Hi Nirav,
I am running ryu.topology.js module within a docker container that runs an
express server (front end) and connects with another container (that
executes ryu with ryu.topology module). I have imported:
├── router.svg
├── ryu.topology.css
├── ryu.topology.js
within the front end and connected the websocket with between front end and
ryu in order to get topology information:
within ├──* ryu.topology.js:*
*Can be improved, it was just a test.*
var wsRyu = new WebSocket(
"ws://ip-ryu-docker-container:8080/v1.0/topology/ws");
wsRyu.onmessage = function(event) {
var data = JSON.parse(event.data);
var result = rpc[data.method](data.params);
var ret = {"id": data.id, "jsonrpc": "2.0", "result": result};
this.send(JSON.stringify(ret));
}
elem.drag = elem.force.drag().on("dragstart", _dragstart);
function _dragstart(d) {
var dpid = dpid_to_int(d.dpid)
d3.json("http://ip-ryu-docker-container:8080/stats/flow/"; + dpid, function(e,
data) {
flows = data[dpid];
console.log(flows);
elem.console.selectAll("ul").remove();
li = elem.console.append("ul")
.selectAll("li");
li.data(flows).enter().append("li")
.text(function (d) { return JSON.stringify(d, null, " "); });
});
d3.select(this).classed("fixed", d.fixed = true);
}
function initialize_topology() {
d3.json("http://ip-ryu-docker-container:8080/v1.0/topology/switches";,
function(error, switches) {
d3.json("http://ip-ryu-docker-container:8080/v1.0/topology/links";, function(
error, links) {
topo.initialize({switches: switches, links: links});
elem.update();
});
});
}
Also, take a look at this:

Hope you find this useful
