## Docker runtime
|
|
|
|
| Setting | Observed value |
|
|
| --- | --- |
|
|
| Engine / API | Docker CE `29.8.2` / `1.56` |
|
|
| Compose CLI plugin | `v5.6.0`; not proof of Portainer's Compose implementation |
|
|
| containerd / runc | `v2.3.6` / `1.5.1` |
|
|
| Storage | `overlayfs`; containerd snapshotter |
|
|
| Cgroups | `systemd`; v2 |
|
|
| Logging | `json-file`; default |
|
|
| Firewall backend | `iptables` |
|
|
| Runtime security | AppArmor, seccomp, cgroup namespaces |
|
|
| Swarm / live restore | Inactive / disabled |
|
|
|
|
Docker/containerd services and `docker.socket` are enabled.
|
|
Docker starts `/usr/bin/dockerd -H fd:// --containerd=/run/containerd/containerd.sock`.
|
|
Supplied Docker unit has no explicit `/data` mount dependency or ordering against
|
|
`rclone-seedbox.service`.
|
|
|
|
## Host administration
|
|
|
|
| Account / group | Identity |
|
|
| --- | --- |
|
|
| `jay` | UID/GID `1000:1000`; `/home/jay`; bash; member of `sudo`, `docker`, `video`, `backups` |
|
|
| `backup-puller` | UID/GID `1001:1001`; `/home/backup-puller`; bash; member of `backups`; origin/purpose not recognized by owner |
|
|
| `backups` | Shared group; GID `1002` |
|
|
|
|
WireGuard and rclone: apt-managed. `wg-quick@wg0.service` is active in the supplied
|
|
snapshot. No host-level nginx on Jupiter; nginx still exists in application
|
|
containers. `unattended-upgrades.service` is enabled; effective update policy
|
|
not supplied.
|
|
|
|
No independent host-configuration archive is maintained. `backup-puller` must
|
|
not be assumed to perform backups; identify SSH/cron/service dependencies before
|
|
removing or repurposing it.
|
|
|
|
Hardware/versions are a dated snapshot, not live telemetry.
