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.
Thanks
Marcos
