# ### General
# 
# This Vagrant file spinns up an infrastructure dependencies for developer environment such as:
#  * Nomad (NAT to localhost and available over private network as node)
#  * Consul (NAT to localhost)
# 
# In order to run specific versions feel free to change `BASE_IMAGE`, `NOMAD_VERSION` and `CONSUL_VERSION` variables.
# In case you need to have nomad node to be available on specific IP, change `VM_HOSTONLY_STATIC_IP` var.
# 
# ### Prerequirements
# You should have installed Vagrant and any of VM provider (VirtualBox 5.2+ as recommended) 
# 
# ### Usage
# 
# Just run in current folder the following:
# 
# `$ vagrant up`
# 
# It will build the VM and run NOMAD and CONSUL processes reporting logs with corresponding prefixes.
