[0xDagal]

Version of copa

v0.6.1-81-g2335453

Expected Behavior

Patching nginx:1.21.6 with a proxy should work.

Actual Behavior

The patch does not work:

Running in debug, I saw:

Steps To Reproduce

Run trivy on nginx:1.21.6 and name the report nginx.1.21.6.json then run a moby/buildkitd container and finally run copa patch -i nginx:1.21.6 -r nginx.1.21.6.json --addr docker-container://copa-buildkitd-1.

@0xDagal would you be able to share your setup steps for your buildkit container?

[0xDagal]

Yes, I run it in a docker-compose like so:

services:
  buildkitd:
    image: moby/buildkit:latest
    privileged: true
    entrypoint: buildkitd
    volumes:
      - ./buildkitd.toml:/etc/buildkit/buildkitd.toml

in my buildkitd.toml, there are only registry mirrors like for example:

[registry."quay.io"]
  mirrors = ["my-quay-mirror.lan"]
