Notes¶
Note
If parameters are not set within the module, the following environment variables can be used in decreasing order of precedence
AWS_URLorEC2_URL,AWS_PROFILEorAWS_DEFAULT_PROFILE,AWS_ACCESS_KEY_IDorAWS_ACCESS_KEYorEC2_ACCESS_KEY,AWS_SECRET_ACCESS_KEYorAWS_SECRET_KEYorEC2_SECRET_KEY,AWS_SECURITY_TOKENorEC2_SECURITY_TOKEN,AWS_REGIONorEC2_REGION,AWS_CA_BUNDLEAnsible uses the boto configuration file (typically ~/.boto) if no credentials are provided. See https://boto.readthedocs.io/en/latest/boto_config_tut.html
AWS_REGIONorEC2_REGIONcan be typically be used to specify the AWS region, when required, but this can also be configured in the boto config file

# Rolling ASG Updates
