SEC.01

The playbook

The run starts read-only: the recon probes decide what happens next. The steps that follow are adapted to the distribution and state found — a real machine is rarely clean.

1. 01reconlogrotate present + version
2. 02recondo any files match the pattern?
3. 03reconare these logs already managed? (duplicate = logrotate error) → do not add one
4. 04recondoes a config with the same name exist? do not overwrite it
5. 05reconfolder owner: non-root or group-writable → su directive
6. 06reconis logrotate scheduled (timer or cron)?
7. 07actInstall logrotate (if missing)verify
8. 08actWrite /etc/logrotate.d/${app_name}verify
9. 09actDry-run testverify

What it verifies

Each step ships its own check. The run only moves on when the check passes, so what the recipe reports as done is what is actually on the server.

1. 01verifyInstall logrotate (if missing)Verified bylogrotate --version 2>&1 | head -1
2. 02verifyWrite /etc/logrotate.d/${app_name}Verified bylogrotate -d /etc/logrotate.d/${app_name} 2>&1 | grep -ci error
3. 03verifyDry-run testVerified bylogrotate -d /etc/logrotate.d/${app_name} 2>&1 | grep -c 'considering log'

Guardrails

Non-negotiable instructions the run must respect, whatever it finds on the server.

Variables

What you choose before launching — the recipe fills in the rest.

SEC.05

How a recipe runs in Servor

Servor is zero-knowledge: the platform cannot execute anything on its own. When you launch this recipe, a run reads the reconnaissance, plans the steps and asks for your approval. Each approved command is signed by your browser — with a key the server never sees — then relayed verbatim to the agent, which verifies the signature locally before executing.

Deploy on Servor button

Maintain Log rotation or a project that needs it? Put this button in your README or on your site: one click and your users install it on their own server.
