coreos

the missing CoreOS cli for creating and managing clusters on different providers

Warning:

Currently we only support Microsoft Azure Cloud. Feel free to PR your own account provider class.

Cli

Installation

npm install --global coreos

Usage

Please check --help with cli for further details.

coreos --help

Examples:

# Change to home dir so we can save config on "~/.coreos.json" 
cd ~;
 
# Add an Azure Account 
coreos account add \
    --provider="Azure" \
    --subscription="xxxx-xxxxx-xxxxxxx...." \
    --pem="/your/path/to/cer.pem";
 
# Say to CoreOS instance we will use this on next commands 
coreos account setCurrent \
    --account="{account-id}"
 
# Now, lets say we want to add an azure-based node into our cluster 
coreos node create \
    --location="West US"
 
# for instance you may want to access to node shell 
coreos node ssh --node="{nodeid}"
 
# Or execute a command with local files (example, submitting an unit) 
coreos node exec -- fleetctl submit :/my/local/unit.service
 
# Its easy right? If you think so, star this project!

Node.js / io.js

Installation

npm install --save coreos

Usage

Please check API for further methods details.

Examples:

var CoreOS = require( 'coreos' );
var cos = new CoreOS({
        // Don't read configuration file
        loadConfigOnInit: false,
    });
 
// Add an Azure Account
var azure = new CoreOS.Account.Provider.Azure(
        {
            subscription: 'xxxx-xxxxx-xxxxxxx....',
            pem: fs.readFileSync( '/your/path/to/cer.pem' );
        },
 
        // Notice we are passing current CoreOS instance
        cos
    );
 
// Say to CoreOS instance we will use this
// on next commands
azure.setAsCurrent();
 
 
// Now, lets say we want to add an azure-based node
// into our cluster
 
cos.nodeCreate({
    location: 'West US',
})
 
// As it returns a promise (hell yeah!!), we can then
// do something with node's info
.then(function ( node ) {
    console.log( node );
});
 
 
// Its easy right? If you think so, star this project!

Motivation

findhit entered Microsoft BizSpark program recently and we ended up choosing CoreOS as our cloud cluster OS. We did a bunch of internal bash scripts for handling cluster scaling and its resources but it ended up too hard to maintain.

As CTO, I've decided to create a cli manager as our scaling endpoint.
