I have the requirement where I need to expose all my containers through a static public IP.
However, the static public IP cannot be host IP because host IP must be dynamic.
The 2 solutions I found is macvlan and linux secondary IP, but base on my understanding, they cannot fulfil my need.
with macvlan, each container will get individual IP. I need to access all container through the same IP.
with linux secondary IP, I can assign a single static IP which exclusive for my docker container. However, I didn’t found a way to manage the /etc/network/interface inside a docker container.
My question is:
- Is it possible to set all container using same ip using macvlan?
- Is there any way to manage
/etc/network/interface, include ifup and ifdown inside a docker container? - Is there any alternative method
