Notes¶
Note
- In order to use the assumed role in a following playbook task you must pass the access_key, access_secret and access_token.
- If parameters are not set within the module, the following environment variables can be used in decreasing order of precedence
AWS_URL
orEC2_URL
,AWS_ACCESS_KEY_ID
orAWS_ACCESS_KEY
orEC2_ACCESS_KEY
,AWS_SECRET_ACCESS_KEY
orAWS_SECRET_KEY
orEC2_SECRET_KEY
,AWS_SECURITY_TOKEN
orEC2_SECURITY_TOKEN
,AWS_REGION
orEC2_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
orEC2_REGION
can be typically be used to specify the AWS region, when required, but this can also be configured in the boto config file
