Describe the feature or resource

Since Backup for GKE became GA, there would be nice to manage resources via Config Connector.

Essentially, this support may be useful for applications that have specific needs, so while deploying an application on GKE the deployment could carry its own app custom backup config.

As an example, a TIER_1 application having its own backup plan may have multiple backups a day, while a TIER_2 application would have a single backup a day.

Couple of use cases:

Based on the product documentation, there are a couple of use cases that this support would be helpful. For instance:

• You want to store your backup artifacts in multiple regions. In this case, create a backup plan for each region in which you want to store backups.
• You want to partition the backups of your cluster, for example:
  • Instead of one very large backup taken at a single time of the day, you want multiple smaller backups distributed throughout the day.
  • You want to back up some portions of your cluster more often than others (such as daily backups for some namespaces and hourly backups for others).
• You are managing your cluster backups via Terraform[1][2][3] and deploying your workloads on GKE using a CICD tooling (e.g Google Cloud build, Gitlab-ci, etc...), once you onboard a new application using the CICD tooling, you may also need to apply the Terraform code to include the onboarded application.

Hi @Jeskz0rd , thank you for the request and all the details. Looks like the resource you want Config Connector to support is GKEBackupBackupPlan, right?

If it is important or time sensitive to your project, please reach out to us via Cloud support to prioritize the request.

@maqiuyujoyce that resource looks like the right one, but when installing config connector it is not part of the installed CRDs. We have installed 1.112.0 from gs://configconnector-operator/latest/release-bundle.tar.gz

[diviner524]

It is supported as one of our v1alpha1 (preview) CRDs.
