Synopsis ¶

This module allows the management of AWS Lambda functions aliases via the Ansible framework. It is idempotent and supports “Check” mode. Use module lambda to manage the lambda function itself and lambda_event to manage event source mappings.

Requirements ¶

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

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
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.
description -		A short, user-defined function alias description.
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.
function_name - / required		The name of the function alias.
name - / required		Name of the function alias. aliases: alias_name
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 - / required	Choices: present ← absent	Describes the desired state.
validate_certs boolean	Choices: no yes ←	When set to "no", SSL certificates will not be validated for boto versions >= 2.6.0.
version -		Version associated with the Lambda function alias. A value of 0 (or omitted parameter) sets the alias to the $LATEST version. aliases: function_version

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

    register: lambda_info
  - name: show results
    debug:
      msg: "{{ lambda_info['lambda_facts'] }}"

# The following will set the Dev alias to the latest version ($LATEST) since version is omitted (or = 0)
  - name: "alias 'Dev' for function {{ lambda_info.lambda_facts.FunctionName }} "
    lambda_alias:
      state: "{{ state | default('present') }}"
      function_name: "{{ lambda_info.lambda_facts.FunctionName }}"
      name: Dev
      description: Development is $LATEST version

# The QA alias will only be created when a new version is published (i.e. not = '$LATEST')
  - name: "alias 'QA' for function {{ lambda_info.lambda_facts.FunctionName }} "
    lambda_alias:
      state: "{{ state | default('present') }}"
      function_name: "{{ lambda_info.lambda_facts.FunctionName }}"
      name: QA
      version: "{{ lambda_info.lambda_facts.Version }}"
      description: "QA is version {{ lambda_info.lambda_facts.Version }}"
    when: lambda_info.lambda_facts.Version != "$LATEST"

# The Prod alias will have a fixed version based on a variable
  - name: "alias 'Prod' for function {{ lambda_info.lambda_facts.FunctionName }} "
    lambda_alias:
      state: "{{ state | default('present') }}"
      function_name: "{{ lambda_info.lambda_facts.FunctionName }}"
      name: Prod
      version: "{{ production_version }}"
      description: "Production is version {{ production_version }}"

Return Values ¶

Common return values are documented here, the following are the fields unique to this module:

Key	Returned	Description
alias_arn string	success	Full ARN of the function, including the alias Sample: arn:aws:lambda:us-west-2:123456789012:function:myFunction:dev
description string	success	A short description of the alias Sample: The development stage for my hot new app
function_version string	success	The qualifier that the alias refers to Sample: $LATEST
name string	success	The name of the alias assigned Sample: dev
