os_server_metadata – Add/Update/Delete Metadata in Compute Instances from OpenStack

New in version 2.6.

Synopsis

  • Add, Update or Remove metadata in compute instances from OpenStack.

Requirements

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

  • openstacksdk
  • python >= 2.7
  • shade

Parameters

Parameter Choices/Defaults Comments
api_timeout
-
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 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 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
-
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
-
Availability zone in which to create the snapshot.
cacert
-
A path to a CA Cert bundle that can be used as part of verifying SSL API requests.
cert
-
A path to a client certificate to use as part of the SSL transaction.
cloud
-
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.
interface
-
added in 2.3
    Choices:
  • public ←
  • internal
  • admin
Endpoint URL type to fetch from the service catalog.

aliases: endpoint_type
key
-
A path to a client key to use as part of the SSL transaction.
meta
- / required
A list of key value pairs that should be provided as a metadata to the instance or a string containing a list of key-value pairs. Eg: meta: "key1=value1,key2=value2"
region_name
-
Name of the region.
server
- / required
Name of the instance to update the metadata

aliases: name
state
-
    Choices:
  • present ←
  • absent
Should the resource be present or absent.
timeout
-
Default:
180
How long should ansible wait for the requested resource.
verify
boolean
    Choices:
  • no
  • yes
Whether or not SSL API requests should be verified. Before 2.3 this defaulted to True.

aliases: validate_certs
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 os-client-config, 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 http://docs.openstack.org/developer/os-client-config

Examples

# Creates or updates hostname=test1 as metadata of the server instance vm1
- name: add metadata to compute instance
  hosts: localhost
  tasks:
  - name: add metadata to instance
    os_server_metadata:
        state: present
        auth:
            auth_url: https://openstack-api.example.com:35357/v2.0/
            username: admin
            password: admin
            project_name: admin
        name: vm1
        meta:
            hostname: test1
            group: group1

# Removes the keys under meta from the instance named vm1
- name: delete metadata from compute instance
  hosts: localhost
  tasks:
  - name: delete metadata from instance
    os_server_metadata:
        state: absent
        auth:
            auth_url: https://openstack-api.example.com:35357/v2.0/
            username: admin
            password: admin
            project_name: admin
        name: vm1
        meta:
            hostname:
            group:
