How to increase docker-machine memory Mac

You can do this via the command line. For example, to change the machine from the default 1cpu/2048MB RAM run:

docker-machine stop
VBoxManage modifyvm default --cpus 2
VBoxManage modifyvm default --memory 4096
docker-machine start

You can then check your settings:

VBoxManage showvminfo default | grep Memory
VBoxManage showvminfo default | grep CPU

And for docker-machine inspect to report the correct state of things, edit ~/.docker/machine/machines/default/config.json to reflect your changes.

when you create docker machine, you can nominate the memory size:

docker-machine create -d virtualbox --virtualbox-memory 4096 default

Let me know if this helps.
