When the Docker daemon is unreachable the node snapshot collection fails and
returns empty sets. The preflight rules read those empty sets as "resource
absent", so a stack referencing an external network or volume got false "not
found" blockers while real host-port and container_name conflicts went
undetected.
Add a nodeStateAvailable flag to the preflight context, mirroring the existing
sourceReadable gate. The six node-state rules now suppress themselves when the
snapshot could not be collected, and a single info advisory reports that the
node-state checks were skipped so a clean pass during an outage is not mistaken
for full coverage.
The effective-model read surfaces (Networking, Dossier/Anatomy, Storage,
and Compose Doctor) avoid environment, label, and command values, but
docker compose config resolves any ${VAR} interpolation before the model
is parsed, leaving no provenance. A secret interpolated into a structural
field (a bind path, network name, published port, or extra_hosts entry)
is therefore returned resolved. That value is already readable at the
same stack:read scope through the stack's files, so this documents the
caveat rather than changing behavior.
- Reword the "secret-safe / never shows a secret value" claims on the
Networking, Dossier, Storage, and Doctor docs pages, and add a
canonical note to the Environment and Secrets Guardrails page steering
secrets to environment:/env_file: injection.
- Make the matching code comments honest in effectiveAnatomy,
composeNetworkInspector, effectiveModel (extra_hosts), and the
effective-anatomy route.
* feat: add Compose Doctor preflight checks for stacks
Add an on-demand, advisory preflight that renders a stack's effective
Compose model with `docker compose config` and runs a registry of
deterministic checks before deploy, surfacing findings grouped by
severity (blocker, high, warning, info) with a remediation for each.
Findings cover unset env vars, host-port conflicts on the node, broad
0.0.0.0 exposure, missing bind-mount paths, a mounted Docker socket,
privileged and host networking, moving image tags, missing restart
policy and healthcheck, Swarm-only deploy fields, missing external
networks or volumes, and container_name collisions.
The report is node-scoped and stored as the last run per stack, and the
route auto-proxies to the active node so a remote stack is checked on
the node that owns it. A new Doctor tab on the stack detail panel runs
preflight and shows the grouped findings, with a severity dot on the tab
when the last run has blocker or high findings. The tab is gated on a
compose-doctor capability so older nodes hide it.
No environment value is ever stored, returned, or logged: only env key
names and structural facts are read, and render failures surface a
generic message or the missing required-variable names, never raw
stderr.
* fix: scroll the stack tab strip when its tabs overflow
Adding the Doctor tab can push the per-stack Anatomy tab strip past the
panel width on narrower layouts. Make the tab row scroll horizontally
with subtle edge fades that appear only while there is more to scroll in
that direction, so a panel wide enough to show every tab is unchanged.
* fix: add clickable arrows and wheel scroll to the stack tab strip
Hiding the scrollbar left mouse users with no way to scroll the
overflowing tab row: a vertical wheel does not move a horizontal overflow
and native rows do not drag-scroll. Replace the passive edge fades with
clickable chevron arrows shown only when the row overflows that edge, and
translate a vertical wheel over the row into horizontal scroll.
* fix: inline the path-injection barrier in renderConfig
CodeQL's path-injection check does not credit the wrapped isPathWithinBase
helper as a sanitizer, so move the containment check inline at the spawn
cwd sink, matching the canonical barrier used elsewhere in the codebase.
Behavior is unchanged: the resolved stack directory must be contained in
the compose base and may not be the base itself.
* fix: hoist the compose-config spawn into the path-barrier scope
The earlier inline barrier sat in a different scope than the spawn cwd
sink (separated by the Promise-executor closure) and used a compound
guard, so CodeQL did not credit it. Use the exact canonical startsWith
barrier and hoist the spawn into the same scope as the check. Behavior
is unchanged: the executor runs synchronously in the same tick as the
spawn, so handlers still attach before any event can fire.
