Data Playbook v0 - origins

Data playbooks was created to replace various snippets of code I had lying around. They were all created to ensure repeatability of some menial task, and generally followed a similar structure of load something, process it and save it. (Process network data into GIS tools, network audits & reporting on router & NMS output, Extract IETF standards to complete SOCs, read my bank statements into my Excel budgeting tool, etc.)

For many of these tasks I have specific processing code (tasks_x.py, loaded with modules: [tasks_x] in the playbook), but in almost all cases input & output tasks (and configuring these names etc) are common. The idea of the modular tasks originally came from Home Assistant, where I started learning Python and the idea of "custom components" to add your own integrations, although one could argue this also has similarities to Ansible playbooks.

In many cases I have a 'loose' coupling to actual file names, using Everything search (!es search_pattern in the playbook) to resolve a search pattern to the correct file used for input.

It has some parts in common with Ansible Playbooks, especially the name was chosen after I was introduced to Ansible Playbooks. The task structure has been updated in 2019 to match the Ansible Playbooks 2.0/2.5+ format and allow names. This format will also be easier to introduce loop mechanisms etc.

Comparison to Ansible Playbooks

Data playbooks is intended to create and modify variables in the environment (similar to inventory). Data playbooks starts with an empty environment (although you can read the environment from various sources inside the play). Although new variables can be created using register: in Ansible, data playbook functions requires the output to be captured through target:.

Data playbook tasks are different form Ansible's actions:

• They are mostly not idempotent, since the intention is to modify tables as we go along,
• they can return lists containing rows or be Python iterators (that yield rows of a table)
• if they dont return any tabular data (a list), the return value will be added to the var table in the environment
• Each have a strict voluptuous schema, evaluated when loading and during runtime (e.g. to expand templates) to allow quick troubleshooting

You could argue I can do this with Ansible, but it won't be as elegant with single item hosts files, gather_facts: no and delegate_to: localhost throughout the playbooks. It will likely only be half as much fun trying to force it into my way of thinking.
