How can I automatically temporarily disable synchronization for Terraform deployments managed by Flux (ToFu controller)?

Hi Team,

How can I automatically temporarily disable synchronization for Terraform deployments managed by Flux (ToFu controller)?

I want to disable the sync for my EKS cluster which is created by flux and then want to run the lambda to reduce the worker node during non business hours.

Any idea ?

You can use a pair of k8s CronJobs: one to resume the Terraform object at the beginning of the week, and one to suspend at the end.

Hi @matheuscscp

Can you share an example ? how to suspend ?

[matheuscscp]

See docs:

https://fluxcd.io/flux/cmd/flux_suspend/

https://fluxcd.io/flux/cmd/flux_resume/

There's one flux suspend and flux resume command for each Flux API.

In the k8s CronJob you need to use a k8s ServiceAccount that has the required permissions for manipulating the involved Flux objects.

You can use the image containing the flux CLI: https://fluxcd.io/flux/cmd/#install-using-docker

Or build an image yourself using e.g. https://fluxcd.io/flux/cmd/#install-using-bash
