Help me to configure custom SSL certificate for a domain

Hello,

Thank you so much for the great opensource software.
I see a lack of documentation for custom SSL configuration.

I would like to configure my own SSL certificate for a domain.
But I could not get the configured domain.
Traefik always returns default SSL.

can anyone guide me to fix my issue?

I run everything on docker-compose file

Traefik YAML file:

version: "3.3"
services:
  traefik:
    image: "traefik:v2.0"
    container_name: "traefik"
    restart: always
    command:
      - "--global.sendAnonymousUsage=false"
      - "--api=true"
      - "--api.insecure=true"
      - "--api.dashboard=true"
      - "--providers.docker=true"
      - "--providers.docker.exposedbydefault=false"
      - "--entrypoints.web.address=:80"
      - "--entrypoints.websecure.address=:443"

    labels:
      - "traefik.enable=true"
      - "traefik.http.routers.traefik.rule=Host(`traefik.192.168.1.21.nip.io`)"
      - "traefik.http.routers.traefik.entrypoints=web"
      - "traefik.http.services.traefik.loadbalancer.server.port=8080"
    ports:
      - "80:80"
      - "443:443"
    volumes:
      - "/storage/docker/apps/traefik:/traefik"
      - "/var/run/docker.sock:/var/run/docker.sock:ro"

traefik directory:

$ cat /storage/docker/apps/traefik/file_provider.yaml 
tls:
  certificates:
    - certFile: /traefik/tls/nginx.cert
      keyFile: /traefik/tls/nginx.key
  stores:
    default: {}


$ tree  /storage/docker/apps/traefik/
/storage/docker/apps/traefik/
├── file_provider.yaml
└── tls
    ├── nginx.cert
    └── nginx.key

1 directory, 3 files

Nginx configuration with my custom SSL certificate:

version: '2.2'
services:
  nginx:
    image: "nginx:alpine"
    container_name: "nginx"
    labels:
      - "traefik.enable=true"
      - "traefik.http.routers.nginx.rule=Host(`nginx.192.168.1.21.nip.io`)"
      - "traefik.http.routers.nginx.tls=true"
      - "traefik.http.routers.nginx.tls.domains[0].main=nginx"
      - "traefik.http.routers.nginx.tls.domains[0].sans=nginx"
      - "traefik.http.routers.nginx.entrypoints=websecure"
      - "traefik.http.services.nginx.loadbalancer.server.port=80"

Thanks,

Hi @jkandasa , as underlined in the documentation for user-defined TLS configuration (ref. https://docs.traefik.io/v2.0/https/tls/#user-defined), you have to enable the file provider in Traefik and specify the file /storage/docker/apps/traefik/file_provider.yaml that you used for defining the tls certificates (or else, how Traefik can know the existence of this file?).
You only have one line to add to the command: directive of the traefik container:

 - --providers.file.filename=/storage/docker/apps/traefik/file_provider.yaml
