According to https://discuss.linuxcontainers.org/t/having-trouble-using-docker/383 it sounds like you might need to set security.nesting=true. Stop the container (lxc stop deploy-container), configure nesting on (lxc config set deploy-container security.nesting true as per https://insights.ubuntu.com/2015/10/30/nested-containers-in-lxd) and lxc start deploy-container.
