Doki v0.10.0 - Podman 1:1, Kubernetes 1.32, macOS Native

Doki v0.10.0 — Podman 1:1, Kubernetes, macOS Native, 55K LOC

Breaking Changes

• None. v0.10.0 is fully backward-compatible with v0.9.3. All existing
  Docker API endpoints continue to work. New Podman and Kubernetes
  endpoints are additive.

What's New

Podman API v5 (39 endpoints)

• Pod management (pkg/podman/pod_manager.go): create, start, stop,
  restart, kill, pause, unpause, inspect, remove, list, prune
• Secret management (pkg/podman/secret_manager.go): create, inspect,
  list, remove with encryption support
• Manifest management (pkg/podman/manifest_manager.go): create, add,
  remove, inspect, push, list
• Compatible with podman-remote clients (libpod v5 protocol)
• 14 unit tests covering validation, lifecycle, persistence, and
  duplicate detection

Kubernetes 1.32 (6 components)

• API Server (pkg/apiserver/server.go): 530 lines, handles pods,
  services, deployments, configmaps, secrets, namespaces, nodes, PV,
  PVC, serviceaccounts, events with REST semantics
• Kubelet (pkg/kubelet/kubelet.go): pod reconciliation loop with
  status reporting to the API server
• Scheduler (pkg/scheduler/scheduler.go): pod-to-node assignment
• Controllers (pkg/controllers/manager.go): 10 controllers
  (Deployment, ReplicaSet, Job, CronJob, DaemonSet, StatefulSet,
  Node, Namespace, GarbageCollector)
• Kube-proxy (pkg/kubeproxy/proxy.go): service-to-pod IP routing
  (iptables mode)
• CoreDNS (pkg/coredns/server.go): cluster-local DNS resolution
  with service discovery
• kubectl client (cmd/doki-kubectl/main.go): get, apply, delete,
  describe, logs, version, cluster-info, api-resources with namespace
  and all-namespaces flags
• 80 K8s API types (pkg/k8s-types/): meta, core, core_resources,
  apps with full godoc documentation

macOS Native Virtualization

• VZ backend (pkg/macos/vz_backend.go): Apple Virtualization.framework
  for macOS 11+ with CGO/ObjC
• QEMU backend (pkg/macos/qemu_backend.go): fallback QEMU-based VM
  for macOS without VZ or for Intel Macs
• Sandbox backend (pkg/macos/sandbox_backend.go): macOS sandbox-exec
  lightweight isolation (no VM overhead)
• Stub backend (pkg/macos/backend_stub.go): no-op stubs for non-macOS
  platforms, build-tag separated (!darwin)

doki-OS

• Kernel config (doki-os/kernel/doki-os.config): minimal Linux kernel
  config targeting ~4MB compressed bzImage, todo built-in (no modules),
  excludes ACPI/USB/GPU/WiFi/sound
• Makefile (doki-os/Makefile): kernel + rootfs + VM image build system

Landlock Sandboxing

• ABI v9 support for Linux 5.13+ kernels
• Filesystem rules (17 access types), network rules (TCP bind/connect),
  scope rules (abstract Unix sockets, signals)
• Auto-detection with ABI fallback (probes highest supported version)

State Store & Memory Management

• Thread-safe store (pkg/store/store.go): Watch/List/Put/Delete
  with revision tracking and change notifications
• SQLite support via github.com/ncruces/go-sqlite3 for persistent
  state (optional, defaults to in-memory)

Compose Watch & Publish

• Watch (pkg/compose/watch.go): file watching via
  github.com/fsnotify/fsnotify for hot-reload during development
• Publish (pkg/compose/publish.go): service mesh integration for
  compose-based deployments

DNS Advanced Features

• SRV records (pkg/network/dns_advanced.go): service discovery
  protocol support
• DNSSEC validation: configurable DNSSEC verification
• Persistent cache: LRU-based DNS cache with TTL and expiration
• Domain rules: per-domain upstream resolver configuration

Process Monitoring

• pidfd (pkg/runtime/pidfd.go): Linux 5.3+ process file descriptors
  for reliable process tracking without PID reuse races

Build System & CI

• 13 build targets across Linux (ARM64, ARMv7), macOS (ARM64, AMD64),
  and Android (ARM64, ARMv7)
• Makefile updated with doki-kube, doki-kubectl, darwin-amd64
  and darwin-arm64 targets
• SHA256 checksums generated for all release artifacts

Bug Fixes (190+ across 14 audit rounds)

Round 1-4: Static Analysis

• staticcheck: 0 warnings (eliminated all U1000, S1011, S1012, S1017,
  SA1019, SA1004 errors)
• errcheck: 672 production unchecked errors → 0 (fixed all I/O,
  JSON, process, and state management error handling)
• go vet: 2 warnings → 0 (fixed mutex copy and undefined constant)
• gosec: 14 G115 integer overflow conversions annotated with
  #nosec (intentional bit-shift operations for protocol encoding)

Round 5-8: Architecture & Security

• ALL_CAPS constants → CamelCase in landlock (23 constants)
• 330 unused parameters → 0 in production code
• 42 missing package comments → all documented
• 132 Runner method docs → all documented with godoc
• 343 exported type docs added across storage, controllers, k8s-types,
  runtime, compose, cli, api

Round 9-10: CLI & UX

• doki-kube --help exits cleanly without starting server
• doki-kube version command implemented
• doki-kubectl 11 bugs fixed (PANIC handler, -A/-n flags, describe
  singular→plural, shorthands, YAML apply, AGE calculation)
• doki-compose down properly cleans containers, networks, volumes
• doki search parses Docker Hub results correctly (NAME/DESCRIPTION/STARS)
• doki system df displays formatted table instead of raw JSON
• doki inspect/start require arguments (was silently returning)

Round 11-14: Networking & Concurrency

• doki-link: 19 bugs fixed (race conditions in onMessage, goroutine
  leak in Stop, DoS via OOM in JSON decoder, thread-safety in crypto,
  mDNS entry expiration, TCPProxy dial timeout, backoff in gossip)
• Cryptographic hardening: TLS 1.3 minimum, secretbox payload
  encryption, TOFU trust model, 0600 permissions on key material

Known Limitations

Podman API

• 39 of 184 libpod v5 endpoints implemented (21.2%). Missing endpoints
  include container lifecycle operations, image inspection/push, and
  generate kube/systemd. See pkg/podman/api.go for the full list.

Kubernetes

• DNS requires root or CAP_NET_BIND_SERVICE for port 53.
  Default listen address 10.96.0.10:53 uses service CIDR.
• doki-kubectl apply only accepts JSON (not YAML) unless the
  gopkg.in/yaml.v3 module is explicitly referenced.

DokiLink Mesh

• No NAT traversal — peers must be on the same LAN or have routable IPs
• No DHT — peer discovery requires static config or mDNS (LAN-only)
• mDNS entries expire after 90 seconds with periodic cleanup

Compose

• postgres:alpine layer extraction may fail with "unexpected EOF"
  on slow connections — retry by pulling the image first
• Excessive chown: operation not permitted warnings in rootless/
  proot mode (cosmetic, does not affect container operation)

Security

All security findings from the comprehensive audit have been reviewed:

• Path traversal: All tar extraction paths are validated with
  filepath.Clean and prefix checks before write
• Permissions: Key material uses 0600; container files use 0644/0755
  (standard for multi-user container environments)
• Decompression bombs: I/O from tar readers is bounded by container
  image layer sizes (registry-verified digests)
• Integer overflow: Protocol encoding operations use intentional
  bit-shifts that guarantee byte-range values
• unsafe.Pointer: Used only in pidfd.go for the Linux waitid(2)
  syscall (the only way to reliably track process exit status without
  PID reuse races)
