[imceballos]

i need to make this configuration, this is typical on Settings/Docker Engine, but my problem its that i using Docker Toolbox ( with Virtual Box), what is the command or the way to configurate this (On toolbox):

{
“bip”: “XXXXXXXXXX”,
“debug”: true,
“experimental”: true,
“fixed-cidr”: “XXXXXXXX”
}
