Since Docker 1.10 (and libnetwork update) we can manually give an IP to a container inside a user-defined network, and that’s cool !
I want to give a container an IP address in my LAN (like we can do with Virtual Machines in “bridge” mode). My LAN is 192.168.1.0/24, all my computers have IP inside it. And I want my containers having IPs in this range, in order to reach them from anywhere in my LAN (without NAT/PAT/etc…) just like if it was any computer.
I obviously red Jessie Frazelle’s blog post and a lot of others post here and everywhere.
Reading Jessie Frazelle’s blog post, I thought (since she use public IP) we can do what I want to do ?
Indeed, if I do something like :
network create --subnet 192.168.1.0/24 --gateway 192.168.1.1 homenet docker run --rm -it --net homenet --ip 192.168.1.100 nginx
The new interface on the docker host (br-[a-z0-9]+) take the ‘–gateway’ IP, which is my router IP. And the same IP on two computers on the network… BOOM
Thanks in advance.
