QUESTION
I've an existing deployment in my Kubernetes cluster. I want to read its deployment.yaml file from Kubernetes environment using fabric8 client.Functionality similar to this command - kubectl get deploy deploymentname -o yaml. Please help me to get its fabric8 Java client equivalent.
Objective : I want to get deployment.yaml for a resource and save it with me , perform some experiments in the Kubernetes environment and after the experiments done,I want to revert back to previous deployment. So I need to have deployment.yaml handy to roll back the operation. Please help.
Thanks, Sapna

QUESTION
I recently got started with building a Kubernetes operator. I'm using the Fabric8 Java Kubernetes Client but I think my question is more general and also applies to other programming languages and libraries.
When reading through blog posts, documentation or textbooks explaining the operator pattern, I found there seem to be two options to design an operator:
- Using an infinite reconcile loop, in which all corresponding Kubernetes objects are retrieved from the API and then some action is performed.
- Using informers, which are called whenever an observed Kubernetes resource changes.
However, I don't find any source discussion which option should be used in which case. Are there any best practices?
...ANSWER
Answered 2022-Jan-03 at 15:36You should use both.
When using informers, it's possible that the handler gets the events out of order or even not at all. The former means the handler needs to define and reconcile state - this approach is referred to as level-based, as opposed to edge-based. The latter means reconciliation needs to be triggered on a regular interval to account for that possibility.
The way controller-runtime does things, reconciliation is triggered by cluster events (using informers behind the scenes) related to the resources watched by the controller and on a timer. Also, by design, the event is not passed to the reconciler so that it is forced to define and act on a state.
QUESTION
How does one go about setting resource limits in EMR on EKS? My driver pod is failing to launch because it is requesting more CPU than it is allowed. This doesn't make sense to me. I am running the getting started code from the docs below.
I have added --conf spark.driver.limit.cores=2 in order to try and make the limit higher than what is listed in the error message below. I got this idea from here https://spark.apache.org/docs/latest/running-on-kubernetes.html#spark-properties
This cluster does have istio running in it. I am not sure if that would cause issues.
Here is the code I am running to trigger the job

Answered 2021-Nov-05 at 08:36From the code which you shared, it looks like you're using Fabric8 Kubernetes Mock Server in expectations mode. Expectations mode requires the user to set the REST API expectations. So the code shown below is setting some expectations from Mock Server viewpoint.

...ANSWER
Answered 2021-Oct-30 at 19:24It looks like you're using a version of the fabric8 client that is too old. You're using fabric8 5.3.0 while the quarkus-operator-sdk version 1.9.4 uses fabric8 5.4.0. Using the same fabric8 client version should solve your issue.

QUESTION
As we know, fabric can connect Kubernetes via ~/.kube/config file. I am wondering how to use farbric8 connects to connect to the Kubernetes API within a Pod? Is there any fabric8 API/library support it?
...ANSWER
Answered 2021-Oct-20 at 15:39I'm from Fabric8 team. Fabric8 Kubernetes Client automatically detects whether it's inside a Pod or outside.
When inside the cluster, Fabric8 Kubernetes Client reads Kubernetes API token and ceritificates from ServiceAccount mounted inside the Pod(
/var/run/secrets/kubernetes.io/serviceaccount/). Api server URL is determined by readingKUBERNETES_SERVICE_HOSTenvironment variable.When outside the cluster, it just reads
.kube/configas usual.
To end user, the process should be transparent. Just make sure your Pod's ServiceAccount has correct roles assigned to access some api group.
I had tested this some time ago on a demo project with minikube and it was working okay for me. You can try it out and see if it helps your use case: https://github.com/rohanKanojia/kubernetes-client-inside-pod
