  • boto

  • boto3

  • python >= 2.6

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.

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
bucket_name
string / required
S3 bucket name
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_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.
event_name
string / required
unique name for event notification on bucket
events
list / required
    Choices:
  • s3:ObjectCreated:*
  • s3:ObjectCreated:Put
  • s3:ObjectCreated:Post
  • s3:ObjectCreated:Copy

  • s3:ObjectRemoved:*
  • s3:ObjectRemoved:Delete
  • s3:ObjectRemoved:DeleteMarkerCreated
  • s3:ObjectRestore:Post
  • s3:ObjectRestore:Completed
  • s3:ReducedRedundancyLostObject
Events that you want to be triggering notifications. You can select multiple events to send to the same destination, you can set up different events to send to different destinations, and you can set up a prefix or suffix for an event. However, for each bucket, individual events cannot have multiple configurations with overlapping prefixes or suffixes that could match the same object key.
lambda_alias
string
Name of the Lambda function alias. Mutually exclusive with lambda_version.
lambda_function_arn
string
The ARN of the lambda function.

aliases: function_arn
lambda_version
integer
Version of the Lambda function. Mutually exclusive with lambda_alias.
prefix
string
Optional prefix to limit the notifications to objects with keys that start with matching characters.
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
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
string / required
    Choices:
  • present ←
  • absent
Describes the desired state.
suffix
string
Optional suffix to limit the notifications to objects with keys that end with matching characters.
validate_certs
boolean
    Choices:
  • no
  • yes ←
When set to "no", SSL certificates will not be validated for boto versions >= 2.6.0.

Notes

Note

  • This module heavily depends on lambda_policy as you need to allow lambda:InvokeFunction permission for your lambda function.

  • 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
