First Traefik config - invalid syntax error

alxsch · April 29, 2020, 8:49am

I think I'm really close to getting it working. I'm just getting an invalid syntax error now when i boot it up as a docker stack. Seems like using a docker secet as the api key.

version: '3.7'
services:
    traefik:

Hello,

there are some invalid and invisible chars in the value of traefik.http.middlewares.custom.headers.stsSeconds

Also you need to define a certificate resolver.

I have removed the invalid characters in traefik.http.middlewares.custom.headers.stsSeconds.
How might I go on to define a certificate resolver?
Like this? I want it to generate a certificate for services that I put on the public internet using subdomains.

            - "--certificatesresolvers.leresolver.acme.dnschallenge=true"
            - "--certificatesresolvers.leresolver.acme.dnschallenge.provider=cloudflare"
            - "--certificatesresolvers.leresolver.acme.email=${CF_API_EMAIL}"
            - "--certificatesresolvers.leresolver.acme.storage=/etc/traefik/acme/acme.json"

I am still getting this error:

traefik_traefik.1.5so5xju7db80@SERVER01    | time="2020-04-29T18:08:57-04:00" level=error msg="strconv.ParseInt: parsing \"\\u202d\\u202a157788000\\u202c\\u202c\":invalid syntax" providerName=docker container=traefik-traefik-1-5so5xju7db80smhgbll2fzya4-9d33b70c007d71fbc021137a1b0e0d2bbd8a84d94c4ab9c3ed826fedcf58a5b8

I recommend to copy-paste my version of your file.

Looks like just one more issue.

You have to replace example.com by your domain.

I did that but I think I haven't completely removed dns responsibilities from a web host im using for another page. Im guessing they are butting heads?

My acme file shows: after the private key and account.

"KeyType": "4096"
    },
    "Certificates": null
  }

After adding to the stack I now get the error:
