Learn how to build a Kubernetes Operator using the Operator-SDK. The Operator-SDK is an open-source toolkit that enables developers to create, test, and package Operators. It provides the scaffolding for building an Operator, simplifying creating and managing applications on Kubernetes.

Check out my courses on udemy:

As a learning operator-sdk, this example and demo is a good first step!

Great session, thanks for explaining!!!

[liorlew]

very good tutorial, especially because of the need of debug.

bhaiya this scaler is a resource type (like pods) in k8? coz i am not finding this in k8 docs, .

[VishalSaugat]

Hey @Aditya, is it possible to get the logs for custom resources provisioned ?

[asutoshpanda]

how to setup a server, then write crd for that server image, write operator for it and enable the mechanism such that even if you modify something in the manifests like adding some label or new upgrade etc then the pods shouldn't restart but the changes should be implemented?

Thank you very much. I am a beginner and it was very useful for me. In which case should we use kubebuilder and in which case operator-sdk?

[pranavsharma]

can you post some more cases on operators using operator sdk

[roopeshsaravanan]

Hi! I am getting this error when running the "mak run" command,

"ERROR unable to get kubeconfig {"error": "invalid configuration: no configuration has been provided, try setting KUBERNETES_MASTER environment variable", "errorCauses": [{"error": "no configuration has been provided, try setting KUBERNETES_MASTER environment variable"}]}"

I think the error is because that the program is running outside of the cluster. Any solution to resolve the error?

BTW, I am using Kubebuilder to build my operator.

Have you created the second part of this video? I meant deploying this operator to kubernetes cluster (Production)

[egfjren]

Hi, could you suggest whether we should use operator sdk or kubebuilder?

[kartik]

[pranavsharma]

Hi @Aditya want to ask you, With recent updated version the build is failing each time citing various packages and methods as reason, whats your advice which version should we use to make sure to build it successfully. However i want to stay updateed with newer versions but it seems there is no specific controller-runtime, go-client and other packages version that is stable. If you have any link to keep the versions stable you can share also. Please refer us to a stable package version as the newer ones are not that stable. Thank you
