Reduce the number of vCPU exposed to the instance.
Those parameters can only be set at instance launch. The two suboptions threads_per_core and core_count are mandatory.
See https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/instance-optimize-cpu.html for combinations available.

|
|
|
debug_botocore_endpoint_logs
boolean
added in 2.8 |
|
Use a botocore.endpoint logger to parse the unique (rather than total) "resource:action" API calls made during a task, outputing the set to the resource_actions key in the task results. Use the aws_resource_action callback to output to total list made during a playbook. The ANSIBLE_DEBUG_BOTOCORE_LOGS environment variable may also be used.
|
|
|
detailed_monitoring
boolean
|
|
Whether to allow detailed cloudwatch metrics to be collected, enabling more detailed alerting.
|
|

|
|
|
ec2_url
string
|
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.

See https://docs.aws.amazon.com/AWSEC2/latest/APIReference/API_DescribeInstances.html. for possible filters. Filter names and values are case sensitive. By default, instances are filtered for counting by their "Name" tag, base AMI, state (running, by default), and subnet ID. Any queryable filter can be used. Good candidates are specific tags, SSH keys, or security groups.

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_ACCESS_KEY_IDorAWS_ACCESS_KEYorEC2_ACCESS_KEY,AWS_SECRET_ACCESS_KEYorAWS_SECRET_KEYorEC2_SECRET_KEY,AWS_SECURITY_TOKENorEC2_SECURITY_TOKEN,AWS_REGIONorEC2_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_REGIONorEC2_REGIONcan be typically be used to specify the AWS region, when required, but this can also be configured in the boto config file
