#associate_address(options = {}) ⇒ Object

The AssociateAddress operation associates an elastic IP address with an instance.

If the IP address is currently assigned to another instance, the IP address is assigned to the new instance. This is an idempotent operation. If you enter it more than once, Amazon EC2 does not return an error.

Parameters:

  • options (Hash) (defaults to: {}) —

    a customizable set of options

Options Hash (options):

  • :instance_id (String) — default: '' —

    the instance ID to associate an IP with.

  • :public_ip (String) — default: '' —

    the public IP to associate an instance with.

end

#authorize_security_group_ingress(options = {}) ⇒ Object

The AuthorizeSecurityGroupIngress operation adds permissions to a security group.

Permissions are specified in terms of the IP protocol (TCP, UDP or ICMP), the source of the request (by IP range or an Amazon EC2 user-group pair), source and destination port ranges (for TCP and UDP), and ICMP codes and types (for ICMP). When authorizing ICMP, -1 may be used as a wildcard in the type and code fields.

Permission changes are propagated to instances within the security group being modified as quickly as possible. However, a small delay is likely, depending on the number of instances that are members of the indicated group.

When authorizing a user/group pair permission, GroupName, SourceSecurityGroupName and SourceSecurityGroupOwnerId must be specified. When authorizing a CIDR IP permission, GroupName, IpProtocol, FromPort, ToPort and CidrIp must be specified. Mixing these two types of parameters is not allowed.

Parameters:

  • options (Hash) (defaults to: {}) —

    a customizable set of options

Options Hash (options):

  • :group_name (String) — default: ""
  • :ip_protocol (optional, String) — default: nil —

    Required when authorizing CIDR IP permission

  • :from_port (optional, Integer) — default: nil —

    Required when authorizing CIDR IP permission

  • :to_port (optional, Integer) — default: nil —

    Required when authorizing CIDR IP permission

  • :cidr_ip (optional, String) — default: nil —

    Required when authorizing CIDR IP permission

  • :source_security_group_name (optional, String) — default: nil —

    Required when authorizing user group pair permissions

  • :source_security_group_owner_id (optional, String) — default: nil —

    Required when authorizing user group pair permissions

#create_image(options = {}) ⇒ Object

Creates an AMI that uses an Amazon EBS root device from a “running” or “stopped” instance.

AMIs that use an Amazon EBS root device boot faster than AMIs that use instance stores. They can be up to 1 TiB in size, use storage that persists on instance failure, and can be stopped and started.

Parameters:

  • options (Hash) (defaults to: {}) —

    a customizable set of options

Options Hash (options):

  • :instance_id (String) — default: "" —

    The ID of the instance.

  • :name (String) — default: "" —

    The name of the AMI that was provided during image creation. Constraints 3-128 alphanumeric characters, parenthesis (()), commas (,), slashes (/), dashes (-), or underscores(_)

  • :description (optional, String) — default: "" —

    The description of the AMI that was provided during image creation.

  • :no_reboot (optional, Boolean) — default: false —

    By default this property is set to false, which means Amazon EC2 attempts to cleanly shut down the instance before image creation and reboots the instance afterwards. When set to true, Amazon EC2 does not shut down the instance before creating the image. When this option is used, file system integrity on the created image cannot be guaranteed.

end

#create_security_group(options = {}) ⇒ Object

The CreateSecurityGroup operation creates a new security group. Every instance is launched in a security group. If none is specified as part of the launch request then instances are launched in the default security group. Instances within the same security group have unrestricted network access to one another. Instances will reject network access attempts from other instances in a different security group. As the owner of instances you may grant or revoke specific permissions using the AuthorizeSecurityGroupIngress and RevokeSecurityGroupIngress operations.

#describe_images(options = {}) ⇒ Object

The DescribeImages operation returns information about AMIs available for use by the user. This includes both public AMIs (those available for any user to launch) and private AMIs (those owned by the user making the request and those owned by other users that the user making the request has explicit launch permissions for).

The list of AMIs returned can be modified via optional lists of AMI IDs, owners or users with launch permissions. If all three optional lists are empty all AMIs the user has launch permissions for are returned. Launch permissions fall into three categories:

Launch Permission Description

public - The all group has launch permissions for the AMI. All users have launch permissions for these AMIs. explicit - The owner of the AMIs has granted a specific user launch permissions for the AMI. implicit - A user has implicit launch permissions for all AMIs he or she owns.

If one or more of the lists are specified the result set is the intersection of AMIs matching the criteria of the individual lists.

Providing the list of AMI IDs requests information for those AMIs only. If no AMI IDs are provided, information of all relevant AMIs will be returned. If an AMI is specified that does not exist a fault is returned. If an AMI is specified that exists but the user making the request does not have launch permissions for, then that AMI will not be included in the returned results.

Providing the list of owners requests information for AMIs owned by the specified owners only. Only AMIs the user has launch permissions for are returned. The items of the list may be account ids for AMIs owned by users with those account ids, amazon for AMIs owned by Amazon or self for AMIs owned by the user making the request.

The executable list may be provided to request information for AMIs that only the specified users have launch permissions for. The items of the list may be account ids for AMIs owned by the user making the request that the users with the specified account ids have explicit launch permissions for, self for AMIs the user making the request has explicit launch permissions for or all for public AMIs.

Deregistered images will be included in the returned results for an unspecified interval subsequent to deregistration.

Parameters:

  • options (Hash) (defaults to: {}) —

    a customizable set of options

Options Hash (options):

  • :image_id (Array) — default: []
  • :owner_id (Array) — default: []

The image manifest is retrieved once and stored within the Amazon EC2 network. Any modifications to an image in Amazon S3 invalidate this registration. If you do have to make changes and upload a new image deregister the previous image and register the new image.

Parameters:

  • options (Hash) (defaults to: {}) —

    a customizable set of options

Options Hash (options):

  • :image_location (String) — default: ""

#release_address(options = {}) ⇒ Object

The ReleaseAddress operation releases an elastic IP address associated with your account.

If you run this operation on an elastic IP address that is already released, the address might be assigned to another account which will cause Amazon EC2 to return an error.

Note : Releasing an IP address automatically disassociates it from any instance with which it is associated. For more information, see DisassociateAddress.

Important! After releasing an elastic IP address, it is released to the IP address pool and might no longer be available to your account. Make sure to update your DNS records and any servers or devices that communicate with the address.

Parameters:

  • options (Hash) (defaults to: {}) —

    a customizable set of options

Options Hash (options):

  • :public_ip (String) — default: '' —

    an IP address to be released.

#revoke_security_group_ingress(options = {}) ⇒ Object

The RevokeSecurityGroupIngress operation revokes existing permissions that were previously granted to a security group. The permissions to revoke must be specified using the same values originally used to grant the permission.

Permissions are specified in terms of the IP protocol (TCP, UDP or ICMP), the source of the request (by IP range or an Amazon EC2 user-group pair), source and destination port ranges (for TCP and UDP), and ICMP codes and types (for ICMP). When authorizing ICMP, -1 may be used as a wildcard in the type and code fields.

Permission changes are propagated to instances within the security group being modified as quickly as possible. However, a small delay is likely, depending on the number of instances that are members of the indicated group.

When revoking a user/group pair permission, GroupName, SourceSecurityGroupName and SourceSecurityGroupOwnerId must be specified. When authorizing a CIDR IP permission, GroupName, IpProtocol, FromPort, ToPort and CidrIp must be specified. Mixing these two types of parameters is not allowed.

Parameters:

  • options (Hash) (defaults to: {}) —

    a customizable set of options

Options Hash (options):

  • :group_name (String) — default: ""
  • :ip_protocol (optional, String) — default: nil —

    Required when revoking CIDR IP permission

  • :from_port (optional, Integer) — default: nil —

    Required when revoking CIDR IP permission

  • :to_port (optional, Integer) — default: nil —

    Required when revoking CIDR IP permission

  • :cidr_ip (optional, String) — default: nil —

    Required when revoking CIDR IP permission

  • :source_security_group_name (optional, String) — default: nil —

    Required when revoking user group pair permissions

  • :source_security_group_owner_id (optional, String) — default: nil —
