Periods in environment variables


(Jerry) #1

The documentation here https://www.elastic.co/guide/en/elasticsearch/reference/6.2/docker.html says to use an environment var named "discovery.type". It caught my attention when RedHat's OpenShift does not support that format. Periods are not valid syntax (alpha numeric and underscores). When trying to investigate who's "issue" it is, I ran across some best practices which say not to use "." in env names: https://stackoverflow.com/questions/2821043/allowed-characters-in-linux-environment-variable-names

Thoughts?

Thanks.
