bvandeusenandClaude Opus 5.5 8ceb983183 feat(docker): Docker's own status reaches Steward — an empty answer clears a host, a lost one greys it, a demoted manager's swarm rows go (#5152)
CI / lint (push) Successful in 2s
CI / integration (push) Failing after 53s
CI / unit (push) Failing after 1m17s
CI / publish (push) Skipped
The agent (1.9.0) said nothing when Docker could not be asked and nothing
when Docker had no containers, so Steward could tell neither apart from the
other, and kept a host's last containers on screen as running either way.

- Agent: collect_docker returns (status, detail, containers). "ok" sends
  docker: [] when there are none; "unavailable" (no socket, nothing
  listening) and "error" (permission, timeout, bad answer) say why.
  collect_swarm says whether /info answered, and a node that is not a
  manager sends swarm_manager: false. A failed /info says nothing.
- Ingest: an empty docker list is a snapshot; the newest sample's status
  goes to the Docker plugin with the rest.
- docker_host_status (docker_011): per host, status, detail, since and
  last report. A host that never had Docker gets no row.
- An "ok" empty snapshot reaps the host's containers; an error keeps them.
  swarm_manager: false drops the host's swarm services and nodes.
- Docker page: a "Docker not answering" card names each such host, why,
  and since when; its containers read as stale. Duplicate header comment
  in rows.html removed.

bvandeusenandClaude Opus 5.5 bac2859455 feat(docker): Swarm task awareness — replaced tasks, service crash loops, last task error
CI / lint (push) Successful in 3s
CI / integration (push) Successful in 52s
CI / unit (push) Successful in 1m10s
CI / publish (push) Successful in 1m41s
Milestone 465 "Swarm task awareness". Fixes three defects from the live MCP
review #4973:
- #5008 "Swarm task history read as live state"
- #5009 "Crash-loop detection is blind to Swarm services"
- #5011 "Swarm task errors are not captured"

Agent and ingest (agent 1.8.0):
- A manager's agent now reports each service's newest tasks: slot, node,
  desired and current state, Swarm's Err/Message, exit code and time.
- They are stored in docker_swarm_services.tasks_json (migration
  docker_010_swarm_tasks).

Swarm view (pure):
- A task container is "replaced" when Swarm set its task's desired state off
  `running`. Without the task on record, a newer or running task in the same
  slot decides.
- Replaced containers are no longer replicas or crashes.
- Each service gets, from the task records:
  - failures_1h and failures_24h (failed or rejected tasks);
  - crash_looping (Settings → Thresholds count);
  - last_error, in Swarm's own words.

MCP:
- New findings: swarm_service_crash_looping (critical) and swarm_task_failed
  (warning, on a healthy service with a failure in 24h).
- Down and degraded findings name the last task error.
- list_swarm_services carries the failure fields.
- Container rows mark swarm_replaced and give a replaced task no problems.

Web:
- The containers page swarm cards and the Swarm topology page show crash
  loops, recent failures and the last task error.
- The dashboard widget flags a crash loop, and its "failed (24h)" count no
  longer counts a rolling update's killed task.

bvandeusenandClaude Opus 4.8 c95194747d feat(host-agent): collect container logs (incremental push, byte-capped) [M79 step 1]
CI / lint (push) Successful in 7s
CI / unit (push) Successful in 43s
CI / integration (push) Successful in 2m26s
CI / publish (push) Successful in 1m29s
Agent-side of Docker container-log collection (milestone 79). Each interval the
agent fetches new log lines per running container over the local Docker socket,
demuxes the multiplexed stream, and folds sample["docker_logs"] into the same
push as metrics — no inbound channel needed.

- since-cursor per container kept in rate-state; a container's first interval
  seeds from a short tail, then fetches incrementally via ?since=<cursor>
- _docker_request_raw + _demux_docker_logs + RFC3339Nano ts parsing (stdlib,
  TTY/unframed fallback); one row per (stream, ts, line)
- per-batch byte cap with a truncation marker; logs are dropped (never buffered)
  across a backoff so an outage keeps metrics but not stale logs
- docker_logs_enabled (default on) + docker_log_exclude per-host config keys
- AGENT_VERSION 1.6.0 -> 1.7.0

Server ignores the new sample key until the ingest step lands, so this commit is
CI-safe on its own.

bvandeusenandClaude Opus 4.8 a840d6f823 feat(docker): collect + persist /system/df image/disk usage (agent 1.6.0)
CI / lint (push) Successful in 2s
CI / unit (push) Successful in 47s
CI / integration (push) Failing after 2m23s
CI / publish (push) Has been skipped
Backend for the image/disk panel (milestone 77 #942). Agent gains
collect_disk_usage() — one /system/df call (gated on containers existing, so
Docker-less hosts pay nothing), surfacing reclaimable bytes (image size held by
unreferenced images), layers/containers/volumes/build-cache sizes, and the top
50 images by size. Emitted as sample["docker_disk"]; host_agent ingest tracks
the newest sample's copy and hands it to the docker capability as a 5th arg.

New current-state tables docker_disk_usage (one row/host) + docker_images
(per-host image rows), docker_007 migration; ingest upserts the summary and
replaces the image set per host (stale images pruned). Unit tests for the df
parsing/reclaimable math + build_sample gating; integration test for
persistence + image-set replacement.

bvandeusenandClaude Opus 4.8 448258c5b4 feat(docker): agent manager-only swarm collector (AGENT_VERSION 1.5.0)
CI / lint (push) Successful in 3s
CI / unit (push) Successful in 44s
CI / integration (push) Successful in 2m17s
CI / publish (push) Successful in 1m6s
Adds collect_swarm(socket_path) to the host agent. Self-detects a Swarm
manager via /info (Swarm.ControlAvailable) — workers and non-swarm daemons
return None and never touch the manager-only endpoints (one cheap /info call,
no 503s). On a manager it queries /services, /tasks, /nodes and emits
sample["swarm"] = {services, nodes}:

  * services roll desired-vs-running replicas up from the task list (replica
    health isn't on the service object), handle replicated + global mode, strip
    the @sha256 image digest, and carry cross-node task→node placement.
  * nodes normalise role / availability / status + the manager leader flag.

build_sample omits the swarm key entirely off managers, same silent contract
as collect_docker. Unit tests cover manager detection, replica roll-up +
placement (replicated & global), node normalisation, worker silent-skip, and
build_sample wiring.

bvandeusenandClaude Opus 4.8 82c3d2cf36 feat(docker): per-container enrichment — health, restarts, exit code, I/O, grouping
CI / unit (push) Successful in 44s
CI / lint (push) Successful in 2s
CI / integration (push) Successful in 2m20s
CI / publish (push) Successful in 1m10s
First slice of milestone 77 (Docker monitoring depth). Surfaces real per-container
stats beyond basic state, all read-only on the existing push model.

- agent (→1.4.0): collect_docker now inspects each container (health, restart
  count, exit code, OOM) and reads net + block I/O from the stats payload; pulls
  compose project + swarm service/task/node from container labels. Per-container
  inspect+stats calls run over a small bounded ThreadPool so the ~1s-per-stats
  blocking doesn't stretch the sample on a busy host.
- schema (docker_003): additive columns on docker_containers — health, exit_code,
  oom_killed, compose_project, service_name, task_id, node_id, and BigInteger
  net/blk byte counters.
- ingest: persists the enrichment + restart_count (.get keeps older agents working).
- ui: Docker page rows now show health badge, uptime ("up 3d 4h"), restart count,
  exit code (+OOM) for stopped containers, and compose/service grouping label.
- tests: agent helpers (grouping, inspect fields, net/IO sum) + collect_docker
  assembly incl. inspect; integration asserts enrichment round-trips.

bvandeusenandClaude Opus 4.8 7b80552a7d feat(docker): per-host collection via the host agent; drop central scrape
CI / lint (push) Successful in 3s
CI / integration (push) Successful in 2m16s
CI / unit (push) Successful in 4m28s
CI / publish (push) Successful in 1m4s
Docker collection moves off the central single-socket scrape onto the host
agent, giving Docker a real per-host dimension. The Steward host now reports
its own containers like any other host, and same-named containers on different
hosts no longer collide.

- agent: stdlib UDS Docker client (AF_UNIX HTTP/1.1, Connection: close,
  chunked-aware), collect_docker() ports the cpu%/mem math; sample["docker"]
  added best-effort (silent-skip on absent/unreadable socket). AGENT_VERSION
  1.2.0 → 1.3.0; optional docker_socket config key.
- ingest: host_agent ingest hands per-host container snapshots to the docker
  plugin via a new "docker.persist_host_samples" capability (no hard import,
  no-op when docker disabled), inside a SAVEPOINT so a docker failure never
  sinks the host metrics. Resource names are host-scoped ("<host>/<name>").
- schema: docker_containers re-keyed (host_id, name); docker_metrics gains
  host_id; docker_002 migration DROP+recreates (dev-only, rule 122).
- ui: Docker page + widgets grouped by host with host links; new per-host
  Docker panel embedded on the Hosts hub (gated on docker enabled via a new
  enabled_plugins template context). Replaces the SQLite-only strftime
  bucketing with DB-agnostic Python bucketing.
- provisioning: install/provision playbooks add steward-agent to the docker
  group (best-effort) so the agent can read the socket.
- removed central scrape: docker scheduler.py + scraper.py deleted; plugin.yaml
  socket_path/scrape_interval_seconds/include_stopped dropped (plugin 2.0.0).
- tests: agent docker collector units (math, chunked decode, silent-skip,
  sample shape, config) + integration (host-scoped schema + persistence).
