I’m trying to host a Gemini server using the Agate project. Since Gemini is a different protocol from http, my fly.toml file looks like this:
…
[build]
dockerfile = "Dockerfile.agate"
[[services]]
internal_port = 1965
protocol = "tcp"
processes = ["app"]
[[services.ports]]
port = 1965
My dockerfile looks like this:
FROM alpine:latest
EXPOSE 1965 # Note that Gemini apps are served from port 1965.
RUN apk add cargo && wget -O source.tar.gz $(wget -qO- https://api.github.com/repos/mbrubeck/agate/releases/latest | sed -nE 's/^.*"tarball_url"\s*:\s*"([^"]+)".*$/\1/p')&& tar xzf source.tar.gz && mv /mbrubeck-agate-* /agate && cd agate && cargo build --release
RUN cp /agate/target/release/agate /usr/bin/agate
COPY ./start.sh ./start.sh
ENTRYPOINT ["/bin/sh", "start.sh"]
and the start.sh entrypoint consists merely of this:
#!/bin/sh
exec agate --content /var/gemini/ --addr 0.0.0.0:1965 --hostname myprojectname.fly.dev --lang en-US --certs /var/certs
My dockerfile works locally; I can build the image and run it from Docker Desktop and the server works just fine.
From the fly.io logs, it looks like my server starts successfully:
[agate] Started listener on 0.0.0.0:1965
However, it doesn’t seem to receive requests made from my browser; no requests are logged, so it seems as though requests aren’t making it through.
Would appreciate any help!
