Whether or not to wait for the network load balancer to reach the desired state.

Choices:

  • false

  • true

wait_timeout

integer

Notes

Note

  • Listeners are matched based on port. If a listener’s port is changed then a new listener will be created.

  • Listener rules are matched based on priority. If a rule’s priority is changed then a new rule will be created.

  • Caution: Environment variables and configuration files are read from the Ansible ‘host’ context and not the ‘controller’ context. Files may need to be explicitly copied to the ‘host’.

  • The AWS SDK (boto3) that Ansible uses may also read defaults for credentials and other settings, such as the region, from its configuration files in the Ansible ‘host’ context (typically ~/.aws/credentials). See https://boto3.amazonaws.com/v1/documentation/api/latest/guide/credentials.html for more information.
