Jon Chery 797bc2f412 feat(P02): Proxmox SSH join + OrcaOperator role + sudoers
orca node join --type proxmox bootstraps a remote Proxmox VE 8/9 host
via SSH (REQ-050, REQ-051). The password is used only for initial auth;
subsequent access uses the deployed orca SSH key (D-031).

Changes:
- go.mod: add golang.org/x/crypto v0.54.0 (ssh + ssh/knownhosts + ed25519)
  bump x/sys to v0.47.0, add x/term (indirect)
- internal/certpaths: SSHKeyPath, SSHPubPath, KnownHostsPath (D-037)
- internal/security/sshkey.go: GenerateOrLoadSSHKey (Ed25519, PKCS8 PEM,
  0600/0644 modes, idempotent load per D-036)
- internal/proxmox/bootstrap.go: BootstrapProxmox SSH dance:
  1. Generate/load SSH key
  2. SSH dial (password + knownhosts.New TOFU per D-035)
  3. Deploy pubkey to ~orca/.ssh/authorized_keys (idempotent)
  4. useradd -m orca (idempotent)
  5. pveum role add OrcaOperator --privs 'VM.Audit Datastore.AllocateSpace SDN.Use'
  6. pveum user add orca@pam (AD-019: PAM realm, not @pve)
  7. pveum acl modify / -user orca@pam -role OrcaOperator
  8. Write /etc/sudoers.d/orca (AD-020: NOEXEC on pct/qm, no NOEXEC on
     apt-get/dpkg, pvesh EXCLUDED — API execute bypasses NOEXEC)
  9. visudo -cf validation (abort on failure)
  All steps idempotent; audit-logged.
- internal/cli/node.go: --type/--host/--ssh-user/--password/--ssh-port/
  --proxmox-user/--proxmox-role flags; joinProxmox() wires to
  proxmox.BootstrapProxmox + registers node with kind=proxmox, os=pve.
  Password zeroed after use (D-031).
- tests: sshkey generate/load round-trip, idempotency, file modes;
  proxmox sudoers content (NOEXEC/NOPASSWD/pvesh-excluded),
  privilege set, validation; node join flag wiring

Orca

Offline/CLI-first orchestration engine inspired by HashiCorp Nomad, far simpler than Kubernetes.

Status

v0.1: Foundation — see .ciagent/ROADMAP.md for the 6-phase plan.

Pillars

  • Simplicity — single binary, minimal dependencies
  • AI-first — CLI designed for both humans and AI agents
  • Offline-first — no cloud dependencies
  • CLI-first — primary interface is the command line
  • Security before features — NFRs ship before new functionality
  • Bug fixes before features — stability is paramount
  • NFRs before features — observability and auditability first

Quickstart

Install (1-liner)

# User-level install (binary at ~/.local/bin/orca, state at ~/.orca)
curl -fsSL https://git.cloudinit.dev/coreci/orca/raw/branch/main/scripts/install.sh | bash

# System-level install (binary at /usr/local/bin/orca, state at /root/.orca)
curl -fsSL https://git.cloudinit.dev/coreci/orca/raw/branch/main/scripts/install.sh | sudo bash -s -- --system

# Pin a specific version
curl -fsSL https://git.cloudinit.dev/coreci/orca/raw/branch/main/scripts/install.sh | bash -s -- --version v0.4.2

Then initialize local state and verify:

orca init          # creates ~/.orca/ (or /root/.orca with --system)
orca version       # prints version info
orca --help        # show all subcommands

Build from source

make build         # Build binary to ./bin/orca
./bin/orca init    # Initialize local state
./bin/orca version # Verify

Update in place

Re-running the installer updates the binary while preserving your config, database, and certificates in the namespace dir:

curl -fsSL https://git.cloudinit.dev/coreci/orca/raw/branch/main/scripts/install.sh | bash
# → "updated orca from v0.4.1 to v0.4.2"

Subcommands

Command Description Status
orca version Print version info Phase 1
orca init Initialize local orca state Phase 1 (stub)
orca status Show orca daemon status Phase 1 (stub)
orca node Node management (join, leave, list) Phase 2
orca job Job management (run, list, stop, logs) Phase 3

Development

make build      # Build binary to ./bin/orca
make test       # Run tests with race detection
make lint       # Run golangci-lint
make fmt        # Format code
make release    # Build + create Gitea release (Phase 6)
