INFRASTRUCTURE AS CODE & AUTOMATION

Ansible Playbook Boilerplate Generator

Generate starting-point Ansible playbooks for common Linux admin tasks. Each playbook runs read-only pre-checks first, makes idempotent changes, supports dry runs with --check --diff, and can wrap the change in a block / rescue that reports failures clearly.

$ Generated as a starting point. Run with –check –diff against a test host first.

Runs in your browser. Nothing you enter is sent anywhere.

1. Playbook Specifications

Target Operating System: Linux playbooks detect the OS family from gathered facts, so one playbook works on both RHEL-family and Debian-family hosts.

Task Template:

Target Host Group: An inventory group or host pattern, e.g. infra_servers or web01,web02. Letters, digits and _ . - : * ! , only.

Error Handling: Used by the LVM and SSH templates. The rescue section reports what failed; it does not undo storage changes.

Generated Playbook (playbook.yml)

Review before use.

Suggested run order:

In check mode the read-only pre-checks and verification commands still run (they set check_mode: false and changed_when: false), so their output is real. Tasks that change the host only report what they would do. On a host where a package is not installed yet, later tasks in a –check run may report errors because the install was only simulated.

Before you run a generated playbook

Edit the vars: section. Every value there is an example (volume names, sizes, user names, NTP servers, thresholds).
Run --syntax-check, then --check --diff with --limit set to one test host, and read the output.
Run storage and SSH changes in a maintenance window. For storage changes, confirm no backup job is running against the volume.
Lines starting with # DISRUPTIVE: or # CHANGES CONFIG: mark the tasks that change the host.
Reference: Ansible check mode and diff mode, community.general.lvol.

Estimates and generated commands are a starting point. Review and test before running in production.
