sven-lange-last opened a new pull request #3074: Don't fail if no Docker containers running URL: https://github.com/apache/incubator-openwhisk/pull/3074 The initial version failed if no Docker containers were running because an invalid regular expression was constructed for `find` command. With this change, the regular expression for filtering active virtual ethernet interfaces is only included active interfaces can be found. If Docker containers are running, there are always active interfaces. If no Docker containers are running, there may be no actives interfaces. Also see https://github.com/apache/incubator-openwhisk/pull/3007 for a discussion and test results.
