Running NodeJS Application in Cocaine

This tutorial shows how run your nodejs application using vagrant environment.

Tweak your app as needed

Let's consider a simple example. For full details what actions are needed and why see [nodejs-quick-start.md]

Let's say we want to run a simple http app like this:

var http = require("http")

var Server = new http.Server(function(rq, rs){
  rq.on("data", function(data){
    console.log(data)
  })
  rq.on("end", function(){
    rs.end("hi")
  })
  rq.on("error", function(err){
    console.log("error in request", rq, err)
  })
})
Server.listen(8080)

We add the following strings:

var cocaine = ...

Install vagrant

git clone ...
cd cocaine-vagrant
vagrant up

Push app to the image

git remote add ssh://ape@localhost:2222/app-name ape

The next string will push your code to vagrant image and build docker image.

git push ape master

You see the output of the build process. If there are any errors, correct them, and push again.

Finally, when the build succeds, you see something like

Start and test your app

ssh ape@localhost -p 2222 start ape-name master

ssh ape@localhost -p 2222 status ape-name master

The output should look like this

Now, since the port 8080 of vagrant image maps to 48080 on the localhost, we can reach our app like this:

curl -v http://localhost:48080/app-name/incoming-event-name/
