From b1ebf17d7c60de4273826818b925accbcd28a7e5 Mon Sep 17 00:00:00 2001 From: Jon Crall Date: Tue, 16 Jun 2026 15:01:29 -0400 Subject: [PATCH 01/96] Add backend-agnostic lease ledger (leasing/controller redesign) Begin the infer-stack leasing/controller redesign. Adds a new `infer_stack.leasing` subpackage, kept cleanly separate from the existing stateless compiler (resolver/validator/renderer): - models.py: EndpointRequest / Lease / DeploymentGroup, compatibility_key (structural identity), vllm_structural/ollama_structural, and capacity_satisfies (subsumption, not equality). - store.py: SqliteStore (WAL + busy_timeout + BEGIN IMMEDIATE) so the find-or-create-group critical section is race-safe across processes. - ledger.py: acquire/release/renew/sweep/reclaimable_groups/status. Demand is a COUNT(DISTINCT lease_id) over protecting leases (computed, not stored); groups flip LIVE<->IDLE on demand; soft-TTL is the crash backstop. Coalescing grain is "the thing that gets a process": per-model for vLLM, per-daemon for Ollama (host config is the structural key, tags accumulate in the group's served map). 17 unit tests + 3 xdoctests pass; ruff clean. Bumps version 0.6.1 -> 0.7.0. Design: aiq-eval-runner dev/infer-stack-redesign-critique.md.

The full critique + staged plan lives +in the *parent* repo at `aiq-eval-runner/dev/infer-stack-redesign-critique.md` +(grounded in the two real consumers: aiq-eval-runner's Incubilate/Contextual +Drag and eval_audit's HELM/kwdagger path). User explicitly asked to start on a +new branch and bump versions; chose sqlite for the store (open question #1 in +that doc). This is Phase 1's foundation. + +**What I built (branch `dev/leasing-controller`, version 0.6.1 -> 0.7.0):** +A new backend-agnostic `infer_stack/leasing/` subpackage — the *controller* +half, deliberately separate from the existing stateless compiler +(`resolver`/`validator`/`renderer`), which is kept intact. +- `models.py`: `EndpointRequest` (catalog-resolved input), `Lease`, + `DeploymentGroup`, the `compatibility_key` (pure structural identity hash), + `vllm_structural`/`ollama_structural` builders, and `capacity_satisfies` + (subsumption, not equality). +- `store.py`: `SqliteStore` — autocommit + WAL + `busy_timeout`, with a + `transaction()` context manager that issues `BEGIN IMMEDIATE` so the + find-or-create-group critical section is race-safe across processes. +- `ledger.py`: `Ledger.acquire/release/renew/sweep/reclaimable_groups/status`. + Demand = count of *protecting* leases (ACTIVE and not past TTL), computed by a + SQL `COUNT(DISTINCT lease_id)` join, not stored. Groups flip LIVE<->IDLE on + demand; teardown of IDLE groups is left to the future reconciler per reclaim + policy. +- 17 unit tests + 3 xdoctests, all passing; ruff clean; existing fast suite + unaffected. Ran via `uv run --extra tests --with xdoctest` (xdoctest is in + pyproject addopts but not the tests extra — had to add it; the system python + has no pytest). + +**Key design decisions / reflections:** +- The central reframe is compiler-vs-controller. I resisted bolting acquire/TTL + onto the resolver; the ledger is a separate stateful layer with its own store. + This is what makes "last render wins" go away: desired state becomes the union + of live leases, not one mutated profile. +- Coalescing grain = "the thing that gets a process": per-model for vLLM, + per-daemon for Ollama. Modeled uniformly by making the Ollama structural key + the *host config* (no tag), so many tag endpoints collapse to one group whose + `served` map accumulates the tags. This kept one code path for both engines. +- Compatibility is structural-equality + capacity-subsumption, NOT a single + equality key. A 32k deployment serves an 8k request; the reverse makes a new + group. Sharing policy is handled in the ledger (dedicated => always new), + deliberately kept OUT of the hash so the key stays a clean deployment identity. +- TTL is soft and is the crash backstop: protection lapses by time immediately + in the demand query; `sweep()` only *materializes* the EXPIRED state for + status/reclaim. A job killed by SIGKILL (no release) is recovered by TTL. + +**Uncertainties / risks / what might break:** +- The ledger is pure bookkeeping with NO backend yet — nothing realizes, + probes, or tears down deployments. `AcquireResult.groups` is the handoff + point for the next slice (reconciler + 4-method backend protocol + readiness + with the Ollama pull/warmup rung). +- `EndpointRequest` is hand-built in tests; the catalog.yaml parser that + produces them (new schema: models/endpoints/hosts/bundles) is not written. +- Cross-process concurrency relies on `BEGIN IMMEDIATE` + WAL + busy_timeout; I + reasoned it through and unit-tested the single-process invariants, but did not + write a true multi-process stress test. If contention shows up, that's where + to look first. +- Group `spec` is taken from the first creating request; coalesced requests' + specs are assumed compatible by construction. Correct given the compat key, + but worth remembering when the backend starts consuming `spec`. + +**Confident about:** the object model and the coalescing/TTL/demand semantics +(well covered by tests), the layering (controller cleanly separated from the +compiler, no edits to existing modules beyond the version bump), and that this +is the right minimal foundation for Phases 1-4. + +**Next steps:** catalog.yaml parser -> EndpointRequest; the Reconciler + Backend +protocol (`realize/teardown/observe/probe_ready`) with Compose first (reuse +`_first_fit`, `_wait_until_ready`, the live LiteLLM router refresh); then the +`acquire`/`release`/`run`/`status` CLI emitting the `contracts.py` env-file. diff --git a/infer_stack/__init__.py b/infer_stack/__init__.py index 677eff3b..e4100e1a 100644 --- a/infer_stack/__init__.py +++ b/infer_stack/__init__.py @@ -1,2 +1,2 @@ __all__ = [] -__version__ = '0.6.1' +__version__ = '0.7.0' diff --git a/infer_stack/leasing/__init__.py b/infer_stack/leasing/__init__.py new file mode 100644 index 00000000..49cea9e5 --- /dev/null +++ b/infer_stack/leasing/__init__.py @@ -0,0 +1,50 @@ +"""Lease ledger: the stateful controller half of infer-stack. + +See ``dev/infer-stack-redesign-critique.md`` (aiq-eval-runner) for the design. +This subpackage is backend-agnostic bookkeeping — ``acquire``/``release``/ +``renew`` over a shared sqlite store with demand reference-counting, same-model +coalescing, and soft-TTL reclaim.

Alias endpoints (two names, same model+runtime) resolve to the same compat key and therefore coalesce onto one deployment, validating "compat key = deployment identity, not endpoint name". 15 catalog tests (incl. ledger integration), 32 leasing tests total, 4 xdoctests, ruff clean.

These are the + payloads the (not-yet-written) backend will consume to realize a process. + +**Risks / unknowns:** still no backend — `spec` shapes are my best guess at what +compose/kubeai renderers will need and may shift when the reconciler lands. The +new catalog schema is not yet wired to any CLI or migrated from the existing +`config.yaml`/profiles (the legacy `_legacy_profile_to_stack` migration is +future work). No backwards-compat shim yet between the old and new catalogs. + +**Next:** the Reconciler + a 4-method Backend protocol +(`realize`/`teardown`/`observe`/`probe_ready`), testable first with a fake +backend, then a Compose implementation reusing the existing placement/readiness +machinery. diff --git a/infer_stack/leasing/__init__.py b/infer_stack/leasing/__init__.py index 49cea9e5..6edf45f0 100644 --- a/infer_stack/leasing/__init__.py +++ b/infer_stack/leasing/__init__.py @@ -9,6 +9,13 @@ from __future__ import annotations +from .catalog import ( + Catalog, + CatalogError, + EndpointSpec, + ModelSpec, + RuntimeHostSpec, +) from .ledger import ( AcquireResult, Ledger, @@ -32,13 +39,18 @@ __all__ = [ 'AcquireResult', + 'Catalog', + 'CatalogError', 'DeploymentGroup', 'EndpointRequest', + 'EndpointSpec', 'GroupState', 'Ledger', 'Lease', 'LeaseState', + 'ModelSpec', 'ReleaseResult', + 'RuntimeHostSpec', 'Sharing', 'SqliteStore', 'SweepResult', diff --git a/infer_stack/leasing/catalog.py b/infer_stack/leasing/catalog.py new file mode 100644 index 00000000..dd900a1b --- /dev/null +++ b/infer_stack/leasing/catalog.py @@ -0,0 +1,370 @@ +"""The serving catalog: the declarative input to the leasing controller. + +This is the new, version-controlled, lifecycle-free description of *what can be +served* (the redesign demotes the old "profiles" singleton; see +``dev/infer-stack-redesign-critique.md`` §9).

This Protocol is the only surface a real backend (Compose, KubeAI) must implement. - controller.py: `Controller(ledger, backend)` with the desired-vs-actual reconcile loop, `wait_ready`, and thin `acquire`/`release`. Reconcile sweeps the ledger first so TTL self-enforces (a crashed job's lease stops protecting once its TTL elapses). Desired = LIVE groups + keep-warm idle groups; teardown falls out of the diff, no separate STOPPED state needed. Readiness waits are scoped to the endpoints a lease requested, so a node acquiring one Ollama tag doesn't block on a sibling tag's health. 11 controller tests (incl. catalog integration), 43 leasing tests total, 5 xdoctests, ruff clean.

The focused + renderer emits a compose dict straight from groups and *reuses + `profile_runtime.vllm_args`* for the genuinely tricky vLLM flag-building. +- `ComposeBackend` is converge-style: place (pinned from a persisted sidecar) -> + render -> write compose.yml + sidecar -> `docker compose up -d + --remove-orphans`. observe() parses `docker compose ps --format json` and maps + running services back to group ids via the sidecar. Docker is an injected + `run(args)->str` seam. +- Controller `reconcile` now prefers `backend.converge(desired)` when present + (whole-union convergence) and falls back to the per-group realize/teardown + loop for Memory/Null backends. Computed realized/torn_down from before/after + observe() diffs. +- Wired `--backend compose` into the CLI (`detect_inventory`, data_root state + dir, `--allowed-gpus`). 90 leasing/CLI tests, 7 xdoctests, ruff clean. Tested + with a *stateful* FakeDocker (`up` reflects the rendered compose file, `ps` + returns it, `--remove-orphans` drops gone services) so converge->observe is + coherent end to end without docker. + +**Decisions / reflections:** +- Per-group `realize`/`teardown` never fit compose's one-file model; rather than + contort the protocol I added an optional `converge` the controller detects via + `hasattr`. ComposeBackend therefore implements converge/observe/probe_ready + (not realize/teardown) — it duck-types into the controller's converge path. +- `--remove-orphans` *is* teardown: converge always renders only the desired + groups, so a dropped group's service becomes an orphan and is removed. No + separate teardown docker call needed. +- Placement stability via the persisted sidecar: converge feeds current + assignments as `pinned`, so adding/removing a group never migrates a running + model's GPUs. + +**Risks / unknowns (for when you test on the GPU host):** +- Readiness is only "container running" this slice. `acquire --backend compose` + returns once the vLLM *container* is up, NOT once the model has finished + loading/serving. Real generation-probe readiness + Ollama pull/warmup come in + slice 3. +- The env-file `base_url` is still the `--base-url` placeholder (default + :14042).

This adds an executable harness that runs the same scenarios, asserts the wiring, and writes one self-contained results dir (report.md + per-step logs + the run's rendered compose/litellm/.env) to rsync back. - lib.sh: step/assert DSL; each step -> one results.jsonl record; no set -e. - render_report.py (stdlib): per-step JSON emitter + report.md assembler with a Correctness/Efficiency/Ergonomics rollup and failures-first log tails. - catalog.yaml: committed (validated via Catalog.load/resolve_names). - tests/: non-serving tiers (env, dry-run, ergonomics, negatives) + GPU serving tiers (single-vllm, coalescing, dedicated/F5, TTL, run-wrapper, ollama, concurrency) + always-run cleanup. - run.sh: ./run.sh [--gpu] [--only ...]; fresh data dir per run inside the results dir; prints the rsync line. Non-serving tiers smoke-tested locally against the null backend (16/16).

So "where my weights live" can + only be set via `INFER_STACK_DATA_DIR` / `--data-dir`, hence the `~/.bashrc` + line in §1a. *Proposal:* a first-class `infer-stack config set data_dir

` + (or have leasing honor `config.yaml`'s storage root) so storage is part of + the durable user config, not a shell export. + +3. **No endpoint-addressed teardown for standing services.** `serve` has no + env-file, so stopping it means copying a session id out of `infer-stack + leases`. *Proposal:* `infer-stack release --endpoint big-chat` (or + `infer-stack unserve big-chat`) to release standing leases by the name you + served them under. + +4. **Open WebUI is unmanaged.** The legacy stack rendered Open WebUI + its + postgres; the leasing model dropped the UI, so it's a hand-run `docker run` + here. That's arguably correct separation (leasing serves the API; the UI is a + client), but it costs the one-command UX. *Proposal:* an optional + `infer-stack ui up` (or a `ui` entry the catalog can render) that wires the + base_url + managed key automatically. + +5. **`HF_TOKEN` has no managed slot.** Gated models need it in the shell env at + `serve` time (Compose interpolates `${HF_TOKEN:-}`); there's nowhere durable + to put it next to the managed `LITELLM_MASTER_KEY`. *Proposal:* + `infer-stack secrets --set HF_TOKEN=…` writing the managed `.env` (which + Compose already auto-loads). + +None of these block the demo; they're where the next ergonomic polish would pay +off.

A tier-60 acquire left its lease ACTIVE (a not-ready/uncleaned acquire keeps its lease), so its qwen-small group stayed LIVE in the ledger; every later reconcile re-realized it on GPU 0 and starved ollama / run-exit-code / the concurrency tier. - reset_between_tiers now also wipes the ledger (ledger.db + wal/shm) and downs by project name, so each GPU tier starts from zero leases/groups. - run() prints a '… still running (Ns)' heartbeat every 20s (and reaps the heartbeat's sleep child) so long cold-starts don't look hung. - New cleanup.sh: down the 'infer-stack' project (+ stragglers by label) and optionally wipe a run's ledger — for recovering after a Ctrl-C. - leasing-followups.md: record the underlying product issues (not-ready acquire leaks an active lease; re-acquire spawns a new group instead of reviving an idle one; ledger-vs-reality drift re-realizes leaked LIVE groups).

2001 From: Jon Crall Date: Thu, 18 Jun 2026 12:06:32 -0400 Subject: [PATCH 35/96] cli phase 2: `config` submodal + durable settings (backend, data_dir) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit `infer-stack config …` gains init/show/set/get/edit alongside the existing `paths`, backed by a new settings.yaml in the config dir: config set backend compose # default backend for acquire/serve/run config set data_dir /data/infer-stack # where docker-mounted state lives These are now honored, killing two ergonomic smells: - `data_root()` consults `data_dir` (override > $INFER_STACK_DATA_DIR > setting > XDG default), so storage no longer has to be re-exported each shell. - the leasing `--backend` default is now None and resolves explicit-flag > `config set backend` > "null", so a configured host stops repeating `--backend compose`. settings live in paths.py (load/save/get_setting) to avoid import cycles. (`config init` writes the settings skeleton; the legacy config.yaml `init`/ `setup` move under `legacy` in a later phase.) 4 tests; suite 224 + 4.

`secrets` alias MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit `infer-stack secret get|set|list` manages the compose backend's managed .env: - `secret get [KEY]` / `secret list` — what `secrets` did (print value / export lines) - `secret set HF_TOKEN=hf_…` — write a secret to the managed .env (which docker compose auto-loads), so a gated model's token can be set once *before* `serve`, no manual export. Merges non-destructively (LiteLLM key preserved); creates the .env if absent. Closes the HF_TOKEN ergonomic smell. Top-level `secrets` stays as an alias for `secret get` (script compatibility for `$(infer-stack secrets KEY)`). 2 tests; suite 230.

The Compose backend renders an `open-webui` service in front of the LiteLLM gateway whenever the front door is up, so `serve chat` brings up a working UI (default http://127.0.0.1:13000) with no hand-run `docker run`. Its spec is a pure function of inputs that don't change with the model set (it talks to the `litellm` service at a fixed URL with the stable baked key), so converge leaves it running across model add/remove/switch — only the gateway is recreated on a routing change, so the UI never blinks (the legacy property, preserved). Opt out with `--no-ui` or `config set ui false`; serve/acquire print the UI URL. `infer-stack test `: leasing-native smoke test — one real chat completion to the alias through the gateway (managed key applied), prints latency + reply or an actionable failure with non-zero exit. The demo keeps `curl` for the raw form. `infer-stack env` replaces the `secrets` alias: prints the managed env-file path first (`source "$(infer-stack env)"`), a single value with `env KEY`, or all as exports with `--export`. The `secret get|set|list` modal is unchanged. LiteLLM front-door config gains `router_settings` (num_retries/timeout/cooldown_time/allowed_fails) so the brief warmup window where an upstream is still loading its model is retried/self-healing instead of surfacing as client 500s / loud `Connection error.

The output was profile-first. Reframe status leasing-first: lead with backend / data dir / config dir, then the leasing setup (catalog with model/endpoint counts, settings) and the leasing summary. `config.yaml` is reported as `legacy config` (it's the pre-leasing profile artifact). The "get started" hint only prints when *nothing* is set up, and then points at `config init` / `catalog init` / `serve`. The legacy profile/rendered/components detail still prints when a `config.yaml` exists. Also fixed the KubeAI status error to say `infer-stack legacy setup`. Tests updated (status before-setup now asserts the leasing guidance; KubeAI error asserts `legacy setup`); e2e 20_ergonomics asserts `backend:` + no "Not initialized" and the `env` missing-error message. 240 pass, ruff clean.

Kills the phantom-`live` group + infinite wait that the demo hit on yardrat. - Legible vLLM container/service names: vllm-- (was the opaque vllm-), so `docker ps` / `nvidia-smi` make sense without infer-stack. The group-id suffix keeps names unique + correlatable with `leases`. Ollama daemons keep their id-name (one daemon hosts many models). - `leases` shows actual vs desired: a `running` column (backend.observe) and a `gpus` column (on / →slated), best-effort so dry-run/docker-less degrade to "unknown" rather than erroring. - Render and apply are separate, lease-free verbs (`render`, `apply`); serve/acquire = declare+render+apply+wait; `--no-apply` stages (declare + render, no up). Declares refcount, reconciles are idempotent — removes the duplicate-lease trap without making acquire/serve idempotent. - Top-level `name: infer-stack` baked into the rendered compose, so a plain `docker compose -f up -d` lands in the same project as the tool — "drop infer-stack and run docker yourself" == `apply`. - Demo: add two Qwen-family models (cross-family side-by-side). Docs: expand the leasing verbs' --help (docstrings + `serve`/`leases`/top-level epilogs). 267 tests pass; ruff clean on the changed files.

Running the demo on yardrat showed why that's wrong: `release --all` silently rewrote docker-compose.yml and recreated a keep-warm model (the one-time container-rename migration landed on a release), with no preview. Now release/evict/apply also build the backend interactively and gate the diff on a TTY (--yes skips, non-TTY auto-applies) — nothing mutates the compose file or runs docker without that step. release/evict batch all their ledger changes into a single converge, so you're asked at most once instead of once per lease. Decline semantics: declining an acquire rolls the lease back (as before); declining a release/evict records the ledger change but leaves docker untouched — `infer-stack apply` then applies it (consistent with the render/apply split). Adds a shared _ApprovalMixin (--yes/-y), _declined_exit(), CHANGELOG + demo notes, a --yes plumbing test, and a dev/journals/claude.md entry. 268 tests pass; ruff clean on changed files.

Fix: the backend records `last_unplaced`; + controller.acquire rolls the lease back and raises `PlacementError` if a + *just-requested* group landed unplaced. This also dissolved the "phantom live" + display — the bad lease never persists. Key realization: `live` is *desired* + (ledger), never *observed*; the two were conflated in `leases`. +- **leases shows desired vs actual.** Added `running` (backend.observe) and + `gpus` (`plan()`, read-only placement; `→N` = slated) columns.

Surfaced as a flag on + the declare verbs (`serve|acquire --no-apply`, stage) plus lease-free `render` + / `apply` reconcile verbs. The crux we reasoned through with the user: `apply` + writes *no* infer-stack tracking state — all of it (ledger intent + sidecar + placement) is written at declare/stage time — so "drop the tool and `docker + compose up` yourself" is a true equivalent.

charset=UTF-8 Content-Transfer-Encoding: 8bit `infer-stack tui` opens a live dashboard (lease + group tables: desired state vs running, GPUs) that auto-refreshes, with key-bound controls: s serve (pick a catalog endpoint via a modal), d release the selected lease, a release-all, e evict the selected idle group, r refresh, q quit. - infer_stack/tui.py: the Textual App (InferStackTUI) + ServeModal + run_tui(). Reads via the controller/ledger on the UI thread (cheap); mutations converge off-thread (@work(thread=True)) so docker up/down doesn't freeze the monitor, then marshal a status + refresh back. loguru narration is silenced while the TUI owns the terminal. Cursor position is preserved across refreshes. - TuiCLI (`infer-stack tui`), registered top-level; textual is an opt-in extra (`pip install "infer-stack[tui]"`), lazily imported with an install hint. - SqliteStore made thread-safe (check_same_thread=False + an RLock serializing write transactions) so the shared ledger connection works from the TUI's converge worker — required for any multi-threaded user, not just the TUI. Headless pilot tests (mount + populate + open-serve-modal; release action drops the lease via the worker). pyproject `tui` extra + uv.lock; demo + CHANGELOG. 286 pass; ruff clean on changed files.

e888eff1f618d5954a937fb6edca279b97953ca0 Mon Sep 17 00:00:00 2001 From: Jon Crall Date: Thu, 18 Jun 2026 23:36:45 -0400 Subject: [PATCH 63/96] =?UTF-8?q?tui:=20multi-pane=20dashboard=20=E2=80=94?= =?UTF-8?q?=20catalog,=20leases/groups,=20live=20switchable=20logs?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Grow the TUI from two tables into a real dashboard: - Catalog pane (sidebar): lists endpoints (name/model/engine/reclaim) + models; select an endpoint and press s/Enter to request a lease. This is the "see the catalog so you can serve" surface (replaces the serve modal). - Leases + Groups panes: the live ledger view (desired state vs running, GPUs), auto-refreshing, cursor preserved across refreshes. - Logs pane: tails `docker compose logs -f` into a RichLog; a Select dropdown switches between all services and a specific one (litellm, open-webui, vllm-*, reverse-proxy). The service list syncs from the on-disk compose file as models come and go. The log process is injectable (proc_factory) so the streaming path is exercised headless via Textual pilot — no docker needed in tests. Layout: catalog | (leases / groups / logs) with a status bar + footer. Mutations still converge off the UI thread. Tests: panes list catalog/leases/groups; serve-from-catalog creates a lease; logs stream from an injected fake source. CHANGELOG + demo updated. 288 pass; ruff clean on changed files.

Quiet `round $surface` borders that brighten to $accent only on focus, so the active pane is a gentle cue rather than everything shouting; pane titles via border_title. Nord theme for a muted palette. Generous padding + margins between panes for breathing room. - Resizable panes: `[`/`]` narrow/widen the catalog sidebar, `-`/`+` shrink/grow the logs pane (hidden bindings; clamped). Leases/groups share the remaining space so logs resize is meaningful. - A summary line under the header (models / endpoints / leases active / groups running) and a one-line key hint in the status bar. Layout unchanged in spirit: catalog sidebar | (leases + groups over logs). Same ids/behaviour, so the existing pilot tests hold; added a headless resize test. 304 pass; ruff clean on changed files.

Seeding is a pure function `inventory x pool -> catalog`: - templates/suggestion-pool.yaml: the curated pool, lifted from the *real* entries of the legacy default-vllm-models.yaml (the speculative Qwen3.5/3.6/Gemma4 fixtures dropped) plus the two models the demo serves, keeping the intrinsic sizing schema (min_vram, preferred_gpu_count, context_window, defaults). - leasing/suggest.py: the typed pool loader + the join. Filters to models that fit, sizes max_model_len / gpu_memory_utilization to the host GPU, pins --dtype=half on pre-Ampere GPUs, tensor-parallels multi-GPU models, and keeps the largest fitting model warm. - `catalog suggest`: renders by default (writes nothing, pipe-friendly); --apply merges additively into the catalog (existing entries kept unless --force). Honors --simulate-hardware / --allowed-gpus / --skip-display-gpus, so it plans offline for hardware you don't have. Pre-Ampere detection currently sniffs the GPU name; adding compute_cap to the nvidia-smi query in hardware.py would make it exact (follow-up). Tests: 10 engine tests + 4 CLI tests; full suite green.

Continuation of the leasing +TUI work. + +User intent (compressed): make the TUI usable by a newcomer and stop it feeling +janky. Concretely: (1) an orange / white / very-dark-gray theme; (2) "feel +faster or more responsive"; (3) a real bug — `docker compose` progress was +overwriting the top-left of the screen for a moment when serving; (4) turn the +logs pane into a docker *tab* (logs **or** ps); (5) require `config init` before +launch, and if there are no models offer a button that runs the new `suggest` +tool to populate the catalog; (6) wizards to add models/endpoints; (7) more +explanatory text so new users can intuit what's going on; (8) drag-to-resize +panes. + +What I did (all in `infer_stack/tui.py`, `tests/test_tui.py`, plus a small +`TuiCLI` change in `cli/commands_leasing.py`): + +- Theme: registered a custom `textual.theme.Theme` (`infer-orange`) — dark-gray + canvas, white text, one warm orange accent that only shows on the focused + pane's border. Replaces the borrowed `nord`. +- Bleed bug: root cause was `_default_docker_run` = `check_output` (captures + stdout, lets **stderr** through), and `docker compose up -d`/`down` write all + progress to stderr → straight onto the full-screen terminal. Fix lives at the + TUI layer (didn't touch the CLI's runner, where stderr-to-terminal is + desirable): on mount I wrap `backend.run` with a `capture_output=True` runner + that routes the noisy verbs' stderr into the logs pane and swallows `ps` + polling. Felt cleaner than changing the shared default. +- Responsiveness: the periodic refresh used to call `backend.observe()` + (`docker compose ps`) **on the UI thread** every 3s — a real freeze. Split + into `_collect()` (thread-safe, no widgets) + `_render()` (UI thread); + `on_mount` does one synchronous `_refresh_now()` for an instant first paint + (and so the headless tests still see data after a single `pause()`), while the + interval + `r` + post-mutation refresh go through a `@work(thread=True)` + worker. The bleed fix doubles as responsiveness (no terminal corruption). +- Docker tab: logs pane is now a `TabbedContent` — "Logs" (the existing Select + + RichLog, IDs preserved) and "Status · ps" (a DataTable fed by a best-effort + compose-ps parse in the collect worker). +- Onboarding: `TuiCLI` now hard-requires `settings.yaml` (i.e. `config init`) + and *tolerates a missing/empty catalog* via a new `_load_catalog_for_tui` + (returns an empty Catalog + the path it would write). Empty state shows a + help line steering to Suggest/add. Suggest (`g`/button) calls the other + agent's now-committed `leasing.suggest.suggest_catalog` + `commands_catalog` + load/save helpers (imported, never edited), merges, reloads in place. +- Wizards: `_AddModelScreen` / `_AddEndpointScreen` ModalScreens with Inputs; + results written through `commands_catalog._load_raw/_save_raw` (which validate) + and the catalog reloaded. `m` / `n` or sidebar buttons. +- Drag-resize: a tiny `_Divider(Static)` that captures the mouse and reports + axis-delta to a callback (`_drag_sidebar` / `_drag_logs`), alongside the + existing `[` `]` / `-` `+` keys. Vertical bar between sidebar/main, horizontal + bar between tables/docker. + +State of mind / risks: as always, none of this has been *eyeballed on a real +terminal* — headless pilot proves it composes, tabs, resizes, serves, streams, +and writes the catalog, but the orange theme's actual feel, the drag ergonomics, +and (critically) whether the stderr-capture fully kills the corner-bleed are +only verifiable by running `infer-stack tui` on a GPU host (yardrat). The +suggest path in particular only runs under real hardware detection. Confident +about: the threading split (clear win, observe was blocking), the +backend.run-wrapping approach (localized, reversible), and that I stayed off the +other agent's files (their suggest CLI is committed at 4ef5147; I only import). +8 TUI tests + full prior suite (303) green; ruff clean on changed files. + +Takeaways: (1) when a full-screen UI drives a subprocess, capture *both* streams +at the UI boundary — stderr is the usual screen-corrupter, and the fix belongs +at the UI layer, not in the shared runner where stderr is wanted. (2) Keep a +synchronous first paint even after moving refresh to a worker: it makes the app +feel instant *and* keeps headless tests deterministic without `wait_for_complete` +gymnastics. (3) For a tool newcomers land in, downgrade "missing config" from an +error to an empty-state-with-a-button — the absent catalog is the start of the +funnel, not a failure. diff --git a/dev/leasing-demo.md b/dev/leasing-demo.md index 20521ba2..d34e0a06 100644 --- a/dev/leasing-demo.md +++ b/dev/leasing-demo.md @@ -164,12 +164,17 @@ infer-stack stack logs -f # follow startup (Ctrl-C to stop) (alias: infer-stac (or `→N` for one that's slated but not started yet) — so it's obvious when something is still warming up vs truly live. -> **Prefer a live dashboard?** `infer-stack tui` opens a multi-pane Textual UI: +> **Prefer a live dashboard?** `infer-stack tui` opens a multi-pane Textual UI +> (run `infer-stack config init` once first): > a **catalog** pane to pick an endpoint and serve it (`s`/Enter), live -> **leases** + **groups** tables, and a **logs** pane that tails `docker compose -> logs -f` (a dropdown points it at one service or all).

They are not -- they are real models released Feb-Apr 2026 (Qwen3.5 Mar 2, Gemma 4 Apr 2), and the legacy HF ids match the real model pages. They were excluded on a stale existence judgment, not on fit: 9 of the 14 fit a single 24 GiB GPU (an RTX 3090) -- qwen3.5 0.8B/2B/4B/9B, qwen3.6-35b-a3b-fp8, and all four Gemma 4 sizes. Add all 14 (8 Qwen3.5, 2 Qwen3.6, 4 Gemma 4), big ones included -- the pool is hardware-blind and `suggest` filters per box, so a 3090 sees the fitting subset while a multi-GPU host also gets the 122B/72B/MoE variants. Pool now spans 26 models. Tests assert the families are present with their real HF ids and lock in the exact 3090 fit set.

The pre-leasing resolver + validator (and the cli/compose, cli/probes shims that only the deleted commands used) are gone; cli/context is carved down to the two helpers the leasing surface needs (_apply_path_overrides, effective_inventory). config paths now reports only current locations (config_root, settings.yaml, catalog.yaml, data_root, the leasing ledger/compose files) instead of the old profile artifacts.

Collapse and a fixed-height drag bar can't coexist on one pane in Textual (the explicit height defeats collapse), so the leases|deployments drag bar (lsplit) is dropped in favor of collapse there; the catalog stays drag-sized (endpoints|models csplit) since you act on it constantly.

One-time setup + +```bash +infer-stack config init +``` + +Pick the **compose** backend and a data directory (where weights/state are +bind-mounted). Then make the stack lean: + +```bash +infer-stack config set litellm false +``` + +This is the persistent default; you can also decide per-invocation with +`serve … --no-litellm` / `--litellm`. + +### 2. Declare the Ollama daemon + +A runtime host is the long-lived daemon (one daemon serves many tags): + +```bash +infer-stack catalog host add local-ollama \ + --engine ollama \ + --gpu 0 1 \ # pin to GPU 0 and 1 (both 1080 Tis) + --keep_alive 30m # how long a model stays resident after last use +``` + +`--gpu` is exactly the GPU restriction you wanted: the daemon only ever sees the +indices you list (it becomes the container's `CUDA_VISIBLE_DEVICES`). Use +`--gpu 0` to keep it off your display card, `--gpu 0 1` to let ollama use both +(it will split a model across them when one card can't hold it). + +Other optional knobs: `--num_parallel`, `--max_loaded_models`, +`--context_length`, `--image` (a custom ollama image). + +### 3. Declare one anchor model + +`serve` needs at least one endpoint to start the daemon. Declare a small default +— it gets pulled automatically so the box is useful the moment it's up: + +```bash +infer-stack catalog endpoint add chat \ + --engine ollama --host local-ollama --model llama3.2:3b +``` + +For ollama, `--model` is just the **ollama tag** (`llama3.2:3b`, `qwen2.5:7b`, +…) — no separate `catalog model add` needed. The alias `chat` is what shows up +in Open WebUI. (Omit the name and it auto-names `llama3.2-3b-1`.) + +You can review what you built any time: + +```bash +infer-stack catalog show +``` + +### 4. Bring it up + +```bash +infer-stack serve chat +``` + +This places the daemon on your GPUs, writes the compose project, runs +`docker compose up`, pulls the `llama3.2:3b` tag, and waits until it's serving. +On a terminal you'll see the compose diff and a confirm prompt first +(`--yes` to skip). + +### 5. Use it — and let ollama manage the rest + +Open **http://localhost:13000**. The `chat` model is already there. To add more, +go to **Settings → Admin → Models** (or the model picker's *Manage* / +*Pull a model* control) and pull any tag — `qwen2.5:14b`, `gemma2:9b`, whatever. +The daemon downloads it, keeps it on disk, and loads it on demand. You never +have to touch the catalog again for day-to-day model juggling. + +--- + +## Managing the stack + +```bash +infer-stack status # holistic overview: backend, GPUs, leases, URLs +infer-stack ps # docker compose ps for the stack +infer-stack logs # tail service logs +infer-stack stack down # stop everything +``` + +To change the daemon's GPUs or keep-alive later, re-run `catalog host add +local-ollama … --force` and `infer-stack serve chat` again — the daemon (and its +on-disk models) is recreated with the new pinning; Open WebUI stays up. + +--- + +## Variants + +### Keep LiteLLM too (OpenAI base_url for scripts) + +Leave `litellm` on (the default). You then also get an OpenAI-compatible gateway: + +```bash +infer-stack config set litellm true # or just don't turn it off +infer-stack serve chat +infer-stack env # prints base_url + API key for clients +``` + +Open WebUI uses the gateway for chat **and** keeps the native Ollama connection +for pull/manage — best of both.

Leverages yardrat's 2nd GPU (the display-attached GPU 1). Fix: an Ollama daemon pinned to a non-zero GPU silently ran on CPU. The docker device reservation (device_ids) exposes only the pinned GPU and the NVIDIA runtime renumbers it to 0 inside the container, but _ollama_service also set CUDA_VISIBLE_DEVICES to the *host* index, so pinning to GPU 1 pointed at a device that didn't exist in-container. Pin by the reservation alone, like vLLM. Updated the unit test that had enshrined the bug. e2e harness (dev/e2e_tests): * 86_ollama_lean (new) — --no-litellm: no gateway, Open WebUI wired straight at the daemon's native API, tag still pulled, chat hits the daemon directly, status reports the UI URL. * 88_gpu_pinning (new) — pin a daemon to GPU 1 (--include-display-gpus): assert device_ids=[1], no host-index CUDA_VISIBLE_DEVICES, and it runs ON the GPU (ollama ps != 100% CPU). Catches the bug above on real hardware. * 85_ollama — now asserts Open WebUI gets BOTH connections (gateway OpenAI + native Ollama) when the gateway is on. * catalog.yaml — add an ollama host pinned to GPU 1 + smol-ollama-gpu1 endpoint. * inspect.py (new) — compose-file inspector so the tiers assert wiring without brittle YAML grepping.

The flag made acquire fast-fail with "unrecognized arguments", so 88_gpu_pinning never rendered and inspect.py read a stale compose (wrong device_ids). Dropped the flag from 88_gpu_pinning and from the pre-existing 45_both_gpus (broken the same way); GPU 1 is placeable without it. Updated the README GPU note. * 86_ollama_lean asserted the Open WebUI URL appears in `infer-stack status`, but status doesn't print it (acquire/serve do). Assert the UI front-door port from the rendered compose instead (inspect.py now prints open-webui host_port) and just sanity-check `status` exits 0. Verified inspect.py output matches every assertion against rendered compose.
