The dockerd --debug
command is used to start the Docker daemon with debug output enabled. The Docker daemon (dockerd
) is the background service responsible for managing Docker containers on a host machine.
By running dockerd --debug
, you enable additional logging and debugging information for the Docker daemon. This can be helpful for troubleshooting and diagnosing any issues with Docker containers or the Docker daemon itself.
When --debug
is passed as a flag to the dockerd
command, it enables various levels of debugging information, including detailed logging of internal operations, network interactions, and other relevant events. This additional output can be useful for diagnosing and resolving problems, but it can also generate a large amount of log data, so it's typically used only when necessary.
Note that the exact level and format of debug output may vary depending on the Docker version and configuration settings.
