Kubernetes: The input does not contain any JSON tokens

[schwichti]

Hi,

I followed the steps described here https://simpleidserver.com/docs/installation/#kubernetes to deploy simpleidserver to Docker Desktop Kubernetes (not Minikube). When I try to access the URL https://website.sid.svc.cluster.local/master/clients I get an HTTP error 500. The log of the website shows these error messages:

The Docker compose solution https://simpleidserver.com/docs/installation/#docker works for me... What do I miss?

Hello,

There is indeed a mistake in the sid-kubernetes.yaml file. In the website-deploy service, set the property DefaultSecurityOptions__Issuer to https://idserver.sid.svc.cluster.local, and it should work.

[schwichti]

Can confirm that did the trick. Thanks.

What about the DefaultSecurityOptions__Issuer for the credentialissuerwebsite-deploy? See https://github.com/simpleidserver/SimpleIdServer/blob/master/sid-kubernetes.yaml#L401

[simpleidserver]

The value of DefaultSecurityOptions_Issuer for credentialissuerwebsite-deploy must remain unchanged and should follow this format: https://<URL>/master.

The difference between credentialissuerwebsite-deploy and website-deploy is that website-deploy supports realms and uses a custom version of the Microsoft.AspNetCore.Authentication.OpenIdConnect NuGet package.
