As far as I understand, you want to get a container to have access to the /etc/hosts of its host. For this to work, the host needs to make a special arrangement in order to make /etc/hosts available to the containers. 1. You might be able to do something like lxc config device add mycontainer etchosts disk path=/etc/hosts source=/etc/hosts which means that the container's /etc/hosts is actually the host's /etc/hosts. The LXD containers have a stock /etc/hosts, therefore on their part they do not need an individual special entry. 2. Instead of having these static entries (/etc/hosts), you can consider using a local DNS server. LXD uses already a separate DNS server (dnsmasq) for the containers, which by default resolves all those *.lxd hostnames.
