Configuration to analyse docker-images with paclair for clair from nexus

Question

I am looking for an example-configuration for paclair so I can run paclair to analyse docker images which I stored in a private Docker registry which is hosted in nexus. At the moment I have the following configuration

General:
  clair_url: 'http://localhost:6060'
Plugins:
  Docker:
    class: paclair.plugins.docker_plugin.DockerPlugin
    registries:
      nexus.example.com:10009:
        verify: "/etc/ssl/certs/ca-bundle.crt"
        token_url: "https://nexus.example.com:10009/{image.repository}/v2/token?service=nexus.example.com:10009"
        api_prefix: "api/docker/{image.repository}"
        auth:
          - "jdoe"
          - "*****************"

and this works for Docker Images which are hosted on docker.io without any problems but if I try to run paclair with this configuration against a docker image from my private docker registry ie

paclair --debug Docker https://nexus.example.com:10009/myApp:1.0 push

it seems paclair skips the login against nexus.example.com and I don't see the reason with the following output:

Maybe someone here can give me a hint how I can configured paclair against a private nexus-docker-registry best regards Dan

Answer 1

Your problem should be solved with paclair's version 3.1.1 You are using a custom port on your registry and it was not supported by older versions. That's why the application is trying to reach docker.com instead of your custom registry.
