Locating System Logs

Docker Desktop

In the Docker Desktop user interface, view Volumes using the menu on the left side of the screen, as shown in the following image.

Click the tdq_tdq-logs volume.

A list of containers in the tdq_tdq-logs is displayed, as shown in the following image.

Navigate to the DATA tab and select a log file. A menu will appear that will allow you to download the file, as shown in the following image.

If you are using the WSL2 engine with Docker Desktop, then the tdq-logs volume can be accessed through the WSL2 file system at:

/mnt/wsl/docker-desktop-data/version-pack-data/community/docker/volumes/tdq_tdq-logs/_data

You could tail the profiler log, for example, as follows:

sudo tail -f /mnt/wsl/docker-desktop-data/version-pack-data/community/docker/volumes/tdq_tdq-logs/_data/tdq-profiler.log

Linux

On Linux, Docker volumes are usually found in /var/lib/docker/volumes, so you could tail the profiler log as follows:

sudo tail -f /var/lib/docker/volumes/tdq_tdq-logs/_data/tdq-profiler.log

Copying Logs From a Container

If the above methods do not work, you can use the Docker cp command to retrieve the log files from a running container. First, get the container ID for tdq-butler:

`$ docker ps`
`CONTAINER ID`	`IMAGE NAME`	`COMMAND`	`CREATED`	`STATUS`	`PORTS`
`ca67baeeefb6`	`tdq-tdq-nginx`	`"/docker-entrypoint.…"`	`25 hours ago`	`Up About a minute`	`0.0.0.0:9800->80/tcp`
`45141770213a`	`tdq-tdq-valet-ui`	`"npm start"`	`25 hours ago`	`Up About a minute`	`0.0.0.0:9801->81/tcp`
`79e739ebed6c`	`tdq-tdq-valet-services`	`"/tdq-valet-services…"`	`25 hours ago`	`Up About a minute`	`0.0.0.0:9803->83/tcp`
`b385822c72be`	`tdq-tdq-butler`	`"/tdq-butler/docker-…"`	`25 hours ago`	`Up About a minute`	`0.0.0.0:9807->87/tcp`

Then copy the /logs directory from the container to the host, using the ID of the tdq-butler container:

$ docker cp b385822c72be:/tdq-butler/logs .

$ ls -l ./logs/
total 48
