Is there a way to automatically update the type of a compute engine instance?

[Vinícius Fernandes]

Hi there,

I have a single g1-small machine running WordPress and I would like to know if there's a way to update it automatically to f1-micro using scripts or another GCP resource in predefined time ranges.

I want to do it to reduce costs in time ranges that I don't receive much traffic.

Regards,

Hello,

You can manually change the machine type of an instance [1], but only when it is stopped.

For an automatic update, here is a guide on how to do it but for a MIG [2]. It would work the same way as without the MIG. You can do so using instance templates and configure the automatic update the way you want it to be set up.

I hope this answers your question.
