NAME

       fence_docker - Fence agent for Docker

DESCRIPTION

       fence_docker is I/O fencing agent which can be used with the Docker Engine containers. You
       can use this fence-agent without any authentication, or you  can  use  TLS  authentication
       (use    --ssl    option,    more    info    about    TLS    authentication    in   docker:
       http://docs.docker.com/examples/https/).

       fence_docker accepts options on the command line as  well  as  from  stdin.  Fenced  sends
       parameters  through  stdin when it execs the agent. fence_docker can be run by itself with
       command line options.  This is useful for testing and for turning outlets on or  off  from
       scripts.
