Hi Adam,

Let's assume that you are building a service and you have to deploy it on bare metal servers using either of the below:

  1. Docker/Docker Swarm (no auto scaling feature out of the box)
  2. Kubernetes
  3. OKD/OpenShift

Since i would like to use the out of the box auto scaling feature i would choose the 2nd or 3rd option.

My question is : OKD/OpenShift puts another layer of abstraction on top of Kubernetes, does it worth using OKD/OpenShift with the extra layer/complexity?

Thank you.

Hi Adam,
First, thank you for the show and the podcast, really inspiring and great resources :)

Now the questions:

  1. I've created a Quarkus app and I'm using freemarker to template html frontend because I find it simple and easy to implement. Is it a good approach and how to secure my app for CSRF attacks and so on...? Or do I need to use javascript only and POST JSON?

  2. In your hibernate with panache video, the properties of the Workshop class are left public. Could you please explain why?

  3. I've used your enhydrator to do a poc for etl work. Would you still recommend it nowadays (now that nashorn has been deprecated) or would you recommend a new approach?

Thank you,
Guillaume

Hi Adam, looking at the specs in Microprofile (Config, OpenApi, Health Check, Metrics, etc.) , Do you recommend include and use them in a Monolithic Jakarta EE APP (single war)? Because If application server like payara, wildfly or tomee already includes them we can use it and keep our war thin. What are the benefits of this libraries in a monolithic app?

Tthank you.

Hi Adam,
We have completed all the microservices connection system with CDC and an Apache Kafka Cluster and its time to go production, do you think it's recommended to use OKD 3.11 instead of Openshift 3.11. If no what kind of alternative do you recommend in selfhosted in-premise environment.
Thanks

@mhrnr You can use Expression Language in order to get configuration value from a CDI bean. See an example: https://github.com/eclipse-ee4j/soteria/blob/master/test/app-custom-rememberme/src/main/java/org/glassfish/soteria/test/TestAuthenticationMechanism.java#L40

That's part of the spec and so is totally portable. A future version of the spec will probably add MicroProfile Config support.
