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).
