Additional environment details (AWS, VirtualBox, physical, etc.):
docker installation with toolbox on mac

Steps to reproduce the issue:

  1. docker run -p 5000:5000 --log-driver=gelf --log-opt gelf-address=udp:// --log-opt tag=registry --log-opt env=test registry:2.4.1
    When running the registry with the command above any logs get to the graylog server just fine
    When deploying a second graylog server and changing the dns record to point to the new server:
  • From the host running the registry container and from the container I can resolve the IP for the new graylog server
  • all the registry logs are still being sent to the old graylog server

Describe the results you received:

  • gelf log driver seems to resolve the dns for the gelf address only at container startup

Describe the results you expected:

  • expecting the gelf driver to have some default or configurable ttl for the gelf address dns

@lauraglasu have you tried the test build mentioned in #17904 (comment) to see if that resolved your issue?
