Subject [jira] [Commented] (KAFKA-5199) Run Kafka JUnit build inside Docker
Date Tue, 06 Mar 2018 05:07:01 GMT

    [ https://issues.apache.org/jira/browse/KAFKA-5199?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16387294#comment-16387294

Ewen Cheslack-Postava commented on KAFKA-5199:
----------------------------------------------

[~cmccabe] Do we still need this? I spent time quite awhile ago cleaning up the tests to not
rely on fixed ports as this, as well as things like fixed /tmp locations for data, are well
known causes of transient failures. This is also why ducktape avoids sharing resources as
aggressively (and expensively!) as it does.

Docker has definitely become more popular, but I don't think it is safe to assume every developer
will have it available. While we don't emphasize testing for them, Windows developers seem
the least likely to have it. Even developers on OS X may not, and anyone on a BSD that we'd
otherwise expect to work would probably be unable to run tests. Is baking a Linux-specific
tool into the build something we really want to do?

> We should run the Kafka JUnit build inside Docker.  This would avoid "port in use" conflicts
when running multiple jobs on the same node with a fixed port.  It would also help lock down
the specific Linux environment and make failures more reproducible.
