Parameters

Parameter Choices/Defaults Comments
auth_kind
string / required
    Choices:
  • application
  • machineaccount
  • serviceaccount
The type of credential used.
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 }}"
env_type
string
Specifies which Ansible environment you're running this module within.
This should not be set unless you know what you're doing.
This only alters the User Agent string for any API requests.
location
string / required
added in 2.8
The location where the node pool is deployed.

aliases: region, zone
project
string
The Google Cloud Platform project to use.
scopes
list
Array of scopes to be used.
service_account_contents
jsonarg
The contents of a Service Account JSON file, either in a dictionary or as a JSON string that represents it.
service_account_email
string
An optional service account email address if machineaccount is selected and the user does not wish to use the default email.
service_account_file
path
The path of a Service Account JSON file if serviceaccount is selected as type.

Notes

Note

  • for authentication, you can set service_account_file using the c(gcp_service_account_file) env variable.
  • for authentication, you can set service_account_contents using the c(GCP_SERVICE_ACCOUNT_CONTENTS) env variable.
  • For authentication, you can set service_account_email using the GCP_SERVICE_ACCOUNT_EMAIL env variable.
  • For authentication, you can set auth_kind using the GCP_AUTH_KIND env variable.
  • For authentication, you can set scopes using the GCP_SCOPES env variable.
  • Environment variables values will only be used if the playbook values are not set.
  • The service_account_email and service_account_file options are mutually exclusive.

Examples

- name: get info on a node pool
  gcp_container_node_pool_info:
    cluster: "{{ cluster }}"
    location: us-central1-a
    project: test_project
    auth_kind: serviceaccount

Return Values

Common return values are documented here, the following are the fields unique to this module:

Key Returned Description
resources
complex
always
List of resources

complex
success
Autoscaler configuration for this NodePool. Autoscaler is enabled only if a valid configuration is present.

enabled
boolean
success
Is autoscaling enabled for this node pool.

maxNodeCount
integer
success
Maximum number of nodes in the NodePool. Must be >= minNodeCount.
There has to enough quota to scale up the cluster.

minNodeCount
integer
success
Minimum number of nodes in the NodePool. Must be >= 1 and <= maxNodeCount.

cluster
dictionary
success
The cluster this node pool belongs to.

conditions
complex
success
Which conditions caused the current node pool state.

code
string
success
Machine-friendly representation of the condition.

config
complex
success
The node configuration of the pool.

accelerators
complex
success
A list of hardware accelerators to be attached to each node.

acceleratorCount
integer
success
The number of the accelerator cards exposed to an instance.

acceleratorType
string
success
The accelerator type resource name.

diskSizeGb
integer
success
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.

diskType
string
success
Type of the disk attached to each node (e.g. 'pd-standard' or 'pd-ssd') If unspecified, the default disk type is 'pd-standard' .

imageType
string
success
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
success
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" }.

localSsdCount
integer
success
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.

machineType
string
success
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
success
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" }.

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.

preemptible

tags
list
success
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

success
List of kubernetes taints to be applied to each node.

effect
string
success
Effect for taint.

key
string
success
Key for taint.

value
string
success

string
success
The location where the node pool is deployed.

management
complex
success
Management configuration for this NodePool.

autoRepair
boolean
success

autoUpgrade
boolean
success
A flag that specifies whether node auto-upgrade is enabled for the node pool. If enabled, node auto-upgrade helps keep the nodes in your node pool up to date with the latest release version of Kubernetes.
