Hello,
I’m new to Traefik and might have made a few mistakes in my configuration.
My objective was to use Traefik as a reverse proxy for the other Docker containers running on my host. I’m managing containers with Portainer.
To start, let’s share my configuration files.
traefik-stack (docker compose file) :
services:
traefik-reverse-proxy:
image: traefik:latest
restart: unless-stopped
environment:
- TZ=Europe/Berlin
ports:
# The HTTP port
- "80:80"
# The HTTPS port
- "443:443"
# The Traefik port
- "8080:8080"
volumes:
- traefik-main-config:/etc/traefik/
- traefik-config-files:/etc/traefik/conf/
- traefik-ca:/etc/traefik/certs/
# So that Traefik can listen to the Docker events
- /var/run/docker.sock:/var/run/docker.sock:ro

I generated the certificates using my own PKI and exported them, along with their private key, to a .pfx file. Next, I converted them using OpenSSL with the following commands to create both a .crt and a .key file:
openssl pkcs12 -in "$Path\$CertName.pfx" -out "$Path\$CertName.crt" -clcerts -nokeys -passin pass:$CertPassword
openssl pkcs12 -in "$Path\$CertName.pfx" -out "$Path\$CertName.key" -nocerts -nodes -passin pass:$CertPassword
Finally, I copied the certificates to the traefik-ca volume.
Regarding my configuration, the main issue now is that Traefik isn’t using my certificates and is displaying the default Traefik certificate. What do I need to change to make my own certificates work with the services?
