YAML lab 45 bonus XP

Configure the IAM-02 pipeline

Start labRead the room

Objectives

Turn the agreed requirements into the pipeline configuration file. The grader reads the YAML and checks each stage: collectors, schedule, record schema, custody, the empty-population rule and alerting.

Agreed requirements

control: IAM-02
identity source:     cursor pagination, retry up to 5 times
cloud_config source: token pagination, retry up to 5 times
schedule:            daily at 02:00 UTC
record fields:       control_id, source, collected_at, subject, value, raw_hash
timestamps:          taken at collection time
hash:                sha256 of the raw response
storage:             append-only, keep 400 days
empty population:    fail the run
alert:               iam-team, on failure

Checks the server runs (7)

  • Names the control
  • Both collectors paginate and retry as agreed
  • Runs daily at 02:00 UTC
  • Record carries all six fields
  • Collection timestamp, SHA-256, append-only, 400 days
  • Empty population fails
  • Owner is alerted on failure

Check names are all you see here: the expectations that decide pass or fail, and the reference solution, stay on the server.

Step-by-step hints

The guided walkthrough, in full. It is free: no XP cost, and it does not touch the paid hint ladder or the reveal gate.

  1. Step 1

    Identify and collect

    Fill the control id, then each source's pagination style and retry limit.

    Names the controlBoth collectors paginate and retry as agreed

  2. Step 2

    Schedule

    Express the run time with the hour and the time zone.

    Runs daily at 02:00 UTC

  3. Step 3

    Shape and protect the record

    List every record field, say which stage the timestamp comes from, name the hash algorithm and set storage.

    Record carries all six fieldsCollection timestamp, SHA-256, append-only, 400 days

  4. Step 4

    Fail safely and tell someone

    Decide the empty-population outcome and who hears about a failure.

    Empty population failsOwner is alerted on failure
