Third-party commands

Before we finish up looking at Ansible commands, there are a few different third-party commands I would like to cover, the first of which is ansible-inventory-grapher.

The ansible-inventory-grapher command

The ansible-inventory-grapher command by Will Thames uses the Graphviz library to visualize your host inventories. The first thing we need to do is install Graphviz. To install this on macOS using Homebrew, run the following command:

$ brew install graphviz

Or, to install Graphviz on Ubuntu, use:

$ sudo apt-get install graphviz

Once installed, you can install ansible-inventory-grapher using pip:

$ sudo install ansible-inventory-grapher

Now that we have everything installed, we can generate the graph using the hosts file we used earlier in the chapter:

ansible01 ansible_host=46.101.92.240
ansible02 ansible_host=159.65.63.218
ansible03 ansible_host=159.65.63.217
ansible04 ansible_host=138.68.145.116
