title: Overview

An outpost is a single deployment of a authentik component, which can be deployed in a completely separate environment. Currently, Proxy Provider and LDAP are supported as outposts.
![](outposts.png)
Upon creation, a service account and a token is generated. The service account only has permissions to read the outpost and provider configuration. This token is used by the Outpost to connect to authentik.
authentik can manage the deployment, updating and general lifecycle of an Outpost. To communicate with the underlying platforms on which the outpost is deployed, authentik has several built-in integrations.
- If you've deployed authentik on docker-compose, authentik automatically creates an integration for the local docker socket (See [Docker](./integrations/docker.md)).
- If you've deployed authentik on Kubernetes, with `kubernetesIntegration` set to true (default), authentik automatically creates an integrations for the local Kubernetes Cluster (See [Kubernetes](./integrations/kubernetes.md)).
To deploy an outpost with these integrations, simply select them during the creation of an Outpost. A background task is started, which creates the container/deployment. You can see that Status on the System Tasks page.
To deploy an outpost manually, see:
- [Kubernetes](./manual-deploy-kubernetes.md)
- [docker-compose](./manual-deploy-docker-compose.md)
## Configuration
Outposts fetch their configuration from authentik. Below are all the options you can set, and how they influence the outpost.

## Metrics
Each authentik outpost has a Prometheus metrics endpoint accessible under port `:9300/metrics`. This endpoint is not mapped via docker, as the endpoint doesn't have any authentication.
For the embedded outpost, the metrics of the outpost and the metrics of the core authentik server are both returned under the same endpoint.

### Configuration
Since the outpost uses OAuth2, there is some configuration required.
Since authentik doesn't know it's own "primary" URL, there might be some configuration required.
On a fresh authentik install, your Outpost list will look like this:
By default, when opening the admin dashboard on a fresh install, authentik will automatically configure the outpost to use the same URL as was used to access authentik.

Click the edit button on the right of the column, and set the value of `authentik_host` to the URL you want to login with.
If this isn't correct, or needs to be changed, click the edit button on the right of the outpost, and set the value of `authentik_host` to the URL you want to login with.
Make sure to set it to full URL, only configuring a hostname or FQDN will not work.
Additionally, most of the other configuration options can be used as with any other outpost, except from items which are marked as "non-embedded"
import Configuration from "../_config.md";
