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

# Note: None of these examples set aws_access_key, aws_secret_key, or region.
# It is assumed that their matching environment variables are set.

# Basic example
- elasticache:
    name: "test-please-delete"
    state: present
    engine: memcached
    cache_engine_version: 1.4.14
    node_type: cache.m1.small
    num_nodes: 1
    cache_port: 11211
    cache_security_groups:
      - default
    zone: us-east-1d


# Ensure cache cluster is gone
- elasticache:
    name: "test-please-delete"
    state: absent

# Reboot cache cluster
- elasticache:
    name: "test-please-delete"
    state: rebooted
