This is demo how to use forwardauth middleware of traefik. You can find more details about it on official traefik docs

How to use it (in k8s)?

3. create a deploy and make sure that you override these environment variables:

• JwtSigningKey="-- required: put your signing key --"
• AzureAD__GroupId="-- optional: put id of group to restrict list of users that have access --"
• AzureAD__ClientId="{clientId}"
• AzureAD__ClientSecret="{clientSecret}"
• AzureAD__AuthorizeEndpoint="https://login.microsoftonline.com/{tenantid}/oauth2/v2.0/authorize"
• AzureAD__TokenEndpoint="https://login.microsoftonline.com/{tenantid}/oauth2/v2.0/token"

4. create a service for the deploy
5. create a traefik middleware object:

apiVersion: traefik.containo.us/v1alpha1
kind: Middleware
metadata:
  name: auth
spec:
  forwardAuth:
    address: http://{service name or ip}/auth
    trustForwardHeader: true
