Labels with dots get parsed as a hash and it builds structures out of it, from my searching it looks like there were commits in code to replace dots with dashes in kubernetes and docker labels. But the dots are not replaces and instead data structures are built which breaks following labels too. I've tried it with and without autodiscover mode, also I'm using latest version of filebeat 6.3.2. If there are commits that didn't make it to that release, I'm willing to build the binaries + containers myself.
