- Synopsis

- Requirements

- Parameters

- Notes

- Examples

- Return Values

- Status

## Synopsis

- creates an EBS volume and optionally attaches it to an instance. If both an instance ID and a device name is given and the instance has a device at the device name, then no volume is created and no attachment is made. This module has a dependency on python-boto.

## Requirements

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

- python >= 2.6

- boto

## 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.
delete_on_termination boolean | Choices: no ← yes | When set to "yes", the volume will be deleted upon instance termination.
device_name - |  | device id to override device mapping. Assumes /dev/sdf for Linux/UNIX and /dev/xvdf for Windows.
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.
encrypted boolean | Choices: no ← yes | Enable encryption at rest for this volume.
id - |  | volume id if you wish to attach an existing volume (requires instance) or remove an existing volume
instance - |  | instance ID if you wish to attach the volume. Since 1.9 you can set to None to detach.
iops - | Default: 100 | the provisioned IOPs you want to associate with this volume (integer).
kms_key_id - |  | Specify the id of the KMS key to use.
name - |  | volume Name tag if you wish to attach an existing volume (requires instance)
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
snapshot - |  | snapshot ID on which to base the volume
state - | Choices: absent present ← list | whether to ensure the volume is present or absent, or to list existing volumes (The `list` option was added in version 1.8).
tags - | Default: {} | tag:value pairs to add to the volume after creation
validate_certs boolean | Choices: no yes ← | When set to "no", SSL certificates will not be validated for boto versions >= 2.6.0.
volume_size - |  | size of volume (in GiB) to create.
volume_type - | Default: "standard" | Type of EBS volume; standard (magnetic), gp2 (SSD), io1 (Provisioned IOPS), st1 (Throughput Optimized HDD), sc1 (Cold HDD). "Standard" is the old EBS default and continues to remain the Ansible default for backwards compatibility.
zone - |  | zone in which to create the volume, if unset uses the zone the instance is in (if set) aliases: aws_zone, ec2_zone

## 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

## Examples

    # Simple attachment action
    - ec2_vol:
        instance: XXXXXX
        volume_size: 5
        device_name: sdd

    # Example using custom iops params
    - ec2_vol:
        instance: XXXXXX
        volume_size: 5
        iops: 100
        device_name: sdd

    # Example using snapshot id
    - ec2_vol:
        instance: XXXXXX
        snapshot: "{{ snapshot }}"

    # Playbook example combined with instance launch
    - ec2:
        keypair: "{{ keypair }}"
        image: "{{ image }}"
        wait: yes
        count: 3
      register: ec2
    - ec2_vol:
        instance: "{{ item.id }}"
        volume_size: 5
      loop: "{{ ec2.instances }}"
      register: ec2_vol

    # Example: Launch an instance and then add a volume if not already attached
    #   * Volume will be created with the given name if not already created.
    #   * Nothing will happen if the volume is already attached.
    #   * Requires Ansible 2.0

    - ec2:
        keypair: "{{ keypair }}"
        image: "{{ image }}"
        zone: YYYYYY
        id: my_instance
        wait: yes
        count: 1
      register: ec2

    - ec2_vol:
        instance: "{{ item.id }}"
        name: my_existing_volume_Name_tag
        device_name: /dev/xvdf
      loop: "{{ ec2.instances }}"
      register: ec2_vol

    # Remove a volume
    - ec2_vol:
        id: vol-XXXXXXXX
        state: absent

    # Detach a volume (since 1.9)
    - ec2_vol:
        id: vol-XXXXXXXX
        instance: None

    # List volumes for an instance
    - ec2_vol:
        instance: i-XXXXXX
        state: list

    # Create new volume using SSD storage
    - ec2_vol:
        instance: XXXXXX
        volume_size: 50
        volume_type: gp2
        device_name: /dev/xvdf

    # Attach an existing volume to instance. The volume will be deleted upon instance termination.
    - ec2_vol:
        instance: XXXXXX
        id: XXXXXX
        device_name: /dev/sdf
        delete_on_termination: yes
