Cannot install plugin ratelimit

[lpellegr]

Here is the command used:

docker build --build-arg plugins=ratelimit -t local/caddy github.com/abiosoft/caddy-docker.git

and the ouput error:

can't load package: package caddy: ratelimit.go:2:10: invalid import path: "" error at 'building caddy'

The plugin name ratelimit is found when I test with caddyplug install ratelimit.

Any idea what the problem is? how can I build this great caddy image with the ratelimit plugin?

Did something upstream break the build system? I was getting this with plugins="git,login,jwt" and so I tried:

  caddy:
    image: abiosoft/caddy
    build:
      context: https://github.com/abiosoft/caddy-docker.git
      # args:
        # - plugins="git,login,jwt"
        # - enable_telemetry="false"
    restart: unless-stopped
    ...

i.e. default build variables. I got:

...
can't load package: package caddy: 
cors.go:2:10: invalid import path: ""
error at 'building caddy'
ERROR: Service 'caddy' failed to build: The command '/bin/sh -c VERSION=${version} PLUGINS=${plugins} ENABLE_TELEMETRY=${enable_telemetry} /bin/sh /usr/bin/builder.sh' returned a non-zero code: 1

@abiosoft Any idea what the problem is?

I'm experiencing this too, with cors, expires and git plugins. I've tried updating from 1.0.1 to 1.0.3 and no luck.

Has previously been working on a slight variation of the Dockerfile-no-stats, now with no changes it suddenly won't build.

[andrewandante]

For reference, my dockerfile is

#
# Builder copied and amended from https://github.com/abiosoft/caddy-docker/blob/master/Dockerfile-no-stats
#
FROM abiosoft/caddy:builder as builder

ARG version="1.0.3"
ARG plugins="realip,expires,cache,ipfilter"

# process wrapper
RUN go get -v github.com/abiosoft/parent

RUN VERSION=${version} PLUGINS=${plugins} ENABLE_TELEMETRY=false /bin/sh /usr/bin/builder.sh

#
# Final stage
#
FROM alpine:3.10
LABEL maintainer "Abiola Ibrahim <abiola89@gmail.com>"

ARG version="1.0.3"
LABEL caddy_version="$version"

# Let's Encrypt Agreement
ENV ACME_AGREE="false"

# Telemetry Stats
ENV ENABLE_TELEMETRY="false"

RUN apk add --no-cache \
    ca-certificates \
    git \
    mailcap \
    openssh-client \
    tzdata

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

# validate install
RUN /usr/bin/caddy -version
RUN /usr/bin/caddy -plugins

## Only expose 80
EXPOSE 80
WORKDIR /srv

# Set up our config and log file dirs
COPY ./conf/Caddyfile /etc/Caddyfile
RUN mkdir -p /etc/caddy/imports
COPY ./conf/imports/* /etc/caddy/imports/
COPY ./healthz.html /srv/healthz/index.html
COPY ./healthz.html /srv/index.html

COPY --from=builder /go/bin/parent /bin/parent

ENTRYPOINT ["/bin/parent", "caddy"]
CMD ["--conf", "/etc/Caddyfile", "--log", "stdout", "--agree=$ACME_AGREE"]

and my error output is similar:

go: extracting gopkg.in/yaml.v2 v2.2.2
can't load package: package caddy:
expires.go:2:10: invalid import path: ""
error at 'building caddy'

[abiosoft]

Let me try to reproduce this.

[lpellegr]

@abiosoft Did you succeed to reproduce the issue?

[flecno]

I have the same problem since last week. But I'm wondering that this breaks because there was no new changes in the builder image.

[andrewandante]

Small update from me - I had to rebuild it quickly, so ended up using the Dockerfile from https://hub.docker.com/r/productionwentdown/caddy/dockerfile as my base. However, what I did notice was this: https://github.com/productionwentdown/caddy/issues/4#issuecomment-508986178

Basically, you have to use the full name of the package, such as "github.com/captncraig/caddy-realip"

Mine is now up and running so I won't be re-trying this one, but it might be worth a quick test with the full plugin name, to see if that fixes it.

[abiosoft]

Some things have changed since the release of Caddy 2 beta. I'm working on updating caddy-docker to be compatible with Caddy 2. After that, these issues would be resolved.

[mcfilib]

i've started seeing the same with other plugins too but wasn't able to get it working with @andrewandante's workaround.

@abiosoft anything we can do to help?

[lpellegr]

FYI, the change proposed in https://github.com/abiosoft/caddy-docker/pull/223 as a workaround allows building an image with the desired plugins.

[mcfilib]

@lpellegr aha, thanks for pointing that out!

[elsbrock]

Can confirm this fixes the issue for me.
