationTokens {
   "com.acme.MyService" { // The fully qualified name of a service, as defined in a taxi schema.  Should be surrounded in quotes.
      tokenType = AuthorizationBearerHeader // Only `AuthorizationBearerHeader` is supported at present
      value = "Hello, World"
   }
}

Authentication token types

At present, only AuthorizationBearerHeader is supported, however we plan on expanding support as required.

Authorization Bearer tokens

Setting the tokenType to AuthorizationBearerHeader will add a header of Authorization: Bearer ${tokenValue} to outbound requests.

Using environment variables

Environment variables can be used in authentication config files.

authenticationTokens {
   "com.acme.MyService" {
      tokenType = AuthorizationBearerHeader
      value = ${foo} // The enviroment variable of 'foo' is read and substituted
   }
}

Other configuration approaches

Authentication configuration is always persisted to the file described above. However, there are ways of adding / removing to the configuration without requiring file access.

UI configuration

Authentication tokens can be added, modified and deleted through the UI, via the Authentication Manager.

Changes made here are persisted in the configured authentication file.

REST API

Authentication tokens can be added, modified and deleted through the REST API:

Create or update token

POST to /api/tokens/service/{serviceName}:

{
   "tokenType" : "AuthorizationBearerHeader",
   "value" : "yourAPIToken"
}

Deleting a token

Deletes a token

DELETE to /api/tokens/service/{serviceName}

Listing configured tokens

It is possible to list the configured tokens. However, the token values are not returned.

GET to /api/tokens

[ { "serviceName" : "com.foo.MyService", "tokenType" : "AuthorizationBearerHeader" } ]
