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.
If profile is set this parameter is ignored.
Passing the aws_access_key and profile options at the same time has been deprecated and the options will be made mutually exclusive after 2022-06-01.

aliases: ec2_access_key, access_key
aws_ca_bundle
path
The location of a CA Bundle to use when validating SSL certificates.
Only used for boto3 based modules.
Note: The CA Bundle is read 'module' side and may need to be explicitly copied from the controller if not run locally.
aws_config
dictionary
A dictionary to modify the botocore configuration.
Only the 'user_agent' key is used for boto modules. See http://boto.cloudhackers.com/en/latest/boto_config_tut.html#boto for more boto configuration.
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.
If profile is set this parameter is ignored.
Passing the aws_secret_key and profile options at the same time has been deprecated and the options will be made mutually exclusive after 2022-06-01.

aliases: ec2_secret_key, secret_key
dead_letter_arn
string
The parent object that contains the target Amazon Resource Name (ARN) of an Amazon SQS queue or Amazon SNS topic.
debug_botocore_endpoint_logs
boolean
    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.
description
string
A short, user-defined function description. Lambda does not use this value. Assign a meaningful description as you see fit.
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.

aliases: aws_endpoint_url, endpoint_url
environment_variables
dictionary
A dictionary of environment variables the Lambda function is given.
handler
string
The function within your code that Lambda calls to begin execution.
memory_size
integer
Default:
128
The amount of memory, in MB, your Lambda function is given.
name
string / required
The name you want to assign to the function you are uploading. Cannot be changed.
profile
string
Uses a boto profile. Only works with boto >= 2.24.0.
Using profile will override aws_access_key, aws_secret_key and security_token and support for passing them at the same time as profile has been deprecated.
aws_access_key, aws_secret_key and security_token will be made mutually exclusive with profile after 2022-06-01.

aliases: aws_profile
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
role
string
The Amazon Resource Name (ARN) of the IAM role that Lambda assumes when it executes your function to access any other Amazon Web Services (AWS) resources. You may use the bare ARN if the role belongs to the same AWS account.
Required when state=present.
runtime
string
The runtime environment for the Lambda function you are uploading.
Required when creating a function. Uses parameters as described in boto3 docs.
Required when state=present.
s3_bucket
string
Amazon S3 bucket name where the .zip file containing your deployment package is stored.
If state=present then either zip_file or s3_bucket must be present.
s3_bucket and s3_key are required together.
s3_key
string
The Amazon S3 object (the deployment package) key name you want to upload.
s3_bucket and s3_key are required together.
s3_object_version
string
The Amazon S3 object (the deployment package) version you want to upload.
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.
If profile is set this parameter is ignored.
Passing the security_token and profile options at the same time has been deprecated and the options will be made mutually exclusive after 2022-06-01.

aliases: aws_security_token, access_token
state
string
    Choices:
  • present ←
  • absent
Create or delete Lambda function.
tags
dictionary
tag dict to apply to the function (requires botocore 1.5.40 or above).
timeout
integer
Default:
3
The function maximum execution time in seconds after which Lambda should terminate the function.
tracing_mode
string
    Choices:
  • Active
  • PassThrough
Set mode to 'Active' to sample and trace incoming requests with AWS X-Ray. Turned off (set to 'PassThrough') by default.
validate_certs
boolean

  • no
  • yes ←
When set to "no", SSL certificates will not be validated for boto versions >= 2.6.0.
vpc_security_group_ids
list / elements=string
List of VPC security group IDs to associate with the Lambda function.
Required when vpc_subnet_ids is used.
vpc_subnet_ids
list / elements=string
List of subnet IDs to run Lambda function in.

If set, vpc_security_group_ids must also be set.
zip_file
string
A .zip file containing your deployment package
If state=present then either zip_file or s3_bucket must be present.

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_PROFILE or AWS_DEFAULT_PROFILE, 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, AWS_CA_BUNDLE

  • 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
