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. 01recondoes the user already exist? do not overwrite it
  2. 02actCreate the userdestructiveverify
  3. 03actInstall the SSH keyverify
  4. 04actAdd to the sudo groupdestructiveverify

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. 01Create the userVerified byid ${username} >/dev/null 2>&1 && echo ok
  2. 02Install the SSH keyVerified bygrep -cF "${pubkey}" /home/${username}/.ssh/authorized_keys
  3. 03Add to the sudo groupVerified byid -nG ${username} | grep -c sudo

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.
