Configure Docker with Configuration File
The preferred method for configuring the Docker Engine on Windows is using a configuration file. The configuration file can be found at 'c:\ProgramData\docker\config\daemon.json'.
Only the desired configuration changes need to be added to the configuration file. For example, this sample configures the Docker Engine to accept incoming connections on port 64500. All other configuration options will use default values.
{
"hosts": ["tcp://0.0.0.0:64500"]
}
