Cache Directory

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

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

Cache Backend

[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]

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