CNI plugins
Some CNI network plugins, maintained by the containernetworking team. For more information, see the individual READMEs.
Read CONTRIBUTING for build and test instructions.
Plugins supplied:
Main: interface-creating
bridge: Creates a bridge, adds the host and the container to it.
ipvlan: Adds an ipvlan interface in the container.
loopback: Set the state of loopback interface to up.
macvlan: Creates a new MAC address, forwards all traffic to that to the container.
ptp: Creates a veth pair.
vlan: Allocates a vlan device.
host-device: Move an already-existing device into a container.
Windows: windows specific
win-bridge: Creates a bridge, adds the host and the container to it.
win-overlay: Creates an overlay interface to the container.
IPAM: IP address allocation
dhcp: Runs a daemon on the host to make DHCP requests on behalf of the container
host-local: Maintains a local database of allocated IPs
static: Allocate a static IPv4/IPv6 addresses to container and it's useful in debugging purpose.
Meta: other plugins
flannel: Generates an interface corresponding to a flannel config file
tuning: Tweaks sysctl parameters of an existing interface
portmap: An iptables-based portmapping plugin. Maps ports from the host's address space to the container.
bandwidth: Allows bandwidth-limiting through use of traffic control tbf (ingress/egress).
sbr: A plugin that configures source based routing for an interface (from which it is chained).
firewall: A firewall plugin which uses iptables or firewalld to add rules to allow traffic to/from the container.
Sample
The sample plugin provides an example for building your own plugin.

# HOW TO EDIT THIS FILE:
# The "handy ruler" below makes it easier to edit a package description.
# Line up the first '|' above the ':' following the base package name, and
# the '|' on the right side marks the last column you can put a character in.
# You must make exactly 11 lines for the formatting to be correct. It's also
# customary to leave one space after the ':' except on otherwise blank lines.
