Official docker image

[gaetancollaud]

Hello,

Would it be possible to have an official docker image published on dockerhub ?

I will use what I found in #5 for now but it could be great to have an official image instead.

Best regards

Hi! Absolutely, it sounds like a good idea. I'll try to look into it today if I get the time or next monday. I'll let you know where I get with it.

Great !

This is what I got so far (I will update when it works, right now it crash at boot, not sure why..., but I think it's just my mosquitto.conf)

FROM golang as builder

WORKDIR /app

# download
RUN wget https://github.com/iegomez/mosquitto-go-auth/archive/0.2.0.tar.gz \
	&& ls -l \
	&& tar xvf *.tar.gz --strip-components=1 \
	&& rm -Rf *.tar.gz

# add mosquitto dev dependencies
RUN apt-get update && apt-get install -y libmosquitto-dev mosquitto-dev

# build
RUN make

# Extend official eclipse-mosquitto
FROM eclipse-mosquitto
COPY --from=builder /app/go-auth.so /mosquitto

What's the error you get when it crashes?

[gaetancollaud]

That's the issue... I have no error. It just crash

1553875447: mosquitto version 1.5.8 starting
1553875447: Config loaded from /mosquitto/config/mosquitto.conf.
Segmentation fault

My mosquitto.conf:

port 1883

# Auth
auth_plugin /mosquitto/go-auth.so
auth_opt_backends http

auth_opt_http_port 8080
auth_opt_http_host myServer
auth_opt_http_getuser_uri /api/mqtt-getuser
auth_opt_http_superuser_uri /api/mqtt-superuser
auth_opt_http_aclcheck_uri /api/mqtt-aclcheck

# Websocket
listener 9001
protocol websockets

I've just tried with the last source (instead of the release 2.0.0), but same Segmentation fault error :(

Looks related to #14

It probably is, I still haven't tried Alpine.

If it helps, I just modified a bit an image I had to hack to serve loraserver, lora-app-server, mosquitto and the plugin some time ago. I know almost nothing about docker so it's probably awful, but it works and maybe you can tidy it up to make something useful. The Dockerfile looks like this:

FROM ubuntu:latest
RUN apt-get update && apt-get install -y supervisor libwebsockets8 libwebsockets-dev libc-ares2 libc-ares-dev openssl uuid uuid-dev wget build-essential git
RUN mkdir -p /var/log/supervisor
COPY supervisord.conf /etc/supervisor/conf.d/supervisord.conf

RUN mkdir loraserver lora-app-server mosquitto
RUN mkdir mosquitto/auth mosquitto/conf.d
#RUN mkdir .config .config/loraserver .config/lora-app-server

#RUN mkdir /etc/loraserver
#RUN mkdir /etc/lora-app-server

#COPY loraserver /loraserver/loraserver
#COPY lora-app-server lora-app-server/lora-app-server
#COPY configuration/loraserver.toml /etc/loraserver/loraserver.toml
#COPY configuration/lora-app-server.toml /etc/lora-app-server/lora-app-server.toml

RUN wget http:https://mosquitto.org/files/source/mosquitto-1.5.7.tar.gz
RUN tar xzvf mosquitto-1.5.7.tar.gz

RUN mkdir -p /var/lib/mosquitto
RUN mkdir -p /var/log/mosquitto 

RUN cd mosquitto-1.5.7 && make WITH_WEBSOCKETS=yes && make install && cd ..
RUN groupadd mosquitto
RUN useradd -s /sbin/nologin mosquitto -g mosquitto -d /var/lib/mosquitto
RUN chown -R mosquitto:mosquitto /var/log/mosquitto/
RUN chown -R mosquitto:mosquitto /var/lib/mosquitto/


RUN wget https://dl.google.com/go/go1.12.1.linux-amd64.tar.gz && tar -C /usr/local -xzf go1.12.1.linux-amd64.tar.gz

RUN export PATH=$PATH:/usr/local/go/bin && mkdir -p go/src/github.com/iegomez && cd go/src/github.com/iegomez && git clone https://github.com/iegomez/mosquitto-go-auth.git && cd mosquitto-go-auth/ && export CGO_CFLAGS="-I/usr/local/include -fPIC" && export CGO_LDFLAGS="-shared" && make

COPY mosquitto.conf mosquitto/mosquitto.conf
COPY go-auth.conf mosquitto/conf.d/go-auth.conf
COPY auth/acls mosquitto/auth/acls
COPY auth/passwords mosquitto/auth/passwords

EXPOSE 1883 1884 8080

CMD ["/usr/bin/supervisord"]

I just pushed a repo that includes the conf files: https://github.com/iegomez/mga-docker-test.

As I said, I haven't worked with docker except for that hacky image I made in a hurry, so if you are willing I'd really appreciate any contributions on this. If you aren't able, I'll take a good look at docker documentation and try to assemble a proper image as soon as I get the time.

This is a working version, but not optimized at all since it uses ubuntu:latest

FROM golang as builder

WORKDIR /app

# add mosquitto dev dependencies
RUN apt-get update && apt-get install -y libmosquitto-dev mosquitto-dev

# download
RUN wget https://github.com/iegomez/mosquitto-go-auth/archive/0.2.0.tar.gz \
	&& ls -l \
	&& tar xvf *.tar.gz --strip-components=1 \
	&& rm -Rf *.tar.gz


# build
RUN make



FROM ubuntu:latest

RUN apt-get update && \
	apt-get install -y mosquitto

COPY --from=builder /app/go-auth.so /home

ENTRYPOINT ["sh", "-c", "/usr/sbin/mosquitto -c /etc/mosquitto/mosquitto.conf" ]

Hi, I just came upon this: https://github.com/sgerrand/alpine-pkg-glibc. Haven't tried it myself though.

I also saw this issue, where the last comment mentions some workaround for libc: docker-library/golang#209.

[iegomez]

Hi, @gaetancollaud. Sorry I haven't done anything yet, I couldn't get the time. Were you able to try any of those?

I'll close this for inactivity, I'll let you know if I release an official docker image.
