Hi Boris,
Your mail covers several points in fact:
1/ Artifact deployment
By artifact, I mean bundle, feature or kar.
Basically, you can the deploy folder using NFS to sync the bundle and
feature. The problem is that if you install a bundle or feature using
the shell, it won't be deployed on instances.
I think that the easiest way is a kind of script, connecting using ssh
and performing commands to replicate state.
Another solution is to "code" a kind of deployment client using JMX
layer of each karaf instances.
Finally, we're working on Apache ACE/Apache Kalumet/AutoDeploy to
provide a tooling for that.
The console lets you manage the configuration and artifacts. These
resources are "pushing" to an agent local to the Karaf instance.
2/ Karaf instances state sync
After the deployment phase, you should expect that your Karaf instances
are exactly in the same state (if a blueprint bundle is in GracePeriod
state, we expect the same state on others karaf instances).
We begun to deal with that yesterday, including maybe the usage of a
Karaf manager, etc.
This discussion is in KARAF-376:
https://issues.apache.org/jira/browse/KARAF-376
I hope it helps.
Regards
JB

Greetings, folks.
I'm looking for the solution for my failover requirements for bundles
run under Karaf 2.0.0. I would like to manage active and passive
instances of Karaf container.
My question is: what is the best way to perform deployment process on
several distributed Karaf container instances?
For example, I would like to install or update my software, how can I
achieve it for 2,3,4 container instances (nodes)?
There are several ways I find:
1. Use custom script with ssh, which will copy deployment archive in
auto deploy folder.
2. Mount autodeploy folder on each node to the same location by NFS.
3. Use feature url from mvn and build custom script, which do "refresh
url" for all instances.
Please, advice.
Could you please share best practice with me or point me to some success
stories with such use case.
Regards,
Boris Ilyushonak
