Build error on docker with alpine image

[MarcAntoine-Arnaud]

Hello,

I'm trying to build my Elixir project on an alpine image (which depends on rabbit_common project). When I call make I got:

 ERLC  
src/ssl_compat.erl:47: Warning: ssl:connection_info/1: removed in 20.0; use ssl:connection_information/[1,2] instead
src/ssl_compat.erl:67: Warning: ssl:connection_info/1: removed in 20.0; use ssl:connection_information/[1,2] instead
awk: bad regex '{modules,': Repetition not preceded by valid expression
make[1]: *** [Makefile:80: ebin/rabbit_common.app] Error 1
make: *** [erlang.mk:4913: app] Error 2

To repeat issue:

docker pull elixir:1.5.2-alpine
docker run -it elixir:1.5.2-alpine /bin/sh

then inside the container:

apk update
apk add git make curl
mix local.hex --force
mix local.rebar --force
mix hex.info
mix archive.install https://github.com/phoenixframework/archives/raw/master/phx_new.ez
mix phx.new testbuild
cd testbuild

Add AMQP dependency into mix.exs: {:amqp, "~> 0.3.0"},

mix compile

Remarks:

• Forcing to use release 3.6.12 do the same error.
• Building rabbit_common directly on an alpine works.

The Rabbit_common team mention the error appends here: https://github.com/rabbitmq/rabbitmq-common/blob/master/erlang.mk#L5136

Is it possible to have some help on that ?

Thanks, Marc-Antoine

You say that building directly on alpine works, but not on alpine inside a Docker container? What's the difference?

[MarcAntoine-Arnaud]

Sorry no, everything is inside an Alpine docker container. It's just if I try to build the project itself (git clone, and run make), it works. The error appends when I create an Elixir project which have amqp (and rabbit_common) as dependencies. Is it clear ?

[essen]

Can you add $(info $(shell env)) to the rabbit_common Makefile and paste the result? Would also be good to have the command that runs this Makefile.

Thanks for your help

What's the output of env on the terminal where you build manually?

[MarcAntoine-Arnaud]

env is

HOSTNAME=532b957a8499
SHLVL=1
OLDPWD=/
HOME=/root
OTP_VERSION=20.1.6
TERM=xterm
PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
LANG=C.UTF-8
ELIXIR_VERSION=v1.5.2
PWD=/testbuild

I got no clue I'm afraid. Can we do a last test to figure out if it's a Docker issue, an Elixir/Mix issue or a combination of both? Would involve repeating the same steps outside of Docker to see if it still happens. If it does, it's Elixir/Mix. If it doesn't, then it's either Docker or Docker+Elixir/Mix. I can probably take over after that when time allows (don't know when unfortunately).

Also if building on Docker is the only issue a workaround would be to build separately and then add the files to Docker, if that's possible. I'm not familiar with Docker and Elixir/Mix.

I am also facing this issue. What solved it for me is that installing gawk (GNU Awk) package in Alpine. I think the issue is some incompatibility between Busybox Awk and GNU Awk.

[essen]

Cheers. I guess this warrants a note in the installation part of the guide. Thanks!

[MarcAntoine-Arnaud]

@iamd3vil thanks for the solution. I test it, and it works for me too. Thanks too !

[queer]

@iamd3vil Worked perfectly, thanks!

[essen]

Added the note, closing, thanks!
