Enable remote debugging with breakpoints with Minikube #4340
Description
Is your feature request related to a problem? Please describe.
This feature is not related to a problem but more likely to help debugging locally while implementing or debugging with agones locally.
Describe the solution you'd like
I would like to be able to build agones binaries, deploy them in minikube and being able to use the breakpoints from vscode to debug my containers running within minikube
Describe alternatives you've considered
- Debugging with more logs or connecting manually to the different pods, but it won't pause the flow where I want, that could be helpful for different scenarios
Additional context
The design would looks like this:
┌──────────────────────────────────────────┐

│ ┌──────────────────────────────────┐ │
│ │ Agones Pod │ │

│ │ ┌─────────────┐ ┌────────────────┐│
