$ sudo ./ovs-docker
ovs-docker: Performs integration of Open vSwitch with Docker.
usage: ovs-docker COMMAND
Commands:
add-port BRIDGE INTERFACE CONTAINER [ADDRESS] [GATEWAY]
Adds INTERFACE inside CONTAINER and connects it as a
port
in Open vSwitch BRIDGE. Optionally, sets ADDRESS on
INTERFACE. ADDRESS can be in CIDR notation which
include a
'/' to represent network prefix length. GATEWAY is the
default gateway IP address of the given ADDRESS. e.g.:
ovs-docker add-port br-int eth1 c474a0e2830e
192.168.1.2/24
del-port BRIDGE INTERFACE CONTAINER
Deletes INTERFACE inside CONTAINER and removes its
connection to Open vSwitch BRIDGE. e.g.:
ovs-docker del-port br-int eth1 c474a0e2830e
del-ports BRIDGE CONTAINER
Removes all Open vSwitch interfaces from CONTAINER.
e.g.:
ovs-docker del-ports br-int c474a0e2830e
Options:
-h, --help display this help message.
