如何更改 AWS ECS 集群中的实例类型? [英] How to change instance type in AWS ECS cluster?
问题描述
我在 AWS EC2 Container Service 中有一个集群.当我设置它时，我使用了 t2.micro 实例，因为它们足以进行开发.现在我想使用更强大的实例，比如 m4.large.
I have a cluster in AWS EC2 Container Service. When I've set it up, I used t2.micro instances because those were sufficient for development. Now I'd like to use more powerful instances, like m4.large.
我想知道是否可以只更改实例类型，所以我不需要重新创建整个集群.我找不到如何执行此操作.
I would like to know whether it is possible to change the instance types only, so I don't need to recreate the whole cluster. I could not find how to do this.
推荐答案
是的，这是可能的.
集群中的实例类型由启动配置中的实例类型"设置决定.无需重新创建集群即可更新实例类型:
The instance types in your cluster are determined by the 'Instance Type' setting within your Launch Configuration. To update the instance type without having to recreate the cluster:
- 复制集群启动配置并更新实例类型".
- 调整集群Auto Scaling Group以指向您的新启动配置.
- 等待您的新实例在您的集群中注册并启动您的服务.
- Make a copy of the cluster Launch Configuration and update the 'Instance Type'.
- Adjust the cluster Auto Scaling Group to point to your new Launch Configuration.
- Wait for your new instances to register in your cluster and your services to start.
您还可以通过创建链接到不同启动配置的多个 Auto Scaling 组，将多个实例类型添加到单个集群.但请注意，您无法在控制台中轻松复制 Auto Scaling 组.
You can also add multiple instances types to a single cluster by creating multiple Auto Scaling Groups linked to different Launch Configurations. Note however that you can't copy Auto Scaling Groups easily within the console.
