```
```bash
$ ssh-keygen -t rsa -b 4096 -N '' -f ./ssh-chat-key
```
Run the docker image:
```
```bash
$ docker run -p 2022:2022 -v /ssh-chat-key:/ssh_key -v /admin_keys:/admin_keys byreqz/ssh-chat:latest
```
You may supply additional arguments to the image, example:
```
```bash
$ docker run -p 22:22 -v /ssh-chat-key:/ssh_key -v /admin_keys:/admin_keys byreqz/ssh-chat:latest --bind ":22"
```
