- Java Kubernetes and Java: Leading the new trend in the cloud-native era
- Java has always been a popular choice for enterprise software development, and its stability, maturity, and rich ecosystem of libraries and frameworks make it ideal for building high-performance, scalable applications. As a container orchestration and management system, Kubernetes provides a unified platform to deploy, manage and expand containerized applications. The combination of Java and Kubernetes brings new opportunities and advantages to cloud native development. 1. Embrace cloud native architecture Cloud native architecture is a software development method based on containers, microservices and devops practices. It emphasizes application portability, scalability, and elasticity. Java and Kubernetes are two key technologies for cloud native architecture. Java as a general purpose programming

- The future of PHP microservices architecture: trends, innovations and best practices
- Microservices architecture has become a popular approach to building modern, scalable, and maintainable web applications. As a mature programming language, PHP is widely used in microservice development. This article will explore the future of PHP microservice architecture, introduce the latest trends, innovative technologies, and best practices to help you build high-performance, scalable distributed systems. Trend 1. Serverless computing: Serverless computing platforms such as AWS Lambda and Azure Functions automatically manage infrastructure, allowing developers to focus on writing code. This reduces operational costs and improves scalability. 2.Docker and Kubernetes: Docker can be used to package and deploy microservices, while kub

- Teach you how to build a K8S cluster.
- Building a Kubernetes (K8S) cluster usually involves multiple steps and component configurations. The following is a brief guide to setting up a Kubernetes cluster: Prepare the environment: at least two server nodes running the Linux operating system, these nodes will be used to build the cluster. These nodes can be physical servers or virtual machines. Ensure network connectivity between all nodes and that they can reach each other. Install Docker: Install Docker on each node to be able to run containers on the node. You can use corresponding package management tools (such as apt, yum) to install Docker according to different Linux distributions. Install Kubernetes components: Install Kuber on each node

- Master the importance and practical skills of Linux processes and threads
- As a Linux system administrator, it is very important to understand and master the concepts of processes and threads and the corresponding practical skills. This not only helps us better manage system resources, but also improves the operating efficiency and stability of the system. This article will give you an in-depth understanding of Linux processes and threads, and share some practical tips and tools. A process is a running activity of a program with certain independent functions on a certain data collection. It is the basic unit of dynamic execution of the operating system. In traditional operating systems, the process is both the basic allocation unit and the basic execution unit.

- golang error 'object has been modified' on k8s operator
- "Object has been modified" error occurs on k8s operator import "sigs.k8s.io/controller-runtime" There is a lot of discussion about this error. The main answer is "This problem occurs because I have an old version of the object when I try to update." But I also have some questions. In my operator, for some scenarios, I need to update a pod's annotation 2 times during one "coordinate" call. Of course I often get the "object has been modified" error. Question: I want to know where 'r.Get()' and 'r.Update()' get/update objects? From local cache, or API server? 1:I think 'r.Ge

- Top 10 Linux Server Distros of 2023
- Due to its various advantages, the Linux operating system is a popular choice among all types of servers. First, it is free (except for a few commercial distributions, such as RHEL and SLES) and open source. Its open source nature means that developers can view its source code and make modifications, and it can be redistributed under specified license terms. Secondly, Linux is generally considered stable, versatile, and more secure than Windows. Finally, Linux can be easily deployed on various platforms, such as bare metal, virtual machines and cloud environments. In this article, we highlight the top 10 Linux server distributions. 1.

- How does gRPC know the service IP address of a microservice?
- I started with Google Cloud Platform's microservices demo. I'm curious how grpc stubs work when the service is deployed in a container. From what I understand, the container for a specific service is addressed by the service ip specified in the yaml configuration file. So does the grpc server of the service have to listen to the service IP? But I encountered the following code snippet: l,err:=net.Listen("tcp",fmt.Sprintf(":%s",port))iferr!=nil{log.Fatal(err)} I want to know about the server How to monitor an address without ip?

- Update status of custom Kubernetes controller in golang

I've tried: update the whole resource: ifr=r.client.update(ctx,upcrd);err!=nil{returnctrl.result{},client.ignorenotfound(err)} and update only the status: ifr=r.status ().update(ctx,upcrd);err!=ni

- Equivalent to 'kubectl get crds' in golang
- If I want to list the namespaces on the cluster using client-go, I can do this with a simple command: clientset.CoreV1().Namespaces().List(context.TODO(),metav1.ListOptions{} ) What is the equivalent command to the kubectlgetcrd command? is it possible? I tried to find a solution but most of the answers I found answered how to query for specific crds rather than getting a list of them.

- Remove metric unable to run kubernetes operator controller
- I've been working on my operator in which I have some custom indicator setting values and it works fine (registering and displaying indicator values). The problem is that indicator deletion is not happening. I tried to declare a separate function to remove the indicator. My operator is starting stateful sets and services, but after deleting my cr, the subresources are deleted but the metrics don't get any updates/removals. func(r*cr)reconcile(ctxcontext.context,reqctrl.request)(ctrl.result,error){............iferrors.isnotfound(

- Convert dot-separated values to Go struct using Python
- This is a specific requirement for applications where the configuration can be changed (especially wso2identityserver, since I'm writing a kubernetes operator for it using go). But it's really not relevant here. I want to create a solution that allows easy management of large number of configuration maps to generate go structures. These config maps are linked in .csv to .csv-my_configs.csv I want, to write a python script that automatically generates go structures so that any changes to the application configuration can be created by simply executing the python script to create the corresponding go structure to update. I'm referring to the configuration of the application itself. example
