-Gitea compatible actions related to osv-scanner or the OSV ecosystem.
+Gitea-compatible composite actions around [Google OSV-Scanner](https://github.com/google/osv-scanner): cache the offline vulnerability database, merge SARIF reports, and extract container image references from manifests. Install the `osv-scanner` CLI from [upstream releases](https://github.com/google/osv-scanner/releases) (or your package manager) in your workflow.

+| `get-images-from-files`| Parse Dockerfiles, Kubernetes YAML, Compose, and Helmfile values for image refs (useful with `osv-scanner scan image …`). |
+
+## Workflows
+
+- **CI** (`.gitea/workflows/ci.yaml`): tests the actions above on `pull_request`.
+- **CD / Prerelease**: tag bump workflows unchanged (no scanner).

-# Setup DB Action
-
-A reusable Gitea Action that sets up the osv-scanner offline vulnerability database, restoring from cache if available.
-
-**Note:** This action only sets up the database. osv-scanner itself must be installed separately (e.g., using the `setup-osv` action). Subsequent steps receive `OSV_SCANNER_LOCAL_DB_CACHE_DIRECTORY` via the environment.

+# Setup OSV offline DB Action
+
+A reusable Gitea Action that restores or populates the [OSV-Scanner local vulnerability cache](https://google.github.io/osv-scanner/usage/offline-mode/) used with `--offline-vulnerabilities`.
+
+Databases are fetched with **curl** from `https://osv-vulnerabilities.storage.googleapis.com/` as described under [Manual database download](https://google.github.io/osv-scanner/usage/offline-mode/#manual-database-download): for each requested ecosystem, download `…/<ecosystem>/all.zip` into `osv-scanner/<ecosystem>/all.zip`. **OSV-Scanner is not invoked** for downloads.
+
+**Requires:** `curl`, `bash` 4+ (associative arrays), `python3` (URL-encoding paths).
+
+**Note:** This action only prepares the local DB directory. Install the scanner separately.
+
+## Ecosystems input
+
+Use **`ecosystems`**: a comma-separated list (spaces around commas are trimmed). Each token is matched to an entry from [ecosystems.txt](https://osv-vulnerabilities.storage.googleapis.com/ecosystems.txt) by:
+
+- **Slug match:** lowercased, spaces → `-`, brackets removed (e.g. `GitHub Actions` and `github-actions` both match).
+- **Special case:** `docker` is not an OSV ecosystem; it is treated as **`Linux`** (useful as a default when scanning image-related data). Override with `Alpine`, `Debian`, etc. if you prefer.
+
+The **`actions/cache` key includes** the sorted, slugified list of resolved ecosystems (e.g. `github-actions,go,linux,npm`) plus the hour bucket settings, so different ecosystem sets never share a cache entry.
+
+## Usage
+
+```yaml
+uses: https://gitea.example/your-user/osv-scanner-actions/setup-osv-db@0.0.1
+with:
+  ecosystems: PyPI,npm,Go
+```
+
+## Example workflow
+
+```yaml
+jobs:
+  scan:
+    runs-on: ubuntu-latest
+    steps:
+      - uses: actions/checkout@v4
+      - name: Setup offline DB
+        id: setup-db
+        uses: https://gitea.example/your-user/osv-scanner-actions/setup-osv-db@0.0.1
+        with:
+          cache-bucket-hours: 6
+          ecosystems: github-actions,npm,go,Alpine
+      - name: Scan (offline vulnerabilities only)
+        env:
+          OSV_SCANNER_LOCAL_DB_CACHE_DIRECTORY: ${{ steps.setup-db.outputs.cache-dir }}
+        run: osv-scanner scan source --offline-vulnerabilities -r .
+```

+## Inputs
+
+| Name                 | Description                                                               | Required | Default                          |
+| -------------------- | ------------------------------------------------------------------------- | -------- | -------------------------------- |
+| `cache-dir`          | Directory for `OSV_SCANNER_LOCAL_DB_CACHE_DIRECTORY`                      | No       | `${{ runner.temp }}/osv-scanner` |
+| `cache-bucket-hours` | `actions/cache` primary key includes `floor(UTC unix time / (3600 × N))`. | No       | `24`                             |
+| `ecosystems`         | Comma-separated tokens (names/slugs; `docker` → `Linux`).                 | No       | `github-actions,npm,go,docker`   |
+
+## Outputs
+
+| Name        | Description        |
+| ----------- | ------------------ |
+| `cache-dir` | Same as input path |
+
+## Behavior
+
+- **Cache:** Key pattern `osv-scanner-db-{hours}h-eco-{sorted-slugs}-{bucket}`. `restore-keys` reuse the newest cache for the same hours + ecosystem set when the current time bucket misses.
+- **Populate:** On cache miss, `${cache-dir}/osv-scanner` is recreated and only the requested ecosystems are downloaded.

-# Setup OSV Scanner Action
-
-A reusable Gitea Action that downloads and sets up the osv-scanner binary for vulnerability scanning.
-
-The downloaded binary is verified against a pinned SHA-256 digest for the runner architecture.
-
-## Usage
-
-### Basic Usage
-
-```yaml
-- name: Setup OSV Scanner
-  uses: your-username/osv-scanner-actions@main/setup-osv
-  with:
-    version: "v2.4.0"
-    amd64-digest: "15314940c10d26af9c6649f150b8a47c1262e8fc7e17b1d1029b0e479e8ed8a0"
-    arm64-digest: "44e580752910f0ff36ec99aff59af20f65df1e859aa31e5605a8f0d055b496e9"
-```
-
-Digests are published in each release's `osv-scanner_SHA256SUMS` file (e.g. for `osv-scanner_linux_amd64` / `osv-scanner_linux_arm64`). You may pass either bare hex or `sha256:<hex>`.
-
-### Complete Example
-
-```yaml
-name: Security Scan

-
-jobs:

-    runs-on:
