OAuth2 authentication is broken when using k8s with istio #17384

Open deepu105 opened 2 years ago

deepu105 commented 2 years ago

When creating a microservice stack with Oauth2 auth and deploying to istio on GKE, authentication to microservices ends up in an infinite loop. The gateway application and authentication for that works, but if you try to access an API provided by one of the microservice it will go on a loop. I was trying to get my standard e-commerce ms stack working with Keycloak and Okta and ended up here. Still trying to figure out whats going on. I don't see any authorization headers being passed around. But I don't see those headers for gateway APIs as well, for example the customer endpoint served by store. I'm not sure if its an Istio issue though, probably how auth is setup on JH app side.

I'll get back to debugging it after holidays, so in the meantime if anyone wants to give it a shot please go ahead

I experienced the same issue today. I managed to get authorisation to work I think by editing the gateway virtual service. For some reason looks like calls are being made to /service/api/api so adding the extra api to the virtual service kind of stopped the authorisation issue but I am experiencing other issues where entities are not being returned.

I recall seen this and created this branch https://github.com/jhipster/generator-jhipster/pull/17388, but it needs more testing. The expired token is ignored at the gateway side, but not at the microservice side, creating this infinite loop.

deepu105 commented 2 years ago

You are too fast Marcelo ❤️ I'll do some tests with your branch and let you know

I tested your branch but the looping issue is still present at least with Istio + k8s

mshima commented 2 years ago

The PR was from a previous problem I found. Not actively working on this right now.

deepu105 commented 2 years ago

no worries

deepu105 commented 2 years ago

for some more context, normal microservices with reactive gateway works fine with OAuth, its only with Istio there is issue.

taoyonggang commented 2 years ago

This bug isn't fixed at latest version.

taoyonggang commented 2 years ago

The right solution is removing the auth fuction from code .And then add OPA config with Istio.

Ref: https://istio.io/latest/blog/2021/better-external-authz/ https://medium.com/google-cloud/external-authorization-server-with-istio-1159b21682bb

deepu105 commented 2 years ago

Probably, but the gateway is able to login with OAuth and microservices hence should be able to auth using JWT so maybe configuring OPA for that could work without removing auth

Thanks & Regards, Deepu

Hey @xetys could use some of your expertise here if you have time

@ohmex do share what you learned. Maybe I missed something during my debugging
