--domainname on the container sets the kernel domainname, which c-ares uses to infer a search domain even when /etc/resolv.conf has no search line. This caused c-ares to query github.com.casjay.work AAAA and get the host's own IPv6 address, routing all outbound HTTPS to the local nginx instead of the real server. Adding 'search .' and 'options ndots:0' explicitly disables search domain inference regardless of the kernel domainname setting. - rootfs/usr/local/etc/resolv.conf: add search . and options ndots:0 rootfs/usr/local/etc/resolv.conf
