However, I'm having trouble with even the most basic setting, and I don't know what might be wrong, so any help will be much appreciated. I have developed a very simple docker image and corresponding Galaxy tool, so that I get it working before starting with the actual tool, but when I execute it through Galaxy it simply stays executing forever, instead of failing or terminating.

My image simply executes a shell script that reads the content of a file and concatenates a string to it. The image:

FROM busybox:ubuntu-14.04
MAINTAINER Mikel Egaña Aranguren <mikel.egana.aranguren@gmail.com>

RUN mkdir /sadi
COPY test-io.sh /sadi/
RUN chmod a+x /sadi/test-io.sh
ENV PATH $PATH:/sadi

The test-io.sh script within the image:

#!/bin/sh

cat $1
echo "AAA"

Invoking the container and executing the script through a normal shell works fine:

REPOSITORY                                   TAG                 IMAGE ID            CREATED             VIRTUAL SIZE
mikeleganaaranguren/busybox-galaxy-test-io   v1                  9c2b8bdade1d        54 minutes ago      5.609 MB

docker run -i -t mikeleganaaranguren/busybox-galaxy-test-io:v1

BusyBox v1.21.1 (Ubuntu 1:1.21.0-1ubuntu1) built-in shell (ash)
Enter 'help' for a list of built-in commands.

~ #
~ # echo "BBB" > test
~ # test-io.sh test
BBB
AAA

This is the tool file I'm using in Galaxy:

<tool id="SADIBUSYBOX" name="SADIBUSYBOX">
    <description>IO</description>
    <requirements>
      <container type="docker">mikeleganaaranguren/busybox-galaxy-test-io:v1</container>
    </requirements>
    <command>
      test-io.sh $input > $output
    </command>
    <inputs>
        <param name="input" type="data" label="Dataset"/>
    </inputs>
    <outputs>
        <data format="txt" name="output" />
    </outputs>
    <help>
    </help>
</tool>

And my job_conf.xml:

<?xml version="1.0"?>
<!-- A sample job config that explicitly configures job running the way it is configured by default (if there is no explicit config). -->
<job_conf>
    <plugins>
        <plugin id="local" type="runner" load="galaxy.jobs.runners.local:LocalJobRunner" workers="4"/>
    </plugins>
    <handlers>
        <handler id="main"/>
    </handlers>
    <destinations default="docker_local">
        <destination id="local" runner="local"/>
    <destination id="docker_local" runner="local">
      <param id="docker_enabled">true</param>
        </destination>
    </destinations>
</job_conf>

As I said, when I execute the tool in Galaxy, it simply executes forever, it stays in a "yellow state", till I kill the Galaxy server. The log says:
