Cannot unmarshal float environment values.

[cdrage]

When passing in a float value through env: seems to fail:

Ex:

  environment:
    TEST: 4
    BAR: 0.3
    FOO: 0.3

ERRO Could not parse config for project foobar : Cannot unmarshal '0.3' of type float64 into a string value 
FATA Failed to load compose file: Cannot unmarshal '0.3' of type float64 into a string value

@cdrage , I was working on this issue, I found that, this error occurs due to libcompose, so I raised an issue docker/libcompose#435
(if you passed float value in quotes, it works)

Is this working with docker-compose ?

[surajnarwade]

@surajssd , yeah, it works with docker-compose but not with libcompose

[cdrage]

@surajnarwade As a work-around, should we update in our code to convert it to a string before being passed in?

[surajnarwade]

@cdrage , sounds good actually, I would like to work on it then

[surajnarwade]

@cdrage , I tried to work on this, this error occurs due to libcompose, hence as a work around, we can tell user that if you want to put float value, put it in quotes.

[cdrage]

@surajnarwade That wouldn't be a great work-around, our code should automatically detect that the environment variables are not in quotes and put them in converts / convert to string before passing to libcompose.

I did however take a quick look through the libcompose code and it doesn't seem too daunting to fix it upstream.

[surajnarwade]

@cdrage, I tested kompose with your PR on libcompose, docker/libcompose#437
its working.

Closing. Fixed in #425
