docker-up.sh does not work

[mquinson]

Hello there,

I wanted to test your neat project, but it fails to start here. My machine is a Debian box, 'testing' release. Here are the logs:

That's my very first run in this directory, so there is no previous state. As you can see, it downloaded all the images fresh. I get the very same error if I rerun the command.

Thanks for this very promising project,
Mt

Test that your local system supports docker correctly. Based on the error, it could be you are missing something related to cgroups. Debian sid includes that as it was already in previous stable release.

So, test that docker hello world works: https://hub.docker.com/_/hello-world/ . I.e. run docker run hello-world

You are right, the problem seems to be on my side. I'll fix it up and I come back afterward.

Sorry for the noise.
