usr/bin/k6 (gobinary)

k6 version

k6:master

OS

linux/amd64

Docker version and image (if applicable)

loadimpact/k6:master

Steps to reproduce the problem

Build docker image
Run trivy Security Scan

Expected behaviour

Security scan should pass

Actual behaviour

Security scan is failing

[na--]

Thanks for this report. We don't use or expose awk in the image, so these security issues don't affect us. Besides, since we don't fix the minor version of Alpine in the Dockerfile:

k6/Dockerfile

Line 7 in 804203b

FROM alpine:3.14

The latest master docker image already uses v3.14.3, which includes fixes for them:

$ docker run -it --rm --entrypoint cat loadimpact/k6:master "/etc/alpine-release"
3.14.3

All of that said, there isn't a reason to not update to Alpine 3.15, so I'll leave this issue open and just change the title to that.
