[BUG] Docker Log File Large with Errors

[myxxmikeyxx]

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior

The log file keeps growing rapidly with this:

[IMYVG] 2024/03/21 10:32:37 INFO: Relay listener (dynamic+https://relays.syncthing.net/endpoint) starting [IMYVG] 2024/03/21 10:32:47 INFO: Relay listener (dynamic+https://relays.syncthing.net/endpoint) shutting down [IMYVG] 2024/03/21 10:32:47 INFO: listenerSupervisor@dynamic+https://relays.syncthing.net/endpoint: service dynamic+https://relays.syncthing.net/endpoint failed: Get "https://relays.syncthing.net/endpoint": dial tcp: lookup relays.syncthing.net on 192.168.0.254:53: read udp 172.17.0.8:38656->192.168.0.254:53: i/o timeout

Expected Behavior

Should be a small log file or some way to limit the log file size.

Steps To Reproduce

I am not sure what steps I did. I had this setup on my old network but have changed my network and have not had a chance to check the error but I am using 10.0.X.X not 192.168.X.X
I am not sure if I can create and environment variable to do this command that docker supports
--log-opt max-size=50m

Environment

- OS: unriad
- How docker service was installed:
Community Apps on unraid

CPU architecture

x86-64

Docker creation

Not sure what unraid runs to start the container.

Thanks for opening your first issue here! Be sure to follow the relevant issue templates, or risk having this issue marked as invalid.

Not sure about unraid but it looks like there may be a DNS problem here, can you exec into the container to see if you can do DNS lookups?

[myxxmikeyxx]

@homerr I can exec into the container but I am not sure what you mean when you say DNS lookup

[homerr]

Do this;

docker exec -ti <containername> bash
nslookup relays.syncthing.net
nslookup google.com

See what comes back. Do you have any other containers you're running?

[myxxmikeyxx]

@homerr I just opened the container console and typed the commands from the unriad UI. Response is appended.

I might have figured out what it was. It was starting up before my VM with my my router. It was not getting a valid IP so it was throwing all sorts of problems. I just need to make sure to restart it after X amount of time. Not sure if unraid supports delayed start on docker containers.

Correct me if this sounds wrong.

[homerr]

That does sound quite plausible to be fair, not sure how you can do that you could ask in our discord there's a few unraid users around who may be able to help. Glad you sorted it!
