Container lifecycle watcher and config distribution with websockets

npm install -g incureforce/argus-node.git

To launch it just argus-node in your favorite shell.

If argus-node finds a "app-shell.js" file it enters client mode, if not it enters server mode.

Sample app-shell.js for a web-app container.

When it launches it registers config values under service.proxy (hostname).

const os = require('os')

module.exports = {
    url: "http://argus/",

    startup: function (ctx) {
        ctx.update('services.proxy', {
            hostname: os.hostname()
        })
    },

    dispose: function (ctx) {
        ctx.update('services.proxy')
    },
}

Sample app-shell.js for a proxy container.

When it launches it fetches all config values under service.proxy and prints them to stdout. Every time a new clients connects we get a notify callback with all config values under serivce.proxy.

module.exports = {
    url: "http://argus/",

    startup: function (ctx) {
        ctx.notify('services.proxy', function (path, content) {
            console.log('notify', path, content)
        })
    },

    dispose: function (ctx) {
    },
}
