# Harbor Scanner Adapter for Trivy
The Harbor [Scanner Adapter][harbor-pluggable-scanners] for [Trivy] is a service that translates the [Harbor] scanning
API into Trivy commands and allows Harbor to use Trivy for providing vulnerability reports on images stored in Harbor
registry as part of its vulnerability scan feature.
Harbor Scanner Adapter for Trivy is the default static vulnerability scanner in Harbor >= 2.2.
For compliance with core components Harbor builds the adapter service binaries into Docker images based on Photos OS
(`goharbor/trivy-adapter-photon`), whereas in this repository we build Docker images based on Alpine
(`aquasec/harbor-scanner-trivy`). There is no difference in functionality though.

## Deployment
### Harbor >= 2.0 on Kubernetes
In Harbor >= 2.0 Trivy can be configured as the default vulnerability scanner, therefore you can install it with the
official [Harbor Helm chart], where `HARBOR_CHART_VERSION` >= 1.4:
```
helm repo add harbor https://helm.goharbor.io
```
```
helm install harbor harbor/harbor \
--create-namespace \
--namespace harbor
```
The adapter service is automatically registered under the **Interrogation Service** in the Harbor interface and
designated as the default scanner.
### Harbor 1.10 on Kubernetes
1. Install the `harbor-scanner-trivy` chart:
```
helm repo add aqua https://aquasecurity.github.io/helm-charts
```
```
helm install harbor-scanner-trivy aqua/harbor-scanner-trivy \
--namespace harbor --create-namespace
```
2. Configure the scanner adapter in the Harbor interface.
1. Navigate to **Interrogation Services** and click **+ NEW SCANNER**.
2. Enter as the **Endpoint** URL and click **TEST CONNECTION**.
3. If everything is fine click **ADD** to save the configuration.
3. Select the **Trivy** scanner and set it as default by clicking **SET AS DEFAULT**.
Make sure the **Default** label is displayed next to the **Trivy** scanner's name.
## Configuration
Configuration of the adapter is done via environment variables at startup.

## Troubleshooting
### Error: database error: --skip-db-update cannot be specified on the first run
If you set the value of the `SCANNER_TRIVY_SKIP_UPDATE` to `true`, make sure that you download the [Trivy DB]
and mount it in the `/home/scanner/.cache/trivy/db/trivy.db` path.
### Error: failed to list releases: Get : dial tcp: lookup api.github.com on 127.0.0.11:53: read udp 127.0.0.1:39070->127.0.0.11:53: i/o timeout
Most likely it's a Docker DNS server or network firewall configuration issue. Trivy requires internet connection to
periodically download vulnerability database from GitHub to show up-to-date risks.
Try adding a DNS server to `docker-compose.yml` created by Harbor installer.
```yaml
version: 2
services:
trivy-adapter:
# NOTE Adjust IPs to your environment.
dns:
- 8.8.8.8
- 192.168.1.1
```
Alternatively, configure Docker daemon to use the same DNS server as host operating system. See [DNS services][docker-dns]
section in the Docker container networking documentation for more details.
### Error: failed to list releases: GET : 403 API rate limit exceeded
Trivy DB downloads from GitHub are subject to [rate limiting][gh-rate-limit]. Make sure that the Trivy DB is mounted
and cached in the `/home/scanner/.cache/trivy/db/trivy.db` path. If, for any reason, it's not enough you can set the
value of the `SCANNER_TRIVY_GITHUB_TOKEN` environment variable (authenticated requests get a higher rate limit).
