ConPan: Analyze your Docker container in peace

ConPan inspect Docker containers and extract their installed packages to analyze them.

ConPan analyzes packages technical lag, vulnerabilities and other type of bugs. The output is a four pandas dataframes that contain general information about the analyzed DockerHub image, information about installed packages, how outdated they are, their vulnerabilities and other kind of bugs.

How it works

ConPan workflow is very simple:

  • Pulls the Docker image.
  • Runs it and extract installed packages.
  • Tracks installed packages from their package managers.
  • Inspects their technical lag: checks if they are outdated and how much they are lagging behind the latest available versions.
  • Identifies vulnerable packages.
  • Identifies other kind of bugs for installed packages.


  • docker-ce
  • pandas>=0.22.0
  • requests>=2.18.2
  • psycopg2-binary>=2.7.4
  • psycopg2>=2.7.4
  • matplotlib
  • apt_pkg

How to install/uninstall

ConPan is developed and tested mainly on GNU/Linux platforms. Thus it is very likely it will work out of the box on any Linux-like (or Unix-like) platform, upon providing the right version of Python (3.5, 3.6).

To install, run:

$> git clone
$> python3 build
$> python3 install

To uninstall, run:

$> pip3 uninstall conpan

How to use

ConPan can be used from command line or directly from Python, both usages are described below.

You will need permission to use the Docker tool first.

From command line

Launching ConPan from command line does not require much effort.

$ conpan -p debian -c debian:buster-slim -d Path-to/data

From Python

ConPan can be embedded in your Python scripts. Again, the effort of using it is minimum.

#! /usr/bin/env python3
from conpan.conpan import ConPan

# With 2 parameters
image_community = 'weboaks/chromium-xvfb-node'
image_official = 'debian:buster-slim'
dir_data = 'Path-to/data/'

cp = ConPan(packages="debian", image=image_official, dir_data=dir_data)

# extracting all information
general_info, installed_packages, tracked_packages, vulnerabilities, bugs = cp.analyze()

# Extracting specific information
