---------------------------------------

             Summary: groovy-based configuration tries to resolve the hostname eagerly, failing in environments with no hostname
                 Key: LOGBACK-1370
                 URL: https://jira.qos.ch/browse/LOGBACK-1370
             Project: logback
          Issue Type: Bug
          Components: logback-classic
    Affects Versions: 1.2.3
         Environment: Aws Lambda
            Reporter: Kirill Morozov
            Assignee: Logback dev list


When configuring logback via a logback.groovy, the first thing that the GafferConfigurator does is call {{binding.setProperty("hostname", ContextUtil.localHostName);}}.

In a serverless environment, such as AWS Lambda, this fails with a UnknownHostException. As I understand it Lambdas don't have hostnames as they can't be addressed from the internet.

We should either wrap this line in a try/catch or move the hostname resolution to where it is used.
