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 the journalctl 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 the tail 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 the log 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 the Get-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.
