do need make changes in /lib/systemd/system/docker.service or in /etc/default/docker. there work around, i've read in few posts kubernetes has problem latest docker version.

any , suggestion on appreciated.

hostconfig deprecated in docker v1.12. kubernetes made corresponding switch deprecate hostconfig in v1.2, need newer version (v1.2+) kubernetes work docker v1.12.

another caveat coming kubernetes 1.4 release claims compatible docker v1.12. older versions of kubernetes not tested against docker v1.12. might better off using older version of docker, or switch kubernetes v1.4 beta.
