Push and Analyse containers with Clair

Project description

Paclair is a Python3 Cli tool to interact with Coreos’s Clair.

Features:

  • Now compatible with Clair V3 (delete is not available)
  • No need to have docker installed since Paclair interacts directly with the registries.
  • Compatible with all registries.
  • Simple to use.
  • Easy integration in a CI job thanks to a lightweight output mode.

Installation

To install Paclair, simply use pip (or pipenv):

$ pip install paclair
✨🍰✨

Voilà!

Configuration

Example

An example configuration file is available in the conf directory

General:
  clair_url: 'https://localhost:6060'
  verify: "/etc/ssl/certs/my_custom_ca.crt"
Plugins:
  Docker:
    class: paclair.plugins.docker_plugin.DockerPlugin
    registries:
      registry.gitlab.domain.com:
        auth:
          - "*****"
          - "*****"
        verify: "/etc/ssl/certs/ca-certificates.crt"

Plugins are dynamically loaded during execution. That’s why you have to specify the class of the plugins you want to use.

We have various plugins to interact with different sources (ex: docker registry, Elasticsearch) because we use a custom variant of Clair which can analyse more than Docker images.

If you want to use Paclair only to analyse docker images, don’t bother with others plugins.

Options

Config Option Description
General::clair_url url of the Clair Server.
General::verify Either a boolean, in which case it controls whether we verify the server’s TLS certificate, or a string, in which case it must be a path to a CA bundle to use.
General::clair_api_version Clair Api Version. If different from 3, will be set to default. Default to 1.
General::html_template Html template. You can use a custom html template when using html output.
Plugins List of plugins to use. If you only want to analyse docker images, keep the default configuration.
Plugins::Docker::class Class for the docker plugin
Plugins::Docker::registries You can specify configuration for registries (authentification, …) if needed.
Plugins::Docker::registries::regi stry1::auth login/password
Plugins::Docker::registries::regi stry1::verify Either a boolean, in which case it controls whether we verify the server’s TLS certificate, or a string, in which case it must be a path to a CA bundle to use.
Plugins::Docker::registries::regi stry1::protocol Protocol to use (http or https). Default to https.
Plugins::Docker::registries::token You can specify an authentication token (use with token_type). Default to None.
Plugins::Docker::registries::token _type Specify the token type. Default to Bearer.

Running the tests
