Allow OIDC usage over http #88541

Open knechtionscoding opened 2 years ago

knechtionscoding commented 2 years ago

Description

Background

Elasticsearch requires TLS connections in order to enable some security feature like Tokens for OIDC. This is important to guarantee that sensitive information is properly protected.

However, there are scenarios where encryption is managed outside of Elasticsearch. Notable examples are service mesh or reverse proxy software that are in front of the cluster, handling all incoming communication with the REST endpoint.

Description

Goal

Allow service mesh and reverse proxy environments to use Elasticsearch OIDC/Tokens in scenarios where a clear-text connection between the service and Elasticsearch is used.

Proposal

Allow to relax the TLS bootstrap checks to make OIDC/Tokens available when TLS is not enabled.

This is a duplicate of https://github.com/elastic/elasticsearch/issues/81817. But I am going to close #81817 since this issue here is just for OAuth2 tokens while the other one has a mix of tokens and API keys and API keys no longer have the TLS restriction.

Yes this would be very useful - I can't currently use Entra via OpenId Connect where the cluster is in kubernetes behind an haproxy which is TLS terminated. The pods inside the cluster are running just http so we don't have to deal with assigning certs for termination.

This is an issue.

Is there any progress on that? @elasticsearchmachine
