Synopsis
- 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.
Requirements
The below requirements are needed on the host that executes this module.
- python >= 2.6
- requests >= 2.18.4
- google-auth >= 1.3.0
Parameters
Parameter | Choices/Defaults | Comments | ||
---|---|---|---|---|
auth_kind string / required |
| The type of credential used. | ||
autoscaling dictionary | Autoscaler configuration for this NodePool. Autoscaler is enabled only if a valid configuration is present. | |||
enabled boolean |
| Is autoscaling enabled for this node pool. | ||
max_node_count integer | Maximum number of nodes in the NodePool. Must be >= minNodeCount. There has to enough quota to scale up the cluster. | |||
min_node_count integer | Minimum number of nodes in the NodePool. Must be >= 1 and <= maxNodeCount. | |||
cluster dictionary / required | The cluster this node pool belongs to. This field represents a link to a Cluster resource in GCP. It can be specified in two ways. First, you can place a dictionary with key 'name' and value of your resource's name Alternatively, you can add `register: name-of-resource` to a gcp_container_cluster task and then set this cluster field to "{{ name-of-resource }}" | |||
conditions list / elements=dictionary | Which conditions caused the current node pool state. | |||
code string | Machine-friendly representation of the condition. Some valid choices include: "UNKNOWN", "GCE_STOCKOUT", "GKE_SERVICE_ACCOUNT_DELETED", "GCE_QUOTA_EXCEEDED", "SET_BY_OPERATOR" | |||
config dictionary | The node configuration of the pool. | |||
accelerators list / elements=dictionary | A list of hardware accelerators to be attached to each node. | |||
accelerator_count integer | The number of the accelerator cards exposed to an instance. | |||
accelerator_type string | The accelerator type resource name. | |||
disk_size_gb integer | Size of the disk attached to each node, specified in GB. The smallest allowed disk size is 10GB. If unspecified, the default disk size is 100GB. | |||
disk_type string | Type of the disk attached to each node (e.g. 'pd-standard' or 'pd-ssd') If unspecified, the default disk type is 'pd-standard' . | |||
image_type string | The image type to use for this node. Note that for a given image type, the latest version of it will be used. | |||
labels dictionary | The map of Kubernetes labels (key/value pairs) to be applied to each node. These will added in addition to any default label(s) that Kubernetes may apply to the node. In case of conflict in label keys, the applied set may differ depending on the Kubernetes version -- it's best to assume the behavior is undefined and conflicts should be avoided. For more information, including usage and the valid values, see: http://kubernetes.io/v1.1/docs/user-guide/labels.html An object containing a list of "key": value pairs. Example: { "name": "wrench", "mass": "1.3kg", "count": "3" }. | |||
local_ssd_count integer | The number of local SSD disks to be attached to the node. The limit for this value is dependant upon the maximum number of disks available on a machine per zone. See: https://cloud.google.com/compute/docs/disks/local-ssd#local_ssd_limits for more information. | |||
machine_type string | The name of a Google Compute Engine machine type (e.g. n1-standard-1). If unspecified, the default machine type is n1-standard-1. | |||
metadata dictionary | The metadata key/value pairs assigned to instances in the cluster. Keys must conform to the regexp [a-zA-Z0-9-_]+ and be less than 128 bytes in length. These are reflected as part of a URL in the metadata server. Additionally, to avoid ambiguity, keys must not conflict with any other metadata keys for the project or be one of the four reserved keys: "instance-template", "kube-env", "startup-script", and "user-data" Values are free-form strings, and only have meaning as interpreted by the image running in the instance. The only restriction placed on them is that each value's size must be less than or equal to 32 KB. The total size of all keys and values must be less than 512 KB. An object containing a list of "key": value pairs. Example: { "name": "wrench", "mass": "1.3kg", "count": "3" }. | |||
min_cpu_platform string | Minimum CPU platform to be used by this instance. The instance may be scheduled on the specified or newer CPU platform . | |||
oauth_scopes list / elements=string | The set of Google API scopes to be made available on all of the node VMs under the "default" service account. The following scopes are recommended, but not required, and by default are not included: https://www.googleapis.com/auth/compute is required for mounting persistent storage on your nodes.
https://www.googleapis.com/auth/devstorage.read_only is required for communicating with gcr.io (the Google Container Registry). If unspecified, no scopes are added, unless Cloud Logging or Cloud Monitoring are enabled, in which case their required scopes will be added. | |||

The attestation is performed against the integrity policy baseline. This baseline is initially derived from the implicitly trusted boot image when the instance is created. | ||
enable_secure_boot boolean |
| Defines whether the instance has Secure Boot enabled. Secure Boot helps ensure that the system only runs authentic software by verifying the digital signature of all boot components, and halting the boot process if signature verification fails. | ||
tags list / elements=string | The list of instance tags applied to all nodes. Tags are used to identify valid sources or targets for network firewalls and are specified by the client during cluster or node pool creation. Each tag within the list must comply with RFC1035. | |||
taints list / elements=dictionary | List of kubernetes taints to be applied to each node. | |||
effect string | Effect for taint. | |||
