How to add custom modules to Caddy Image?

[rajasekhar-gundala]

Which image/versions are related to this issue/feature request?

Hello,
Thank you very much for the project.

I am searching for documentation to add custom modules to Chainguard Caddy Image. We need DNS modules (like Cloudflare) in order to work with TLS.

I know how to extend the base Caddy Image with custom modules. There is a section called Adding custom Caddy modules that explains well to achieve it.

Can you please guide me how to add custom modules to Chainguard Caddy Image?

Issue/Feature description

I was able to build the custom image using below Dockerfile.
After that I used the image in my docker compose file. But not able to access the sites.

Am I doing anything wrong?

FROM cgr.dev/chainguard/caddy:latest-dev AS builder

USER root

RUN apk add bash ca-certificates git libcap mailcap xcaddy go

RUN xcaddy build \
    --with github.com/caddy-dns/cloudflare \
    --with github.com/abiosoft/caddy-hmac \
    --with github.com/lolPants/caddy-requestid
    
FROM cgr.dev/chainguard/caddy:latest-dev

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