Requirements

The below requirements are needed on the host that executes this module.

Parameters

Parameter Choices/Defaults Comments
api_user
string
The OCID of the user, on whose behalf, OCI APIs are invoked. If not set, then the value of the OCI_USER_OCID environment variable, if any, is used. This option is required if the user is not specified through a configuration file (See config_file_location). To get the user's OCID, please refer https://docs.us-phoenix-1.oraclecloud.com/Content/API/Concepts/apisigningkey.htm.
api_user_fingerprint
string
Fingerprint for the key pair being used. If not set, then the value of the OCI_USER_FINGERPRINT environment variable, if any, is used. This option is required if the key fingerprint is not specified through a configuration file (See config_file_location). To get the key pair's fingerprint value please refer https://docs.us-phoenix-1.oraclecloud.com/Content/API/Concepts/apisigningkey.htm.
api_user_key_file
string
Full path and filename of the private key (in PEM format). If not set, then the value of the OCI_USER_KEY_FILE variable, if any, is used. This option is required if the private key is not specified through a configuration file (See config_file_location). If the key is encrypted with a pass-phrase, the api_user_key_pass_phrase option must also be provided.
api_user_key_pass_phrase
string
Passphrase used by the key referenced in api_user_key_file, if it is encrypted. If not set, then the value of the OCI_USER_KEY_PASS_PHRASE variable, if any, is used. This option is required if the key passphrase is not specified through a configuration file (See config_file_location).
auth_type
string
    Choices:
  • api_key ←
  • instance_principal
The type of authentication to use for making API requests. By default auth_type="api_key" based authentication is performed and the API key (see api_user_key_file) in your config file will be used. If this 'auth_type' module option is not specified, the value of the OCI_ANSIBLE_AUTH_TYPE, if any, is used. Use auth_type="instance_principal" to use instance principal based authentication when running ansible playbooks within an OCI compute instance.
cluster_id
-
The OCID of the cluster to which this node pool is attached. Required to create a node pool.
compartment_id
-
The OCID of the compartment in which the node pool exists. Required to create a node pool.
config_file_location
string
Path to configuration file. If not set then the value of the OCI_CONFIG_FILE environment variable, if any, is used. Otherwise, defaults to ~/.oci/config.
config_profile_name
string
The profile to load from the config file referenced by config_file_location. If not set, then the value of the OCI_CONFIG_PROFILE environment variable, if any, is used. Otherwise, defaults to the "DEFAULT" profile in config_file_location.
count_of_nodes_to_wait
-
Default:
1
Number of nodes in the node pool to wait for getting into a lifecycle state specified using wait_until when wait=yes and state=present.
force_create
boolean
    Choices:
  • no ←
  • yes
Whether to attempt non-idempotent creation of a resource. By default, create resource is an idempotent operation, and doesn't create the resource if it already exists. Setting this option to true, forcefully creates a copy of the resource, even if it already exists.This option is mutually exclusive with key_by.
initial_node_labels
-
A list of key/value pairs to add to nodes after they join the Kubernetes cluster.
key
- / required
The key of the pair.
value
- / required
The value of the pair.
key_by
list

kubernetes_version
-
The version of Kubernetes to install on the nodes in the node pool. Required to create a node pool.
name
-
The name of the node pool. Avoid entering confidential information. Required to create a node pool.
node_image_name

This option is required if the region is not specified through a configuration file (See config_file_location). Please refer to https://docs.us-phoenix-1.oraclecloud.com/Content/General/Concepts/regions.htm for more information on OCI regions.
ssh_public_key
-
The SSH public key to add to each node in the node pool.
state

    Choices:
  • present ←
  • absent
Create or update a node pool with state=present. Use state=absent to delete a node pool.
subnet_ids
-
The OCIDs of the subnets in which to place nodes for this node pool. Required to create a node pool.
tenancy
string
OCID of your tenancy. If not set, then the value of the OCI_TENANCY variable, if any, is used. This option is required if the tenancy OCID is not specified through a configuration file (See config_file_location).

Default:
1200
Time, in seconds, to wait when wait=yes.
wait_until
-
Default:
"ACTIVE"
The lifecycle state of a node in node pool to wait for while creating or updating a node pool with wait=yes.
