Traefik v2 Certificate (let's encrypt) Explorer

Traefik has a nice feature of generating certificates for the host on the fly using lets encrypt. All the generated certificates are stored in acme.json format. This app uses (only reads) that file to provide a visual representation of the certificates & private keys and provides an easy way to inspect and export a PEM format for use in other paces.

HINT: Sending Accept: application/json header will return JSON representation of the page.

Quick Start

$ docker run -p 8884:8884 -v /path/to/your/acme.json:/data/acme.json hertzg/traefik-certificate-explorer

UI/UX is very rough, just enough to be usable for now (PRs are welcome).

JSON responses

To receive a JSON response you use the same URL's while browsing, but send Accept: application/json header.

hertz@potato:~$ curl -H "Accept: application/json" -vvv http://localhost:8884/
> GET / HTTP/1.1
> Host: localhost:8884
> User-Agent: curl/7.68.0
> Accept: application/json
>
