Shuffle/Shuffle-docs#171 please close as you close this.

my concerns i would want you to review start here:

Shuffle/functions/onprem/orborus/orborus.go

Line 227 in fddca01

targetInterface := interfaces[1]

my assumption is that in the container, the first network interface after loopback is the best way to spot the docker bridge network. this is an observation i made. i don't know when it would change. you will have to give some feedback on the consistency of this.

i am also thinking of checking once if the network interface contains "eth0" since it does till a certain part.

Submit review!!

Would test this and make sure it's somewhat ready for prod. Be ready to see it break however. Quite unsure about the network interface naming however if chatGPT isn't hallucinating:

When a container is started, Docker creates a network namespace for that container, isolating its network stack from the host and other containers. Within the container's network namespace, Docker creates a virtual Ethernet interface that connects to the bridge network interface (docker0) on the host. This interface is typically named eth0.

If a container is connected to multiple networks, additional virtual Ethernet interfaces are created, and they are named sequentially as eth1, eth2, and so on.

I referred to this pattern in the code. Will test it by tomorrow so you can put it to prod.

https://medium.com/@diegogabrielschurch/how-docker-network-works-bridge-driver-e4819459cc8a this article does make me a little bit more clear. but i know we will break something :)

Docker by default creates rules to redirect the packages that go throw docker0 to eth0 interface. Also, creates a NAT over our docker networks to make them behave like private networks and block access from outside of the network.

This definitely makes me feel more confident in nothing messing up.

Ready for merge. Let's break things.

Looks better! Covering all bases with a fallback
