Stack: Open-source scripts that build docker images

[k-bx]

Please, open-source (or point me to) your work on building docker images with full stack packages built inside, so that any person could reproduce and/or customize it.

[borsboom]

We're planning to open this, but the current tool contains some proprietary information and needs refactoring to make it possible to extract that and release the non-proprietary parts as open source.

@manny-fp thanks, good to know. We decided to search for less hardcode (in terms of infrastructure-change) ways for now, but I'll be watching this.

:+1:
I need a run minimal image alike stack-run but with ruby 2.x. I was hoping to get some information from the Dockerfile for stack-run but it is not available. I know it should be possible to install an extra ruby on the base image but I would prefer to have something as minimal as possible with a single ruby version (that rules out phusion as the base image).

If I understand it correctly, I will need to copy the binary executable for stack. I don't want ghc in the base run image.

Since the Docker integration can now use any image, custom images no longer need depend on the images FP Complete generates (see https://github.com/commercialhaskell/stack/blob/master/doc/docker_integration.md#custom-images). Therefore, reducing the priority of this issue.

You mean, the actual docker images are built after adding some changes (by the proprietary tools) to https://github.com/commercialhaskell/stack/blob/a562702b3bcda71bc73663320a38e7cb937d1163/etc/docker/stack-base/Dockerfile ?

How close is the linked dockerfile to the lts's?

[borsboom]

@kanishka-azimi: that Dockerfile is not related at all. I don't think that Dockerfile is actually used for anything and I'm going to remove it to avoid confusion.

BTW I'm planning to open this up in the very near future. We're moving away from the current shake- and propellor- based process to build the images to a simplified one without any of the proprietary stuff, so it will just be a simple Dockerfile.

The new scripts for LTS >= 8.0 are here: https://github.com/commercialhaskell/stack/tree/master/etc/dockerfiles/stack-build

This is vastly simplified from the proprietary scripts we were using for LTS <= 7.x. Now we're only building the stack-build images (no more stack-run and stack-full images), and a bunch of stuff is being left out as Stack itself has gotten the functionality built into it.
