Starting the VM¶
You can test the provisioning/deployment using Vagrant. This requires
Vagrant 1.3+. The Vagrantfile is configured to install the Salt Master and Minion inside the VM once
vagrant up. The box will be installed if you don’t have it already.:
The general provision workflow is the same as in the previous provisioning guide so here are notes of the Vagrant specifics.
Provisioning the VM¶
Set your environment variables and secrets in
conf/pillar/local.sls. It is OK for this to
be checked into version control because it can only be used on the developer’s local machine. To
finalize the provisioning you simply need to run:
fab vagrant deploy
The Vagrant box will use the current working copy of the project and the local.py settings. If you want to use this for development/testing it is helpful to change your local settings to extend from staging instead of dev:
# Example local.py from traffic_stops.settings.staging import * # Override settings here DATABASES['default']['NAME'] = 'traffic_stops_local' DATABASES['default']['USER'] = 'traffic_stops_local' DEBUG = True
This won’t have the same nice features of the development server such as auto-reloading but it will
run with a stack which is much closer to the production environment. Also beware that while
conf/pillar/local.sls is checked into version control,
local.py generally isn’t, so it will
be up to you to keep them in sync.
Testing on the VM¶
With the VM fully provisioned and deployed, you can access the VM at the IP address specified in the
Vagrantfile, which is 22.214.171.124 by default. Since the Nginx configuration will only listen for the domain name in
conf/pillar/staging/env.sls, you will need to modify your
/etc/hosts configuration to view it
at one of those IP addresses. I recommend 126.96.36.199, otherwise the ports in the localhost URL cause
the CSRF middleware to complain
REASON_BAD_REFERER when testing over SSL. You will need to add:
<domain> matches the domain in
conf/pillar/staging/env.sls. For example, let’s use
In your browser you can now view https://dev.example.com and see the VM running the full web stack.
Note that this
/etc/hosts entry will prevent you from accessing the true dev.example.com.
When your testing is complete, you should remove or comment out this entry.
