Types

type AutoScaling

type AutoScaling struct {
	aws.Auth
	aws.Region
}

AutoScaling contains the details of the AWS region to perform operations against.

func New

func New(auth aws.Auth, region aws.Region) *AutoScaling

New creates a new AutoScaling

func (*AutoScaling) CreateAutoScalingGroup

func (as *AutoScaling) CreateAutoScalingGroup(ag AutoScalingGroup) (
	resp *AutoScalingGroupsResp, err error)

CreateAutoScalingGroup creates a new autoscaling group.

func (*AutoScaling) CreateLaunchConfiguration

func (as *AutoScaling) CreateLaunchConfiguration(lc LaunchConfiguration) (
	resp *CreateLaunchConfigurationResp, err error)

CreateLaunchConfiguration creates a new launch configuration.

func (*AutoScaling) DeleteScheduledAction

func (as *AutoScaling) DeleteScheduledAction(rp DeleteScheduledActionRequestParams) (
	resp *SimpleResp, err error)

DeleteScheduledAction deletes a scheduled action.

func (*AutoScaling) DescribeAutoScalingGroups

func (as *AutoScaling) DescribeAutoScalingGroups(groupnames []string) (
	resp *AutoScalingGroupsResp, err error)

DescribeAutoScalingGroups returns details about the groups provided in the list. If the list is nil information is returned about all the groups in the region.

func (*AutoScaling) DescribeLaunchConfigurations

func (as *AutoScaling) DescribeLaunchConfigurations(confnames []string) (
	resp *LaunchConfigurationResp, err error)

DescribeLaunchConfigurations returns details about the launch configurations supplied in the list. If the list is nil, information is returned about all launch configurations in the region.

func (*AutoScaling) DescribeScheduledActions

func (as *AutoScaling) DescribeScheduledActions(rp ScheduledActionsRequestParams) (
	resp *DescribeScheduledActionsResult, err error)

DescribeScheduledActions returns a list of the current scheduled actions. If the AutoScalingGroup name is provided it will list all the scheduled actions for that group.

func (*AutoScaling) PutScheduledUpdateGroupAction

func (as *AutoScaling) PutScheduledUpdateGroupAction(rp PutScheduledActionRequestParams) (
	resp *SimpleResp, err error)

PutScheduledUpdateGroupAction creates or updates a scheduled scaling action for an AutoScaling group. Scheduled actions can be made up to thirty days in advance. When updating a scheduled scaling action, if you leave a parameter unspecified, the corresponding value remains unchanged in the affected AutoScaling group.

Auto Scaling supports the date and time expressed in "YYYY-MM-DDThh:mm:ssZ" format in UTC/GMT only.

func (*AutoScaling) ResumeProcesses

func (as *AutoScaling) ResumeProcesses(ag AutoScalingGroup, processes []string) (
	resp *SimpleResp, err error)

ResumeProcesses resumes the scaling processes for the scaling group. If no processes are provided, all processes are resumed.

func (*AutoScaling) SetDesiredCapacity

func (as *AutoScaling) SetDesiredCapacity(rp SetDesiredCapacityRequestParams) (resp *SimpleResp, err error)

SetDesiredCapacity changes the DesiredCapacity of an AutoScaling group.

func (*AutoScaling) SuspendProcesses

func (as *AutoScaling) SuspendProcesses(ag AutoScalingGroup, processes []string) (
	resp *SimpleResp, err error)

SuspendProcesses suspends the processes for the autoscaling group. If no processes are provided, all processes are suspended.

If you suspend either of the two primary processes (Launch or Terminate), this can prevent other process types from functioning properly.

func (*AutoScaling) UpdateAutoScalingGroup

func (as *AutoScaling) UpdateAutoScalingGroup(ag AutoScalingGroup) (resp *SimpleResp, err error)

UpdateAutoScalingGroup updates the scaling group.

To update an auto scaling group with a launch configuration that has the InstanceMonitoring flag set to False, you must first ensure that collection of group metrics is disabled. Otherwise calls to UpdateAutoScalingGroup will fail.
