Create a new ingress for the outpost
```yaml
apiVersion: networking.k8s.io/v1beta1
kind: Ingress
metadata:
name: authentik-outpost
spec:
rules:
- host: *external host that you configured in authentik*
http:
paths:
- backend:
serviceName: authentik-outpost-example-outpost
servicePort: 9000
path: /akprox
```
This ingress handles authentication requests, and the sign-in flow.
Add these annotations to the ingress you want to protect
```yaml
metadata:
annotations:
nginx.ingress.kubernetes.io/auth-url: https://*external host that you configured in authentik*/akprox/auth?nginx
nginx.ingress.kubernetes.io/auth-signin: https://*external host that you configured in authentik*/akprox/start?rd=$escaped_request_uri
nginx.ingress.kubernetes.io/auth-response-headers: Set-Cookie,X-authentik-username,X-authentik-groups,X-authentik-email,X-authentik-name,X-authentik-uid
nginx.ingress.kubernetes.io/auth-snippet: |
proxy_set_header X-Forwarded-Host $http_host;
