MicroProfile Health, FaultTolerance, Config and Metrics implemented in KumuluzEE

[Matjaz B. Juric]

Hello,

Just wanted to let you know that in KumuluzEE we have implemented (in addition to MicroProfile 1.1) also the MicroProfile Health 1.0, Fault Tolerance 1.0 and Config 1.1. You can have a look here:
-    Health: https://github.com/kumuluz/kumuluzee-health
-    Fault tolerance: https://github.com/kumuluz/kumuluzee-fault-tolerance
-    Config: https://github.com/kumuluz/kumuluzee-config-mp

We also have Metrics implemented, but the implementation is not yet fully compliant with MP Metrics 1.0 (we are working on it): https://github.com/kumuluz/kumuluzee-metrics

Samples are available here:
https://github.com/kumuluz/kumuluzee-samples/tree/master/kumuluzee-health
https://github.com/kumuluz/kumuluzee-samples/tree/master/kumuluzee-fault-tolerance-hystrix
https://github.com/kumuluz/kumuluzee-samples/tree/master/kumuluzee-config-mp
https://github.com/kumuluz/kumuluzee-samples/tree/master/kumuluzee-metrics

Here is a tutorial on how to develop a cloud-native Java EE microservice application:
https://github.com/kumuluz/kumuluzee-samples/tree/master/tutorial-microservice-config-discovery-faulttolerance-logs-metrics-security

Please feel free to use the samples for any demonstration or session if you wish to demonstrate these MicroProfile features.

For any questions, please do not hesitate to contact me.

Best regards,
Matjaz

Nice. You are working on an MP-JWT 1.0 feature as well correct?

[Matjaz B. Juric]

Yes, we are, but we need a few more days to finish it.

Best regards,

Matjaz

Wow, great to hear.

[Emily Jiang]

wow... Congratulation!!

Do you plan to update the MicroProfile conference app to demonstrate the features in J1?

Emily

[Matjaz B. Juric]

Thanks for mentioning. We can prepare Schedule and Speaker microservices for the demonstration.

Where will this demonstration at J1 take place and how can we participate? Will this take place at the Microprofile booth?  Will there be a session on the conference?

Thanks,

Matjaz

[Emily Jiang]

Good questions. I think individual vendors can demo the conference app in their booth. I don't think there is a session on the conference app.

We have added KumuluzEE implementations of the Schedule and the Speaker microservices. Both services have Health (/health endpoint), Metrics (/metrics) and Config included and implemented. For Metrics, there is also a Prometheus exporter accessible on /prometheus (which is a nice addition for the demo).

As I just wrote on the PR:

The MP-Metrics /metrics should respond with Prometheus text data if nothing else is requested, so how is /prometheus different here?

With the rush to JavaOne this got by me. Congrats!!

Is there a (pre-built) version of this available for download somewhere?

[Matjaz B. Juric]

You can download the Uber-JARs from here: https://www.dropbox.com/sh/eqzufcle3zc6z3w/AACyx-UxIIMGikD7o1mIzN8ca?dl=0

However, you simply go into the subdirectory and then use mvn clean package to build the JARs.

Hope this helps. Best regards,

Ah, I was very unclear - I meant the server itself so that I can deploy an application of mine.

The background is that I want to showcase this at EclipseCon Europe

[Matjaz B. Juric]

Hi Heiko,
I'm still not sure if I understand the question. KumuluzEE does not require a server. Everything, including the runtime is packed into the JAR (Uber JAR). You only need JRE to execute such Java EE microservice (Uber JAR). For example: java -jar microservice-schedule-kumuluzee.jar

To develop and build a KumuluzEE microservice you also only required IDE and Maven – and then you add the required dependencies, as mentioned here:
https://github.com/kumuluz/kumuluzee/blob/master/README.md
Tutorials and samples are here: https://ee.kumuluz.com/tutorial

We can help you with the preparation and would appreciate it very much if you do a showcase at EclipseCon Europe.
Please let me know. Thanks,
Matjaz

Matjaz, has KumulezEE passed all the relevant TCKs?

[Matjaz B. Juric]

Hi John,
For the specs which we fully support, yes (config, health, fault tolerance). Metrics are not yet fully compliant.
Best regards,
Matjaz
