gcp_container_node_pool_info – Gather info for GCP NodePool

New in version 2.8.


Synopsis

  • Gather info for GCP NodePool
  • This module was called gcp_container_node_pool_facts before Ansible 2.9. The usage has not changed.

Aliases: gcp_container_node_pool_facts

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

  • 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 "Template: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
    service_account_file: "/tmp/auth.pem"

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


autoscaling

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" }.

string

success

Minimum CPU platform to be used by this instance. The instance may be scheduled on the specified or newer CPU platform .


oauthScopes

list

success

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.


preemptible

boolean

success

Whether the nodes are created as preemptible VM instances. See: https://cloud.google.com/compute/docs/instances/preemptible for more information about preemptible VM instances.


serviceAccount

string

success

The Google Cloud Platform Service Account to be used by the node VMs. If no Service Account is specified, the "default" service account is used.


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

location

string

success

The location where the node pool is deployed.


management

complex

success

Management configuration for this NodePool.


autoRepair

boolean

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.


upgradeOptions

complex

autoUpgradeStartTime

string

success

This field is set when upgrades are about to commence with the approximate start time for the upgrades, in RFC3339 text format.
