Here's the error:

Here's my custom build:

FROM caddy:builder AS builder
 
RUN xcaddy build \
    --with github.com/lucaslorentz/caddy-docker-proxy/v2 \
    --with github.com/mholt/caddy-ratelimit \
    --with github.com/caddy-dns/cloudflare \
    --with github.com/WeidiDeng/caddy-cloudflare-ip \
    --with github.com/porech/caddy-maxmind-geolocation \
    --with github.com/caddyserver/transform-encoder \
    --with github.com/hslatman/caddy-crowdsec-bouncer/http@main \
    --with github.com/hslatman/caddy-crowdsec-bouncer/layer4@main \
    --with github.com/mholt/caddy-l4
 
FROM caddy:latest
 
COPY --from=builder /usr/bin/caddy /usr/bin/caddy

when I remove the caddy-docker-proxy, everything is good. Last time I use 2.8.4 is working fine. Buti when I upgrade to 2.9.1, i got this error. I use every image tag (builder, builder-alpine, 2.9.1-builder, etc) on docker hub and the result was the same.

I am having exactly the same error, I too am trying to install docker proxy + crowdsec bouncer modules. Can you tell how you fixed it ?

I am getting the same error.

Using:

RUN xcaddy build \
    --with github.com/yroc92/postgres-storage \
    --with github.com/caddy-dns/desec \
    --with github.com/lucaslorentz/caddy-docker-proxy/v2 \
    --with github.com/sablierapp/sablier/plugins/caddy=/sablier/plugins/caddy \
    --with github.com/fabriziosalmi/caddy-waf=/caddy-waf \
    --with github.com/hslatman/caddy-crowdsec-bouncer/http

You can see it in my PR #696

I'm puzzled. The above PR has been merged into main yet I still have that exact same error message when I try to create my custom image.

My Dockerfile is almost identical:

FROM caddy:builder AS builder

RUN xcaddy build \
    --with github.com/lucaslorentz/caddy-docker-proxy/v2 \
    --with github.com/hslatman/caddy-crowdsec-bouncer/http \
    --with github.com/sablierapp/sablier/plugins/caddy \
    --with github.com/caddy-dns/cloudflare

FROM caddy:latest

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

CMD ["caddy", "docker-proxy"]

So, what's wrong and how can I diagnose in more details?

[jpbaril]

Replying to myself.
It looks like the default behavior of the build process is not to use the latest code (commit) of the main branch but rather to use the code of the last officially released version, so 2.9.1, which released back in June 2024. Well, that's logical but I did not know that.
So to get the corrective code of last week's PR I had to specify the commit hash of that commit I wanted to include.

Could we then make a new release?
