This is a Meteor (1.3+) package that provides a reactive wrapper around the npm packages - 'dockerode' (exposes Docker's API) and 'docker-events' (creates event emitter's on top of the API).
meteor add cunnagin:reactive-docker-status
Internally, a mongo collection called _dockerStatus is created and stores objects representing the status for each docker service being monitored. All monitoring occurs from the Meteor server.
In order to create a docker service object, simply make a call from your client (this actually calls a method stub on the server) as such:
dockerStatusCreate({host: argHostname, port: argPort, ca: argCa, cert: argCert, key: argKey, name: argName,})Where:
argHostName => (string, required) ...the desired docker hostname to monitor, e.g. 'http://my.dockerserver'
argPort => (string, optional) ...the port for the docker API, e.g. default is '2375'
argCa => fs pointer to a 'ca.pem' file [for SSL]
argCert => fs pointer to a 'cert.pem' file [for SSL]
argKey => fs pointer to a 'key.pem' file [for SSL]
argName => (string, optional) ...a simple name for this docker service object, e.g. default is '_dockerList'
The first 5 parameters are the same as for the 'dockerode' instantiation object (see their help files).
A few global Template helpers are available to help see the results:
dockerContainers()
dockerPrint(containerRecord)Here is an example JS and HTML file for the client to show how to use these:
Template.status.helpers({
dockerStatusCreate({host: 'http:///your.docker.hostname'})
})<!-- package: npm
end: client
