Format your config with 3 backticks to preserve spacing, which is important in yaml.

Enable Traefik debug log ([doc](https://doc.traefik.io/traefik/v3.4/observability/logs/#level)) and Traefik access log in JSON format ([doc](https://doc.traefik.io/traefik/v3.4/observability/access-logs/#format)).

Note that you would usually access the Traefik dashboard with full path `/dashboard/` ([doc](https://doc.traefik.io/traefik/v3.4/operations/dashboard/)).

Maybe check [simple Traefik example](https://github.com/bluepuma77/traefik-best-practice/tree/main/docker-traefik-dashboard-letsencrypt).

Note that this creates a false sense of security, as a Docker socket can not be made read-only:
