App Engine Flex: up-to-date hostnames of peer instances

[Dirk Louwers]

Hi,

I am currently trying to form a cluster with multiple GAE Flex instances. Therefore I expose the clustering port in the app.yml configuration. On instance start, an instance needs to be able to find it's peer instances in order to join the cluster. What is the best way to do this?

I have tried using Google Cloud Metadata instance data, but this only tells me something about the instance itself. Is there a way to achieve this using Google Cloud Metadata or would you recommend using something like Consul or etcd et al.?

Kind regards,

Dirk Louwers

Hello Dirk,

I don't believe there is a straightforward way to achieve what you're trying to do with App Engine as this is not the intended use case. Is there a specific reason you want to manually manage App Engine instances instead of using a Container Engine cluster?

Hi Yannick,

Yes I do. These specific instances need to be able to find one another in order to form a cluster. Was hoping this was possible now with App Engine Flex instead of going lower into the stack using Container Engine + Kubernetes API.

There is no built-in way to address specific App Engine flexible instances. What you can do is target specific App Engine standard instances but only if they are manually scaled.

Thanks, will look at Container Engine options.
