Conditional Features startup in karaf

[imranrazakhan]

We have karaf in Openshift and sharing central configuration through
configmap. We have to start/stop or make available features/bundles on base
of central configuration.

So if central configuration tag one bundle as enable we will start it or if
central configuration tag feature as disable we should stop that bundle.

Do karaf support some API to control bundle lifecyle on base of external
configuration.

sometimes we have to deploy karaf in active/passive but without availability
of shared filesystem in datacenter or database for locking.

we develop custom socket based lock system for karaf but it only work for
two servers. After searching lot we find one solution GlusterFS.

Hi Jean,

As you highlighted "having all in one config is possible, but it gives less

term of update/reload" 

Any idea to implement placeholders like below in feature.xml by this we have

how to override configuration of feature in KarafTestSupport

[imranrazakhan]

I am testing deployment of my feature.xml

 

prop1 = 60
prop2 = 60



I am testing with pax-exam and i want that before deployment of feature i
could able to change properties value, i tried couple of options but not
working as per expectation

1- i change values in feature.xml, but i dont want to change it as i am
pulling it from central place so may effect others testing.

2- executeCommand("config:property-set prop1 1\n" + "config:update", new
RolePrincipal("manager"));
But before it feature already started with defaults values and which is not
required.

I think ideal option would be if i could change on below line

   

KarafDistributionOption.features(CoreOptions.maven().groupId("com.my.features.base").artifactId("my-core").type("xml").classifier("features").version("2.1.1"),
"my-base-configuration"));

can't cast to implemented interface in Test with KarafTestSupport

[imranrazakhan]

I am doing integration test but getting error in which i can't cast to
implemented interface

IPOJO Component:
@Component(immediate = true)
@Provides
public class MyComponent implements MyService
{

@Override
public boolean islock()
{
return true;
}

}

Following is test class extending KarafTestSupport

@Test
public void serviceCreationIsWorking() throws Exception
{
assertBundleInstalled("com.my.osgi.mycomponent");

MyService serviceObject = getOsgiService(MyService.class, 3l);
System.out.println("getOsgiService=" + serviceObject);
System.out.println("getOsgiService method=" +
serviceObject.islock());
assertConditions(5000, "No deadlock detected!", () ->
serviceObject.islock() == true);
}

But on following line it throws error 

java.lang.ClassCastException: com.my.osgi.MyComponent cannot be cast to
com.my.osgi.MyService

MyService serviceObject = getOsgiService(MyService.class, 3l);

I googled and i found that

/This can happen if two different classloaders load a class named
.

These two classes are then treated as entirely different classes, even if
they have the same package and name (and even
implementation/fields/methods).

A common cause for this is if you use some kind of plugin system and both
your base classes and the plugin classes provide the same class./

Any suggestion to resolve class loader issue??

Deployment difference between karaf feature bundle and karaf bundle:install

[imranrazakhan]

How below both deployments are different


mvn:com.my.osgi/mycomponent/0.0.1


and

bundle:install -s mvn:com.my.osgi/mycomponent/0.0.1

what i observed is deploying with feature shows service:list like

[com.my.osgi.mycomponent]
-
instance.name = mycomponent.3c2c91a5-4c28-46c3-a08e-1470192ef353
 service.bundleid = 76
 service.factoryPid = com.my.osgi.mycomponent
 service.id = 397
 service.pid =
com.my.osgi.mycomponent.3c2c91a5-4c28-46c3-a08e-1470192ef353
 service.scope = bundle

and by deploying with bundle:install

[org.apache.felix.ipojo.Factory]

 component.class = com.my.osgi.mycomponent
 component.description = factory name="com.my.osgi.mycomponent"
bundle="77" state="valid" implementation-class="com.my.osgi.mycomponent"
requiredhandlers list="[org.apache.felix.ipojo:properties,
org.apache.felix.ipojo:callback, org.apache.felix.ipojo:provides,
org.apache.felix.ipojo:architect
ure]"
missinghandlers list="[]"
provides specification="com.my.osgi.mycomponent"
inherited interfaces="[com.my.osgi.mycomponent]"
superclasses="[]"
 component.providedServiceSpecifications = [com.my.osgi.mycomponent]
 factory.name = com.my.osgi.mycomponent
 factory.state = 1
 service.bundleid = 77
 service.id = 153
 service.pid = com.my.osgi.mycomponent
 service.scope = singleton

it work fine but my pax-exam tests are getting failed as after installing i
look for service

serviceReferences =
this.bundleContext.getServiceReferences("com.my.osgi.mycomponent", filter);

how i should deploy in pax-exam so i can access services like feature
deployments?

Socket based locking in karaf

Do socket based locking can be implement for karaf rather than file or DB. As
i only have two instance so each node would act as socker server/client. No
third dependency would require.

is this good idea? or recommend any alternative apart from file and DB i
want to implement this in docker swarm cluster.

Migration karaf from Legacy deployment to cloud

[imranrazakhan]

Currently we have karaf deployment like following

1- Its active-standby
2- Standby is there with startlevel as 50 so failover would be fast
3- As soon as active goes down standby takeover.

Now we planned to migrate to kubernetes, as per current research

Kubernetes will create 1 pod for us and we declare happy state as 1 which
mean if POD goes down it will automatically launch new, but my concern is
launching of new POD will take more time as in legacy deployment, standby
was in semi active state.

How we can achieve such active-standby in kubernetes?

Re: Failover with Apache Karaf + Cellar + Docker

[imranrazakhan]

Ok i will look into it.

As of now i dont have NFS, so will try to use HOST file system for locking.

Re: Failover with Apache Karaf + Cellar + Docker

[imranrazakhan]

Ok, thanks for updates.

Please provide details how we can achieve failover behavior(A 'hot' standby
instance) like mentioned in 

   
https://svn.apache.org/repos/asf/karaf/site/production/manual/latest-3.0.x/failover.html
 

in Docker environment?

How karaf support to communicate between two images/pods. 

As we can use kubernetes for orchestration of instances but i am not clear
how to achieve "A 'hot' standby instance" with it. Kubernetes will start and
stop bundles regardless of statuses of bundles of karaf pods

Failover with Apache Karaf + Cellar + Docker

[imranrazakhan]

Hi,

I have two karaf instances with Active-Passive configurations. Following is
deployment details

1- One become master and all bundles are with start status.
2-  Second instance is also up but all my developed bundles are with install
status but not running.
3- Both instance communicate on socket and as soon as first goes down second
instance just change the status of bundles from install to status, due to
which uptime in failover is very minimum.
4- these bundles dont expose http services so i cant use load balancer.

I was evaluating Apache Cellar and found i can achieve same behavior with it
by setting karaf.lock.level=50 property in etc/startup.properties.

But i want to deploy both instances with docker images and locking is only
done through filesystem or DB.

How Cellar support locking in cloud environment? Please point some blog or
documentations to achieve this behavior in .

What are Best Practices for Karaf based application Integration Test with Pax-Exam

[imranrazakhan]

We have lot of integration tests for our karaf based applications, so now
discussion got started

 - Should these itests done by developer or devops, as it took too much time
and developer has to wait?

 - Do itests part of project or we should have separate project?

 - if its separate project then do these got trigger after developer commit
code?

 - As developer says in case of any error in ITESTs it would be
configuration issue  and no code changes as code tests done with junit.

 - How can jenkin and PaxExam support in this regard?

Re: Karaf Cellar sync issue and NullPointerException

[imranrazakhan]

Hi,

I tried cluster-sync with other camel feature and behavior was same.

cluster:feature-install is working as expected.

Can you please elaborate about below statement with example ?

"/cluster-sync is not required, it's only used when you have a split brain/"

Regards,

Karaf Cellar sync issue and NullPointerException

[imranrazakhan]

I am new to cellar and trying to do POC, I did following steps

 - Install Karaf(4.1.5) on two instances.
 - feature:repo-add
mvn:org.apache.karaf.cellar/apache-karaf-cellar/4.1.1/xml/features (On both
instances)
 - feature:install cellar (On both instances)
 - Edit hazelcast.xml on both instances and set following section (On both
instances)

> 
> 10.10.10.11
> 10.10.10.12
> 

 - When i check cluster status(cluster:node-list) following is output

 

│Id  │Alias│Host Name  │Port

┼┼─┼───┼

│10.10.10.12:5701│ │10.10.10.12│5701

│10.10.10.11:5701│ │10.10.10.11│5701

As auto sync is not enabled i installed camel-scr bundle on one instance and
on running cluster-sync i am getting below error and now it also removing
some features and camel-scr goes back to uninstall state
