openstack.cloud.lb_health_monitor module – Add/Delete a health m nonitor to a pool in the load balancing service from OpenStack Cloud

Note

This module is part of the openstack.cloud collection (version 1.8.0).

You might already have this collection installed if you are using the ansible package. It is not included in ansible-core. To check whether it is installed, run ansible-galaxy collection list.

To install it, use: ansible-galaxy collection install openstack.cloud.

To use it in a playbook, specify: openstack.cloud.lb_health_monitor.

Synopsis

• Add or Remove a health monitor to/from a pool in the OpenStack load-balancer service.

Requirements

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

• openstacksdk

• openstacksdk >= 0.12.0

• python >= 3.6

Parameters

Parameter	Comments
admin_state_up boolean	The admin state of the helath monitor true for up or false for down Choices: no yes ← (default)
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, user_domain_name or 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 string	Ignored. Present for backwards compatibility
ca_cert aliases: cacert string	A path to a CA Cert bundle that can be used as part of verifying SSL API requests.
client_cert aliases: cert string	A path to a client certificate to use as part of the SSL transaction.
client_key aliases: key string	A path to a client key to use as part of the SSL transaction.
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.
delay string / required	the interval, in seconds, between health checks.
expected_codes string	The list of HTTP status codes expected in response from the member to declare it healthy. Specify one of the following values A single value, such as 200 A list, such as 200, 202 A range, such as 200-204 Default: “200”
http_method string	The HTTP method that the health monitor uses for requests. One of CONNECT, DELETE, GET, HEAD, OPTIONS, PATCH, POST, PUT, or TRACE. The default is GET. Choices: GET ← (default) CONNECT DELETE HEAD OPTIONS PATCH POST PUT TRACE
interface aliases: endpoint_type string	Endpoint URL type to fetch from the service catalog. Choices: admin internal public ← (default)
max_retries string / required	The number of successful checks before changing the operating status of the member to ONLINE.
max_retries_down string	The number of allowed check failures before changing the operating status of the member to ERROR. A valid value is from 1 to 10. The default is 3. Default: “3”
name string / required	Name that has to be given to the health monitor
pool string / required	The pool name or id to monitor by the health monitor.
region_name string	Name of the region.
resp_timeout integer / required	The time, in seconds, after which a health check times out. Must be less than delay
state string	Should the resource be present or absent. Choices: present ← (default) absent
timeout integer	How long should ansible wait for the requested resource. Default: 180
type string	One of HTTP, HTTPS, PING, SCTP, TCP, TLS-HELLO, or UDP-CONNECT. Choices: HTTP ← (default) HTTPS PING SCTP TCP TLS-HELLO UDP-CONNECT
url_path string	The HTTP URL path of the request sent by the monitor to test the health of a backend member. Must be a string that begins with a forward slash (/). The default URL path is /. Default: “/”
validate_certs aliases: verify boolean	Whether or not SSL API requests should be verified. Before Ansible 2.3 this defaulted to yes. Choices: no yes
wait boolean	Should ansible wait until the requested resource is complete. Choices: no yes ← (default)

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/
