elb_instance – De-registers or registers instances from EC2 ELBs

Synopsis

  • This module de-registers or registers an AWS EC2 instance from the ELBs that it belongs to.
  • Returns fact “ec2_elbs” which is a list of elbs attached to the instance if state=absent is passed as an argument.
  • Will be marked changed when called only if there are ELBs found to operate on.

Requirements

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

  • python >= 2.6
  • boto

Parameters

Parameter Choices/Defaults Comments
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.

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.
ec2_elbs
-
List of ELB names, required for registration. The ec2_elbs fact should be used if there was a previous de-register.
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.
enable_availability_zone
boolean
    Choices:
  • no
  • yes ←
Whether to enable the availability zone of the instance on the target ELB if the availability zone has not already been enabled. If set to no, the task will fail if the availability zone is not enabled on the ELB.
instance_id
- / required
EC2 Instance ID
profile
string
Uses a boto profile. Only works with boto >= 2.24.0.
region
string
The AWS region to use. If not specified then the value of the AWS_REGION or EC2_REGION environment variable, if any, is used. See http://docs.aws.amazon.com/general/latest/gr/rande.html#ec2_region

aliases: aws_region, ec2_region
security_token
string
AWS STS security token. If not set then the value of the AWS_SECURITY_TOKEN or EC2_SECURITY_TOKEN environment variable is used.

aliases: access_token
state
- / required
    Choices:
  • present
  • absent
register or deregister the instance
validate_certs
boolean
    Choices:
  • no
  • yes ←
When set to "no", SSL certificates will not be validated for boto versions >= 2.6.0.
wait
boolean
    Choices:
  • no
  • yes ←
Wait for instance registration or deregistration to complete successfully before returning.
wait_timeout
-
Default:
0
Number of seconds to wait for an instance to change state. If 0 then this module may return an error if a transient error occurs. If non-zero then any transient errors are ignored until the timeout is reached. Ignored when wait=no.

Notes

Note

  • 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
