How can I config offline database for trivy in Harbor 2.2.2 version

[cnskylee]

Q-I: As described in harbor.yml as follow, I modify skip_update from 'false' to 'enabled', and install harbor 2.2.2. When I use 'docker-compose start' harbor components，trivy-adapter status is always 'Restarting' and the others is 'health'.
Q-II: Another question is what should I do about configuration of offline database file for trivy as docs write as 'mount them in the /home/scanner/.cache/trivy/db path"? Though I have downloaded trivy-offline-db.tar.gz already. But I have no idea aount hwo to mount them in the /home/scanner/.cache/trivy/db path. Could you give more detail information, like the steps etc.?

You might want to enable this flag in test or CI/CD environments to avoid GitHub rate limiting issues.

If the flag is enabled you have to download the trivy-offline.tar.gz archive manually, extract trivy.db and

metadata.json files and mount them in the /home/scanner/.cache/trivy/db path.

skip_update: enabled
