Error attempting to save store: write ...: no space left on device

Hi,

I am running a docker container on Azure using docker-machine. I have created a new Virtual Machine (A “Standard_F16s_v2” machine with image “canonical:UbuntuServer:16.04.0-LTS:latest”), using docker-machine create and the installation went as expected. However, I did get the following error message:

Error attempting to save store: write /home/username/.docker/machine/machines/machinename/config.json.tmp610214298: no space left on device

It is unclear to me what this error means. Is it related to storage on the VM itself or to some general storage on my Azure account? So far, it does not seem to cause any problems when spinning up a container, but I am wondering how this error might give problems in the future and how I can resolve it.

Any clarification would be very helpful. Thanks!
