Even several deployment concerns (such as promotion between environments, secret handling, smoke testing) are conveniently left out of the GitOps paradigm, and teams that adopt GitOps need to create their deployments adopted by big organizations. The canonical example of mixing CI and CD is with smoke testing. Let’s say that you want to run some smoke tests AFTER a deployment has finished and the result run unit/integration tests. That would require visibility in the source code along with all the testing frameworks and libraries needed for the tests. This means that you are forced to use your CI solution

have small teams of developers work together to handle everything themselves—from building and testing to deploying. The move to DevOps requires technical and cultural changes at an organizational level for Platform Team assistance. The engineers focus on building container images and managing the testing of their microservices and Weave Flux handles the deployments.” The Platform Team wanted to leverage applied to the system. Choosing Weave Flux allowed their engineers to focus on building assets, testing them in specific environments while the software agent handled how those assets got deployed to

writing this book, I had the pleasure of learning alongside him, re- viewing his practices, and testing them directly in my setups along the way. Examining the strategies he created while helping to mature dev/staging/prod) with gating based on metrics for your CI/CD workflows. You can also integrate testing tools, do performance testing, chaos engineering, and more. Pulumi Kubernetes Operator The Pulumi Kubernetes

deployment yaml檔該如何部署 出多套環境給不同情境(e.g. dev, staging, testing, pre-prod, prod)嗎？ •如果各個環境有需要設定不同的參數呢？ •e.g. deployment名稱不同 (dev-api, staging- api, testing-api, pre-prod-api, Prod-api) 6 解決辦法? •寫5份deployment

GitOps allows users to manage infrastructure easily as a part of the overall DevOps process by testing and deploying changes quickly with the help of: CI/CD tools Automated deployments Shorter feedback application code with consistent: End-to-end workflows Standardized code structures Documentation Testing methods This introduces standardized and fully reproducible infrastructure configurations. Enhanced

modularity, independence, collaboration, versioning, and security. It allows for efficient development, testing, and deployment of both application and infrastructure components while ensuring clear separation
