Hitting issues using container

[altano]

Hey @solarkennedy thanks for this cool image.

I think I'm hitting the same issue as in /issues/2. I can use your image directly and it works:

PS C:\src\tradewars2002> docker run --rm -p 8080:8080 solarkennedy/wine-x11-novnc-docker

Navigate to this URL:

Press Ctrl-C to exit

But if I build your image from the Dockerfile and run it I get errors:

Not sure what the issue is. Any ideas?

[solarkennedy]

Exit code 127 usually means that the command is not found.

I don't "add" the code in a very good place (just /root/ so if you are putting something on top of that, it will blow away the novnc stuff.

[altano]

Here's what I did:

1. Clone this repo
2. Build: docker build --rm -t altano/wine-test:latest .
3. Run: docker run --rm -p 8080:8080 altano/wine-test:latest

And I get the same error above. Meanwhile your image works fine.

Does the repo in exactly its current form actually work for you?

[solarkennedy]

Can you show me the Dockerfile for altano/wine-test ?

[altano]

It’s the Dockerfile in this repo. I’m just building this repo. I was trying to do something custom before but now I’m just stuck getting this repo to work as is.

[solarkennedy]

I've confirmed that master as-is does work. I've just pushed a change that sends stderr to the console too, but I expect it to say "command not found" (127)

If you can, run the container with -ti and just run bash and see if you can run vnc directly and skip supervisord? I think that will give you the "smoking gun" https://github.com/solarkennedy/wine-x11-novnc-docker/blob/master/supervisord.conf#L19

[altano]

Yeah, that immediately revealed the problem.

It broke because I was using Windows to build the Docker image and the git repo was checked out with everything converted to CRLF. https://github.com/solarkennedy/wine-x11-novnc-docker/pull/4

Thanks so much!
