REST API Plugin

The restplugin is a core Agent Plugin used of exposing REST API for the following:

• Run VPP CLI commands
• Exposes existing Northbound objects
• Provides logging mechanism so that the VPPCLI command and response can be searched in elastic search

VPP CLI commands

curl -H "Content-Type: application/json" -X POST -d '{"vppclicommand":"show interface"}' http://0.0.0.0:9191/

Exposing existing Northbound objects

curl http://0.0.0.0:9191/interfaces
curl http://0.0.0.0:9191/bridgedomainids
curl http://0.0.0.0:9191/bridgedomains
curl http://0.0.0.0:9191/fibs
curl http://0.0.0.0:9191/xconnectpairs
curl http://0.0.0.0:9191/staticroutes
curl http://0.0.0.0:9191/acl/interface/<if-sw-index>    // Get ACLs for interface <if-sw-index>
curl http://0.0.0.0:9191/acl/ip                         // Get all IP ACLs  
curl http://0.0.0.0:9191/acl/ip/example                 // Get an example ACL 

Configure an IP ACL:

curl -H "Content-Type: application/json" -X POST -d '<acl-json>' http://0.0.0.0:9191/interface/acl/ip

For example:

curl -H "Content-Type: application/json" -X POST -d '{
    "acl_name": "example"
    "rules": [
        {
            "rule_name": "acl1_rule1",                                                                                                        {                                                                                                                     "actions": {
            "acl_action": 1,
            "match": {
                "ip_rule": {
                    "ip": {
                        "destination_network": "1.2.3.4/24",
                        "source_network": "5.6.7.8/24"
                    },
                    "tcp": {
                        "destination_port_range": {
                            "lower_port": 80,
                            "upper_port": 8080
                        },
                        "source_port_range": {
                            "lower_port": 10,
                            "upper_port": 1010
                        },
                        "tcp_flags_mask": 255,
                        "tcp_flags_value": 9
                    }
                }
            }
        }
    ]
}' http://0.0.0.0:9191/interface/acl/ip

Logging mechanism

The REST API request is logged to stdout. The log contains VPPCLI command and VPPCLI response. It is searchable in elastic search using "VPPCLI".

Functions

func Asset

func Asset(name string) ([]byte, error)

Asset loads and returns the asset for the given name. It returns an error if the asset could not be found or could not be loaded.

func AssetDir

func AssetDir(name string) ([]string, error)

AssetDir returns the file names below a certain directory embedded in the file by go-bindata. For example if you run go-bindata on data/... and data contains the following hierarchy:

data/
  foo.txt
  img/
    a.png
    b.png

then AssetDir("data") would return []string{"foo.txt", "img"} AssetDir("data/img") would return []string{"a.png", "b.png"} AssetDir("foo.txt") and AssetDir("notexist") would return an error AssetDir("") will return []string{"data"}.

func AssetInfo

func AssetInfo(name string) (os.FileInfo, error)

AssetInfo loads and returns the asset info for the given name. It returns an error if the asset could not be found or could not be loaded.

func AssetNames

func AssetNames() []string

AssetNames returns the names of the assets.

func MustAsset

func MustAsset(name string) []byte

MustAsset is like Asset but panics when Asset would return an error. It simplifies safe initialization of global variables.

func RestoreAsset

func RestoreAsset(dir, name string) error

RestoreAsset restores an asset under the given directory

func RestoreAssets

func RestoreAssets(dir, name string) error

RestoreAssets restores an asset under the given directory recursively

Types

type Deps

type Deps struct {
	local.PluginInfraDeps
	HTTPHandlers rest.HTTPHandlers
	GoVppmux     govppmux.API
}

Deps represents dependencies of Rest Plugin

type Plugin

type Plugin struct {
	Deps
	// contains filtered or unexported fields
}

Plugin registers Rest Plugin

func (*Plugin) AfterInit

func (plugin *Plugin) AfterInit() (err error)

AfterInit is used to register HTTP handlers

func (*Plugin) Close

func (plugin *Plugin) Close() (err error)

Close is used to clean up resources used by Plugin

func (*Plugin) Init

func (plugin *Plugin) Init() (err error)

Init initializes the Rest Plugin
