Jinja Tip! Use selectattr to filter a list of dictionaries based on a matching condition. # Input data interfaces: - { device: 'spine1', interface: 'GigabitEthernet0/0', ip: '10.1.1.1' } - { device: 'spine1', interface: 'GigabitEthernet0/1', ip: '10.1.2.

Jinja Tip: Use Jinja's map to extract specific values from a list of dictionaries. Perfect for pulling out IPs, interfaces, or other attributes within your Jinja templates or Ansible playbooks. Example below: # Input data interfaces: - { device: 'spine1', interface: 'GigabitEthernet0/0', ip: '10.

git diff lets you compare changes between commits, branches, or specific files. It also offers options for summaries and detailed file changes. Here are a few examples: # Compare Changes Between Commits git diff <commit1> <commit2> # Compare changes between two commits. git diff <commit1> <

Introduction In this blog post, we’re going to explore Jinja2, an incredibly versatile tool that’s very useful for network automation. At its core, Jinja2 is a template engine. You can think of it as a stencil in arts and crafts. Just as you might use a stencil to
