Traefik Certificate Extractor

Tool to extract Let's Encrypt certificates from Traefik's ACME storage file.

Installation

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

Usage

python3 extractor.py [directory]

Default input directory is ./data. The output directories are ./certs and ./certs_flat. The certificate extractor will extract certificates from any JSON file in the input directory (e.g. acme.json), so make sure this is the same as Traefik's ACME directory.
