The resulting file will be called `codeship.env`, and the value will be appended if that file already exists.

You can also override few variable to have custom keys location and names.

```shell
docker run -it --rm -v $(pwd):/keys/ --env BASE_FOLDER="/keys" --env KEY_FILE="/keys/my_codeship_deploy_key" --env ENV_FILE="/keys/my_codeship.env" codeship/ssh-helper prepare
```
