Getting artefacts and dependencies into the container

[wouterd]

Have you tried the docker volumes approach?

• As in, put a VOLUMES '/path/to/webapps' in the docker file of the container.
• Create an image that only has an ssh server with a known key
• start that image with --rm and --volumes-from [containerid of first container] and scp into the folder.

Although I just prefer to rebuild SUTs and start those up, due to caching in docker that really isn't a huge deal, just have your SUT Dockerfile have only two lines: one FROM the base image and one ADD that adds the app.

I pretty much do most of this in my hippo-docker project. Check the two shell files under src/test/script.

Yes, caching might make this a no-issue (don't have much experience here). And no, I didn't try the scp approach yet. What I find interesting with the 'pure-artifact-image' approach is also that it nicely separates concerns: One image with the artifacts and one with the application server (without a concrete deployment), so that both could be used independently (e.g. with other app-servers for JEE apps or other artifacts). I thought about the scp-way, too, but then I wondered, why not using the Docker API for getting the artifacts via the REST API directly to an image.

But I'm still in brainstorming phase, so no hard opinions yet ;-)

I will look at you hippo-docker project for sure and maybe can give some feedback ;-]

Oops, thought I was on the other issue and didn't remember my ideas anymore ;-).

Currently my tendency are towars option (3) with the 'image-on-the-fly', but I think this is somewhat clear from my previous comments.

Need some time to get a better feeling, though.

Thanks a lot for you comments BTW ...

First implementation finished. It uses the maven assembly plugin as working horse and can create data container based on assembly descriptors, which are quite powerful with respect to mappings and inclusion of other dependencies.

A sample project has been added to illustrate the usage.

Still open: How to specify what should happen with the data image. Up to now the data containers gets removed, but not the image.

Removed the image as well. For using a different approach for getting data and image together, I'll open a new ticket.
