Docker cgroups setup
The guide (https://wiki.alpinelinux.org/wiki/Docker) said to update the /etc/cgcofnig.conf file in order to enable cgroup configs for containers, but it seems that the subcategories of cpuset are not loaded (not sure if this is a bug or what), the log said that cpuset.cpu was not enabled. _Adding cpuset.cpu = /cgroup/cpuset/cpuset.cpu it seems to work, cpuset = /cgroup/cpuset is not enough (maybe useless?).
