## Parameters

Parameter | Choices/Defaults | Comments
--- | --- | ---

assign_public_ip
boolean

Choices:
- no
- yes

When provisioning within vpc, assign a public IP address. Boto library must be 2.13.0+.

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
count integer | Default: 1 | Number of instances to launch.
count_tag - |  | Used with 'exact_count' to determine how many nodes based on a specific tag criteria should be running. This can be expressed in multiple ways and is shown in the EXAMPLES section. For instance, one can request 25 servers that are tagged with "class=webserver". The specified tag must already exist or be passed in as the 'instance_tags' option.

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.

ebs_optimized
boolean

Choices:
- no ←
- yes

whether instance is using optimized EBS volumes, see https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/EBSOptimized.html.

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.
exact_count integer |  | An integer value which indicates how many instances that match the 'count_tag' parameter should be running. Instances are either created or terminated based on this value.
group list |  | Security group (or list of groups) to use with the instance. aliases: groups
group_id list |  | Security group id (or list of ids) to use with the instance.

id
string

Identifier for this instance or set of instances, so that the module will be idempotent with respect to EC2 instances.
This identifier is valid for at least 24 hours after the termination of the instance, and should not be reused for another call later on.
For details, see the description of client token at https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/Run_Instance_Idempotency.html.

image string / required |  | ami ID to use for the instance.
instance_ids list |  | list of instance ids, currently used for states: absent, running, stopped aliases: instance_id

instance_initiated_shutdown_behavior
string

Choices:
- stop ←
- terminate

Set whether AWS will Stop or Terminate an instance on shutdown. This parameter is ignored when using instance-store. images (which require termination on shutdown).

instance_profile_name string |  | Name of the IAM instance profile (i.e. what the EC2 console refers to as an "IAM Role") to use. Boto library must be 2.5.0+.
instance_tags dictionary |  | A hash/dictionary of tags to add to the new instance or for starting/stopping instance by tag; '{"key":"value"}' and '{"key":"value","key":"value"}'.
instance_type string / required |  | Instance type to use for the instance, see https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/instance-types.html.
kernel string |  | Kernel eki to use for the instance.
key_name string |  | key pair to use on the instance. The SSH key must exist on AWS in order to use this argument. If you want to generate keys from Ansible, take a look at `ec2_key` module. aliases: keypair

monitoring
boolean

Choices:
- no ←
- yes

Enable detailed monitoring (CloudWatch) for instance.

network_interfaces list |  | A list of existing network interfaces to attach to the instance at launch. When specifying existing network interfaces, none of the assign_public_ip, private_ip, vpc_subnet_id, group, or group_id parameters may be used. (Those parameters are for creating a new network interface at launch.) aliases: network_interface
placement_group string |  | Placement group for the instance when using EC2 Clustered Compute.
private_ip string |  | The private ip address to assign the instance (from the vpc subnet).
profile string |  | Uses a boto profile. Only works with boto >= 2.24.0.
ramdisk string |  | Ramdisk eri to use for the instance.
region string |  | The AWS region to use. Must be specified if ec2_url is not used. If not specified then the value of the `AWS_REGION` or `EC2_REGION` environment variable, if any, is used. See https://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

source_dest_check
boolean

Choices:
- no
- yes

Enable or Disable the Source/Destination checks (for NAT instances and Virtual Routers). When initially creating an instance the EC2 API defaults this to True.

spot_launch_group string |  | Launch group for spot request, see https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/how-spot-instances-work.html#spot-launch-group.
spot_price string |  | Maximum spot price to bid. If not set, a regular on-demand instance is requested. A spot request is made with this maximum bid. When it is filled, the instance is started.

spot_type
string

Choices:
- one-time ←
- persistent

Type of spot request; one of "one-time" or "persistent". Defaults to "one-time" if not supplied.

spot_wait_timeout integer | Default: 600 | How long to wait for the spot instance request to be fulfilled. Affects 'Request valid until' for setting spot request lifespan.

state
string

Choices:
- absent
- present ←
- restarted
- running
- stopped

Create, terminate, start, stop or restart instances. The state 'restarted' was added in Ansible 2.2.
When 'absent', instance_ids is required.
When 'running', 'stopped' and 'restarted', instance_ids or instance_tags is required.

tenancy
string

Choices:
- default ←
- dedicated

An instance with a tenancy of "dedicated" runs on single-tenant hardware and can only be launched into a VPC.
Note that to use dedicated tenancy you MUST specify a vpc_subnet_id as well.
Dedicated tenancy is not available for EC2 "micro" instances.

termination_protection
boolean

Choices:
- no ←
- yes

Enable or Disable the Termination Protection.

user_data string |  | Opaque blob of data which is made available to the EC2 instance.

validate_certs

Choices:
- no
- yes ←

When set to "no", SSL certificates will not be validated for boto versions >= 2.6.0.

volumes
list

a list of hash/dictionaries of volumes to add to the new instance; '[{"key":"value", "key":"value"}]'; keys allowed are - device_name (str; required), delete_on_termination (bool; False), ephemeral (str), encrypted (bool; False), snapshot (str), volume_type (str), volume_size (int, GiB), iops (int) - iops must be set when volume_type='io1', ephemeral and snapshot are mutually exclusive.

vpc_subnet_id string |  | the subnet ID in which to launch the instance (VPC).

wait
boolean

Choices:
- no ←
- yes

Wait for the instance to reach its desired state before returning.
Does not wait for SSH, see 'wait_for_connection' example for details.

wait_timeout integer | Default: 300 | How long before wait gives up, in seconds.
zone string |  | AWS availability zone in which to launch the instance. 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
