## Synopsis

- maintains ec2 security groups. This module has a dependency on python-boto >= 2.5

## Requirements

The below requirements are needed on the host that executes this module.

- boto

- boto3

- python >= 2.6

## Parameters

Parameter | Choices/Defaults | Comments
--- | --- | ---
aws_access_key string |  | AWS access key. If not set then the value of the AWS_ACCESS_KEY_ID, AWS_ACCESS_KEY or EC2_ACCESS_KEY environment variable is used. aliases: ec2_access_key, access_key
aws_secret_key string |  | AWS secret key. If not set then the value of the AWS_SECRET_ACCESS_KEY, AWS_SECRET_KEY, or EC2_SECRET_KEY environment variable is used. aliases: ec2_secret_key, secret_key
debug_botocore_endpoint_logs boolean added in 2.8 | Choices: no ← yes | 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.
description - |  | Description of the security group. Required when `state` is `present`.
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.
group_id - added in 2.4 |  | Id of group to delete (works only with absent). One of and only one of name or group_id is required.
name - |  | Name of the security group. One of and only one of name or group_id is required. Required if state=present.
profile string |  | Uses a boto profile. Only works with boto >= 2.24.0.
purge_rules boolean | Choices: no yes ← | Purge existing rules on security group that are not found in rules
purge_rules_egress boolean | Choices: no yes ← | Purge existing rules_egress on security group that are not found in rules_egress
purge_tags boolean added in 2.4 | Choices: no yes ← | If yes, existing tags will be purged from the resource to match exactly what is defined by tags parameter. If the tags parameter is not set then tags will not be modified.
region string |  | The AWS region to use. If not specified then the value of the AWS_REGION or EC2_REGION environment variable, if any, is used. See http://docs.aws.amazon.com/general/latest/gr/rande.html#ec2_region aliases: aws_region, ec2_region
rules - |  | List of firewall inbound rules to enforce in this group (see example). If none are supplied, no inbound rules will be enabled. Rules list may include its own name in `group_name`. This allows idempotent loopback additions (e.g. allow group to access itself). Rule sources list support was added in version 2.4. This allows to define multiple sources per source type as well as multiple source types per rule. Prior to 2.4 an individual source is allowed. In version 2.5 support for rule descriptions was added.
rules_egress - |  | List of firewall outbound rules to enforce in this group (see example). If none are supplied, a default all-out rule is assumed. If an empty list is supplied, no outbound rules will be enabled. Rule Egress sources list support was added in version 2.4. In version 2.5 support for rule descriptions was added.
security_token string |  | AWS STS security token. If not set then the value of the AWS_SECURITY_TOKEN or EC2_SECURITY_TOKEN environment variable is used. aliases: access_token
state - | Choices: present ← absent | Create or delete a security group
tags - added in 2.4 |  | A dictionary of one or more tags to assign to the security group.
validate_certs boolean | Choices: no yes ← | When set to "no", SSL certificates will not be validated for boto versions >= 2.6.0.
vpc_id - |  | ID of the VPC to create the group in.

## Notes

Note

- If a rule declares a group_name and that group doesn’t exist, it will be automatically created. In that case, group_desc should be provided as well. The module will refuse to create a depended-on group without a description.

- Preview diff mode support is added in version 2.7.

- 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
