Syncing Files with Vagrant
When using Vagrant, being able to sync applications, infrastructure, and other important files between your workstation and the resulting environment is paramount. It ensures that any changes we make to our working environment will persist after a `vagrant destroy` — after all, the Vagrant environment is ephemeral. In this hands-on lab, we will specifically explore syncing our host and guest directories using the `rsync` implementation by updating our `Vagrantfile`.

Challenge
Update the Vagrantfile
-
Use the
config.vm.synced_folder
option to set up file syncing based on the parameters from the instructions:Vagrant.configure("2") do |config| config.vm.box = "fgrehm/trusty64-lxc" config.vm.define "app" do |app| app.vm.provider :lxc do |lxc| lxc.container_name = 'app' end end config.vm.synced_folder "/home/cloud_user/wanderer/app", "/opt/wanderer", type: "rsync", id: "wanderer-app", rsync__auto: true end
-
Save and exit.

-
Challenge
Test the Vagrant Environment and Check the Sync
-
Deploy the Vagrant environment:
vagrant up
-
We can SSH into the guest container to see that the sync worked:
vagrant ssh ls /opt/wanderer/ exit
-
-
Challenge
Test the Auto-Syncing Process
-
Since we are using
rsync
, auto-synced must be turned on:vagrant rsync-auto &
-
Take note of the process ID output.
-
Update the application; here changing
Do This!
toTo-Do
:vim app/views/index.ejs To-Do
-
Save and exit; notice the output from Vagrant.
-
Kill the auto-sync process:
pkill PID_OUTPUT
-
Stop the container:
vagrant halt
