+# Kick start with vagrant
+
+[Vagrant](https://www.vagrantup.com/intro/index.html) is popular tool used for helping local development and testing. Here are some tips that has been very useful for me when setting up and using Vagrant
+
+## Use box file
+
+A common practice when using vagrant is to use shell script to provision the vm, for example:
+
+in Vagrantfile
+
+{% highlight ruby %}
+vm4.vm.provision "shell", path: "VagrantProvision/provision_centos7.sh"
+{% endhighlight %}
+
+in provision_centos7.sh
+
+{% highlight Bash shell scripts %}
+
+#!/bin/bash
+set -x
+
+sudo rpm -iUvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
+sudo yum update -y && sudo yum install -y net-tools wget ansible python-docker-py python-prettytable
+
+# More setup ...
+
+{% endhighlight %}
+
+While This is helpful to make sure the changes made to the base image are versioned and can be share within teams, it can be slow when a base box needs to get build every time.
+
+A better way would be to build the box file which just need to build once which will speed up the vm start up time significantly.
+
+First, let's define our base image in Vagrantfile:
+
+Here we use centos 7 as an example:
+
+{% highlight ruby %}
+
+config.vm.define "base" do |base|
+  config.vm.provider :virtualbox do |vb|
+    vb.name = "base"
+  end
+  base.vm.box = "centos/7"
+  # config local network
+  base.vm.network "private_network", ip: "192.168.3.9"
+  base.vm.provision "shell", path: "VagrantProvision/provision_centos7.sh"
+end
+
+{% endhighlight %}
+
+Sample script for building box file :
+
+{% highlight Bash shell scripts %}
+
+echo "creating dir to hold box file ..."
+mkdir Boxes
+
+echo "making sure base vm is down ..."
+vagrant destroy -f base
+
+echo "starting base vm ..."
+vagrant up base
+
+echo "starting cleaning up old box file ..."
+rm -f Boxes/centos7.box
+vagrant box remove --force  file://Boxes/centos7.box
+
+echo "packing the new image into Boxes/centos7.box"
+vagrant package --base base -o Boxes/centos7.box
+
+echo "cleaning up base vm ..."
+vagrant destroy -f base
+
+{% endhighlight %}
+
+After the box file is build, change the vagrant file to refer to the local box file:
+
+{% highlight ruby %}
+vm1.vm.box  = "file://Boxes/centos7.box"
+{% endhighlight %}
+
+Here we can skip the provisioning step when start the vm since all the changes needed as pre-build in the box file
+
+
+## Set up http proxy for vm
+
+## Separate vm definition from Vagrant code
+
+## Use vagrant cacher to speed up provision time
