1. Install boot2docker
2. Install docker-compose:

pip install docker-compose

1. Clone this repo, run consul

git clone [email protected]:micahhausler/consul-demo.git
cd consul-demo/
docker-compose build

See the UI

http://192.168.59.103:8500/ui/

Interact

Check out the IPython notebook Consul by running:

pip install -r python_app/requirements.txt
ipython notebook --no-browser

and navigate to /notebooks/Consul.ipnb

Query the DNS API

You can query the consul DNS API once your containers are up by running:

dig @$(boot2docker ip) PythonApp.service.consul +tcp

consul-demo's Issues

app2 is not monitored

It seems like the health of the app2 service is not monitored properly. Even when I stop the container it's running in the consul-ui shows no problems.
As a matter of fact I don't see a way for consul to see that problem - it seems like port 8081 is not mentioned anywhere. Am I wrong?

As is after checkouting the project, I can not bring the Consul cluster UP.
