Learn About Automated Testing

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....

Design Proposal: Simplified Port Configuration via Config Files for Kubernetes Deployment

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....

OpenIM clustering design Kubernetes deploy concludes

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....

Cross Platform Compilation

Preface https://github.com/OpenIMSDK/Open-IM-Server/issues/432 Many places now have requirements for local adaptation of services. Generally, localized platforms provide an arm version of Linux cloud environment for us to deploy services, so it is necessary to build an arm version of the image. Build plan In the above issue, we describe the general construction ideas and solution steps. Let’s take a look at the construction plan. We take the most commonly used amd machine as an example to compile arm....
