helloworld

Documentation

Overview

The helloworld package implements an example charm that exposes an HTTP service that returns "hello, world" from every endpoint.

To deploy it, first build it:

gocharm github.com/juju/gocharm/example-charms/helloworld

Then deploy it to a juju environment and expose the service:

juju deploy local:trusty/helloworld
juju expose helloworld

Then, when the helloworld unit has started, find the public address of it and check that it works:

curl http://<address>/

The port that it serves on can be configured with:

juju set helloworld http-port=12345

It can also be configured to serve on https by setting the https-certificate configuration option to a PEM-format certificate and private key.

See http://godoc.org/github.com/juju/gocharm/example-charms/helloworld-configurable for a slightly more advanced version of this charm that allows the message to be configured.
