Docker and network namespaces

General
1

I have a system which has a couple of network namespaces.

Problem 1:
I would like to be able to pull images from any of the namespaces using “docker pull”
Currently docker seems to see only the network namespace where docker was started in.

Problem 2:
I would like to run a container such that the host network it sees is a specific network namespace and not the network namespace where docker was started.

I’d suggest you take a look at https://platform9.com/blog/container-namespaces-deep-dive-container-networking/ or ask https://domyhomeworkonline.net/ for a help.
