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. 01reconDocker present and active (prerequisite)
  2. 02reconregistry already deployed? existing registry_data volume (to reuse)?
  3. 03reconport 5000 free?
  4. 04reconcredentials already generated?
  5. 05reconreverse proxy present (Caddy or Nginx) for TLS if a domain is provided
  6. 06actGenerate the passwordverify
  7. 07actCreate the htpasswd file (bcrypt)verify
  8. 08actRun the registryverify
  9. 09actTLS reverse proxy (only if a domain is provided)verify

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. 01Generate the passwordVerified bystat -c %a /opt/registry/admin_password
  2. 02Create the htpasswd file (bcrypt)Verified bygrep -c '^${username}:\$2y\$' /opt/registry/auth/htpasswd
  3. 03Run the registryVerified bycurl -s -o /dev/null -w '%{http_code}' http://127.0.0.1:5000/v2/; echo; curl -s -o /dev/null -w '%{http_code}' -u ${username}:$(cat /opt/registry/admin_password) http://127.0.0.1:5000/v2/
  4. 04TLS reverse proxy (only if a domain is provided)Verified bycurl -s -o /dev/null -w '%{http_code}' -u ${username}:$(cat /opt/registry/admin_password) https://${domain}/v2/

Guardrails

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

If Docker or the compose plugin is missing: stop and tell the user to run the "Docker Engine" recipe first (do not install it on the fly). Never expose a registry without TLS + auth: it listens on 127.0.0.1:5000, remote access goes through the TLS reverse proxy. Never delete the registry_data volume. Say where to read the password: /opt/registry/admin_password. Do not log the password.

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.

  • 01Read-only reconnaissance before any change
  • 02Every command signed by your browser, approved by you
  • 03Each step verified before the run moves on, every run kept in the history
