I already have a build server that I generate a docker image for an application with and then put it into cloud storage. This is not an image that can be publicly shared on the docker index. How can I run this application docker image in deis?
Deis is designed to build your docker image from your git repo via a buildpack or Dockerfile (although I can't find instructions on how to use a Dockerfile instead of a buildpack). This could be considered a legacy integration issue. However, the current setup of running the build service on the application cluster is not good for me, because I want my build server to be a lot more powerful than my application server. Ideally my build server would spin up on demand, although I don't bother with that rigt now.
We are hoping to resolve this feature request with https://github.com/deis/deis/issues/533.
Ideally we see it as "build your image with - insert CI product here - then run deis push --app=appname to deploy your docker image as an application". After that, it would be treated the same as any other application deployed to deis. Basically, deis push is to pushing docker images as git push is to pushing repositories.
In regards to documentation for deploying an application with a Dockerfile, the docs are at http://docs.deis.io/en/latest/developer/dockerfile/, though this workflow will change back to a more sane deployment workflow once https://github.com/deis/deis/pull/967 is merged. There was some technical debt from v0.8.0, and Dockerfile deployments was one of them.
