Cli: open ./template/python: no such file or directory error

[theodesp]

I'm trying to build a python example using the tutorial https://blog.alexellis.io/first-faas-python-function/ and the moment I call:

$ faas-cli -action build -f ./stack.yml

I get:

open ./template/python: no such file or directory error

is there anything that I miss?

Expected Behaviour

$ faas-cli -action build -f ./stack.yml
...

Successfully tagged faas-hello-python:latest  
Image: faas-hello-python built.  

Current Behaviour

➜  functions cat stack.yml
provider:
  name: faas
  gateway: http://localhost:8080

functions:
  hello-python:
    lang: python
    handler: ./hello-python
    image: faas-hello-python

➜  functions cat hello-python/handler.py
def handle(req):
    print("Hello! You said: " + req)
    %

➜  functions faas-cli -action build -f ./stack.yml
Building: hello-python.
Clearing temporary build folder: ./build/hello-python/
Preparing ./hello-python/ ./build/hello-python/function
2017/09/14 08:57:26 open ./template/python: no such file or directory

I was trying to follow the tutorial steps from here:

• Link to your project or a code example to reproduce issue:

@theodesp I was unable to reproduce, using the commands you had listed. There have been some updates to the cli recently though, what version are you using? faas-cli version

and you might also try running the below commands to see if you have better luck.

$ mkdir hello-python && cd hello-python
$ faas-cli new --lang python --name hello-python
$ faas-cli build -f ./hello-python.yml

@theodesp I managed to replicate but only through running the faas-cli command in the wrong place.

The blog post suggests using the user's home directory so the lay out of files should be:

~/functions
├── hello-python
│   └── handler.py
└── stack.yml

The faas-cli -action build -f ./stack.yml command from the blog should then be run from the functions directory.

Could you provide a directory listing of ~/functions after you have tried the build command? The templates should be being downloaded and unzipped to the working directory. The error above suggests that may not have happened.

As long as you don't have a template folder already, the templates are always downloaded every time you run a "build" or "new" command via the CLI.

[alexellis]

Here's an example:

$ faas-cli new --lang python --name test1
2017/09/14 12:28:40 No templates found in current directory.
2017/09/14 12:28:40 Attempting to expand templates from master.zip
Found "template/"
