• Cocaine Core
• Cocaine Runtime
• Cocaine Framework Python (with embedded cocaine proxy)

vagrant plugin install vagrant-berkshelf --plugin-version '>= 2.0.1'
  • Install Chef-DK from https://downloads.chef.io/chefdk

• Ruby 2.3+

Installation

git clone https://github.com/cocaine/cocaine-vagrant.git
cd cocaine-vagrant
vagrant up

Running Cocaine Cloud

• shell into the VM if you are not already there

vagrant ssh

Test Your Cocaine Cloud Instance

At this point, there is one application running - QR-code generator. To be sure, that it is running, type:

cocaine-tool info

The answer will be (approximately):

{
    "apps": {
        "qr": {
            "load-median": 0, 
            "profile": "default", 
            "sessions": {
                "pending": 0
            }, 
            "queue": {
                "depth": 0, 
                "capacity": 100
            }, 
            "state": "running", 
            "slaves": {
                "active": 0, 
                "idle": 1, 
                "capacity": 4
            }
        }
    }
}

In this example we provide embedded http proxy for Cocaine applications. Check if it is running:

sudo cocaine-tool proxy status

If the answer is something like Running: 4893 (pid number may vary) that's ok.

Finally, open your browser at your wish and type:

http://localhost:48080/qr/generate/?message=Hello,%20cocaine%20world!

The cloud application shows answer to you.
