Creating a new function

1) create new function inside modules path

touch modules/mymodule/endpoints/myfunction.go

2) Add build instructions on Makefile

vim Makefile
build:
  dep ensure
  // ...
  env GOOS=linux go build -ldflags="-s -w" -o bin/mymodule/endpoints/myfunction modules/mymodule/endpoints/myfunction

3) Add function mapping on serverless.yml file

vim serverless.yml
# ...
functions:
  create:
    handler: bin/mymodule/endpoints/myfunction
    events:
      - http:
          path: /services/mypath
          method: get
    tags:
      TAGFUNCTION: Tag Value
