We're using the ansible-elasticsearch ansible role to configure our instances, and so far, it's working well. There's one problem we're running into, and that is that, due to government security requirements, /tmp needs to be on it's own partition and have the noexec flag set. Looking at the documentation, it seems like we can change the ES_TMPDIR environment variable to change the temp directory, but I don't see a way to do this with the role itself.
I can probably submit a merge request to allow that configuration, but I'm not able to full test the fix with anything other than CentOS 7. Can anyone help me get this resolved?
