pipe and redirect hangs

[madsbredholt]

We are unable to pipe and redirect,(stdout, stderr hangs) data out of docker, due to chances done in the sematext logagent.

This became an issue for us after upgrading the logagent from version 2.0.184 to 3.0.18, 3.0.21

The following can be done to recreate the problem locally.

The following is an example that hangs on ouput.

docker run -i --rm -e LOGSENE_ENABLED=false --log-driver none mysql:5.7.27 sh -c ”mysqldump ...” > dump.sql 2> dump_err.log

Our environment details:

AWS CentOs 7 AMI

Docker Engine 19.03.1 and 19.03.5

Hi, when you use no log diver, or any other log driver than json-file or journald, you probably don't need to set LOGSENE_ENABLED=false.

Please try:

docker run -i --rm --log-driver none mysql:5.7.27 sh -c ”mysqldump ...” > dump.sql 2> dump_err.log

I assume Logagent will not collect the output, and will not make a detach API call for the container.

Hi We will git it a try and get back to you. Regards Mads
