Also I would like to point out that the lxd community is helpful, engaging and absolutely wonderful. I had an issue with client ip address in haproxy container on Google compute instance you can see on https://discuss.linuxcontainers.org/t/how-to-get-real-client...
An issue was created and to my surprise a fix landed in next release. It helped me to launch haproxy containers binding port 80/443 on compute instance and have correct client ip in haproxy logs. This helped me to have analytics from haproxy logs directly.
