Intermittant startup issues

[Gordonby]

Describe the problem

I'm experiencing intermittent issues starting the minecraft server.

It seems to start fine, and the minecraft clients see that it's up and reporting a good ping. However occasionally they don't progress past the "Connecting to external server" dialog.

Here's the log

time="2022-10-15T10:01:44Z" level=debug msg="Using /data to match uid and gid"
time="2022-10-15T10:01:44Z" level=debug msg="Resolved UID=0 from match path"

I can see from the server metrics that when i have this problem the network bytes crash to0. Whereas when it starts successfully the behaviour is a little different.

I don't seem to have a server.log file created that i can access.

The compute is running, and i can ssh in and run bash commands.

Are there any commands i can run inside the container to do further diagnosis or prod the server back to life?

I’m going to convert this to a discussion and see if anybody has network troubleshooting advice for this.

I've switched the compute to Kubernetes, and I'm finding its now stable.
