Service 'kafka' failed to build: The command '/bin/sh -c /tmp/download-kafka.sh' returned a non-zero code: 8 with docker-machine about kafka-docker HOT 4 CLOSED

I had the same problem and it turned out to be caused by download-kafka.sh having Windows style EOL (CRLF instead of LF) when cloned. If you are running on a Windows machine, make sure that you configure git with core.autocrlf false.

git config --global core.autocrlf false

Looks like the problem with parsing a mirror list in download-kafka.sh.
For a temp solution you can comment out everything in download-kafka.sh
and add
wget -q http://mirrors.advancedhosters.com/apache//kafka/0.8.2.1/kafka_2.10-0.8.2.1.tgz -O "/tmp/kafka_${SCALA_VERSION}-${KAFKA_VERSION}.tgz

complete snippet:

#!/bin/sh

#mirror=$(curl --stderr /dev/null https://www.apache.org/dyn/closer.cgi\?as_json\=1 | sed -rn 's/.*"preferred":.*"(.*)"/\1/p')
#url="${mirror}kafka/${KAFKA_VERSION}/kafka_${SCALA_VERSION}-${KAFKA_VERSION}.tgz"
#wget -q "${url}" -O "/tmp/kafka_${SCALA_VERSION}-${KAFKA_VERSION}.tgz"
wget -q http://mirrors.advancedhosters.com/apache//kafka/0.8.2.1/kafka_2.10-0.8.2.1.tgz -O "/tmp/kafka_${SCALA_VERSION}-${KAFKA_VERSION}.tgz

There are two issues with this script running on OSX:

1. the OSX version of sed is not command-line compatible with gnu sed. The '-r' used by gnu needs to be '-E' for OSX.

2. The pattern pulling "preferred" from the mirror host is returning an extra '}' character at the end of the match on both gnu and OSX sed

Easiest solution is to install jq, and replace the sed command with jq --raw-output ".preferred"

this has been fixed in #49
