From the perspective of a container, what is the IP address of the host?
For example, if I have a web app running on my host, what IP address can I use from inside a container to make a request to that web app? Thank you.
It depends. If the container uses NAT network, if host ip is 192.168.100.1 and web app bind at port 80, and container ip is 192.168.100.x, container can reach it via 192.168.100.1:80. If the container uses the bridge attached to same network as host, just use in same cidr host’s ip + 80. If macvlan, not reachable. I don’t know about other network types.
Thank you. In my case my container was using lxdbr0 and once I discovered my host IP I could reach it from the container.
