Parameters

Parameter Choices/Defaults Comments
access_logs_enabled
bool
    Choices:
  • no
  • yes
Whether or not to enable access logs. When true, access_logs_s3_bucket must be set.
access_logs_s3_bucket
The name of the S3 bucket for the access logs. This attribute is required if access logs in Amazon S3 are enabled. The bucket must exist in the same region as the load balancer and have a bucket policy that grants Elastic Load Balancing permission to write to the bucket.
access_logs_s3_prefix
The prefix for the location in the S3 bucket. If you don't specify a prefix, the access logs are stored in the root of the bucket.
aws_access_key
AWS access key. If not set then the value of the AWS_ACCESS_KEY_ID, AWS_ACCESS_KEY or EC2_ACCESS_KEY environment variable is used.

aliases: ec2_access_key, access_key
aws_secret_key
AWS secret key. If not set then the value of the AWS_SECRET_ACCESS_KEY, AWS_SECRET_KEY, or EC2_SECRET_KEY environment variable is used.

aliases: ec2_secret_key, secret_key
deletion_protection
bool
    Choices:
  • no ←
  • yes
Indicates whether deletion protection for the ELB is enabled.
ec2_url
Url to use to connect to EC2 or your Eucalyptus cloud (by default the module will use EC2 endpoints). Ignored for modules where region is required. Must be specified for all other modules if region is not used. If not set then the value of the EC2_URL environment variable, if any, is used.
http2
bool

(added in 2.6)

purge_listeners
bool
    Choices:
  • no

If yes, existing listeners will be purged from the ELB to match exactly what is defined by listeners parameter. If the listeners parameter is not set then listeners will not be modified
purge_rules
bool

(added in 2.7)
    Choices:

wait
bool

(added in 2.6)
    Choices:
  • no ←
  • yes
Wait for the load balancer to have a state of 'active' before completing. A status check is performed every 15 seconds until a successful state is reached. An error is returned after 40 failed checks.
wait_timeout
(added in 2.6)
The time in seconds to use in conjunction with wait.

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.
  • If parameters are not set within the module, the following environment variables can be used in decreasing order of precedence AWS_URL or EC2_URL, AWS_ACCESS_KEY_ID or AWS_ACCESS_KEY or EC2_ACCESS_KEY, AWS_SECRET_ACCESS_KEY or AWS_SECRET_KEY or EC2_SECRET_KEY, AWS_SECURITY_TOKEN or EC2_SECURITY_TOKEN, AWS_REGION or EC2_REGION
  • Ansible uses the boto configuration file (typically ~/.boto) if no credentials are provided. See https://boto.readthedocs.io/en/latest/boto_config_tut.html
  • AWS_REGION or EC2_REGION can be typically be used to specify the AWS region, when required, but this can also be configured in the boto config file
