Hi,
thanks for sharing your use case.
By the way, we added Karaf Docker feature in Karaf 4.2.1 and we are
using Decanter on Docker Karaf "farm" to retrieve metric and log.
That's very convenient.
Regards
JB

We do run Karaf inside docker (using static assemblies).
The best thing I see in it is possibility to SSH into karaf and see
what's going on. This is especially useful when logs are not dumped to
stdout nor file but sent via network somewhere else. Log tail then shows
all events before they are serialized.
A nice side effect of SSH console is possibility to execute commands via
exec. ;-)) By this way you can browse basic file system contents and
verify files delivered via container/cloud orchestration tools.
Having said that we run static assemblies, I would like to note that we
do not rely on "dynamic" updates of configurations just yet. We
experiment with kube as new way to run things but we didn't reach yet
place where we deliver configurations from etcd. This is place which
will get really interesting. Most likely it will require us to go back
to traditional, non static, assembly in order to pick up updates pushed
via kube api.
We do have separate pipeline (with simple makefiles) for building docker
images which is detached from main build where we produce custom distro.
Its used to add cloud specific configurations.
In two projects where we didn't use a common configurations we had extra
profile in maven build for that.
Developer can run static assembly locally with minor inconvenience
caused by static configs. For local builds we also used docker-compose
which allowed to setup all required dependencies (such database).
Cheers,
Lukasz

I am currently looking into optimized ways to run OSGi applications in
the cloud.
I would like to describe how cloud native OSGi could look like.
Apart from my own experiments I would like to hear from other karaf
users. Do you run OSGi and especially karaf applications in the cloud?
How do you build your application? How do you do releases and
deployments? What do you do different compared to a non cloud setup.
Regards
Christian
