http request to https request using haproxy

Question

I have a situation where I want to redirect all the http requests to https request using haproxy. Let say, I have a server x where haproxy is installed and a server y where actual services are running (using ssl). Now, I want that the haproxy to accept http requests and forward it to the backend server via https. Kinda like this:

user <--(http)--> haproxy <--(https)--> actual service

what I have done so far is, frontend accepts http connection in port 8080 and it sends to its default-backend, in backend I have prepended "ssl verify none".

Using this, I could load the page from http but whenever I am submitting a request (say login), response is coming in http url and nothing works.

I don't know whether at all if this is possible.

Let me know if I need to provide more details on this.

Any light on this would be very kind.

Thanks in advance.

What is your config?

You might need specify port like this

server httpsserver 10.0.0.80:443 ssl verify none

A simple https server:

var express = require('express');
var https = require('https');
var fs = require('fs');
var bodyParser = require('body-parser');
var options = {
  key: fs.readFileSync('./client-key.pem'),
  cert: fs.readFileSync('./client-cert.pem')
};
var app = express();
app.use(bodyParser.json());
app.post('/post', function (req, res) {
  res.send(req.body);
});
https.createServer(options, app).listen(443);

POST:

curl -k -X POST https://127.0.0.1/post -d '{"a":"b"}' -H "Content-Type: application/json"                                                               
{"a":"b"}

HAProxy config:

global
    debug
defaults
    retries 3
    timeout client  300s
    timeout connect 300s
    timeout server  300s
frontend web
    bind *:8080
    default_backend app
backend app
    balance     roundrobin
    server httpsserver 127.0.0.1:443 ssl verify none

POST against HAProxy

curl -k -X POST http://127.0.0.1:8080/post -d '{"a":"b"}' -H "Content-Type: application/json"                                                                 
{"a":"b"}
