Docker build error

[StevenGann]

I'm pretty knew to Docker, so I'm not certain if this error message is significant or not. I do know that I can't get the system to work correctly (no errors or issues with the VISIONAI version).

docker build -t hamstah/deepdream-compute .

Looks like when you're downloading google-glog, you're trying to download from the defunct Google Code site. It's been moved to Github.

Investigating a fix.

Okay, it turns out the failure to download google-glog was stopping the whole docker build process. Updating the URL for downloading it help, though it still doesn't seem to be working and google-glog throws a compile error:

Sounds like a warning, but thought I'd document it anyway. It's the only highlighted error.

Looks like Cython is having trouble installing, specifically scikit.

Continuing investigation.

Cython now installs correctly, and everything compiles/builds successfully.

Unfortunately, there's still no web server accessible.

Hey Steven. Could you send a PR for the fix for the build step?

How did you start the services? What is the output of docker ps, do you have nginx running in there?

The issue could be that you already have a server running on the port used by the nginx container, see below for an example error message. "ERROR: for nginx driver failed programming external connectivity on endpoint clouddream_nginx_1 (378c34bc15828a7ed44b475c73b56c9d718d36b422e01036c16e72b66858c32e): Error starting userland proxy: listen tcp 0.0.0.0:80: bind: address already in use"

You can just edit the docker compose file to bind the nginx port to a different one, for example

nginx:
  image: nginx
  volumes:
    - ./deepdream:/opt/deepdream
    - ./deepdream/nginx.conf:/etc/nginx/nginx.conf
  links:
    - manager
  ports:
    - 8080:80

Hope this helps, sorry for the delay getting back to you

I'll definitely make a PR once I get it actually working.

How did you start the services?

The provided start.sh script.

What is the output of docker ps, do you have nginx running in there?

deepdream-nginx is present. I can't give you a full output because I had to clear everything out to change systems. I'll be starting fresh on a faster computer.

I'll try your suggestion for changing the port, but the instructions said to have Apache2 running. I'm not familiar with Nginx, but I did think it was odd to have two HTTP servers running at the same time.
