## Reclaim hero

Once enabled for a node, an amber banner leads the view whenever there is reclaimable disk space (unused images, stopped containers, or dangling volumes), showing the total amount you can free and a `·`-separated breakdown of what contributes to it (for example, `2 unused images · 10 dangling volumes`). Click **Review & prune** to open a confirmation dialog that lists the exact items that will be removed (capped in the preview with an "and N more" note when the list is long). Confirm only after the plan is ready; Sencho rechecks the list at execute time and skips anything that is no longer eligible.

The hero stays hidden when there is nothing to reclaim, keeping the view focused on the rest of your inventory.

The total does not include images Sencho holds as rollback protection points: a prune plan never removes those images. They surface in the Rollback tab and are freed once the hold is released or superseded.

To set the banner aside without pruning, use the **×** in its top-right corner. It stays hidden on that browser until the reclaimable total grows past the amount it held when you dismissed it, so a small, stubborn remainder will not keep reappearing while a genuine new build-up still surfaces.

The banner is off by default and applies per node. To turn it on, open **Settings → Monitoring → Docker & Storage** and switch on **Show reclaimable-space banner**.

<Note>
  The banner and the **Review & prune** action are admin-only. Read-only roles still see the rest of the page but cannot trigger destructive operations.
</Note>

## Docker Disk Footprint

The left card under the hero breaks down your Docker disk usage into three tiles:

| Tile | Meaning |
|------|---------|
| **Sencho managed** (green) | Images and volumes **currently used** by stacks in your `COMPOSE_DIR` |
| **External** (amber) | Images and volumes used by Docker projects outside Sencho |
| **Reclaimable** (neutral) | Unused images, stopped containers, and dangling volumes Docker can free. Images Sencho holds as rollback protection points are not included; they surface in the Rollback tab and are freed once the hold is released or superseded |

The managed tile does not count free (unused) images. Those rows appear under reclaimable space and in the Images tab as unused until you prune them.

Each tile shows its size and its share of the total footprint as a percentage. The layout itself is fixed (Sencho managed on the left, External and Reclaimable stacked on the right); tile size does not scale with the percentage, so read the numbers rather than the proportions. Click any tile to filter the resource tabs below to that category.

## Quick Clean

The right card under the hero exposes four prune actions. Each tile has a single primary button that targets **Sencho-managed resources only**, so by default the action will not touch external Docker projects.

| Action | What it removes |
|--------|----------------|
| **Prune Unused Images** | Free images owned by or still matching repositories used by your Sencho stacks |
| **Prune Unused Volumes** | Volumes not attached to any Sencho container |
| **Prune Dead Networks** | Networks not connected to any Sencho container |
| **Purge Unmanaged Containers** | Containers Sencho doesn't recognize (started outside it) |

Managed image prune is broader than the green **Sencho managed** tile: after a stack update leaves an older tag unused, that free image can appear in the managed prune plan when a running stack container still uses the same image repository. Images labeled for Compose projects Sencho does not manage stay out of managed prune (use **All Docker** for a full host reclaim). Untagged dangling layers have no repository to match and usually require **All Docker** / all-scope prune.

The first three tiles also show a **More options** menu with a single destructive entry, **All Docker (includes external)**, that broadens the prune to every Docker resource on the host. Use it carefully, since it can affect other Compose projects sharing the same daemon. The **Purge Unmanaged Containers** tile has no menu and always targets unmanaged containers only.

A confirmation dialog appears before any destructive prune. Sencho first builds an itemized plan of exactly which resources will be removed, shows that list in the dialog, and only then enables confirm. The confirm action is bound to that plan: if the daemon state changes before you confirm, Sencho refreshes the plan instead of deleting a different set. While the operation runs, a loading notification keeps you informed; on completion it is replaced with a success or error notification, including how much space was reclaimed.

<Note>
  Quick Clean is admin-only. The panel is hidden for users without admin permissions.
</Note>

<Note>
  Every prune action on this page runs through the Docker API. When Sencho runs behind a Docker socket proxy, pruning requires POST plus the IMAGES, VOLUMES, NETWORKS, and CONTAINERS groups for the resources being cleaned. See [Self-Hosting: Docker socket proxy](/operations/self-hosting#docker-socket-proxy).
</Note>

## Resource tabs

Below the hero, three tabs partition your inventory: **Images**, **Volumes**, and **Unmanaged**. The Unmanaged tab shows a count badge whenever orphan containers are detected.

Network inventory, topology, inspect, and findings live on the dedicated [Networking](/features/networking) page. **Quick Clean** still includes **Prune Dead Networks**.

Each of the first three tabs shares the same toolbar pattern: a collapsible search (click the magnifying glass to open a text filter, matching by name or repository tag) and an **All / Managed / External** filter with a live count on each chip. Sortable columns toggle ascending/descending order when clicked.

A **Scan history** button sits on the right of the Images tab's toolbar when image vulnerability scanning is configured for the node. It takes you to the [Security page](/features/security) History tab so you can review past results without launching a new scan. See [Vulnerability scanning](/features/vulnerability-scanning) for the full workflow.

<Note>
  Sencho protects its own image, network, and named volumes from accidental deletion. The matching rows carry a **Sencho** pill alongside the managed status and the delete control is disabled.
</Note>

### Images

Lists all Docker images on the host with their ID, repository tag, size, and status. Click **Repository:Tag**, **Size**, or **Status** to sort.

**Filter chips:** `All`, `Managed`, `External`. Each chip shows the matching count, for example `All 18 · Managed 15 · External 3`.

**Status column** combines two pieces of information per row:

- A usage badge: `In Use` plus one chip per Sencho stack that uses the image (click a chip to open that stack), `In Use` plus `External` when it runs only in another Docker project, or `Unused` when no container references it.
- A severity badge from any image scan: `Clean` (no findings at all), a CVE severity (`LOW`, `MEDIUM`, `HIGH`, `CRITICAL`, or `UNKNOWN`), or `Findings` (no CVEs, but a secret or misconfiguration finding). Click the badge to open the scan results.

**Per-row actions** sit on the right:

- **Inspect** (eye) opens the image detail sheet.
- **Scan** (shield) opens a menu with `Scan (vulnerabilities)` and `Full scan (vulnerabilities + secrets)`. Full scan is available on every tier.
- **Delete** (trash, admin-only) removes the image. Sencho warns before deleting an image that is still in use.

#### Inspect image

Click the eye icon on any image row to open a detail sheet with these sections. The same sheet is also available from each container card on the stack detail view (**Inspect image**, between View logs and Monitor). From that entry point, Used by lists the current stack only.

<Frame>
  <img src="/images/resources/resources-image-inspect.png" alt="Image inspect sheet showing the Used by, Overview, Config, and Layers sections for a running image" />
</Frame>

- **Used by** (from Resources) lists every Sencho stack that references the image; chips open that stack. Sourced from the Resources inventory, so it stays visible while inspect loads or if inspect fails. From a stack container card, Used by shows the current stack only, as a non-clickable badge.
- **Overview** lists the ID (with a copy button), size, creation date, architecture and OS, author, and all repository tags.
- **Config** shows the default `Cmd`, `Entrypoint`, `WorkingDir`, `User`, exposed ports, environment variables, and labels. Env vars and labels are collapsible.
- **Layers** lists the layer history in build order. Each row shows the layer index, size, age, and the build command (`CreatedBy`). Empty layers (metadata-only, zero bytes) are dimmed.
- **Registry tags** (admins) lists remote tag names from a matching configured registry, with a **Load more** button when the registry has additional pages. See [Private registries](/features/private-registries#browse-tags-from-resources) for credential and failure behavior. Vulnerability history and caching use the image digest when available; see [Tags vs digests](/features/vulnerability-scanning#tags-vs-digests).

The inspect sheet is available to all roles. Registry tag browsing is admin-only.

### Volumes

<Frame>
  <img src="/images/resources/resources-volumes-tab.png" alt="Volumes tab with the search and filter toolbar above the volume list" />
</Frame>

Lists all Docker volumes with name, driver, mount point, and managed status. Click **Name** or **Driver** to sort.

**Filter chips:** `All`, `Managed`, `External`, each with its count.

Anonymous volumes (Docker-generated 64-character hash names, typical of a container that declares a volume without naming it) show a shortened label with an **anonymous** chip so the table stays readable; hover the name for the full hash.

<Warning>
  Deleting a volume is permanent. Any data stored in it will be lost. Always back up important volume data before pruning.
</Warning>

#### Browse volume contents

Click the folder icon on any volume row (admin-only) to open a read-only browser for that volume. The panel shows a directory tree on the left and a file viewer on the right. For an anonymous volume, a band above the tree shows the full 64-character name with a copy button, since the sheet's title and breadcrumb only show the shortened form.

- **Read only.** No edits, no writes, no deletions. The browser launches a short-lived helper container with the volume mounted read-only.
- **Size cap.** Files are read up to 5 MB. Larger files show a truncation banner.
- **Binary files** are displayed as a hex view. Plain text is shown directly.
- **Symlinks** are listed but never followed. Reading a symlink path returns an error.
- **Audit log.** Every file read is recorded in the audit log, including failed reads, with the volume and path. Use this for compliance and incident review.

<Warning>
  Volumes commonly contain database files, password hashes, certificates, and other secrets. Treat the volume browser as a high-power admin tool.
</Warning>

### Unmanaged

<Frame>
  <img src="/images/resources/resources-unmanaged-tab.png" alt="Unmanaged tab showing the No unmanaged containers success state" />
</Frame>

Lists containers running on the host that are not part of any Sencho-managed stack: containers started with `docker run`, or Compose projects outside your `COMPOSE_DIR`. The tab shows a count badge when any are detected. The running Sencho container itself is excluded from this list so it cannot be purged by accident.

Containers are grouped by their external Compose project. Each group has an **External Project** header with the project name and a container count. Each container row shows:

- A row checkbox for multi-selection.
- The container name (or short ID if unnamed).
- A state pill, for example `running`.
- The image reference, in monospace below the name.

The toolbar above the list provides a **Select all** checkbox and a destructive **Purge Selected (N)** button. The button stays disabled until at least one row is checked, and is admin-only.

When no unmanaged containers are detected, the tab shows a success state with the message "No unmanaged containers" and the subline "All running containers are managed by Sencho."

## Troubleshooting

<AccordionGroup>
  <Accordion title="The delete button is greyed out on an image, network, or volume row">
    The row carries a **Sencho** pill, which means the resource is the running Sencho instance's own image, attached network, or named volume. Sencho refuses to delete the resources that keep itself running so an admin cannot take the dashboard offline by accident. Bind-mounted host paths are not shown in the Volumes tab and are not affected.
  </Accordion>
  <Accordion title="I expected to see the Sencho container in the Unmanaged tab and it is not there">
    The Unmanaged tab filters the running Sencho container out by design so it cannot be selected and purged. Other containers started outside Sencho (with `docker run` or by a Compose project outside `COMPOSE_DIR`) still appear normally. To inspect the Sencho container itself, use **Host Console** or `docker ps` on the host.
  </Accordion>
  <Accordion title="The reclaim banner will not go away, or shows a small amount that will not prune">
    The banner starts from what Docker reports as reclaimable on the node, subtracts images Sencho holds as rollback protection points, and counts only the resources a standard prune can actually remove. Held images are never part of that total and never appear in a prune plan, so the residue after a prune is normally the storage driver still reporting a few megabytes that the prune did not free. Held images are listed in the **Rollback** tab and are freed once the hold is released or superseded. To stop the banner drawing attention to a stubborn remainder, dismiss it with the **×** in its top-right corner; it stays hidden until the reclaimable total grows past that point. To turn it off for the node entirely, switch off **Show reclaimable-space banner** in **Settings → Monitoring → Docker & Storage**.
  </Accordion>
  <Accordion title="A prune plan lists several tags for one image">
    Unused images often carry more than one name, such as a version tag and `latest`. Sencho includes every reviewed tag in the prune confirmation. Confirming removes those tags one by one, and Docker deletes the image once no names remain.

    <Frame>
      <img src="/images/resources/resources-prune-confirm.png" alt="Prune confirmation dialog listing an unused image with both a version tag and latest in the reviewed items" />
