# Authelia on Kubernetes

Authelia is now available on Kube in order to protect your most critical

applications using 2-factor authentication.

This example leverages [ingress-nginx](https://github.com/kubernetes/ingress-nginx)

instructions written in the page.

|

## How does it work?
|
||||
|
||||
### Authentication via Authelia
|
||||
|
||||
In a Kube clusters, the routing logic of requests is handled by ingress
|
||||
controllers which follow the provided ingress configurations.
|
||||
controllers following rules provided by ingress configurations.
|
||||
|
||||
In this setup, requests goes through a [ingress-nginx](https://github.com/kubernetes/ingress-nginx)
|
||||
controller which forward verification requests to Authelia in order to allow
|
||||
or deny access.
|
||||
In this example, [ingress-nginx](https://github.com/kubernetes/ingress-nginx)
|
||||
controller has been installed to handle the incoming requests. Some of them
|
||||
(specified in the ingress configuration) are forwarded to Authelia so that
|
||||
it can verify whether they are allowed and should reach the protected endpoint.
|
||||
|
||||
The authentication is provided at the ingress level by an annotation called
|
||||
`nginx.ingress.kubernetes.io/auth-url` that is filled with the URL of
|
||||
Authelia's verification endpoint.
|
||||
The ingress controller also requires the ingress provides the URL of the
|
||||
authentication portal in case the user is not yet authenticated.
|
||||
The ingress controller also requires the URL to the
|
||||
authentication portal so that the user can be redirected in case she is not
|
||||
yet authenticated.
|
||||
|
||||
Those annotations can be seen in `apps/secure-ingress.yml` configuration.
|
||||
|
||||
### Production grade infrastructure
|
||||
|
||||
What is great about using [ingress-nginx](https://github.com/kubernetes/ingress-nginx)
|
||||
What is great with using [ingress-nginx](https://github.com/kubernetes/ingress-nginx)
|
||||
is that it is compatible with [kube-lego](https://github.com/jetstack/kube-lego)
|
||||
that makes renewal of SSL certifiactes automatic.
|
||||
which removes the usual pain of manual SSL certificate renewals. It uses
|
||||
letsencrypt to issue and renew certificates every three month without any
|
||||
manual intervention.
|
||||
|
||||
## What do I need know to deploy it in my cluster?
|
||||
|
||||
Given your cluster is already made of an LDAP server, a Redis cluster, a Mongo
|
||||
cluster and a SMTP server, you'll only need to install the ingress-controller
|
||||
and Authelia whose configurations are respectively in `ingress-controller` and
|
||||
`authelia` directories.
|
||||
and Authelia whose kubernetes deployment configurations are respectively in
|
||||
`ingress-controller` and `authelia` directories. A template configuration
|
||||
is provided there, you just need to create the configmap to use it within
|
||||
the cluster.
|
||||
|
||||
### I'm already using ingress-nginx
|
||||
|
||||
If you're already using ingress-nginx as your ingress controller, the only
|
||||
thing you'll need to change is the nginx template used by the controller to
|
||||
make it compatible with Authelia. The template is located in
|
||||
`ingress-controller/configs/nginx.tmpl`. Make it a configmap and pass it to
|
||||
your controller arguments.
|
||||
If you're already using ingress-nginx as your ingress controller, you only
|
||||
need to install Authelia with its configuration and that's it!
