Hi, I’m using the default network configuration from LXD with lxcbr0 and 10.0.3.* IP range.
If I create multiple containers (ubuntu:14.04) then I am able to contact these containers from within each other by hostname. e.g. container1 container2 container3 Within container2 I can simply run ‘ping container1’ and it manages to resolve the IP without any further configuration. However, if I then delete container1 and re-create it, the IP address of container1 may change (via DHCP) and when I try to ping container1 from container2 I simply receive “ping: unknown host container1”. I’m not sure what the intended behaviour is here, I was really happy when I realised I could simple communicate between containers by container name (host name), but now I’m not so sure it is a reliable method. Could someone outline the intended behaviour here, and perhaps recommend a more reliable way of container to container communication without relying on knowing the IP addresses? Thanks, Jamie
