on faas-cli -action deploy: dial tcp 127.0.0.1:8080: getsockopt: connection refused

When attempting to deploy a function with faas-cli -action deploy -f ./urlping.yaml I get the following error message:

~/github/faas-cli$ sudo ./faas-cli -action deploy -f ./urlping.yaml 
Deploying: url_ping.
Error removing existing function: Delete http://localhost:8080/system/functions: dial tcp 127.0.0.1:8080: getsockopt: connection refused, gateway=http://localhost:8080, functionName=url_ping
Is FaaS deployed? Do you need to specify the -gateway flag?
Post http://localhost:8080/system/functions: dial tcp 127.0.0.1:8080: getsockopt: connection refused

The file, urlping.yaml, is as described in the README.md example file.

This happens with both the faas-cli downloaded from https://cli.openfaas.com, or one which I have compiled from this repo.

Expected Behaviour

Deploys function

Current Behaviour

Produces output pasted above

Possible Solution

Steps to Reproduce (for bugs)

1. Follow readme until faas-cli -action deploy -f ./urlping.yaml
2. run faas-cli -action deploy -f ./urlping.yaml

Update - This error is due to a docker stack not being deployed on localhost:8080, or another docker service already occupying that address and port. I had a service running on localhost:8080, so I removed it, and ran the ./deploy_stack.sh script in the faas/ repository, which set up a single node docker swarm cluster on my local machine, enabling me to deploy a function with faas-cli.

Good point .. glad you could figure it out. openfaas/faas@e40730f
