AMQP_HOST_PORT format issue

[wildsurfer]

Hi. I'm experiencing an issue with setting AMQP_HOST_PORT to FQDN instead of IP.

$ docker logs rabbitmqexample_postgresql-to-amqp_1
    Finished release [optimized] target(s) in 0.6 secs
     Running `target/release/postgresql-to-amqp`
thread 'main' panicked at 'amqp_host_port should be in format '127.0.0.1:5672': AddrParseError(())', /checkout/src/libcore/result.rs:859
note: Run with `RUST_BACKTRACE=1` for a backtrace.

Here is sample docker-compose.yml file to reproduce the issue. Save it and run docker-compose up and you will see the same error message as above.

version: '2'
services:
  postgresql:
    image: postgres:9.5.3
    ports:
      - "5432"
    depends_on:

    environment:

      - AMQP_QUEUE_NAME="myqueue"
    depends_on:

My workaround for now is to build my own Docker image

Dockerfile:

FROM fgribreau/postgresql-to-amqp:0.1.3
RUN apt-get update && apt-get install -y dnsutils
COPY ./run.sh /root
CMD /root/run.sh

run.sh:

#!/bin/bash

IFS=’:’ read -ra ARR <<< "$AMQP_HOST_PORT"

FQDN_HOST=${ARR[0]}
FQDN_PORT=${ARR[1]}
IP=$(dig +short $FQDN_HOST | awk '{print $1}')

AMQP_HOST_PORT="$IP:$FQDN_PORT"

echo $AMQP_HOST_PORT

echo "Sleeping for 10 seconds. To ensure that rabbitmq already started";
sleep 10

cargo run --release
