missing docker unix group

[drema201]

Hi,

I had an issue with missing "docker" unix group.
I am on Window 7 with VirtualBox VM 6.0.0.
Error message is just after "Configuring Docker proxy"
Faulty command is : chown ... root:docker

I've made a quick fix by adding that group as
config.vm.provision "shell", inline: <<-SHELL
echo 'Add missing docker unix group'
groupadd docker
/vagrant/all.sh #{OPENSHIFT_RELEASE}
SHELL

after that initial installation goes w/o any issues.

Did you specify a different vagrant box image instead of centos/7 ? the name of the docker group should be dockerroot when using installing docker in centos.
