[ammnt]

Hello,

please, help me to figure with this error:

2025/02/22 13:26:57 [INFO] ▶ Starting clair-scanner for image: ammnt/nginx:latest
2025/02/22 13:26:58 [INFO] ▶ Starting HTTP file server on 0.0.0.0:9279 serving path: /tmp/clair-scanner-2196524854

How to reproduce it:

docker run -p 127.0.0.1:5432:5432 -d --name db arminc/clair-db-v4
sleep 15
docker run -p 127.0.0.1:6060:6060 --link db:postgres -d --name clair arminc/clair-local-scan-v4
sleep 15
curl -L https://github.com/arminc/clair-scanner/releases/download/14.0.0/clair-scanner_linux-amd64 -o clair-scanner
chmod +x clair-scanner
DOCKER_GATEWAY=$(docker network inspect bridge --format "{{range .IPAM.Config}}{{.Gateway}}{{end}}")
./clair-scanner -c http://127.0.0.1:6060 --ip $DOCKER_GATEWAY --report='clair.report.json' ammnt/nginx:latest

And:

And looks like Clair is available for me from localhost:
