I may have missed something - maybe you have configured clustering with KV storage etc - but I don't see it in the info you've provided so far. Finally, we're giving this container a static name called traefik. Please check the configuration examples below for more details. When running Traefik in a container this file should be persisted across restarts. Do new devs get fired if they can't solve a certain bug?

When both container labels and segment labels are defined, container labels are just used as default values for missing segment labels but no frontend/backend are going to be defined only with these labels. Learn more in this 15-minute technical walkthrough. If Let's Encrypt is not reachable, these certificates will be used : ACME certificates already generated before downtime Expired ACME certificates Provided certificates Note Default Trfik certificate will be used instead of ACME certificates for new (sub)domains (which need Let's Encrypt challenge).

How can I use "Default certificate" from letsencrypt? Depending on how Traefik Proxy is deployed, the static configuration for the certificate resolvers can be: Certificate resolvers using the TLS-ALPN-01 challenge will have the tlsChallenge configuration key that might look like this: If using command-line arguments, it might look like this: See our configuration documentation to find which type of static configuration your environment uses.

ACME certificates can be stored in a KV Store entry. Please note that multiple Host() matchers can be used) for specifying multiple domain names for this router. We tell Traefik to use the web network to route HTTP traffic to this container. So each update of record name must be followed by an update of the HURRICANE_TOKENS variable, and a restart of Traefik. We can install it with helm. Also, I used docker and restarted container for couple of times without no lack. Why is there a voltage on my HDMI and coaxial cables?
