README

This is a framework to integrate ServiceNow data into a CI/CD pipeline.

   with Context("/table/mytable", validator=Record) as ctx:
      # if needed, filter records, grouping, further validation... can be done
      update_yaml("test.yaml", ctx.data)

We assume that the workflow is standard:

1. Get one resource from ServiceNow (e.g. "/table/incident")
2. Validate the data received
3. Store the data
4. Commit and push all changes

Nb: if needed, this library provide lower level utilities.

How it works

• Every variables are taken from environment variables. (see below)
• This will create a timestamp.txt file with the last run. This file must be cached for the next run
• This will automaticly clone the target repository
• The data is retrieved and validated against a validator. We recommend to use pydantic library for the validation
• ctx.data will contain a list a dict containing at least sys_id entry that is unique

Environment variables

Here is the list of the possible environment variables

client.Client

• GIT_AUTHOR_NAME: author of the commit
• GIT_AUTHOR_EMAIL: email of the commit author
• GIT_BRANCH: The branch to edit (create it if it doesn't exist). Default to the default branch
