🐛 Graceful shutdowns shouldn't produce error logs

Describe the bug When i send a SIGTERM to my cloudflared tunnel run i get like 8-9 error logs.

To Reproduce Steps to reproduce the behavior:

1. Run cloudflared tunnel run $tunnel_id
2. Let is start fully
3. Call kill -15 $pid

Expected behavior I would expect a graceful shutdown didn't print error logs

That's true. Thanks for the report.

Would you like to open a PR to address this?

I think this is beyond my golang "skills".

I'll give it a go, but don't get your hopes up 🤣

Does this still need to be fixed? I can give it a go

It's present in 2023.8.2, which is the latest version. @Lumexralph

Here is how we deploy the tunnel in docker swarm

services:

  cloudflared:
    image: cloudflare/cloudflared:2023.8.2
    command: tunnel run ${TUNNEL_UUID}
    configs:
      - source: cloudflared-cred-file
        target: /etc/cloudflared/${TUNNEL_UUID}.json
    environment:
      TUNNEL_URL: http://webserver:80
    deploy:
      update_config: { order: start-first, parallelism: 0 }

I don't know if anyone from Cloudflare can give more insights on this before jumping into the wild
