Dockerfile.n8n (1)

13-13: Pin ffmpeg to a specific version for reproducible builds.

git is pinned to 2.49.1-r0, but ffmpeg is unpinned. This inconsistency means the image isn't fully reproducible — a rebuild could pull a different ffmpeg version with breaking changes or vulnerabilities.

Proposed fix

First, find the current version available in the base image's Alpine release:

#!/bin/bash
# Check which Alpine version the base image uses and the available ffmpeg package version
docker run --rm n8nio/n8n:1.109.2 sh -c "cat /etc/alpine-release && apk info ffmpeg 2>/dev/null || apk list ffmpeg 2>/dev/null || apk search -e ffmpeg"

Then pin accordingly, e.g.:

-  apk add --no-cache git=2.49.1-r0 ffmpeg && \
+  apk add --no-cache git=2.49.1-r0 ffmpeg=<version> && \
