Vagrant provisioning scripts

An example "create-user.sh" script

#!/bin/bash

# Add the user
sudo useradd -m clarkeb -s '/bin/bash'
sudo echo -e 'password\npassword\n' | sudo passwd clarkeb

# Set up sudo 
echo "clarkeb ALL=(ALL:ALL) NOPASSWD: ALL" > /etc/sudoers.d/10_clarkeb

# Allow password based login
sed -i 's/PasswordAuthentication no/PasswordAuthentication yes/g' /etc/ssh/sshd_config
sed -i 's/ChallengeResponseAuthentication no/ChallengeResponseAuthentication yes/g' /etc/ssh/sshd_config
service sshd restart

An example Vagrantfile snippet to invoke the above script

  config.vm.define "core01" do |core01|
    core01.vm.provision "shell", path: "create-user.sh"
    core01.vm.hostname = "core01"
    core01.vm.network "private_network", ip: "10.1.1.101"
    core01.vm.provider "virtualbox" do |vb|
    vb.memory = "1024"
      vb.customize ["modifyvm", :id, "--cpus", "1"]
    end
  end
