How to locate the Docker daemon log?
The location of the Docker daemon log file can vary depending on your operating system and the configuration of your Docker installation. Here are the common locations:
Linux (systemd):
/var/log/syslog
or/var/log/messages
. You can use thejournalctl
command to view the logs. For example, to view the last 100 lines of the Docker daemon log, you can run:journalctl -u docker.service -n 100
Linux (non-systemd):
/var/log/docker.log
or/var/log/messages
. You can use thetail
command to view the logs. For example, to view the last 100 lines of the Docker daemon log, you can run:tail -n 100 /var/log/docker.log
macOS:
/var/log/system.log
. You can use thelog show
command to view the logs. For example, to view the last 100 lines of the Docker daemon log, you can run:log show --predicate 'subsystem == "com.docker.docker"' --info --last 100
Windows:
C:\ProgramData\Docker\log
. You can use theGet-Content
command to view the logs. For example, to view the last 100 lines of the Docker daemon log, you can run:Get-Content -Tail 100 "C:\ProgramData\Docker\log\dockerd.log"
Note that the above locations may vary based on your Docker installation and configuration. If you're unable to locate the Docker daemon log, you can check the Docker documentation or seek help from the Docker community.
