This is awesome, I need to check this out in detail. Do you have good elastic beanstalk integration?

What does "good" integration mean to you?

That is, we have elastic beanstalk support, but I'd love to know how we can make it better :)

there is an elastic beanstalk example in the docs http://circlehost:8080/docs/docker#elastic-beanstalk

Might wanna update that url :P.

oops! thanks for the heads up https://circleci.com/docs/docker#elastic-beanstalk

How well is the caching supported. Is there a way for me to cache and restore my gem dirs?

CircleCI has great caching support for gems, etc (we've had this for about 2 years, so it's really mature). I suspect it might need to be tweaked to support docker use cases a bit better, so can you try it out and let us know?

Gem caching in docker is more about layer construction than anything the CI would do as such.

Though old: http://ilikestuffblog.com/2014/01/06/how-to-skip-bundle-inst...

This doesn't work in a CI between multiple machines.

See the discussion around this in drone https://github.com/drone/drone/issues/147

can you run privileged containers (so that you can run tests that use docker internally?)

Yes, I believe so, but not enabled by default. Can you contact [email protected] with your use case and we can figure it out?

thanks just mailed
