Examples

# Create Lambda functions
tasks:
- name: looped creation
  lambda:
    name: '{{ item.name }}'
    state: present
    zip_file: '{{ item.zip_file }}'
    runtime: 'python2.7'
    role: 'arn:aws:iam::987654321012:role/lambda_basic_execution'
    handler: 'hello_python.my_handler'
    vpc_subnet_ids:
    - subnet-123abcde
    - subnet-edcba321
    vpc_security_group_ids:
    - sg-123abcde
    - sg-edcba321
    environment_variables: '{{ item.env_vars }}'
  with_items:
    - name: HelloWorld
      zip_file: hello-code.zip
      env_vars:
        key1: "first"
        key2: "second"
    - name: ByeBye
      zip_file: bye-code.zip
      env_vars:
        key1: "1"
        key2: "2"

# Basic Lambda function deletion
tasks:
- name: Delete Lambda functions HelloWorld and ByeBye
  lambda:
    name: '{{ item }}'
    state: absent
  with_items:
    - HelloWorld
    - ByeBye

Return Values

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

name description returned type sample
output the data returned by get_function in boto3 success dict {'code': {'repository_type': 'S3', 'location': 'an S3 URL'}, 'configuration': {'description': 'string', 'function_arn': 'string', 'handler': 'string', 'timeout': 123, 'last_modified': 'string', 'role': 'string', 'version': 'string', 'code_sha256': 'string', 'memory_size': 123, 'runtime': 'nodejs', 'code_size': 123, 'function_name': 'string'}}


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
