Traefik SSL Issue in version 2.1.4

Question

I have a docker swarm cluster. In that cluster, I need to configure Traefik with an SSL entry-point. once I applied my configuration into the traefik it gets some error. Please help me to troubleshoot this issue.

Here is my .toml file,

logLevel = "INFO"

[docker]
  endpoint = "unix:///var/run/docker.sock"
  exposedbydefault = false

[api]
  dashboard =true

[entryPoints]
  [entryPoints.http]
  address = ":80"
    [entryPoints.http.redirect]
    entryPoint = "https"
  [entryPoints.https]
  address = ":443"
    [entryPoints.https.tls]
      [[entryPoints.https.tls.certificates]]
      certFile = "/root/ssl/mi-synergy.com.crt"
      keyFile = "/root/ssl/mi-synergy.com.key"

Answer 1

you can try the following docker stack

version: "3.7"
services:
  traefik:
    image: traefik:2.1.4
    command:
      - '--providers.docker=true'
      - '--providers.providersThrottleDuration=2s'
      - '--providers.docker.watch=true'
      - '--providers.docker.swarmMode=true'
      - '--providers.docker.swarmModeRefreshSeconds=15s'
      - '--providers.docker.exposedbydefault=false'
      - '--providers.docker.defaultRule=Host("${REPLACE_WITH_YOUR_DOMAIN}")'
      - '--accessLog.bufferingSize=0'
      - '--api=true'
      - '--api.dashboard=true'
      - '--api.insecure=true'
      - '--ping.entryPoint=web'
      - '--providers.file.filename=/run/traefik.toml'
      - '--entryPoints.web.address=:80'
      - '--entryPoints.websecure.address=:443'
    volumes:
      - '/var/run/docker.sock:/var/run/docker.sock:ro'
      - '/root/traefik.toml:/run/traefik.toml'
      - '/root/ssl:/root/ssl'
    networks:
      - webgateway
      - traefik
    ports:
      - 80:80
      - 443:443
      - 8080:8080
    deploy:
      labels:
        - traefik.enable=true
        - traefik.docker.network=traefik
        - traefik.http.middlewares.https_redirect.redirectscheme.scheme=https
        - traefik.http.middlewares.https_redirect.redirectscheme.permanent=true
        - traefik.http.routers.http_catchall.rule=HostRegexp(`{any:.+}`)
        - traefik.http.routers.http_catchall.entrypoints=web
        - traefik.http.routers.http_catchall.middlewares=https_redirect
      mode: global
      placement:
        constraints:
          - node.role == manager
      update_config:
        parallelism: 1
        delay: 10s
      restart_policy:
        condition: on-failure

networks:
  webgateway:
    driver: overlay
  traefik:
    driver: overlay

traefik.toml

[[tls.certificates]]
  certFile = "/root/ssl/mi-synergy.com.crt"
  keyFile = "/root/ssl/mi-synergy.com.key"

make sure that the ssl certs exist on the host machine under /root/ssl and traefik config file under /root/traefik.toml otherwise, it will not be available to the container. if you are running this in a multi-node swarm it should be in every nodes (not only the manager) since you used global deployment mode
