Today we will take a look at the theory and practice of kubernetes and gitops Command introduction First, let’s take a look at the subnaming supported by kubectl for our convenience: kubectl apply - applies the definition of one or more resources. Typically used to deploy applications or update resources. kubectl get - displays information about one or more resources. This is a common command to view the status of resources in a Kubernetes cluster....

OpenIM offers various flexible deployment options to suit different environments and requirements. Here is a simplified and optimized description of these deployment options: Source Code Deployment: Regular Source Code Deployment: Deployment using the nohup method. This is a basic deployment method suitable for development and testing environments. For details, refer to the Regular Source Code Deployment Guide. Production-Level Deployment: Deployment using the system method, more suitable for production environments....

136: Hugo Advanced Coming to the advanced part, you need to learn some advanced Hugo techniques in depth. Module Hugo modules are the core building blocks of Hugo. A module can be your main project or a smaller module that provides one or more of the 7* component types defined in Hugo: **static**, **content**, **layouts**, **data**, **assets**, **i18n** and **archetypes**. You can combine modules in any combination you like, and you can even mount directories from non-Hugo projects to form a large virtual union file system....

Introduction About Kustomize GitHub Repository Get Started Kustomize is an open-source configuration management tool designed specifically for Kubernetes. It helps users customize Kubernetes objects and manage them declaratively without modifying the original YAML files. This means you can retain the basic settings for applications and components while overriding default settings with declarative YAML documents called “patches” without altering the original files. Kustomize provides a declarative approach that aligns with Kubernetes philosophy and allows customization of Kubernetes configurations in a reusable, fast, debuggable, and scalable manner....

Requirements OpenIM provides various public image registry addresses, such as aliyun, github, Docker Hub, and more. Read https://github.com/openimsdk/open-im-server/blob/main/docs/conversions/images.md for more image building guidelines. Most enterprises choose to set up their own image repository using Harbor, integrating it into their CI/CD pipeline to eventually replace Docker Hub and further reduce image storage costs. Additionally, in a production environment, Harbor generally enables TLS, so you will also need to prepare a valid domain name....

Automated testing practices and strategies for GitHub open source Go projects in the cloud native field introduce As OpenIM, a popular project on Github, how to create value in the cloud native era is very important. OpenIM is a small and high-quality team, and we do not have particularly in-depth insights in automation. Continuous Integration and Continuous Delivery (CI/CD) using GitHub Actions: GitHub Actions provides a platform to automatically build and test Go language projects....

Deep understanding of Kube-APIServer kube-apiserver is one of the most important core components of Kubernetes and mainly provides the following functions Provides REST API interface for cluster management, including authentication and authorization, data verification, cluster status changes, etc. Provides a hub for data interaction and communication between other modules (other modules query or modify data through API Server, only API Server directly operates etcd) apiserver main functions: Authentication: Use the cluster to determine identity....

And analyze ETCD in depth from the perspective of Kubernetes. Before starting ETCD is the hardest of all components in Kubernetes because ETCD is stateful, not stateless....

Introduction In the current module’s execution, numerous ports (ws, api, rpc, Prometheus) are passed directly. This approach can be cumbersome and doesn’t align with Kubernetes' best practices where a pod typically exposes only one port (either 80 or 443). This proposal suggests transitioning to a configuration file-centric approach, while still retaining the capability to pass ports directly when needed. Goals Simplify the port configuration for Kubernetes deployment. Prioritize port values passed as arguments over configuration file values....

Conference and Reference Links Conference reference documents: https://nsddd.notion.site/2899028707604b8090b36677c031cdf8?pvs=4 Video playback: Bilibili: https://www.bilibili.com/video/BV1s8411q7Um/?spm_id_from=333.999.0.0 Comment: I think that middleware can be replaced with https://kubeblocks.io which can help you manage multiple database middlewares. im reads the configuration information, and reads the config/ directory. The config.yaml hard-coded in the code can be automatically divided into rpc for different services, and then unified directories. By default, the directory is read from the binary running path....
