Windows docker -f doesn't follow instantly #30046
Description
BUG REPORT INFORMATION
Description
Windows docker -f doesn't follow instantly as expected. Most the times It just outputted the history logs and stuck there , seldom it outputted new logs every one minute.
This happens ONLY to Windows docker.
Steps to reproduce the issue:
1.
docker run -d --name=log-tester microsoft/windowsservercore powershell while ($true) {$d=Get-Date; write-host 'Time is:' $d; Sleep 1}
2.
docker logs -f log-tester
Describe the results you received:
Logs didn't get printed every second. Instead, only history logs were outputted but new logs either didn't printed (most testcases) or printed in a batch every one minute (in very few testcases)
Describe the results you expected:
logs should be outputted in stream instantly. In this particular testcase, logs should get printed every second.
