OpenFaas is configured to run at http://localhost:8080
once vagrant up finish try:
faas-cli list

to connect to docker daemon in the vm faas1 use:
export DOCKER_HOST=tcp://localhost:2375

then run:
docker node ls

test it works:
curl -d "hello" http://localhost:8080/function/func_echoit
curl -d "" http://localhost:8080/function/nodeinfo

building a new faas:
cd playground
faas-cli template pull
faas-cli new --list
faas-cli new hello --lang=dockerfile
faas-cli build -f hello.yml
faas-cli deploy -f hello.yml

go to the webpage and play: http://localhost:8080
