I am in the process of setting up a new ECS windows cluster in AWS.
While reading this piece of documentation I came across the AwsvpcAdditionalLocalRoutes option, but it is unclear to me what this option is for. I didn't manage to find any more info about it after some online searches.
Can someone explain why this option is available and describe the use-cases where it is meant to be used?
There seems little information for this option.
This docs says as follows and more understandable.
ECS_AWSVPC_ADDITIONAL_LOCAL_ROUTES Example values: ["10.0.15.0/24"]
Default value on Linux: []
Default value on Windows: []
In awsvpc network mode, traffic to these prefixes is routed via the host bridge instead of the task elastic network interface.
My understanding is that this option is used when you want to use bridge mode for specific ip address as well as awsvpc mode. Use case is for example you want to set up daynamic port mapping for the ip address. (Only bridge mode support dynamic port mapping. ref)
