docker logs -f stops when json-file rotates log file #37646
Description
Description
When Docker json-file log driver rotates the log file, applications streaming the log such as docker logs -f or logspout stop receiving new log events.
Steps to reproduce the issue:
- Start container that produces logs:
docker run --rm -d alpine sh -c 'while true; do echo $(date); done' - Start tailing logs:
docker logs -f <container-id> - Observe log file size at
/var/lib/docker/containers/<container-id>/<container-id>-json.log
Describe the results you received:
When the log file rotates, docker logs -f output stops.
Describe the results you expected:
I expect docker logs -f to continue outputting logs until terminated.
Additional information you deem important (e.g. issue happens only occasionally):
Seems to be a duplicate of #23913 which was supposed to have been fixed through #24514 in 1.13.
