Traefik Certificate Extractor

Forked from SnowMB/traefik-certificate-extractor

Tool to extract Let's Encrypt certificates from Traefik's ACME storage file. Can automatically restart containers using the docker API.

Note: This version differs from original in that:

• Changed requirements.txt to use watchdog instead of watchdog3 which doesn't appear to exist any more
• Support for ACME v1 has been removed. You must be using the acme_v2 url in your resolver(s)
• Added support for multiple resolvers
• An initial dump of the certs will be performed before starting to watch the acme.json file for changes

Installation

git clone https://github.com/raph2i/traefik-certificate-extractor
cd traefik-certificate-extractor

Usage

usage: extractor.py [-h] [-c CERTIFICATE] [-d DIRECTORY] [-f] [-r] [--dry-run]
                    [--include [INCLUDE [INCLUDE ...]] | --exclude
                    [EXCLUDE [EXCLUDE ...]]]

Extract traefik letsencrypt certificates.

optional arguments:
  -h, --help            show this help message and exit
  -c CERTIFICATE, --certificate CERTIFICATE
                        file that contains the traefik certificates (default
                        acme.json)
  -d DIRECTORY, --directory DIRECTORY
                        output folder
  -f, --flat            outputs all certificates into one folder
  -r, --restart_container
                        uses the docker API to restart containers that are
                        labeled accordingly

Docker

There is no image on hub.docker.com for this fork. Feel free to build your own by cloning this repository and using the included Dockerfile. It ought to work. Maybe.
