defaultRule in docker provider raise error in fileProvider:

Traefik Traefik v2

Hi,

I noticed that introducing defaultRule parameter in my configuration :

  docker:                                                                     
    exposedbydefault: true                                                    
    network: "traefik_net"                                                    
    defaultRule: Host(`{{ normalize .Name }}`)

Or even commented out :

  docker:                                                                     
    exposedbydefault: true                                                    
    network: "traefik_net"                                                    
    #defaultRule: Host(`{{ normalize .Name }}`)

Fails my Fileprovider :

providers:
  # Enable the file provider to define routers / middlewares / services in a file
  file:
    filename: dynamic_conf.yml
    directory: "/etc/traefik/"
  docker:
    exposedbydefault: true
    network: "traefik_net"
    #defaultRule: Host(`{{ normalize .Name }}`)

With this error :


time="2019-11-10T18:57:42Z" level=error msg="Error occurred during watcher callback: /etc/traefik/traefik.yml: template: dynamic_conf.yml:25:37: executing \"dynamic_conf.yml\" at <.Name>: can't evaluate field Name in type bool" providerName=file

Is this a bug ? Or I missed something ?

I don't think that what you are describing is really happening. I think what's really happening is that you've done a bunch of changes and one of them made your configuration to fail parsing, but you singled out one, unrelated change to describe above.

Please post your entire configuration, and do some more debugging by re-creating all your containers from scratch, or make sure that this is not a watcher problem. (It should not be, but it's good to have a reliable reproduction).

When you post your debug logs makes sure to include the static configuration dumped in the first few lines after traefik starts. That makes it possible to compare your posted config, with what traefik actually sees. Any discrepancies may indicated mistakes in the configuration.

Here the configuration (With the line commented out) :

╰─# cat traefik.yml
defaultEntryPoints: ["http", "https"]

log:
  level: "DEBUG"

entryPoints:
  http:
    address: ":80"
  https:
    address: ":443"

api:
  dashboard: True
  insecure: False
  debug: True

providers:
  # Enable the file provider to define routers / middlewares / services in a file
  file:
    filename: dynamic_conf.yml
    directory: "/etc/traefik/"
  docker:
    exposedbydefault: true
    network: "traefik_net"
    #defaultRule: Host(`{{ normalize .Name }}`)

So now I restart Traefik container (with this configuration):

Where is the rest of your configuration?

5

As the message say: the error is in the dynamic_conf.yml file.

Also some note about your static configuration:

# `defaultEntryPoints` is a v1 configuration, not supported in v2
# defaultEntryPoints: ["http", "https"] 

log:
  level: "DEBUG"

entryPoints:
  http:
    address: ":80"
  https:
    address: ":443"

api:
  dashboard: true
  insecure: false
  # the `debug` option is for pprof https://docs.traefik.io/operations/api/#debug, so you don't need that
  # debug: true

providers:
  file:
    # you cannot use both (`filename` and `directory`), you need to choose only one.
    filename: dynamic_conf.yml 
    # directory: /etc/traefik/
  docker:
    # YAML is case sensitive
    # exposedbydefault: true
    exposedByDefault: true
    network: traefik_net
    #defaultRule: Host(`{{ normalize .Name }}.localhost`)

as @zespri says, could you provide more information:

  • docker-compose file
  • the dynamic_conf.yml file

Also could you explain what you are trying to do?

The below is what is usually useful for diagnosing, apologies for partial repetitions, but I did not figure out how to keep it coherent without:

  • Provide your traefik static configuration file if you are using it. It is usually, but not always called traefik.toml.
  • If you are not using Docker/Kubernetes/Etc, provide the command line you are using to start traefik.
  • If you are using docker, but not docker-compose provide the command line that you are using to start traefik container.
  • If you are using docker-compose, provide your docker-compose file usually it's called docker-compose.yaml or docker-compose.yml
  • If you are using docker swarm provide your compose file that you are using with docker stack deploy
  • If you are using Kubernetes, please provide manifests for all relevant objects. There is a good working example here. Often kubernetes configuration do not work not because of a mistake in an IngressRoute but in the way Kubernetes is deployed. So make sure to include all kubernetes objects that are relevant. Here is a short checklist, note that it is not exhaustive, and may vary depending on your deployment. Add anything that is not mentioned here but relevant too. Note that not all of those item may always be present in your installation
    • Traefik Deployment/DaemonSet object
    • Traefik Service(s)/Ingress(es)
    • Traefik CRDs
    • Traefik security objects such as CluserRole(s), ClusterRoleBinding(s) and ServiceAccount(s)
    • Your application Deployment(s) / Service(s) / Ingress(es) / IngressRoute(s)
  • If your configuration uses any other files, in particular, if you are using file provider to load additional configuration, please provide those files as well.
  • Please enable debug log and provide relevant log entries. Note that the complete debug log can be overwhelming to post (use gist or pastebin), yet it is important that relevant parts of it are included. Here are the most useful parts of the log to provide:
    • Traefik dumps its static configuration on strart up, and dynamic configuration whenever it's received from a proivder to the log. Dynamic configuration is dumped repeatedly whenever it is received from each of the providers you are using. It is extremely useful for diagnostics, to provide this, as we can compare the config (expected) to the dump (what traefik actually sees), any descripansice help identify configuration issues
    • Any records that have word "error" (any case) in it, and a sufficently large portion of the log immediately preceeding those lines

Hi,

Sorry for the late answer. I delayed a bit my project, changed some things and now I'm not able to reproduce anymore...

Thanks for your help around this issue, it helped me to make a cleaner configuration !

Regards,

Hi Everyone,

Iam able to reproduce this one.

this is my configuration:

[global]
  checkNewVersion = true
  sendAnonymousUsage = false
[entryPoints]
  [entryPoints.web]
    address = ":80"
  [entryPoints.websecure]
    address = ":443"
[log]
  level = "DEBUG"
[api]
  dashboard = true
  debug = true
[ping]
[providers]
[providers.docker]
  network = "traefik"
  exposedByDefault = false
[providers.file]
  filename = "/etc/traefik/traefik.toml"
  watch = true
[http.middlewares.auth.basicAuth]
  users = [
    "admin:$apr1$H6ussssW$IgYLP2ewrrSuBkTrqE8wj/",
  ]

i start the container using the following command:

docker run --rm --name traefik -it -p 80:80 -p 443:443 -p 8080:8080 -v /home/bob/traefik/traefik.toml:/etc/traefik//traefik.toml -v /var/run/docker.sock:/var/run/docker.sock:ro traefik:v2.2.0 --global.checkNewVersion=true --entryPoints.http.address=:80 --entryPoints.https.address=:443 --log=true --log.level=DEBUG --accessLog=true --providers.docker=true --providers.docker.swarmMode=false --label=traefik.enable=true --label="traefik.http.routers.http-catchall.entrypoints=http" --lable="traefik.http.routers.http-catchall.rule=HostRegexp(\`{host:.+}\`)" --label="traefik.http.routers.http-catchall.middlewares=redirect-to-https" --label="traefik.http.middlewares.redirect-to-https.redirectscheme.scheme=https"

and I get the following error while starting and a 404 for the dashboard

bob@hanibal:~/traefik$ docker run --rm --name traefik -it -p 80:80 -p 443:443 -p 8080:8080 -v /home/bob/traefik/traefik.toml:/etc/traefik/traefik.toml

I recommend to not use the same file for the static and the dynamic configuration.

also:

There are three different, mutually exclusive (e.g. you can use only one at the same time), ways to define static configuration options in Traefik:

So you cannot use CLI flags and file at the same time for the static configuration.

Hi @Idez,

thanks for the valid hint mixing command line and file direction is a no go! the confusion comes from the fact that i was not able to correctly escape labels and ends up with:

bob@hanibal:~/traefik$ docker run --rm --name traefik -it -p 80:80 -p 443:443 -p 8080:8080 
 -v /var/run/docker.sock:/var/run/docker.sock:ro traefik:v2.2.0 
 --global.checkNewVersion=true 
 --log=true --log.level=DEBUG 
 --accessLog=true 
 --providers.docker=true 
 --providers.docker.swarmMode=false 
 --entryPoints.http.address=:80 
 --entryPoints.https.address=:443 
 --label="traefik.enable=true"
 --label="traefik.http.routers.http-catchall.entrypoints=http" 
 --lable="traefik.http.routers.http-catchall.rule=HostRegexp(\`{host:.+}\`)" 
 --label="traefik.http.routers.http-catchall.middlewares=redirect-to-https" 
 --label="traefik.http.middlewares.redirect-to-https.redirectscheme.scheme=https"

2020/04/27 11:27:20 command traefik error: failed to decode configuration from flags: field not found, node: label
bob@hanibal:~/traefik$

so I switched to file providers hoping to identify the problem with CLI later

Thanks

You have to set the --label flags at the right place and beware of typos (lable -> `label)

docker run --rm --name traefik  -it \
 -p 80:80 -p 443:443 -p 8080:8080 \
 --label="traefik.enable=true" \
 --label="traefik.http.routers.http-catchall.entrypoints=http"  \
 --label="traefik.http.routers.http-catchall.rule=HostRegexp(\`{host:.+}\`)"  \
 --label="traefik.http.routers.http-catchall.middlewares=redirect-to-https"  \
 --label="traefik.http.middlewares.redirect-to-https.redirectscheme.scheme=https" \
 -v /var/run/docker.sock:/var/run/docker.sock:ro \
 traefik:v2.2.0 \
 --global.checkNewVersion=true \
 --log=true --log.level=DEBUG \
 --accessLog=true \
 --providers.docker=true \
 --providers.docker.swarmMode=false \
 --entryPoints.http.address=:80 \
 --entryPoints.https.address=:443

Thanks you @Idez
the typo is well spotted and the order of labels too!!
