panic: runtime error: invalid memory address or nil pointer dereference

[beravelli]

I am facing this issue when converting the docker-compose.yml file . It is a straighforward compose file with couple of volume mounts and no env variables.

Kompose version : kompose version 0.1.0 (8227684)

Error:

Hi @beravelli
from trace you posted it looks like issue with libcompose, during parsing network definition.

Can you please show docker-compose file that you used, or at least snippet of it with network definitions?

[beravelli]

Hi kadel,

networks:
- incubator

networks:
incubator:

[beravelli]

It works when I take out the networks and volumes section in the docker-compose.yml file.

@beravelli network definition was improved with this recent PR #195. We will soon publish new release included this fix. Right now could you try getting kompose HEAD and test with your compose file?
