Command line parameters moved to static file, they are now unrecognized

Traefik Traefik v3 (latest)
1

I moved from Caddy to Traefik configured via command in its docker compose. It worked.

I then decided to move the command line configuration to a configuration file, translating each of them. I ended up with the configuration file below, which seems to be only partially parsed:

  • the routers and services are started (which means the file itself is visible to Traefik)
  • ... but the entrypoints are not

I am sure this is a simple mistake from my side in organizing the file - I would appreciate any help with that.
Additionally, the dashboard is not available anymore.

The config file:

  sendAnonymousUsage: true

  insecure: true
  dashboard: true

You need to understand the difference between static and dynamic config. Static config is in traefik.yml or command:, dynamic config is different, either in separate dynamic config file loaded via providers.file in static config, or automatic via providers.docker

Ahhhh, OK, thanks! I thought that "static" means "file" and "dynamic" means "via (for instance) docker labels".

From what you are saying, there are directives that belong to the "static config" file and others that belong to another "static config" dynamic file. And in addition the docker labels.

Thanks a lot - I will look at the docs to see where this is documented.

This is a bit weird - I removed the command entries, set XDG_CONFIG_HOME and the configuration - as it was- worked.

I have to read more about that at Traefik Configuration Documentation - Traefik, though the wording is rather difficult to grok.

Maybe check some Traefik examples.

I will actually do a writeup about my mistakes and post it somewhere :slight_smile:
