Connection module for Amazon EC2
.. versionadded:: 2015.8.0
:configuration: This module accepts explicit EC2 credentials but can also
utilize IAM roles assigned to the instance through Instance Profiles.
Dynamic credentials are then automatically obtained from AWS API and no
further configuration is necessary. More Information available here__.
.. __: http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/iam-roles-for-amazon-ec2.html
If IAM roles are not used you need to specify them either in a pillar or
in the minion's config file:
.. code-block:: yaml
ec2.keyid: GKTADJGHEIQSXMKKRBJ08H
ec2.key: askdjghsdfjkghWupUjasdflkdfklgjsdfjajkghs
A region may also be specified in the configuration:
.. code-block:: yaml
ec2.region: us-east-1
If a region is not specified, the default is us-east-1.
It's also possible to specify key, keyid, and region via a profile, either
as a passed in dict, or as a string to pull from pillars or minion config:
.. code-block:: yaml
myprofile:
keyid: GKTADJGHEIQSXMKKRBJ08H
key: askdjghsdfjkghWupUjasdflkdfklgjsdfjajkghs
region: us-east-1

"""
Create and start an EC2 instance.
Returns True if the instance was created; otherwise False.
CLI Example:
.. code-block:: bash
salt myminion boto_ec2.run ami-b80c2b87 name=myinstance
image_id
(string) β The ID of the image to run.
name
(string) - The name of the instance.
tags
(dict of key: value pairs) - tags to apply to the instance.
key_name
(string) β The name of the key pair with which to launch instances.
security_groups
(list of strings) β The names of the EC2 classic security groups with
which to associate instances
user_data
(string) β The Base64-encoded MIME user data to be made available to the
instance(s) in this reservation.
instance_type
(string) β The type of instance to run. Note that some image types
(e.g. hvm) only run on some instance types.
placement
(string) β The Availability Zone to launch the instance into.
kernel_id
(string) β The ID of the kernel with which to launch the instances.
ramdisk_id
(string) β The ID of the RAM disk with which to launch the instances.
monitoring_enabled
(bool) β Enable detailed CloudWatch monitoring on the instance.
vpc_id
(string) - ID of a VPC to bind the instance to. Exclusive with vpc_name.
vpc_name
(string) - Name of a VPC to bind the instance to. Exclusive with vpc_id.
subnet_id
(string) β The subnet ID within which to launch the instances for VPC.
subnet_name
(string) β The name of a subnet within which to launch the instances for VPC.
private_ip_address
(string) β If youβre using VPC, you can optionally use this parameter to
assign the instance a specific available IP address from the subnet
(e.g. 10.0.0.25).
block_device_map
(boto.ec2.blockdevicemapping.BlockDeviceMapping) β A BlockDeviceMapping
data structure describing the EBS volumes associated with the Image.
(string) - A string representation of a BlockDeviceMapping structure
(dict) - A dict describing a BlockDeviceMapping structure
YAML example:
.. code-block:: yaml
device-maps:

ephemeral_name: ephemeral2
/dev/sde:
ephemeral_name: ephemeral3
/dev/sdf:
size: 20
volume_type: gp2
disable_api_termination
(bool) β If True, the instances will be locked and will not be able to
be terminated via the API.
instance_initiated_shutdown_behavior
(string) β Specifies whether the instance stops or terminates on
instance-initiated shutdown. Valid values are: stop, terminate
placement_group
(string) β If specified, this is the name of the placement group in
which the instance(s) will be launched.
client_token
(string) β Unique, case-sensitive identifier you provide to ensure
idempotency of the request. Maximum 64 ASCII characters.
security_group_ids
(list of strings) β The ID(s) of the VPC security groups with which to
associate instances.
security_group_names
(list of strings) β The name(s) of the VPC security groups with which to
associate instances.
additional_info
(string) β Specifies additional information to make available to the
instance(s).
tenancy
(string) β The tenancy of the instance you want to launch. An instance
with a tenancy of βdedicatedβ runs on single-tenant hardware and can
only be launched into a VPC. Valid values are:βdefaultβ or βdedicatedβ.
NOTE: To use dedicated tenancy you MUST specify a VPC subnet-ID as well.
instance_profile_arn
(string) β The Amazon resource name (ARN) of the IAM Instance Profile
(IIP) to associate with the instances.
instance_profile_name
(string) β The name of the IAM Instance Profile (IIP) to associate with
the instances.
ebs_optimized
(bool) β Whether the instance is optimized for EBS I/O. This
optimization provides dedicated throughput to Amazon EBS and an
optimized configuration stack to provide optimal EBS I/O performance.
This optimization isnβt available with all instance types.
network_interfaces
(boto.ec2.networkinterface.NetworkInterfaceCollection) β A
NetworkInterfaceCollection data structure containing the ENI
specifications for the instance.
network_interface_id
(string) - ID of the network interface to attach to the instance
network_interface_name
(string) - Name of the network interface to attach to the instance

tag_maps (list)
List of dicts of filters and tags, where 'filters' is a dict suitable for passing to the
'filters' argument of get_all_volumes() above, and 'tags' is a dict of tags to be set on
volumes (via create_tags/delete_tags) as matched by the given filters. The filter syntax
is extended to permit passing either a list of volume_ids or an instance_name (with
instance_name being the Name tag of the instance to which the desired volumes are mapped).
Each mapping in the list is applied separately, so multiple sets of volumes can be all
tagged differently with one call to this function. If filtering by instance Name, You may
additionally limit the instances matched by passing in a list of desired instance states.
The default set of states is ('pending', 'rebooting', 'running', 'stopping', 'stopped').
