## Synopsis

- Read the AWS documentation for Network ACLS https://docs.aws.amazon.com/AmazonVPC/latest/UserGuide/VPC_ACLs.html

## Requirements

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

- boto
- boto3
- botocore
- json
- 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.
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.
egress - | Default: [] | A list of rules for outgoing traffic. Each rule must be specified as a list. Each rule may contain the rule number (integer 1-32766), protocol (one of ['tcp', 'udp', 'icmp', '-1', 'all']), the rule action ('allow' or 'deny') the CIDR of the IPv4 network range to allow or deny, the ICMP type (-1 means all types), the ICMP code (-1 means all codes), the last port in the range for TCP or UDP protocols, and the first port in the range for TCP or UDP protocols. See examples.
ingress - | Default: [] | List of rules for incoming traffic. Each rule must be specified as a list. Each rule may contain the rule number (integer 1-32766), protocol (one of ['tcp', 'udp', 'icmp', '-1', 'all']), the rule action ('allow' or 'deny') the CIDR of the IPv4 network range to allow or deny, the ICMP type (-1 means all types), the ICMP code (-1 means all codes), the last port in the range for TCP or UDP protocols, and the first port in the range for TCP or UDP protocols. See examples.
nacl_id - added in 2.4 |  | NACL id identifying a network ACL. One and only one of the name or nacl_id is required.
name - |  | Tagged name identifying a network ACL. One and only one of the name or nacl_id is required.
profile string |  | Uses a boto profile. Only works with boto >= 2.24.0.
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
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 | Creates or modifies an existing NACL Deletes a NACL and reassociates subnets to the default NACL
subnets - |  | The list of subnets that should be associated with the network ACL. Must be specified as a list Each subnet can be specified as subnet ID, or its tagged name.
tags - |  | Dictionary of tags to look for and apply when creating a network ACL.
validate_certs boolean | Choices: no yes ← | When set to "no", SSL certificates will not be validated for boto versions >= 2.6.0.
vpc_id - |  | VPC id of the requesting VPC. Required when state present.

## 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
