Jon Chery e92b18197c feat(P01): SSH-push transport layer — connection pool, retry, fan-out, idempotent writes (REQ-073)
P01 — Load-bearing replacement for v0.8 mTLS transport (R-001).

Transport (internal/sshpush/transport.go, REQ-073):
- Transport struct with sync.Map connection pool (reuse *ssh.Client per peer).
- Exec with context timeout (10s default) + retry (100ms x2 cap 5s max 5
  attempts, +/-25% jitter — same backoff as v0.8 transport/retry.go).
- ReadFile, WriteFile (atomic heredoc + mv), Close.
- sshDialer + sshSession seams for testability. TOFU host-key verification
  reuses proxmox.TOFUHostKeyCallback. security.Flock for known_hosts.

Fan-out (internal/sshpush/fanout.go):
- ExecAll, WriteAll with errgroup + SetLimit semaphore (default 8 per I-B-001).
  Per-peer errors collected, don't cancel the group.

Idempotency (internal/sshpush/idempotency.go, C-18):
- WriteFileIdempotent: SHA-256 compare via ssh sha256sum; skip if content
  matches (written=false). Content-addressed idempotency replaces the v0.8
  X-Orca-Idempotency-Key header (C-18 capability map).

Tests: in-process fake SSH server (ssh.NewServerConn NoClientAuth ed25519)
for e2e + interface seams for pure-logic. 93.0% coverage. 20 packages pass.

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)
