Tern Docker image: Pulling images from private registry #1160

Closed software-testing-professional closed 2 years ago

software-testing-professional commented 2 years ago

Is it possible to pull and analyze images from a private registry (like Artifactory)?

This happens when the Tern container is used in Gitlab CI. Although a docker login ... has been executed, and the /.docker/config has been mounted into the Tern container.

It works fine on my local machine.

It results in 2022-04-21 09:04:17,531 - WARNING - docker_api - Build failed: Get https://***********.com/v2/its-javabase/manifests/java-11: unknown: Authentication is required

I'm running Tern like this:

docker run \
  --privileged \
  -v /var/run/docker.sock:/var/run/docker.sock \
  -v "$PWD/tmp/${PROJECT_NAME}:/project" \
  -v "$PWD/docker/config.json:/root/.docker/config.json" \
  -v "$PWD/docker/config.json:/root/.docker/config" \
  **************.com/ternd \
  --driver fuse \
  report \
    -d /project/Dockerfile \
    -f cyclonedxjson \
    -o /project/container.bom.json

Thanks for your help!

Hello! The issue of private repositories can be solved by either changing the Dockerfile or to mount the registries file to the build tern image. However, this doesn't work for situations where you want to run a demo registry without https or TLS verification. For this purpose, you would need to send the tls-verify=false flag to skopeo to pull the image.

See https://github.com/tern-tools/tern/issues/1087#issuecomment-1006656236 for more info about how to add your private registry to the base tern image. Here's another suggestion from a similar question: https://github.com/tern-tools/tern/issues/1121#issuecomment-1044907385.

Hi @rnjudge,

yes it works now.

It turned out that the config.json was incomplete. I added some more authentication data to the .docker/config.json. Now it is possible to pull Artifactory images via skopeo.

Thanks for your help!

Best regards, Michael
