postStart exec breakOnError only fails when all containers have started

[jpraet]

I have a build with multiple docker images, and have configured startParallel = false, so the containers start sequentially.

The first container (db2express) is configured with a postExec wait action, with breakOnError=true.

I notice because of delay in the logs that the postExec script of the first container is executed before the second container is started. This is as expected. However, when the postExec script fails, I would expect the build to fail immediately. Instead, it first starts the remaining containers, and only once they are all started am I seeing the error from the postExec script.

This is docker-maven-plugin 0.24.0 and docker 0.12.6 on Windows 7.

I agree with you that the plugin should 'fail fast'. Shouldn't be hard to fix hopefully. I hope to jump on to this asap, but you could accelerate this by submitting a PR ;-)
