There is a not-insignificant performance overhead for all containers (if
containerd is a child of Docker, which is the current setup) if rlimits are
set on the main Docker daemon process (because the limits
propogate to all children).
We recommend using cgroups to do container-local accounting.
This applies the change added in 8db61095a3d0bcb0733580734ba5d54bc27a614d
to other init scripts.
Note that nfile cannot be set to unlimited, and the limit
is hardcoded to 1048576 (2^20) , see:
