By the way, IMHO, it's also very convenient to take a running instance
(where users installed features, changed config) and create a image with
it. It's like the docker tag but from a Karaf perspective.
Like this, users can "prepare" different instance state and "store" in
docker image. That's the purpose of the Karaf docks.

What I've been working on those past days is a way to build docker images
based on a "static distribution" of karaf generated from profiles.
So starting from profiles, one can easily generate a docker image and push
it to a registry. The image would contain all the needed bundles and would
not have to be further "provisioned". I think this is more in line with
the "static container" idea which is the basis for docker.

Hi all,
In order to provide an alternative to the instances, I started to work on
a small PoC providing simple and convenient docker.io support in Karaf.
The purpose is to easily manage images, containers, and be able to
provision/create container with Karaf instances.
For instance, this is a current available use case:
1/ You can create a docker.io container in two ways:
1.1/ karaf@root()> docker:bootstrap mydock
creates a fresh docker.io container using karaf:3.0.3 image. I prepared
different ready to use docker.io images for Karaf. I'm working on an
embedded docker hub, with the appropriate commands to administrate it.
1.2/ karaf@root()> docker:provision mydock
creates a docker.io container (using a karaf image) and copy the current
running instance in the dock.
1.3/ It's also possible to start from a dockerfile.
2/ Once the dock (I named it dock meaning docker.io container where a
karaf instance is living) is ready, you can control it using docker:start,
docker:stop, docker:delete commands.
3/ it's possible to connect to a running dock using docker:connect command
I'm working on docker:image*, docker:hub, and improve the existing docker*
features.
However, before moving forward on this, I would like to know if it makes
sense and if people are interested by it.
By the way, the code is on my github: http://github.com/jbonofre/
karaf-docker.
I will push my last changes tomorrow morning.
Any comment is welcome.
Thanks,
Regards
JB
