A non-interactive SSH exec (and sudo's secure_path) frequently has a
minimal PATH (~/usr/bin:/bin). Docker installed in /usr/local/bin
(get.docker.com), /snap/bin (snap) or /usr/sbin is then unreachable, so
every call died with "sh: docker: not found" and the page rendered as
"Docker nicht verfügbar" even though Docker was installed and running.
Prepend a comprehensive PATH to every docker invocation (available,
containers, containerAction, logs, composeStacks) so the binary is
located independent of the remote login shell. Reproduced the exact
failure and the fix through the real FleetService base64+sh transport.

Feedback on the new feature pages: buttons were oversized and Docker showed an empty list where
containers exist.
- Buttons: the new pages (groups, alerts×2, commands×2, certs, health) plus settings/login-protection
used size="lg" (h-11) on inline form-submit buttons, dwarfing the h-9 inputs and the surrounding
pills. Drop to the default `sm` (h-8) — matching every other form in the app (e.g. the e-mail save
button). The auth full-width CTAs keep size="lg" (their intended use); x-ring size="lg" is unrelated.
- Docker "empty" bug: DockerService::containers used `docker ps --format '{{json .}}'` (needs a modern
Docker AND depends on JSON key casing) and returned [] on ANY failure — so a daemon/permission/
rootless-socket error read as "no containers". Switched to a tab-separated `--format` (portable to
much older Docker, state derived from the Status text) and it now THROWS the real error on failure;
the page shows that reason instead of a misleading empty state (so the actual cause is visible).
- Patch rows: the pending/security/up-to-date pills now match the action button height (h-8) so the
row reads cleanly.
DockerServiceTest updated (tab-parse + state-from-status + throws-real-error). 742 tests green, Pint,
vite build clean.

Manage the containers running ON a fleet server, agentlessly — the integrated Portainer.
List containers + state, view logs, start/stop/restart, all via `docker` over SSH.
- DockerService (over FleetService::runPrivileged → base64 transport, shell-injection-safe):
containers() parses `docker ps -a --format '{{json .}}'`; containerAction() with an op allow-list
(start|stop|restart|pause|unpause); logs() with a clamped tail; composeStacks() read-only. Every
container ref is validated `^[a-zA-Z0-9][\w.-]*$` before interpolation — blocks shell metacharacters
AND a leading-dash argument injection (mirrors serviceAction). A missing/errored docker → [] (never
throws to the UI).
- Docker\Index page (route /docker, sidebar "Docker" with a new box icon): lazy container list for the
active server, open to any role. Container actions are `operate`-gated (abort_unless per method) and
audited (docker.action). Reading LOGS is also operate-gated (container output can leak secrets —
consistent with gating file CONTENT reads); the list/state stays open. ContainerLogs modal re-gates
the read itself.
- lang/{de,en}/docker.php + audit.php docker.action + shell.nav_docker (de/en parity). No emoji.
Codex hardening applied: logs output is byte-capped (head -c 262144) AND mb_scrub'd before it reaches
a Livewire property (invalid UTF-8 / a huge line can't break the JSON snapshot); the ref regex uses
\A…\z anchors so a trailing newline can't slip past.
16 new tests: service (json parse, empty-on-unavailable, valid-op command, reject unknown-op / shell-
metachars / leading-dash / trailing-newline ref, logs clamp+byte-cap, available probe), component
(viewer browses the list; viewer 403 on action AND on logs open + modal read; operator/admin act +
audited; logs modal tail). 685 tests green, Pint, lang parity, Codex-reviewed (fixes applied).
