1. Assessment Goal

Deep Dive and Submission Example for Assessment Goal

A complete treatment of Assessment Goal contains both a technical artifact and a short domain explanation. The artifact can be an inventory, a playbook, a role, a template, a Vault file with dummy values, a CI configuration, or an evidence file. The explanation states why this path was chosen and which alternative was deliberately not used.

Minimal Artifacts for Assessment Goal

submission/
  inventory/hosts.yml
  playbooks/site.yml
  evidence.md
  cleanup.md

For roles or collections, the structure expands:

submission/
  ansible.cfg
  collections/requirements.yml
  inventory/hosts.yml
  roles/<role>/defaults/main.yml
  roles/<role>/tasks/main.yml
  roles/<role>/handlers/main.yml
  playbooks/site.yml
  evidence.md

Grading Expectation for Assessment Goal

A reviewable solution must be understandable to people who did not run it themselves. Screenshots or uncommented terminal output are not enough. Good evidence states context, command, relevant output, and assessment. If a module behaves differently in check mode, that limitation is explicitly documented.

Transfer to Real Teams

In a team context, Assessment Goal is connected to code review, branch rules, CI, role ownership, release notes, and operational approval. Production-like usage also documents ownership, maintenance window, monitoring, alerting, and rollback criteria.

Practical Relevance of Assessment Goal

This section is not just a definition. In the workshop, Assessment Goal is always validated through a concrete flow: inspect inventory, prove target hosts, check the playbook, simulate the change, run the change, evaluate a second run, and document cleanup. This shows whether Ansible really models desired state or merely executes a command successfully once.

Example Flow for Assessment Goal

ansible-inventory -i inventory/hosts.yml --graph
ansible-playbook -i inventory/hosts.yml playbooks/site.yml --list-hosts
ansible-playbook -i inventory/hosts.yml playbooks/site.yml --syntax-check
ansible-playbook -i inventory/hosts.yml playbooks/site.yml --check --diff
ansible-playbook -i inventory/hosts.yml playbooks/site.yml
ansible-playbook -i inventory/hosts.yml playbooks/site.yml

The flow is intentionally complete. In real teams, some steps are automated but not skipped. CI can run syntax checks and linting; the domain review of scope, privileges, secret flows, and rollout risk remains a human engineering task.

Review Criteria for Assessment Goal

• Inventory and patterns are narrower than all unless a reason is documented.
• Modules from ansible.builtin or reviewed collections are preferred.
• Shell or command tasks include changed_when, failed_when, or a clear reason.
• Variables are placed predictably and do not override each other surprisingly.
• Secrets do not appear in plaintext, diffs, debug tasks, or CI logs.
• The playbook can run repeatedly without unnecessary changes.
• Cleanup, fix-forward, or controlled acceptance of the target state is documented.

Common Failure Modes for Assessment Goal

Operations Note for Assessment Goal

For production-like usage, the lab must become a runbook. The runbook states target systems, owners, prerequisites, stop criteria, expected duration, validation, monitoring, and cleanup. Without those details, a playbook is executable but not operationally mature.

This assessment verifies that you can explain, apply, and safely validate Control node, managed nodes, inventory, ad-hoc commands, playbooks, modules.

Official documentation, own notes, ansible-doc, ansible-inventory, syntax check, check mode, and diff mode are allowed. Production hosts, real secrets, and complete model solutions are not allowed.

In the workshop, Hard-Fail Criteria is always validated through a concrete flow: inspect inventory, prove target hosts, check the playbook, simulate the change, run the change, evaluate a second run, and document cleanup. This shows whether Ansible really models desired state or merely executes a command successfully once.

Example Flow for Hard-Fail Criteria

ansible-inventory -i inventory/hosts.yml --graph
ansible-playbook -i inventory/hosts.yml playbooks/site.yml --list-hosts
ansible-playbook -i inventory/hosts.yml playbooks/site.yml --syntax-check
ansible-playbook -i inventory/hosts.yml playbooks/site.yml --check --diff
ansible-playbook -i inventory/hosts.yml playbooks/site.yml
ansible-playbook -i inventory/hosts.yml playbooks/site.yml

The flow is intentionally complete. In real teams, some steps are automated but not skipped. CI can run syntax checks and linting; the domain review of scope, privileges, secret flows, and rollout risk remains a human engineering task.

Review Criteria for Hard-Fail Criteria

• Inventory and patterns are narrower than all unless a reason is documented.
• Modules from ansible.builtin or reviewed collections are preferred.
• Shell or command tasks include changed_when, failed_when, or a clear reason.
• Variables are placed predictably and do not override each other surprisingly.
• Secrets do not appear in plaintext, diffs, debug tasks, or CI logs.
• The playbook can run repeatedly without unnecessary changes.
• Cleanup, fix-forward, or controlled acceptance of the target state is documented.

Common Failure Modes for Hard-Fail Criteria

Operations Note for Hard-Fail Criteria

For production-like usage, the lab must become a runbook. The runbook states target systems, owners, prerequisites, stop criteria, expected duration, validation, monitoring, and cleanup. Without those details, a playbook is executable but not operationally mature.

Production hosts, real secrets, missing scope verification, broad privileges without justification, or no validation after changes cause failure.

11. Examiner Checklist

Deep Dive and Submission Example for Examiner Checklist

A complete treatment of Examiner Checklist contains both a technical artifact and a short domain explanation. The artifact can be an inventory, a playbook, a role, a template, a Vault file with dummy values, a CI configuration, or an evidence file. The explanation states why this path was chosen and which alternative was deliberately not used.

Minimal Artifacts for Examiner Checklist

submission/
  inventory/hosts.yml
  playbooks/site.yml
  evidence.md
  cleanup.md

For roles or collections, the structure expands:

submission/
  ansible.cfg
  collections/requirements.yml
  inventory/hosts.yml
  roles/<role>/defaults/main.yml
  roles/<role>/tasks/main.yml
  roles/<role>/handlers/main.yml
  playbooks/site.yml
  evidence.md

Grading Expectation for Examiner Checklist

A reviewable solution must be understandable to people who did not run it themselves. Screenshots or uncommented terminal output are not enough. Good evidence states context, command, relevant output, and assessment. If a module behaves differently in check mode, that limitation is explicitly documented.

Transfer to Real Teams

In a team context, Examiner Checklist is connected to code review, branch rules, CI, role ownership, release notes, and operational approval. Production-like usage also documents ownership, maintenance window, monitoring, alerting, and rollback criteria.

Practical Relevance of Examiner Checklist

This section is not just a definition. In the workshop, Examiner Checklist is always validated through a concrete flow: inspect inventory, prove target hosts, check the playbook, simulate the change, run the change, evaluate a second run, and document cleanup. This shows whether Ansible really models desired state or merely executes a command successfully once.

Example Flow for Examiner Checklist

ansible-playbook -i inventory/hosts.yml playbooks/site.yml --check --diff
