Paclair

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!

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.
General::cve_whitelist	CVE vulnerability list not to be included in the report post analysis (stats or html).
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.

Examples

Push ubuntu image to Clair

$ paclair --conf conf/conf.yml Docker ubuntu push
Pushed ubuntu to Clair.

Analyse ubuntu image (stats only show fixable CVE)

$ paclair --conf conf/conf.yml Docker ubuntu analyse --output-format stats
Medium: 3

You can have the full json if you don't specify --output-format stats.

Analyse ubuntu image and get a html report in directory /tmp

$ paclair --conf conf/conf.yml Docker ubuntu analyse --output-format html --output-dir /tmp

Delete ubuntu image

$ paclair --conf conf/conf.yml Docker ubuntu delete
ubuntu was deleted from Clair.
