This document explains how to configure Dex as an OIDC provider (check general information and pre-requisites for using an OAuth2/OIDC Provider with Kubeapps).
For Dex, you can find the parameters that you need to set in the configuration (a ConfigMap if Dex is deployed within the cluster) that the server reads the configuration from. Note that since Dex is only a connector you need to configure it with some third-party credentials that may be a client-id and client-secret as well. Don't confuse those credentials with the ones of the application that you can find under the staticClients section.
- Client-ID: Static client ID.
- Client-secret: Static client secret.
- OIDC Issuer URL: Dex URL (i.e. https://dex.example.com:32000).
