ops-warden

SSH Certificate Authority and certificate lifecycle manager for the ops fleet. Signs short-lived certs for adm / agt / atm actors and exposes the cert_command interface consumed by ops-bridge and other tooling.

See SCOPE.md for boundaries and wiki/AccessManagementDirective.md for policy.

Install

uv sync
uv tool install .

Or run without installing:

uv run warden --help

Quick start (local backend)

# One-time: generate a CA key (keep mode 600, never commit)
ssh-keygen -t ed25519 -f ~/.ssh/ops-ca-user -C "Ops SSH User CA" -N ""

# Configure warden (~/.config/warden/warden.yaml) — see wiki/OpsWardenConfig.md
warden inventory add agt-example --type agt --principal agt-example
warden sign agt-example --pubkey ~/.ssh/id_ed25519.pub
warden status agt-example
warden scorecard

Production uses the vault backend against OpenBao or HashiCorp Vault (Vault-compatible SSH secrets engine API). See wiki/OpsWardenConfig.md.

Development

uv sync
uv run pytest              # unit tests (integration excluded)
uv run pytest -m integration   # requires ssh-keygen in PATH
uv run ruff check .
