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

  • boto
  • boto3
  • python >= 2.6

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.

security_token

-

added in 1.6

AWS STS security token. If not set then the value of the AWS_SECURITY_TOKEN or EC2_SECURITY_TOKEN environment variable is used.

state

- / required

  • present

  • absent

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


Examples

# Simple example to create a lambda function and publish a version
- hosts: localhost
  gather_facts: no
  vars:
    state: present
    project_folder: /path/to/deployment/package
    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 }}"
