In a meteor/docker deployment, where do you do your meteor build step?

I’ve seen lots of useful info on how to deploy an already bundled meteor app via meteord or phusion-passenger’s docker image etc etc.

But I haven’t found any examples of an automated deployment starting from a not-yet-bundled meteor app (say, on github), which include the meteor build step… any suggestions most welcome !

You can use meteord to create a image from that. Read the Meteord Readme.

Search this forum for docker, you will find more discussion. There is a detailed post on how to deploy a meteor app into opsworks using docker.
