## Installation
So far we are offering two different variants for the installation. You can choose between [Docker](https://www.docker.com/) or pre-built binaries which are stored on our download mirrors and GitHub releases. Maybe we will also provide system packages for the major distributions later if we see the need for it.
### Docker
TBD
### Binaries
TBD
## Configuration

### Configuration file
So far we support the file formats `JSON` and `YAML`, if you want to get a full example configuration just take a look at [our repository](https://github.com/owncloud/ocis-konnectd/tree/master/config), there you can always see the latest configuration format. These example configurations include all available options and the default values. The configuration file will be automatically loaded if it's placed at `/etc/ocis/konnectd.yml`, `${HOME}/.ocis/konnectd.yml` or `$(pwd)/config/konnectd.yml`.
## Usage
The program provides a few sub-commands on execution. The available configuration methods have already been mentioned above. Generally you can always see a formated help output if you execute the binary via `ocis-konnectd --help`.
### Server
The server command is used to start the http and debug server on two addresses within a single process. The http server is serving the general webservice while the debug server is used for health check, readiness check and to server the metrics mentioned below. For further help please execute:
{{< highlight txt >}}
ocis-konnectd server --help
{{< / highlight >}}
### Health
The health command is used to execute a health check, if the exit code equals zero the service should be up and running, if the exist code is greater than zero the service is not in a healthy state. Generally this command is used within our Docker containers, it could also be used within Kubernetes.
{{< highlight txt >}}
ocis-konnectd health --help
{{< / highlight >}}
## Metrics
This service provides some [Prometheus](https://prometheus.io/) metrics through the debug endpoint, you can optionally secure the metrics endpoint by some random token, which got to be configured through one of the flag `--debug-token` or the environment variable `KONNECTD_DEBUG_TOKEN` mentioned above. By default the metrics endpoint is bound to `http://0.0.0.0:9134/metrics`.
