portmap doesn't fail if chain doesn't exist 
It turns out that the portmap plugin is not idempotent if its
executed in parallel.
The errors are caused due to a race of different instantiations
deleting the chains.
This patch does that the portmap plugin doesn't fail if the
errors are because the chain doesn't exist on teardown.

Build Status

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.
