 # Traefik Certificate Extractor
 
+Forked from [DanielHuisman/traefik-certificate-extractor](https://github.com/DanielHuisman/traefik-certificate-extractor)

 Tool to extract Let's Encrypt certificates from Traefik's ACME storage file. Can automatically restart containers using the docker API.
 
 ## Installation
 ```shell
-git clone https://github.com/DanielHuisman/traefik-certificate-extractor
+git clone https://github.com/snowmb/traefik-certificate-extractor
 cd traefik-certificate-extractor
 ```

 Example run:
 ```shell
 docker run --name extractor -d \
   -v /opt/traefik:/app/data \
   -v ./certs:/app/certs \
-  -v /var/run/docker.socket:/var/run/docker.socket \

 ```
 Mount the whole folder containing the traefik certificate file (`acme.json`) as `/app/data`. The extracted certificates are going to be written to `/app/certs`.

+The docker socket is used to find any containers with this label: `com.github.SnowMB.traefik-certificate-extractor.restart_domain=<DOMAIN>`.
 If the domains of an extracted certificate and the restart domain matches, the container is restarted. Multiple domains can be given seperated by `,`.
 
+You can easily use `docker-compose` to integrate this container into your setup:
+
+```yaml
+...
+services:
+  certs:
+     image: snowmb/traefik-certificate-extractor
+     volumes:
+      - path/to/acme.json:/app/data/acme.json:ro
+      - certs:/app/certs:rw
+      - /var/run/docker.sock:/var/run/docker.sock
+     command: -r --include example.com
+     restart: always
