Cache Directory

Specify where the cache is stored with --cache-dir.

$ trivy --cache-dir /tmp/trivy/ image python:3.4-alpine3.9

Cache Backend

!!! warning "EXPERIMENTAL" This feature might change without preserving backwards compatibility.

Trivy supports local filesystem and Redis as the cache backend. This option is useful especially for client/server mode.

Two options:

• fs
  • the cache path can be specified by --cache-dir
• redis://
  • redis://[HOST]:[PORT]

$ trivy server --cache-backend redis://localhost:6379
