title: Resources Hub
description: Browse, filter, scan, and clean up Docker images, volumes, networks, and unmanaged containers from a single view.
---

The **Resources** tab shows everything Docker is storing on your host, broken down by ownership, with one-click cleanup, on-demand vulnerability scanning, and a topology view of how your containers connect.

</Frame>

## Reclaim hero

When there is reclaimable disk space (unused images, stopped containers, or dangling volumes), an amber banner leads the view with the total amount you can free and a `·`-separated breakdown of what contributes to it (for example, `16 unused images · 10 dangling volumes`). Click **Review & prune** to open a single confirmation dialog scoped to every reclaimable resource at once.

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

<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 shows how your Docker disk usage is distributed:

| Segment | Meaning |
|---------|---------|
| **Sencho managed** (green) | Images and volumes 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 safe to delete |

Each segment shows its size and its share of the total footprint. Tile area is proportional to bytes. Click any segment 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** | Images with no running containers in 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) |

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 operation, with a summary of what will be removed. 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>

## Resource tabs

Below the hero, four tabs partition your inventory: **images**, **volumes**, **networks**, and **Unmanaged**. The Unmanaged tab shows a count badge whenever orphan containers are detected.

A **Scan history** button sits on the right of the tab strip when image vulnerability scanning is configured for the node. It opens the full scan record so you can review past results without launching a new scan. See [Vulnerability scanning](/features/vulnerability-scanning) for the full workflow.

### Images

Lists all Docker images on the host with their ID, repository tag, size, and status.

**Filter chips:** `All`, `Managed`, `External`. Each chip shows the matching count, for example `All 31 · Managed 14 · External 17`.

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

- A usage badge: `In Use` plus the stack name when the image runs in a Sencho-managed stack, `In Use` plus `External` when it runs in another Docker project, or `Unused` when no container references it.
- A severity badge from any image scan: `Clean`, `LOW`, `MEDIUM`, `HIGH`, `CRITICAL`, or `UNKNOWN`. 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)`. The full scan is a paid-tier option.
- **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 three sections:

- **Overview** lists the ID, 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.

The inspect sheet is read-only and available to all roles.

### Volumes

<Frame>
  <img src="/images/resources/resources-volumes-tab.png" alt="Volumes tab with Largest 5 and Recently changed landing cards above the volume list" />
</Frame>

Lists all Docker volumes with name, driver, mount point, and managed status.

A two-card landing strip sits above the table:

- **Largest 5** ranks volumes by on-disk size, with the total volume count alongside.
- **Recently changed** highlights volumes created or touched in the last 24 hours, with relative timestamps such as `24m ago`.

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

<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.

- **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>

### Networks

<Frame>
  <img src="/images/networks/networks-list.png" alt="Networks tab in List view with filter chips, view-mode toggle, Create Network button, and the network table" />
</Frame>

Lists all Docker networks with ID, name, driver, scope (`local`, `global`, `swarm`), and managed status. System networks (`bridge`, `host`, `none`) are shown but cannot be deleted.

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

A **List | Topology** view-mode toggle sits on the right of the toolbar. **List** is the default tabular view; **Topology** is a graph view of how containers connect to networks (covered below).

#### Create Network

In **List** view, the **+ Create Network** button (admin-only) opens the creation dialog.

<Frame>
  <img src="/images/networks/create-network.png" alt="Create network dialog with Name, Driver, Subnet, Gateway fields, and Internal and Attachable toggles" />
</Frame>

| Field | Required | Description |
|-------|----------|-------------|
| **Name** | Yes | Alphanumeric, hyphens, underscores, and dots |
| **Driver** | No | `bridge` (default), `overlay`, `macvlan`, `host`, or `none` |
| **Subnet** | No | CIDR notation, for example `172.20.0.0/16` |
| **Gateway** | No | Gateway IP, for example `172.20.0.1` |
| **Internal** | No | Isolates the network from external access |
| **Attachable** | No | Allows containers to be manually attached |

The footer shows a **DRIVER** chip that mirrors the selected driver, and a **Create network** button that stays disabled until the form is valid.

#### Inspect network

Click the eye icon on any network row to open a detail sheet.

<Frame>
  <img src="/images/networks/network-inspect.png" alt="Network inspect sheet for arr-net showing the Overview, IPAM configuration, and Connected containers sections" />
</Frame>

The sheet is grouped into sections:

- **Overview** lists the ID, driver, scope, creation date, and the internal/attachable flags.
- **IPAM configuration** shows the subnet, gateway, and IP range for each configured address pool.
- **Options** lists driver-specific options applied to the network (rendered only when present).
- **Connected** shows every container attached to the network, with its name, IPv4 address, and MAC address. The section header counts the containers.
- **Labels** lists all Docker labels on the network (rendered only when present).

#### Network topology

Switch to the **Topology** view to see an interactive graph of your Docker networks and the containers attached to them. The graph uses an automatic hierarchical layout (networks on top, containers below) that scales cleanly regardless of how many networks and containers you have.

<Frame>
  <img src="/images/networks/network-topology.png" alt="Network topology graph with arr-net at top and the connected containers fanned out below it, mini-map and zoom controls visible" />
</Frame>

- **Network nodes** are dashed-border cards showing the network name and driver, color-coded by status (managed, external, system).
- **Container nodes** are cards showing the container name, a state indicator, the stack badge, the image name, and the IPv4 address per network.
- **Edges** are animated, color-coded connections between networks and their containers.
- **Click-to-logs.** Click any running container node to open its log viewer directly.
- **Refresh.** Use the refresh button in the toolbar to re-fetch the topology on demand.
- Pan, zoom, and drag nodes to explore the graph.
- A **mini-map** in the bottom-right gives an overview of the full graph. Zoom and fit-view controls sit on the bottom-left.

##### Show system networks

By default, system networks (`bridge`, `host`, `none`) are hidden so the graph stays focused on user networks. Toggle **Show system networks** to include them, which is useful for debugging containers attached to the default bridge.

<Frame>
  <img src="/images/networks/network-topology-toggle.png" alt="Topology with Show system networks toggled on; arr-net plus the bridge, none, and host system networks all visible at the top" />
</Frame>

### Unmanaged

<Frame>
  <img src="/images/resources/resources-unmanaged-tab.png" alt="Unmanaged tab with Select all checkbox, Purge Selected action, and a container row grouped under External Project: sencho" />
</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.

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."
