I would like to self host ntfy.sh on railway. The config requires a cert and key: This is sever.yml ``` base-url: "https://ntfy.example.com" listen-http: ":80" listen-https: ":443" key-file: "/etc/letsencrypt/live/[Railway?].key" cert-file: "/etc/letsencrypt/live/[Railway?].crt" ``` This is my Dockerfile: ```FROM binwiederhier/ntfy COPY server.yml /etc/ntfy/server.yml ENTRYPOINT ["ntfy", "serve"] ``` Is this possible with railway?
