xvrl opened a new pull request #9019: allow druid.host to be undefined in the docker image
URL: https://github.com/apache/incubator-druid/pull/9019
 
 
   It is currently not possible to unset the `druid.host` property in the docker image to let Druid default to the canonical hostname. It always gets set to the container's IP address. Passing the override environment varialbe `druid_host=` unfortunately does not solve the problem, as this gets interpreted as empty string and does not let the default kick in.
   
   This change adds the option to pass DRUID_SET_HOST=0 as environment variable to disable the default behavior, and allows passing a common runtime.properties file without druid.host.
