Hi guys,
let me "relaunch" this very old thread ;)
Even if most of us already use docker to run Karaf, I think that
karaf-docker could be a key and very interesting combination with
karaf-boot.
Imagine the following scenario:
- you construct your application thanks to karaf-boot (and the different
starters, karaf-boot-maven-plugin, etc)
- using your codebase, and the different starters that you use, the
karaf-boot-maven-plugin creates a Karaf custom distribution for you
- now, you can directly start your Karaf custom distribution on your
machines, your cloud, or docker: it's where karaf-docker can help.
In addition of the Karaf custom distribution, karaf-docker (and so the
karaf-docker-plugin that could be part of karaf-boot) can provide a
ready to run docker image with your custom Karaf distribution: you don't
have to prepare anything, the dockerfile, or whatever, it will be done
for you.
Of course, we keep the current features part of karaf-docker (the fact
to manage docker images directly in Karaf). I would like to add a new
set of features in karaf-docker: be able to create "business oriented"
Karaf (based on the first point). For instance, you want a Karaf
WebContainer, Karaf Hibernate, just use docker:create command to create
a custom Karaf distribution in a docker image, this distribution will
have "pre-installed/bootFeatures" as you described in the shell command.
Basically, karaf-boot and karaf-docker are in the same boat to provide
more user experience, flexible systems (profiles oriented) and killer
services platform.
I know that it's ambitious, but I trust in you all guys to help and
drive Karaf to a new dimension.
Thoughts ?
Regards
JB

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
