Public bug reported: On a Ubuntu 16.04 server amd64 host, docker does not work inside of a (lxc or lxd) Ubuntu 14.04 guest.
I tested on both a clean Ubuntu 16.04 install and also one that was upgraded from Ubuntu 15.10. My definition of work is having the expected result when running --------------------------- sudo docker run hello-world --------------------------- If the guest containers is also Ubuntu 16.04, it works out of the box. The images were made either using lxc-create -t download -n test01 -- -d ubuntu -r trusty -a amd64 or on lxd following the syntax from https://www.stgraber.org/2016/03/11/lxd-2-0-introduction-to-lxd-112/ Just for further reference, If the host is 15.10, one can have docker inside of LXC containers if one does the following: a) on the host: add this to /etc/lxc/default.conf lxc.aa_profile = unconfined lxc.cgroup.devices.allow = a lxc.cap.drop = sudo mv /usr/share/lxc/config/common.conf.d/00-lxcfs.conf /usr/share/lxc/config/common.conf.d/00-lxcfs.conf.disabled iptables -L # really. this loads modules that the docker install needs to be happy ip6tables -L # really. this loads modules that the docker install needs to be happy create the guest with something like lxc-create -t download -n test01 -- -d ubuntu -r trusty -a amd64 b) on the guest sudo apt-get install curl apparmor cgroup-lite curl -fsSL https://get.docker.com/ | sudo sh # the docker from apt- get install docker.io does not work, sudo docker run hello-world I personally consider this bug very important because 15.10 will be unsupported in July, so not upgrading will become an insecure choice to make. If there is any way I can help you, please let me know.
