Parameters

Parameter Choices/Defaults Comments

  • 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.
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 log location in the S3 bucket.
If you don't specify a prefix, the access logs are stored in the root of the bucket.
Cannot begin or end with a slash.
aws_access_key
string
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
string
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
debug_botocore_endpoint_logs
boolean
added in 2.8
    Choices:
  • no ←
  • yes
Use a botocore.endpoint logger to parse the unique (rather than total) "resource:action" API calls made during a task, outputing the set to the resource_actions key in the task results. Use the aws_resource_action callback to output to total list made during a playbook. The ANSIBLE_DEBUG_BOTOCORE_LOGS environment variable may also be used.
deletion_protection
boolean
    Choices:
  • no ←
  • yes
Indicates whether deletion protection for the ELB is enabled.
ec2_url
string
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
boolean
added in 2.6
    Choices:
  • no ←

Indicates whether to enable HTTP2 routing.
idle_timeout
-
Default:
60

wait
boolean
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
