What is the default path to the Docker daemon configuration file on Linux? (Specify the full name of the file, Including path.)
正解：
/etc/docker/daemon.json
Explanation:
The default path to the Docker daemon configuration file on Linux is /etc/docker/daemon.json. This file is a JSON file that contains the settings and options for the Docker daemon, which is the service that runs on the host operating system and manages the containers, images, networks, and other Docker resources. The /etc
/docker/daemon.json file does not exist by default, but it can be created by the user to customize the Docker daemon behavior. The file can also be specified by using the --config-file flag when starting the Docker daemon. The file must be a valid JSON object and follow the syntax and structure of the dockerd reference docs12. References:
* Docker daemon configuration file - Medium3
* Docker daemon configuration overview | Docker Docs4
* docker daemon | Docker Docs5
