os_coe_cluster – Add/Remove COE cluster from OpenStack Cloud

New in version 2.8.

Synopsis

  • Add or Remove COE cluster from the OpenStack Container Infra service.

Requirements

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

  • openstacksdk
  • python >= 2.7

Parameters

Parameter Choices/Defaults Comments
api_timeout
integer
How long should the socket layer wait before timing out for API calls. If this is omitted, nothing will be passed to the requests library.
auth
dictionary
Dictionary containing auth information as needed by the cloud's auth plugin strategy. For the default password plugin, this would contain auth_url, username, password, project_name and any information about domains (for example, os_user_domain_name or os_project_domain_name) if the cloud supports them. For other plugins, this param will need to contain whatever parameters that auth plugin requires. This parameter is not needed if a named cloud is provided or OpenStack OS_* environment variables are present.
auth_type
string
Name of the auth plugin to use. If the cloud uses something other than password authentication, the name of the plugin should be indicated here and the contents of the auth parameter should be updated accordingly.
availability_zone
-
Ignored. Present for backwards compatibility
ca_cert
string
A path to a CA Cert bundle that can be used as part of verifying SSL API requests.

aliases: cacert
client_cert
string
A path to a client certificate to use as part of the SSL transaction.

aliases: cert
client_key
string
A path to a client key to use as part of the SSL transaction.

aliases: key
cloud
raw
Named cloud or cloud config to operate against. If cloud is a string, it references a named cloud config as defined in an OpenStack clouds.yaml file. Provides default values for auth and auth_type. This parameter is not needed if auth is provided or if OpenStack OS_* environment variables are present. If cloud is a dict, it contains a complete cloud configuration like would be in a section of clouds.yaml.
cluster_template_id
- / required
The template ID of cluster template.
discovery_url
-
Url used for cluster node discovery
docker_volume_size
-
The size in GB of the docker volume
flavor_id
-
The flavor of the minion node for this ClusterTemplate
interface
string
added in 2.3
    Choices:
  • admin
  • internal
  • public ←
Endpoint URL type to fetch from the service catalog.

aliases: endpoint_type
keypair
-
Name of the keypair to use.
labels
-
One or more key/value pairs
master_count
-
Default:
1
The number of master nodes for this cluster
master_flavor_id
-
The flavor of the master node for this ClusterTemplate
name
- / required
Name that has to be given to the cluster template
node_count
-
Default:
1
The number of nodes for this cluster
region_name
string
Name of the region.
state
-
    Choices:
  • present ←
  • absent
Indicate desired state of the resource.
timeout
integer
Default:
60
Timeout for creating the cluster in minutes. Default to 60 mins if not set
validate_certs
boolean
    Choices:
  • no ←
  • yes
Whether or not SSL API requests should be verified.
Before Ansible 2.3 this defaulted to yes.

aliases: verify
wait
boolean
    Choices:
  • no
  • yes ←
Should ansible wait until the requested resource is complete.

Notes

Note

  • The standard OpenStack environment variables, such as OS_USERNAME may be used instead of providing explicit values.
  • Auth information is driven by openstacksdk, which means that values can come from a yaml config file in /etc/ansible/openstack.yaml, /etc/openstack/clouds.yaml or ~/.config/openstack/clouds.yaml, then from standard environment variables, then finally by explicit parameters in plays. More information can be found at https://docs.openstack.org/openstacksdk/
