Taints allow you to mark nodes with specific restrictions, so pods will only be scheduled on them if they have corresponding tolerations.
Shared Kubernetes and Dedicated pool
Adding taints and configuring tolerations is needed.
If using a shared Kubernetes cluster with a dedicated user node pool, ensure that the user node pool has dedicated taints.
After creating taints, you must configure tolerations for Kyvos worker pods through Kyvos Manager in the kyvos-compute-worker-job.yaml.template file. This is applicable for all clouds (AWS, Azure and GCP).
...
If you do not have taints created for GCP, perform the steps mentioned below in this section to run Kyvos worker pods on a specific node pool.
You Ensure the user adding the taints must have the required IAM permissions to addtaints:
Editor or roles/container.admin or a custom role with sufficient permissions.
A separate Node pool is required to run system poolspods. Create a Node pool with the ‘n2-highmem’ configuration with Autoscaling disabled and count as 1.

Login to Kyvos Manager.
Navigate to the Utilities > Manage Configuration Files.
To configure taints as per your requirement, modify the kyvos-compute-worker-job.yaml.template file.
Download the kyvos-compute-worker-job.yaml.template file. In the kyvos-compute-worker-job.yaml.template file, you will find add the below section at the bottom of the file.
tolerations:
key: "key1"
operator: "Equal"
value: "value1"
effect: "NoSchedule"Copy the tolerations part and replace
Replace it in the kyvos-compute-worker-job.yaml.template file underthe KYVOSMANAGER_PATH/cloud/gcp/terraform/kyvos-k8s/ section.
