GKE从默认迁移到共享VPC，从公共迁移到私有GKE集群 [英] Migration of GKE from Default to Shared VPC and Public to Private GKE CLuster

问题描述

关于GKE的查询很少

• 我们在Default VPC上运行的GKE个集群很少.我们可以迁移这些集群以使用SharedVPC或至少Custom VPC吗?根据GCP文档，似乎默认VPC模式下的现有群集无法更改为SharedVPC model，但是我们可以从default VPC
转换为Custom VPC
• 如何从Custom VPC迁移到Shared VPC?是否会从现有集群创建一个新集群，并在网络部分中为新集群选择SharedVPC，然后将Kubernetes资源复制到新集群?
• 看起来我们也无法将public GKE群集转换为private模式.这是否还需要创建新的集群才能从Public迁移到Private GKE集群?

• We have few GKE CLusters running on Default VPC. Can we migrate these clusters to use SharedVPC or atleast Custom VPC? It seems existing clusters with default VPC mode cannot be changed to SharedVPC model as per GCP documentation but can we convert to Custom VPC from default VPC
• How to migrate from Custom VPC to Shared VPC? Is it creating a new Cluster from existing Cluster and select SharedVPC in networking section for new cluster and then copy the Kubernetes resources to new Cluster?
• Also looks like we cannot convert public GKE Cluster to private mode. Does this too requires creation of new Cluster to migrate from Public to Private GKE Cluster?

推荐答案

不幸的是，您无法在现有 GKE 群集上更改任何这些设置.您可以使用群集详细信息中的DUPLICATE选项卡克隆现有的计算机:

Unfortunatelly you cannot change any of those settings on the existing GKE cluster. You can clone the existing one by using DUPLICATE tab in cluster details:

在创建新集群期间，可以在Cluster -> Networking部分中将其从Public更改为Private:

During new cluster creation you can change it from Public to Private in Cluster -> Networking section:

选择后，您需要更正标记为红色的字段:

After choosing it you'll need to correct fields that are marked in red:

您还可以选择其他VPC网络.

You can also choose different VPC network.

在迁移工作负载时，这是另外一回事了.您可以选择最适合您的方法，从手动导出所有yaml清单(我会说非常繁琐且不太方便的过程)到使用

When it comes to migrating a workload this is separate story. You can choose the approach which is most suitable for you, ranging from manually exporting all your yaml manifests (pretty tedious and not very convenient process I would say) to using dedicated tools like velero.
