class Google::Apis::ContainerV1::NodePool
NodePool
contains the name and configuration for a cluster's node pool. Node pools are a set of nodes (i.e. VM's), with a common configuration and specification, under the control of the cluster master. They may have a set of Kubernetes labels applied to them, which may be used to reference them during pod scheduling. They may also be resized up or down, to accommodate the workload.
Attributes
NodePoolAutoscaling
contains information required by cluster autoscaler to adjust the size of the node pool to the current cluster usage. Corresponds to the JSON property `autoscaling` @return [Google::Apis::ContainerV1::NodePoolAutoscaling]
Which conditions caused the current node pool state. Corresponds to the JSON property `conditions` @return [Array<Google::Apis::ContainerV1::StatusCondition>]
Parameters that describe the nodes in a cluster. Corresponds to the JSON property `config` @return [Google::Apis::ContainerV1::NodeConfig]
The initial node count for the pool. You must ensure that your Compute Engine [ resource quota](cloud.google.com/compute/quotas) is sufficient for this number of instances. You must also have available firewall and routes quota. Corresponds to the JSON property `initialNodeCount` @return [Fixnum]
- Output only
-
The resource URLs of the [managed instance groups](cloud.
google.com/compute/docs/instance-groups/creating-groups-of-managed-instances) associated with this node pool. Corresponds to the JSON property `instanceGroupUrls` @return [Array<String>]
The list of Google
Compute Engine [zones](cloud.google.com/compute/ docs/zones#available) in which the NodePool's nodes should be located. If this value is unspecified during node pool creation, the [Cluster.Locations](https:/ /cloud.google.com/kubernetes-engine/docs/reference/rest/v1/projects.locations. clusters#Cluster.FIELDS.locations) value will be used, instead. Warning: changing node pool locations will result in nodes being added and/or removed. Corresponds to the JSON property `locations` @return [Array<String>]
NodeManagement
defines the set of node management services turned on for the node pool. Corresponds to the JSON property `management` @return [Google::Apis::ContainerV1::NodeManagement]
Constraints applied to pods. Corresponds to the JSON property `maxPodsConstraint` @return [Google::Apis::ContainerV1::MaxPodsConstraint]
The name of the node pool. Corresponds to the JSON property `name` @return [String]
Parameters for node pool-level network config. Corresponds to the JSON property `networkConfig` @return [Google::Apis::ContainerV1::NodeNetworkConfig]
- Output only
-
The pod CIDR block size per node in this node pool.
Corresponds to the JSON property `podIpv4CidrSize` @return [Fixnum]
- Output only
-
Server-defined URL for the resource.
Corresponds to the JSON property `selfLink` @return [String]
- Output only
-
The status of the nodes in this pool instance.
Corresponds to the JSON property `status` @return [String]
- Output only
-
Deprecated. Use conditions instead. Additional information about
the current status of this node pool instance, if available. Corresponds to the JSON property `statusMessage` @return [String]
These upgrade settings control the level of parallelism and the level of disruption caused by an upgrade. maxUnavailable controls the number of nodes that can be simultaneously unavailable. maxSurge controls the number of additional nodes that can be added to the node pool temporarily for the time of the upgrade to increase the number of available nodes. (maxUnavailable + maxSurge) determines the level of parallelism (how many nodes are being upgraded at the same time). Note: upgrades inevitably introduce some disruption since workloads need to be moved from old nodes to new, upgraded ones. Even if maxUnavailable=0, this holds true. (Disruption stays within the limits of PodDisruptionBudget, if it is configured.) Consider a hypothetical node pool with 5 nodes having maxSurge=2, maxUnavailable=1. This means the upgrade process upgrades 3 nodes simultaneously. It creates 2 additional ( upgraded) nodes, then it brings down 3 old (not yet upgraded) nodes at the same time. This ensures that there are always at least 4 nodes available. Corresponds to the JSON property `upgradeSettings` @return [Google::Apis::ContainerV1::UpgradeSettings]
The version of the Kubernetes of this node. Corresponds to the JSON property `version` @return [String]
