Dotnet-monitor graceful shutdown

[agobezy]

I've been looking into this issue for the entire day and wanted to get some advice.

Environment details:

1. Azure Kubernetes Cluster
2. Single pod running two containers (dotnet app and dotnet monitor)
3. Dotnet monitor image - mcr.microsoft.com/dotnet/monitor:8

Kubernetes allows you to run commands before a pod is terminated. The preStop is working on the dotnet app. The dotnet monitor stops instantly and leads to a server error.

Troubleshooting attempted:

1. Following https://pracucci.com/graceful-shutdown-of-kubernetes-pods.html and setting a terminationGracePeriod of 300 seconds

Can the dotnet monitor process gracefully shutdown instead of terminating instantly?
