Side note: (although that’s likely not an issue in this specific case) Sometimes, there are also incompatibilities between Docker and LXC, since both rely on some of the same kernel features such as namespaces and cgroups This overlap is one of the main reasons why running Docker inside LXC containers is generally not recommended.
