lambda_alias - Creates, updates or deletes AWS Lambda function aliases.

New in version 2.2.

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.

    deployment_package: lambda.zip
    account: 123456789012
    production_version: 5
  tasks:
  - name: AWS Lambda Function
    lambda:
      state: "{{ state | default('present') }}"
      name: myLambdaFunction
      publish: True
      description: lambda function description
      code_s3_bucket: package-bucket
      code_s3_key: "lambda/{{ deployment_package }}"
      local_path: "{{ project_folder }}/{{ deployment_package }}"
      runtime: python2.7
      timeout: 5
      handler: lambda.handler
      memory_size: 128
      role: "arn:aws:iam::{{ account }}:role/API2LambdaExecRole"

  - name: show results
    debug:
      var: 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_facts.FunctionName }} "
    lambda_alias:
      state: "{{ state | default('present') }}"
      function_name: "{{ 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 = '$LATEST')
  - name: "alias 'QA' for function {{ lambda_facts.FunctionName }} "
    lambda_alias:
      state: "{{ state | default('present') }}"
      function_name: "{{ lambda_facts.FunctionName }}"
      name: QA
      version: "{{ lambda_facts.Version }}"
      description: "QA is version {{ lambda_facts.Version }}"
    when: lambda_facts.Version != "$LATEST"

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

Return Values

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

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


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 http://boto.readthedocs.org/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
