Error building Docker image with the Caddy module

[FPDK]

Hi,

When I execute this Dockerfile (Docker v. 4.23.0):

ARG CADDY_VERSION=2.8.4

FROM caddy:${CADDY_VERSION}-builder AS builder

RUN xcaddy build --with github.com/protomaps/go-pmtiles/caddy

FROM caddy:${CADDY_VERSION}-alpine

COPY --from=builder /usr/bin/caddy /usr/bin/caddy

# Copy Caddyfile and .pmtiles into the container
COPY Caddyfile .
COPY monaco-latest.pmtiles .

# Expose the port that Caddy will run on
EXPOSE 80
EXPOSE 8080
EXPOSE 443

# Start Caddy
CMD ["caddy", "run", "--config", "Caddyfile"]

I get this error during the build step:

=> ERROR [builder 2/2] RUN xcaddy build --with github.com/protomaps/go-pmtiles/caddy                                                                                                                110.9s

I have attached the full log:
docker-caddy-log.log

When I don't include the go-pmtiles module (i.e. remove the --with argument) the build-step executes without errors.
I have tried building with another custom module (github.com/dunglas/mercure/caddy) and this works fine as well.

Am I doing something wrong?

Thanks for the detailed report. Should be fixed on main and in v1.22.1, can you try that?

[FPDK]

It works fine now. Thank you for the quick response.
