What should we do with Traefik v1? #22

Traefik v1 is our current load balancer.
It has multiple problems:

  • It is not maintained anymore
  • It has a weird bug where it stops accepting connections sometimes (fixed by Nomad monitoring that automatically restart it)
  • It takes around one minute to refresh after a configuration change. During that time, the impacted website will return a 404
  • Its cluster certificate management mode through Consul is broken (we had a bug where we had a deadlock)

Here are the following considered solutions:

  • Migrate to Traefik v2 but...
    • We need to rewrite our configurations
    • Cluster certificate management is not anymore available in the FOSS version
    • (We do not have a way to provision certificates for other services like postfix)
  • Fork Traefik v1
    • Delete what we do not use
    • Fix cluster certificate management
    • Maintain it forever
    • Will keep the lag of one minute (or we will need to fix it)
  • Code our own RP in Rust
    • See how we want to manage certificates
    • Use an ACME lib + a Consul lib + an HTTP lib
    • Maintain it forever
