With a ver 2 file works but with the same file in ver 3 I get;

$ kompose convert -f docker-compose.am-int.yml

@grebois can you paste your docker-compose file here ?

grebois · 2017-10-21T18:19:26Z

@surajnarwade can't really, too many secrets, will try to create one to reproduce the error. Just give me 2 days.

grebois · 2017-10-22T15:47:43Z

@surajnarwade here you can reproduce it;

      - 443:443
      - 80:80
    environment:

@grebois , kompose is behaving strict with environment variable, make sure you have already defined environment variables.

I tried following way,

export PASSWORD=xyz

and it worked,

]$ kompose convert -f docker-compose.yml  --stdout

But this only happens with version 3, version 2 works fine... try:

version: '2'
services:
  nginx:
    image: nginx
    ports:
      - 443:443
      - 80:80
    environment:
      - USERNAME
      - PASSWORD

cdrage · 2017-10-26T13:27:26Z

@grebois Thanks for the bug report. Yup. Version 3 should automatically pick up the environment variables. Looks to be an issue upstream. We'll investigate it and push out a fix!

@cdrage thanks!

Please guide me, how can I resolve this issue. your answer would be appreciated.

cdrage · 2017-12-14T15:11:25Z

@yogi-emorphis can you please post your docker-compose.yaml file?

yogi-emorphis · 2017-12-15T05:24:27Z

@cdrage Thanks for reply. I am not using docker, any other way for resolving ?

surajnarwade · 2017-12-15T09:01:49Z

@yogi-emorphis is this kompose related issue ?

yogi-emorphis · 2017-12-15T09:03:16Z

No , I am just trying to configure rinkeby.

surajnarwade · 2017-12-15T09:27:48Z

Probably this is wrong place to ask question regarding rinkeby.

yogi-emorphis · 2017-12-15T09:37:49Z

@surajnarwade May be you are right but I am facing same error. May be I will get any idea why are occurring this error.

cdrage · 2017-12-15T14:27:50Z

@yogi-emorphis rinkeby uses go-etherium, I'd suggest opening up an issue with your error here: https://github.com/ethereum/go-ethereum

@cdrage I think this should closed by #926 too.
