Frustration-Free K8S for Spring Developers (SpringOne 2024)

Your first experience running a Spring app on Kubernetes likely left you wondering “How can I make this more efficient?” Just to get the app to run on Kubernetes, you likely had to: -Write a DockerFile to build a container -Upload that container to a registry -Construct multiple lengthy YAML files -Install a new CLI to apply those YAML files to the cluster -Cross your fingers and hope that you did everything right In this session, we show you a variety of tools and techniques that turn deployments to Kubernetes from a multi-step nightmare into every developer's dream: a single automated process that happens quickly and easily. You will leave this session no longer dreading deploying Spring apps to Kuberentes and instead making your deployments painless and intuitive, unlocking the true power of Kubernetes.

Amazing presentation. Learned so much 👏

Why Still Using RestTemplate ?

[@RyanBaxterJ]

@LoadBalanced only supports RestTemplate or WebClient at the moment. If you don't need the load balancer then you can use whatever HTTP client you would like.

[@neromadpro7228]

@@RyanBaxterJbut latest spring versions has new RestClient, any plans to support loadbalanced annotation for it?

[@zsiddiqi]

Ctlptl is supposed to be pronounced as “cattle patrol” as per the project docs :)

[@RyanBaxterJ]

Thanks! Yes, I always struggle to remember what it stands for.

Hi Ryan. Great presentation! Especially the parts around automating the non Java stuff. I have two questions: 1. Is there a GitHub repo with the sources? 2. Is Buildpacks able to crate arm containers? I briefly saw you’re using DaShaun’s builder, but I remember seeing somewhere that recently they’ve implemented that feature. Am I wrong?

[@RyanBaxterJ]

And as far as I know there is still no official buildpack support for arm, and DaShauns builder is the best option I know of

Very interesting. Does this play well with Spring Cloud Kubernetes? Are they complimentary?

[@RyanBaxterJ]

Yes it will. I use Spring Cloud Kubernetes in the demo 😊
