Is it safe to make outpost (forwardAuth proxy) available from the internet?

[RogerSik]

I have authentik running on kubernetes.

There are some baremetal server with docker-compose which has docker containers. The authentication is done with forwardAuth and local authentik proxy.

My question ist can i make outpost.authentik.example.org on my kubernetes and point the bare-metal server container to this address? So i don't need to setup on every server an extra proxy instance?

Has this security implication? In the docs i couldn't find regarding this.
