API_KEY argument

[nbroad1881]

Feature request

TEI has the API_KEY argument:

   --api-key <API_KEY>
      Set an api key for request authorization.

      By default the server responds to every request. With an api key set, the requests must have the Authorization header set with the api key as Bearer token.

      [env: API_KEY=]

It would be nice if TGI had this as well.

Motivation

It enables custom authorization of the endpoint.

Adding this block in here and appending the layer should achieve this.

One negative effect of this is that the healthcheck and info endpoints get auth included.

I would propose having a slightly different approach to TEI and only adding the Auth Layer at the route level for non information endpoints. I could start a PR for this next week.
