Configuration

antrea-agent

Command line options

--config string                    The path to the configuration file
--v Level                          number for the log level verbosity

Use antrea-agent -h to see complete options.

Configuration

The antrea-agent configuration file specifies the agent configuration parameters. For all the agent configuration parameters of a Linux Node, refer to this base configuration file. For all the configuration parameters of a Windows Node, refer to this base configuration file.

antrea-controller

Command line options

--config string                    The path to the configuration file
--v Level                          number for the log level verbosity

Use antrea-controller -h to see complete options.

Configuration

The antrea-controller configuration file specifies the controller configuration parameters. For all the controller configuration parameters, refer to this base configuration file.

CNI configuration

A typical CNI configuration looks like this:

  {
    "cniVersion":"0.3.0",
    "name": "antrea",
    "plugins": [
      {
        "type": "antrea",
        "ipam": {
          "type": "host-local"
        }
      },
      {
        "type": "portmap",
        "capabilities": {
          "portMappings": true
        }
      },
      {
        "type": "bandwidth",
        "capabilities": {
          "bandwidth": true
        }
      }
    ]
  }

You can also set the MTU (for the Pod's network interface) in the CNI configuration using "mtu": <MTU_SIZE>. When using an antrea.yml manifest, the MTU should be set with the antrea-agent defaultMTU configuration parameter, which will apply to all Pods and the host gateway interface on every Node. It is strongly discouraged to set the "mtu" field in the CNI configuration to a value that does not match the defaultMTU parameter, as it may lead to performance degradation or packet drops.

Antrea enables portmap and bandwidth CNI plugins by default to support hostPort and traffic shaping functionalities for Pods respectively. In order to disable them, remove the corresponding section from antrea-cni.conflist in the Antrea manifest. For example, removing the following section disables portmap plugin:

{
  "type": "portmap",
  "capabilities": {
    "portMappings": true
  }
}
