Configure Google GKE for Cloud Agent Deployment

Configure cluster nodes for registry mirror (containerd)

A DaemonSet can be used to configure the GKE cluster nodes containerd runtime.

...

GKE nodes are automatically configured using the deprecated registry mirror format so the logic implemented in the DaemonSet should continuing this method.
The user may change the DamonSet logic to convert the configuration to the new format

Deploy DPOD Cloud Agent on k8s cluster using OLM

Starting k8s 1.25 Pod Security Admission became stable feature and adopted by most of the cloud providers which requires some configurations in order to deploy OLM and use it to deploy operators and applications. For further information see K8s documentation.

Change the DPOD Cloud Agent NS labels to conform with Pod Security Admission

Create the DPOD Cloud Agent CatalogSource in OLM NS

Based on OLM documentation in order to create subscription the CatalogSource should be created in the target NS (where the subscription for DPOD Cloud Agent is created) or in OLM NS (ClusterScope).

Use the following definition to create CatalogSource which conform with Pod Security Admission configured for the OLM NS:
