Save Configuration & Build New Kernal
# make kernel and modules
make && make modules_install
# mount /boot only if 'noauto' option is set in the file '/etc/fstab'
mount /boot
# copy new kernel file to /boot, 'cp' command is another way
make install
# regenerate grub2 boot menu
grub-mkconfig -o /boot/grub/grub.cfg
Install Packages
# search the package name with keyword 'docker'
emerge -s docker
# install the packages with full dependence
emerge -avt app-containers/docker
