# Server
Drone uses the `net/http` package in the Go standard library for high-performance `http` request processing. This section describes how to customize the default server configuration. This section is completely **optional**.
## Server Settings
This section lists all environment variables used to configure the server.
* `SERVER_ADDR` server address and port. Defaults to `:8000`
* `SERVER_KEY` ssl certificate key (key.pem)
* `SERVER_CERT` ssl certificate (cert.pem)
This example changes the default port to `:80`:
```bash
SERVER_ADDR=":80"
```
## Server SSL
Drone uses the `ListenAndServeTLS` function in the Go standard library to accept `https` connections. If you experience any issues configuring `https` please contact us on [gitter](https://gitter.im/drone/drone). Please do not log an issue saying `https` is broken in Drone (it isn't).
This example accepts `HTTPS` connections:
```bash
SERVER_ADDR=":443"
SERVER_KEY="/path/to/key.pem"
SERVER_CERT="/path/to/cert.pem"
```
> **NOTE** if the certificate is signed by a certificate authority, the cert should be the concatenation of the server's certificate followed by the CA's certificate.
When running Drone inside Docker, you'll need to mount a volume containing the certificate:
```bash
docker run
--volume /path/to/cert.pem:/path/to/cert.pem \
--volume /path/to/key.pem:/path/to/key.pem \
```
