Yesterday, I posted about using Vagrant to learn Ansible, in which I showed you one way to combine these two tools to make it easier to learn Ansible. This is a combination I’m currently using as I continue to explore Ansible. Today, I’m going to expand on yesterday’s post by showing you how to make Vagrant automatically build an Ansible inventory for a particular Vagrant environment.
As you may already know, the Vagrantfile
that Vagrant uses to instantiate and configure the VMs in a particular Vagrant environment is just Ruby. As such, it can be extended in a lot of different ways to do a lot of different things. In my case, I’ve settled on a design pattern that involves a separate YAML file with all the VM-specific data, which is read by the Vagrantfile
when the user runs vagrant up
. The data in the YAML file determines how many VMs are instantiated, what box is used for each VM, and the resources that are allocated to each VM. This is a design pattern I’ve used repeatedly in my GitHub “learning-tools” repository, and it seems to work pretty well (for me, at least).
Using this arrangement, since I Continue reading
If you’ve watched any of the recent Wireless Field Day presentations, you know that free wireless is a big hot button issue. The delegates believe that wireless is something akin to a public utility that should be available without reservation. But can it every really be free?
Let’s take a look at other “free” offerings you get in restaurants. If you eat at popular Mexican restaurants, you often get free tortilla chips and salsa, often called a “setup”. A large number of bars will have bowls of salty snacks waiting for patrons to enjoy between beers or other drinks. These appetizers are free so wireless should be free as well, right?
The funny thing about those “free” appetizers is that they aren’t really free. They serve as a means to an end. The salty snacks on the bar are there to make you thirsty and cause you to order more drinks to quench that thirst. The cost of offering those snacks is balanced by the amount of extra alcohol you consume. The “free” chips and salsa at the restaurant serve as much to control food costs as they do to whet your appetite. By offering cheap food Continue reading
