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`.
Successfully complete this lab by achieving the following learning objectives:
- Update the Vagrantfile
config.vm.synced_folderoption 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.
- Test the Vagrant Environment and Check the Sync
Deploy the Vagrant environment:
We can SSH into the guest container to see that the sync worked:
vagrant ssh ls /opt/wanderer/ exit
- 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
vim app/views/index.ejs To-Do
Save and exit; notice the output from Vagrant.
Kill the auto-sync process:
Stop the container:
