lighty-controller-springboot-netconf

lighty.io SpringBoot integration example

This is simple demo application which uses Lighty with NETCONF Southbound plugin inside Spring Boot.

Application initializes OpenDaylight core components (MD-SAL, yangtools and controller) and NetConf Southbound plugin inside spring framework environment.

There is initialized fully functional md-sal inside the spring. The DataBroker is provided for SpringBoot dependency injection subsystem services and used in exposed REST endpoints. The REST endpoints provides very simple functionality for network-topology model inside global datastore.

Alongside the basic data broker, there is also integrated NETCONF Southbound plugin and some very basic NetConf functionality exposed through REST endpoints. The "lighty-toaster-device" was used as a NetConf device which uses toaster model from ODL repository.

Security

This demo utilizes Spring's method security and jCasbin. Web layer injects spring SecurityContext so it is available for other beans in application.

• Authentication is handled by internal service io.lighty.core.controller.springboot.services.UserAccessService using internally stored uername / password credentials.
• Authorization is handled by jCasbin library using RBAC model example in combination with Spring's Method Security.
  • authorization model definition
  • authorization policy definition

Users available

This demo requires username / password access, following users are available

• userName="bob", password="secret", roles={ ROLE_USER, ROLE_ADMIN }
• userName="alice", password="secret", roles={ ROLE_USER }

Build

mvn clean install

Start

It is necessary to copy toaster@2009-11-20.yang file to $WORKING_DIR/cache/schema/toaster@2009-11-20.yang, to be possible to read NETCONF data from testing device (lighty-toaster-device).

mvn spring-boot:run

or

java -jar target/lighty-controller-springboot-21.0.0-SNAPSHOT.jar

or in any IDE, run main in

io.lighty.core.controller.springboot.MainApp

Using REST APIs

Protected data is accessible only after login. After login, each request must use same cookie JSESSIONID, because server is tracking http sessions by this cookie. When application has started, the REST endpoints are provided:

POST /services/security/login

Login with username password, see Users available section. This request must be first one in order to use session cookie for consequent requests.

curl -i -X POST \
-c /tmp/lighty.cookies.txt \
-H "Content-Type:application/json" \
--data \
'{
    "username": "bob",
    "password": "secret"
}' \
"http://localhost:8888/services/security/login"

GET /services/data/topology/list

list all topology IDs stored in datastore

curl -i -b /tmp/lighty.cookies.txt \
-X GET "http://localhost:8888/services/data/topology/list"

PUT /services/data/topology/id/{topologyId}

create new topology with topology id "test-topology-id"

curl -i -b /tmp/lighty.cookies.txt \
-X PUT "http://localhost:8888/services/data/topology/id/test-topology-id"

DELETE /services/data/topology/id/{topologyId}

delete existing topology with topology id "test-topology-id"

curl -i -b /tmp/lighty.cookies.txt \
-X DELETE "http://localhost:8888/services/data/topology/id/test-topology-id"

GET /services/data/netconf/list

list all NETCONF devices with its connection status and "darknessFactor" data loaded from device (darknessFactor is contained in toaster model from ODL)

curl -i -b /tmp/lighty.cookies.txt \
-X GET "http://localhost:8888/services/data/netconf/list"

PUT /services/data/netconf/id/{netconfDeviceId}

attempt to connect to device "test-device" with specific credentials and address:port

curl -i -X PUT \
-b /tmp/lighty.cookies.txt \
-H "Content-Type:application/json" \
--data \
'{
    "username": "admin",
    "password": "admin",
    "address": "127.0.0.1",
    "port": "17830"
}' \
"http://localhost:8888/services/data/netconf/id/test-device"

DELETE /services/data/netconf/id/{netconfDeviceId}

disconnect NETCONF device "test-device"

curl -i -b /tmp/lighty.cookies.txt \
-X DELETE "http://localhost:8888/services/data/netconf/id/test-device"

GET /services/security/logout

logout current https session

curl -i -b /tmp/lighty.cookies.txt \
-X GET "http://localhost:8888/services/security/logout"
