I am building a CI/CD for a CDN which is using anycast.
I would like to give two ip of the same docker network to an ubuntu 18.04 container.
For example I created this network:
docker network create -d bridge --subnet 192.168.242.0/24 --gateway 192.168.242.1 test_net
Now I connect my container to this network when I run it by adding
--network test_net --ip 192.168.242.2
At this point my container have ip 192.168.242.2 on eth0.
How can I give ip 192.168.242.3 on eth1 for example on an ubuntu 18.04 container image ?
When I run
docker network connect test_net my_container, I got an error because my container is already attached to this network. I also tried to give two
--ip flag at the creation of the container but it doesn’t work too.
Moreover how can I add a loopback ip to my container ? for example lo:1 22.214.171.124 netmask 255.255.255.255
Thanks for your help
