Kubernetes集群最佳实践

Question

我正在使用Kubernetes进行新项目，我需要三个环境：DEV，QA和PROD。

最推荐的方法是创建多个群集，或者创建一个按名称空间分隔环境的大型群集。

Answer 1

Are you just going to have a single prod cluster or multiple prod clusters? One thing to consider is that updating the cluster management software (to a new k8s release) can impact your application. If you only plan to have a single prod cluster, I'd recommend running qa and dev separately so that you can upgrade those clusters first to shake out any issues. If you are going to have multiple prod clusters, then you can upgrade them one at a time to ensure application availability and sharing the clusters between environments makes a lot more sense.
