# Docker label discovery
During onboarding, Homarr scans running containers on every reachable
[Docker-compatible host](/docs/integrations/docker). Labels let you provide exact app metadata instead of relying on
image-name matching. You can review and deselect every result before Homarr creates anything.
A container with valid Homarr labels takes priority over image-based discovery. Containers without valid labels can
still be suggested from their image and published ports.
## Homarr labels
`homarr.name` and `homarr.href` are required for label discovery. All other labels are optional.
| Label | Purpose |
| -------------------- | -------------------------------------------------------------------------- |
| `homarr.name` | App or integration display name |
| `homarr.href` | Address opened by the app and used as the suggested integration address |
| `homarr.group` | Container section that receives the selected app and compatible widget |
| `homarr.icon` | App icon URL |
| `homarr.description` | App description |
| `homarr.ping` | Address used for app status checks |
| `homarr.id` | Stable source identifier; defaults to the Docker container ID |
| `homarr.board` | Intended board name; see [Board targeting](#board-targeting) |
| `homarr.integration` | Homarr integration kind, for example `sonarr` |
| `homarr.widget` | Homarr widget kind to add when it supports the selected integration |
| `homarr.hide` | Excludes the container when this label is present, regardless of its value |
Unknown integration and widget kinds are ignored. Do not put API keys, passwords, or other secrets in labels. Enter
credentials in onboarding, where Homarr stores them using its normal encrypted integration-secret flow.
## Compose example
```yaml
services:
sonarr:
image: lscr.io/linuxserver/sonarr:latest
labels:
homarr.name: "Sonarr"
homarr.href: "http://server.local:8989"
homarr.group: "Media"
homarr.icon: "https://cdn.jsdelivr.net/gh/homarr-labs/dashboard-icons/svg/sonarr.svg"
homarr.description: "TV library"
homarr.ping: "http://server.local:8989"
homarr.integration: "sonarr"
homarr.widget: "calendar"
```
Use an address that is reachable where it is needed. A Docker service name can work for server-side integration
requests, while an app link opened in a browser usually needs a LAN hostname, IP address, or reverse-proxy address.
## Homepage label fallback
When `homarr.name` is absent, onboarding also understands these Homepage labels:
- `homepage.name`
- `homepage.href`
- `homepage.group`
- `homepage.icon`
- `homepage.description`
`homepage.name` and `homepage.href` are required for the fallback. Homarr does not combine partial Homarr metadata with
Homepage metadata: once `homarr.name` is present, use `homarr.*` labels for the remaining fields too.
## What onboarding creates
In **Connect**, label-discovered apps and integrations appear before image-based suggestions. You can import multiple
services in one pass and edit every suggested address. For image-matched apps, Homarr shows the detected service type
and uses it when building host, subdomain, or reverse-proxy path suggestions.
When setup completes, Homarr rechecks the selected container sources and then:
- creates an app with its name, address, icon, description, and ping address;
- creates the requested integration and links its app after you provide required credentials;
- places grouped apps in a board container named by `homarr.group`;
- places ungrouped apps in the main board area;
- adds `homarr.widget` only when the widget kind is valid and compatible with the selected integration;
- keeps image-based discovery available for unlabeled containers.
If a selected container disappears, targets another board, or requests an incompatible widget, setup finishes with a
warning instead of creating an invalid board item.
## Board targeting
On a fresh installation with one seeded `dashboard` board, one unique selected `homarr.board` value can name that first
board. Otherwise, the label must match the board selected in onboarding. Services labeled for another board are skipped
and reported in the completion warning.
Onboarding configures one board at a time. Run normal board management after setup if you want to distribute services
across several boards.
