+# Table:  gcp_kubernetes_cluster
+
+A cluster is the foundation of Google Kubernetes Engine (GKE): the Kubernetes objects that represent the containerized applications all run on top of a cluster. In GKE, a cluster consists of at least one control plane and multiple worker machines called nodes.
+
+## Examples
+
+### Basic info
+
+```sql
+select
+  name,
+  location_type,
+  status,
+  cluster_ipv4_cidr,
+  max_pods_per_node,
+  current_node_count,
+  endpoint,
+  location
+from
+  gcp_kubernetes_cluster;
+```
+
+
+### List of all zonal clusters
+
+```sql
+select
+  name,
+  location_type
+from
+  gcp_kubernetes_cluster
+where
+  location_type = 'Zonal';
+```
+
+
+### List clusters where shielded nodes features are disabled
+
+```sql
+select
+  name,
+  location_type,
+  shielded_nodes_enabled
+from
+  gcp_kubernetes_cluster
+where
+  not shielded_nodes_enabled;
+```
+
+
+### List clusters where secrets in etcd are not encrypted
+
+```sql
+select
+  name,
+  database_encryption_state
+from
+  gcp_kubernetes_cluster
+where
+  database_encryption_state <> 'ENCRYPTED';
+```
+
+
+### Node configuration of clusters
+
+```sql
+select
+  name,
+  node_config ->> 'diskSizeGb' as disk_size_gb,
+  node_config ->> 'diskType' as disk_type,
+  node_config ->> 'imageType' as image_type,

+# Table: gcp_kubernetes_node_pool
+
+A node pool is a group of nodes within a cluster that all have the same configuration. Node pools use a NodeConfig specification. Each node in the pool has a Kubernetes node label, cloud.google.com/gke-nodepool , which has the node pool's name as its value.
+
+## Examples
+
+### Basic info
+
+```sql
+select
+  name,
+  cluster_name,
+  initial_node_count,
+  version,
+  status,
+  location
+from
+  gcp_kubernetes_node_pool;
+```
+
+### List configuration info of each node
+
+```sql
+select
+  name,
+  cluster_name,
+  config ->> 'diskSizeGb' as disk_size_gb,
+  config ->> 'diskType' as disk_type,
+  config ->> 'imageType' as image_type,
+  config ->> 'machineType' as machine_type,
+  config -> 'metadata' ->> 'disable-legacy-endpoints' as disable_legacy_endpoints,
+  config ->> 'serviceAccount' as machine_type,
+  config -> 'shieldedInstanceConfig' ->> 'enableIntegrityMonitoring' as enable_integrity_monitoring
+from
+  gcp_kubernetes_node_pool;
+```
+
+
+### List maximum pods for each node
+
+```sql
+select
+  name,
+  cluster_name,
+  max_pods_constraint ->> 'maxPodsPerNode' as max_mods_per_node
+from
+  gcp_kubernetes_node_pool;
