How to make docker fail or check version exists

Question

I have maven running a bash to build something with Docker.

<plugin>
    ...
    <artifactId>maven-antrun-plugin</artifactId>
        ...
            <exec executable="${basedir}/generate.sh" failonerror="true">
                                <arg value="${thrift.version}" />
...

The bash script runs something like:

for file in src/main/thrift/*.thrift; do
    echo "Compiling ${file}"
    docker run {...} thrift:${THRIFT_VERSION} thrift {...}
done

My problem is, when Docker can't find the version I'm requesting, it shows an error in console but it doesn't "fail": it just keeps building.

 [exec] Compiling src/main/thrift/amsException.thrift
 [exec] docker: Tag 0.9.0 not found in repository docker.io/library/thrift.
 [exec] See 'docker run --help'.
 [exec] Unable to find image 'thrift:0.9.0' locally

and consequently maven says

[INFO] ------------------------------------------------------------------------
[INFO] BUILD SUCCESS
[INFO] ------------------------------------------------------------------------

How can I make Docker throw and error when it can't find the version? My final goal is Maven failing to clean-install when this happens.

Cheers!

You can check docker run exit code. If it's not 0, then abort your script.

for file in src/main/thrift/*.thrift; do
    echo "Compiling ${file}"
    docker run {...} thrift:${THRIFT_VERSION} thrift {...}
    if [ $? != 0 ]; then
        exit -1
    fi
done
